IDENTIFICATION AND TABULATION OF GEOLOGICAL CONTACTS

IN THE EDWARDS AQUIFER, SAN ANTONIO AREA, TEXAS

By

Ted A. Small U.S. Geological Survey

ABSTRACT

Geological contacts were picked on logs of about 480 wells in the San Antonio area of the Edwards aquifer. The base of the Del Rio Clay is the most frequently picked contact because it is the top of the Edwards aquifer and also because it is easily identified on either gamma-ray or electric logs.

Other important formation contacts identified were the Austin Group, the Eagle Ford Group, the Buda Limestone, and the Glen Rose Formation. These con­ tacts were usually easy to identify on either gamma-ray or electric logs.

INTRODUCTION

This report describes the identification of geologic contacts and compiles the picks from well and test-hole data compiled from 1970 to 1978 by the U.S. Geological Survey as part of a study of the Edwards aquifer in the San Antonio area, Texas. The study was made in cooperation with the San Antonio City Water Board and the Texas Department of Water Resources. These picks were used to prepare geologic cross sections and a structural contour map of the top of the Edwards aquifer (Maclay and Small, 1983).

Location of the San Antonio Area

The San Antonio area of the Edwards aquifer is in the Balcones Fault Zone and includes parts of Kinney, Uvalde, Medina, Bexar, Coma! and Hays Counties. The location and the hydro!ogic features of the San Antonio area is shown in figure 1.

Source of Data

The documented geophysical logs are filed in the Geological Survey's San Antonio Subdistrict Office. Many of the logs were recorded by Geological Sur­ vey equipment and personnel. The remainder were obtained from outside sources, such as private companies and governmental agencies. The availability of the geophysical logs is documented in Maclay, Small, and Rettman (1981).

Well-Numbering and Well-Location System

The location of wells or test holes having geophysical logs with identi­ fiable contacts is shown in figure 2. The wells and test holes are identified by the standard we!1-numbering system used by the Texas Department of Water Resources.

.The well-numbering system in Texas was developed by the Texas Department of Water Resources for use throughout the State. Under this system, each 1- degree quadrangle is given a number consisting of two digits. These are the first two digits in the well number. Each 1-degree quadrangle is divided into 7-1/2-minute quadrangles which are given two-digit numbers from 01 to 64. These are the third and fourth digits of the well number. Each 7-1/2-minute quadrangle is divided into 2-1/2-minute quadrangles which are given a single- digit number from 1 to 9. This is the fifth digit of the well number. Final­ ly, each well within a 2-1/2-minute quadrangle is given a two-digit number in the order in which it was inventoried, starting with 01. These are the last two digits of the well number. Only the last three digits of the well number are shown at each well site; the middle two digits are shown in the northwest corner of each 7-1/2-minute quadrangle. In .addition to the seven-digit number, a two-letter prefix is used to identify the county. The prefixes for counties where well logs were used for correlation are as follows: AY, Bexar; DX, Comal; KX, Guadalupe; LR, Hays; RP, Kinney; TD, Medina; and YP, Uvalde. An example of a well numbered by this system is AY-68-27-906.

Since this well-numbering system will locate a well only to a 2-1/2- minute quadrangle, the latitude and longitude also are given so that the well can be precisely located as shown in figure 3.

STRATIGRAPHIC UNITS

The strati graphic names used in this report are from the Geologic Atlas of Texas, San Antonio sheet (University of Texas, Bureau of Economic Geology, 1974). The stratigraphic nomenclature proposed by Rose (1972) is used to describe the geologic units of the Maverick Basin, the Devils River Trend, and the San Marcos Platform (fig. 4) and does not follow the usage of the U.S. Geological Survey. The correlation of the stratigraphic units is shown in figure 5.

Overlying the Edwards Aquifer

The formations overlying the Edwards that will be discussed in this report are, in descending order, the Austin Group, Eagle Ford Group, Buda Limestone, and the Del Rio Clay.

The Austin Group is a white to buff, dense, chalky limestone. It is about 150 feet thick in much of the eastern area and central part of the San Antonio area and thickens to more than 1,000 feet in Kinney County, where it is a mas­ sive limestone in the lower part and a thin-bedded chalky limestone and marl in the upper part (Bennett and Sayre, 1962).

The Eagle Ford Group is the basal unit of the Gulf Series or Upper Cre­ taceous. It is .chiefly flaggy, calcareous, and sandy shale interbedded with hard, shaly limestone (Arnow, 1959). It is about 35 feet thick in the eastern part of the study area and over 200 feet thick in the west where it is a fla§9y» crystalline limestone and clayey, chalky limestone interbedded with layers of marl (Bennett and Sayre, 1962).

'The Buda Limestone is the top formation of the Washita Group and is a very hard, dense, massive limestone (Holt, 1956). It is about 55 feet thick in the east and more than 100 feet thick in the west.

The Del Rio Clay overlies the Georgetown Formation, both of the Washita Group, within the San Marcos Platform, the Devils River Limestone within the Devils River Trend, and the Salmon Peak Formation within the Maverick Basin. It is a soft, sticky calcareous clay that is about 50 feet thick in the eastern and central part of the San Antonio area. In the western part of the San Antonio area, the Del Rio Clay also contains thin, flaggy beds of limestone interbedded with clay. The Del Rio Clay thickens to the west and according to Welder and Reeves (1962), is about 120 feet thick at the Uvalde-Kinney County line and more than 200 feet thick in southwestern Kinney County (Bennett and Sayre, 1962).

Within the Edwards Aquifer San Marcos Platform

The Georgetown Formation of the Washita Group overlies the Edwards Group (Rose, 1972) on the San Marcos Platform. It is a dense, shaly, lime mudstone (see table 1 for carbonate identification system used in this report) and/or wackestone. The formation is about 20 to 30 feet thick.

The Edwards Group (Rose, 1972) consists of two formations, the Person (upper) and the Kainer (lower). The Person Formation is about 180 feet thick and was divided by Rose (1972) into five units: The Cyclic member, the Marine member, the Collapsed member, the Leached member, and the Regional dense member. The Cyclic member is not present or is not distinguishable within the aquifer. The Marine member is a dense, lime mudstone about 80 feet thick. The Leached member and the Collapsed member are dense, variably recrystallized lime wacke­ stone and lime grainstones about 80 feet thick. The Regional dense member is the basal unit and is a dense, clayey, lime mudstone about 20 feet thick. The Kainer Formation is about 250 feet thick and consists of four members. The Grainstone member is the upper member and is a well-cemented, miliolid lime grainstone about 60 feet thick. The Kirschberg evaporite is stratigraphically below and is a recrystallized, variably honeycombed, crystalline limestone about 50 feet thick. The Dolomitic member is a variably recrystallized, honey­ combed, crystalline, dolomitic limestone or crystalline dolomite. The Dolo­ mitic member is about 90 feet thick. The Basal nodular member is the lowest member and is a dense, shaly, lime wackestone about 50 feet thick. The Cyclic, Marine, Leached, and Collapsed members of the Person Formation are not readily identifiable and are not picked.

Devils River Trend

The Devils River Trend refers to the belt of strati graphically inseparable Fredericksburg and Washita rocks bordering the northern Maverick Basin (Lozo and Smith, 1964). These Edwards facies rocks are known as the Devils River Limestone and are chiefly recrystallized miliolid and shell fragment, lime grains,tones and wackestones about 450 to 600 feet thick.

M

Maverick Basin

The rocks equivalent to the Edwards in the Maverick Basin are divided into the Salmon Peak Formation, the McKnight Formation, and the West Nueces Formation (Lozo and Smith, 1964). The Salmon Peak Formation, the upper unit of the Maverick Basin, is a dense, massive lime mudstone about 350 feet thick. The McKnight Formation is a thin-bedded lime mudstone and shale, about 100 to 200 feet thick. The West Nueces Formation consists of a lower nodular, lime wackestone about 60 feet thick and an upper massive, dense, lime mudstone about 60 feet thick.

Underlying the Edwards Aquifer

The Glen Rose Formation, which is the confining unit below the Edwards aquifer, consists of beds of massive, chalky limestone alternating with beds of marly limestone (Livingston, Sayre, and White, 1936).

IDENTIFICATION OF STRATIGRAPHIC CONTACTS Overlying the Edwards Aquifer

The electrical properties of the Austin Group, Eagle Ford Group, Buda Limestone, and Del Rio Clay are illustrated on the partial electric log of well AY-68-36-206 (fig. 6).

The representative pattern for the resistivity curve for the formations from the Austin Group to the Del Rio Clay is as follows: A high uneven resis­ tivity zone for the Austin; a low resistivity zone commonly containing two deep reentrants for the Eagle Ford; a broad zone of high resistivity of some variation for the Buda; and a zone of deeply suppressed resistivity of little variation for the Del Rio.

The normal resistivity curve shows an abrupt shift from a low resistivity (10 ohmmeters) within the basal Anacacho Limestone to a broad unevenly elevated pattern of higher resistivity that ranges from 50 to 90 ohmmeters in the Austin Group. The top of the Austin is picked at this shift. About 150 feet below the top of the Austin, the resistivity shifts to about 20-40 ohmmeters. The top of the Eagle Ford Group is picked at this shift. Approximately 30 feet below the top of the Eagle Ford, the resistivity curve shifts sharply to a high of about 90 ohmmeters. The top of the Buda is picked where the curve shifts to the high resistivity value. About 60 feet below the top of the Buda, the curve shows a shift to a resistivity of about 10 ohmmeters and this lower resistivity marks the Del Rio Clay. The top of the Del Rio Clay is picked where the curve becomes recessive and the base is picked about 55 feet below the top where the resistivity curve shifts sharply to the high resistivity of the Georgetown Formation.

The above mentioned high, low, high pattern of the resistivity curve is offset by a spontaneous potential (SP) curve that is a flattened (no high peaks or deep valleys) mirror image of the resistivity curve. The SP curve shows a negative (to the left) shift of about 15 millivolts at the contact of the Anacacho and the Austin. This is followed by a positive (to the right) shift of 10-20 millivolts at the top of the Eagle Ford and a negative shift of about 15 millivolts at the top of the Buda. There is a positive shift of about'15 millivolts at the top of the Del Rio and a negative shift of about 15 millivolts at the base of the Del Rio.

The gamma-ray curve in figure 7, partial gamma-ray log of well AY-68-30- 807, shows the natural gamma radiation properties of the Austin Group, the Eagle Ford Group, the Buda Limestone, the Del Rio Clay, the Georgetown Forma­ tion, the Person Formation and the Kainer Formation. The typical pattern of gamma-ray curve for the formations from the Austin Group through the Del Rio Clay is as follows: A broad zone of relatively low radiation in the Austin; a very high spiky peak of high radiation in the Eagle Ford; low radiation in the Buda; and a zone of high spiky peaks of high radiation in the Del Rio.

*The gamma-ray curve shows that the Austin has lower natural gamma radia­

tion, 15-30 counts per second (cps), than that of the overlying Anacacho which has about 60 cps. The top of the Austin is picked where the curve shifts to the left (toward lower radiation) in the Austin. About 210 feet below the top of the Austin, the curve deflects sharply to the right, showing a pattern of three high spiky peaks, having radiation of about 70 to 100 cps in the Eagle

Ford. The top of the Eagle Ford is picked where the curve shifts to the right. About 30 feet below the top of the Eagle Ford, the curve kicks back to the left to low radiation of about 20 cps. The top of the Buda is picked where the curve shifts back to low radiation. Approximately 55 feet below the top of the Buda, the curve deflects sharply to the right, to a series of high spiky peaks of about 60-65 cps. This series of peaks represents the Del Rio Clay. The top is picked where the curve deflects to the right to form the series, and the base is picked about 50 to 55 feet below the top where the curve shifts back to the left to the lower radiation of the Georgetown Formation.

The electrical properties of the Austin Group, Eagle Ford Group, Buda Limestone, Del Rio Clay, and the Devils River Limestone in the Devils River Trend are shown in the induction-electric log of well TD-69-53-6 (fig. 8), and the natural gamma-radiation properties of these formations are shown in the gamma-ray log of well YP-69-37-402 (fig. 9).

The typical resistivity, SP, and gamma-ray radiation curves for the Aus­ tin, Eagle Ford, Buda, and Del Rio in the Devils River Trend are very similar In shape to those already described for the San Marcos Platform, and the cri­ teria for picking the contacts are about the same. The formations are a little thicker in the Devils River Trend.

The electrical properties of the Austin Group, the Eagle Ford Group, the Buda Limestone, the Del Rio Clay, the Salmon Peak Formation, the McKnight For­ mation, and the West Nueces Formation in the Maverick Basin are shown in the induction-electric log of well RP-70-54-5 (fig. 10), and the natural gamma- ray properties of these formations are shown in the gamma-ray sonic log of well RP-70-44-8 (fig. 11)

The criteria for picking the contacts of the formations overlying the Edwards in the Maverick Basin are similar to the criteria used for picking the same contacts in the San Marcos Platform area. The shape of the SP-resistivity curve in figure 10 is not the same for the Austin-Eagle Ford as SP-resistivity curves in the San Marcos Platform area, but the contacts are not difficult to pick. The Buda-Del Rio pattern is much the same as it is on the San Marcos Platform. The pattern of the gamma-ray curve in figure 11 for the formations overlying the Edwards is similar to gamma-ray curves for the same formations In the San Marcos Platform area and the criteria for picking the formation contacts are the same.

Within the Edwards Aquifer San Marcos Platform

A typical example of the electrical properties of the Georgetown Formation, the Person Formation, and the Kainer Formation, along with the associated mem­ bers, is shown in figure 12 with an electric log of well AY-68-28-910.

The electric log is probably the best correlation log for the Edwards

because of the high and low resistivity zones common to limestone. The gamma ray is a good supplemental log but is not as satisfactory as the electric log because the limestones generally have low radiation properties. In the unsat- urated part of the Edwards the gamma-ray log is usually the only log available for correlation.

The general pattern of the resistivity curve (on the electric log) is as follows: High resistivity in the Georgetown, top of the Person, middle Person, top of the Kainer (Grainstone member), and part of the lower Kainer (Dolomitic member). These high resistivities usually are separated by low to medium-low resistivities in the upper and lower Person, middle Kainer (Kirschberg evapo- Hte), lower Kainer (Dolomitic member), and basal Kainer (Basal nodular mem­ ber). The tops of these formations, or members, usually are picked where the resistivity curve shifts from high to low resistivity or vice versa.

Georgetown Formation

The resistivity curve in figure 12 shows a high resistivity of more than 1,200 ohmmeters in the lower Georgetown. The top of the Georgetown cannot be determined because of the effect of well casing on the resistivity log.

The SP curve for the top of the Georgetown is adversely affected by the well casing also. In the lower Georgetown, the SP curve gradually shifts to the left (negative).

The gamma-ray curve shows the Georgetown as three spiky peaks of 45 to 50 cps (fig. 7). The top is picked at the base of the series of high spiky peaks of 60-70 cps radiation of the Del Rio Clay.

Person Formation

The resistivity curve, mentioned in the discussion of the identification of the Georgetown (fig. 12), continues to the right to a peak of more than 2,000 ohmmeters, which marks the top of the Person. The resistivity curve shows the Person Formation as three peaks of about 1,600 to 2,000 ohmmeters and three suppressed zones of about 200 to 600 ohmmeters. The Regional dense mem­ ber, the basal unit of the Person, is within the lower 20 feet of the lower suppressed zone. The top of the Regional dense member is picked about 20 feet above the shift toward the high resistivity peak that marks the top of the underlying Kainer with the aid of other logs.

*. ithe SP curve in figure 12 is a flattened and distorted mirror image of the

resistivity curve. It deflects about 10 millivolts to the left (negative) oppo­ site the resistivity peak in the top of the Person Formation. It shifts back to positive opposite the broad zone of low resistivity in the upper Person and is unevenly negative opposite the zone of high resistivity in the middle Person. The curve generally is positive opposite the zone of low resistivity in the lower Person. The Regional dense member cannot be identified on this SP.

Electric logs for the freshwater part of the aquifer are not satisfactory for locating the Regional dense member. The Regional dense member is seldom manifested on either the resistivity curve or the SP curve with an identifiable deflection. It is more reliably located on- a suite of neutron, gamma-gamma, and caliper logs (fig. 13). These logs show the Regional dense member as a zone of low porosity and high density and also indicate that the borehole is about the same diameter as the drill bit (Maclay, Small, and Rettman, 1981). Downdip, and within the saline portion of the Edwards aquifer, Rose (1972) noted that the Regional dense member shows a distinct decrease in the SP curve, and the resistivity curve shows a corresponding peak at the same relative positi on.

The gamma-ray curve shows the Person Formation to have low gamma radiation of about 15 to 30 cps in the upper part (fig. 7). The top of the Person is picked where the curve shifts to the low 15 cps radiation from the spiky peak of about 45 cps in the Georgetown Formation. There is a zone of spiky peaks of 40-50 cps near the middle of the formation and a zone of spiky peaks of 40- 55 cps at the base of the formation that represents the Regional dense member. The top of the Regional dense member is picked where the curve shifts to the 45 cps radiation about 200 feet below the base of the Del Rio Clay.

Kalner Formation

The Kainer Formation is divided into four units, the Grainstone member, the Ki rschberg evaporite, the Dolomitic member, and the Basal nodular member. A discussion of the picks using electric logs (fig. 12) is given first and using other geophysical logs (figs. 7 and 13) is second.

As shown in figure 12, the top of the Grainstone member is picked where the resistivity curve shifts to the right, to a peak of 2,000 ohmmeters which is commonly about 200 feet below the base of the Del Rio. The Grainstone is shown as two high peaks of 1,600 to 2,000 ohmmeters resistivity separated by a recessive zone of about 1,000 ohmmeters resistivity. The top of the Kirschberg evaporite is picked about 50 feet below the top of the Grainstone member and at the base of the bottom peak. It is shown as a 50-foot zone of low resistivity of about 800 to 1,200 ohmmeters. The top of the Dolomitic member is picked at the top of a narrow peak of about 800 ohmmeters at the base of the Kirschberg. The curve is unevenly recessed for about the next 90 feet and the resistivities range from a low of about 200 ohmmeters in the upper middle part to about 800 ohmmeters near the bottom. The top of the Basal nodular member is picked at the base of a low peak of about 1,000 ohmmeters. The resistivity curve for the Basal nodular member is similar in shape and thickness to the resistivity curve for the Kirschberg evaporite. The Basal nodular member is about 60 feet thick and has an upper and lower zone of low resistivity of about 400 ohmmeters with a narrow peak of about 700 ohmmeters in the middle. The base of the Basal nod­ ular member, which is also the base of the Kainer Formation and of the Edwards Group,, is picked where the curve shifts to the left toward lower resistivity and becomes an erratic line of about 500 ohmmeters at the top of the Glen Rose Formation. The SP curve shows some response down through the top of the Ki rsch­ berg evaporite (about 480 feet). Below 480 feet, the SP gradually shifts to the right. This portion of the curve has no distinguishing features that are valuable for determining formation contacts. The SP curve deflects about 15 millivolts negative opposite the resistivity peak that indicates the position of the Grainstone member. The curve shifts to positive opposite the low resis­ tivity of the upper Kirschberg evaporite but below the Kirschberg, the SP curve Is insensitive to changes in lithology.

The top of the Kainer Formation (and the top of the Grainstone member) is picked at the base of the narrow spiky zone representing the Regional dense member (fig. 7) on the gamma-ray log. The base of the Grainstone member or the top of the Ki rschberg evaporite is arbitrarily picked about 70 feet below the top of the Grainstone member just above a zone of three narrow spiky peaks having radiation of about 45 cps. The Kirschberg is picked more reliably on the neutron log at the top of the high porosity zone and on the caliper log on the large increase in borehole diameter over the size of the bit (fig. 13).

-22-

The top of the Dolomitic member is picked about 40 feet below the top of the Kirschberg. The top of the Basal nodular member is picked at the top of a zone of a gradual increase of gamma radiation (fig. 7) which ranges from 50 to 80 cps. The member is about 270 feet below the top of the Kainer Formation. The neutron, gamma-gamma, and caliper logs (fig. 13) show the Basal nodular member to have low porosity and high density and to have a borehole approximately the same diameter as the drill bit. The base of the Kainer (and the base of the Basal nodular member) is picked where the gamma-ray curve (fig. 7) shifts to­ ward a lower gamma radiation of about 75 cps. The base of the Kainer is about 60 feet below the top of the Basal nodular member.

Devils River Trend

The only strati graphic unit in the Devils River Trend in the Edwards aqui­ fer is the Devils River Limestone. The resistivity curve of this unit shows the upper part of the Devils River generally to have very high resistivity (fig. 8). The top is picked where the curve shifts to the right toward the high resistivity at the base of the Del Rio Clay.

The resistivity curve of the Devils River Limestone shows medium high to high resistivity throughout the formation. A zone of high resistivity occurs near the middle of the formation and another zone of high resistivity occurs near the base of the formation. The base of the formation is picked where the curve shifts toward the left to low resistivity in the Glen Rose Formation.

The SP curve deflects left (negative) about 20 millivolts at the top of the Devils River and gradually decreases by 10 or 20 millivolts. The lower part of the SP curve is about -40 millivolts except near the lower part (base) of the formation where it shifts to the left to about -50 millivolts. The lowest part of the curve increases toward a higher SP at the base of the forma­ tion.

The gamma-ray curve in figure 9 shows the natural gamma radiation proper­ ties of the Devils River Limestone. The average radiation is low, generally between 20 and 30 cps. The top of the Devils River is picked where the curve deflects back to the left, from the high peaks of over 40 cps in the Del Rio Clay to lower radiation of about 25 cps. It increases in the basal part of the formation to about 40 cps. The curve of the formations above the Devils River show an apparently lower radiation because the signal is attenuated by casing.

Maverick Basin

Electric logs show distinctive patterns that are useful for determining stratigraphic correlations in the Maverick Basin. They usually show signifi­ cant changes in resistivity in the limestone and have more definition than the gamma-ray logs, which are excellent supplemental logs. The typical resistivity curve shows high resistivity for the Salmon Peak, higher resistivity for the McKnight, and medium high to medium low resistivity for the West Nueces. These high resistivities usually are separated from each other by zones of low resis­ tivity, and the formation contacts are picked at these changes.

-23-

Salmon Peak Formation

The resistivity curve in figure 10 shows the Salmon Peak Formation to have medium high resistivity of about 40-50 ohmmeters throughout the formation. The top is picked where the curve deflects to the right about 150 feet below the top of the Del Rio. The SP curve is without distinguishing characteristics except for a small negative deflection about 40 feet below the top of the Sal­ mon Peak.

The gamma-ray curve in figure 11 shows low gamma radiation of about 30-40 API gamma-ray units throughout most of the Salmon Peak Formation. The top of the Salmon Peak Formation is picked where the gamma-ray curve shifts to the left, to about 40 gamma-ray units, from the 70-80 units in the Del Rio. A nar­ row zone of slightly higher radiation of about 60-65 API gamma-ray units (Keys and MacCary, 1971) occurs about 130 feet below the top of the formation.

The sonic curve in figure 11 shows the Salmon Peak to have travel times of about 65-70 microseconds per foot in the upper half of the formation. Travel times in the lower half vary from 86 to about 65 microseconds per foot. The top of the formation cannot be picked on this log because it is shielded by the well casing.

McKnight Formation

The resistivity curve in figure 10 shows the McKnight as two peaks of more than 200 ohmmeters with a narrow zone of lower resistivity near the middle of the formation. The top of the McKnight Formation is picked where the resistiv­ ity curve deflects sharply to the right to a very high peak, which occurs about 500 feet below the top of the Salmon Peak.

The SP curve deflects about 25 millivolts to the left (negative) at the top of the McKnight. It drifts back to the right (positive) about 15 milli­ volts opposite the zone of low resistivity on the resistivity curve and then shifts back to the left about 10-15 millivolts in the lower part of the forma­ tion.

The gamma-ray curve in figure 11 shows the McKnight as a series of high spiky peaks of 80 to 100 API gamma-ray units. The top of the formation is picked at the start of the series of peaks.

The travel-time curve on the sonic log in figure 11 shows the McKnight as a broad zone of low travel time of about 50-55 microseconds per foot. This appears as a broad flat peak on the travel-time curve. There is a narrow zone of high travel time of about 75 microseconds per foot near the middle of the peak. The top of the McKnight is picked on the sonic log at the beginning of the peak where the travel times decrease from about 70 microseconds per foot to about 55 microseconds per foot.

West Nueces Formation

The West Nueces is shown as a series of unevenly elevated low peaks on the resistivity curve (fig. 10). The resistivity of these peaks decreases with

-24-

depth. The formation is separated from the high resistivity peak of the over­ lying McKnight by a decrease in resistivity, from about 200 ohmmeters to about 20 ohmeters, that appears on the curve as a sharp recession.

The top of the West Nueces Formation is picked at the low point in the sharp recession and is about 250 feet below the top of the McKnight. The base 1s picked at the end of a sharp recession and is about 250 feet below the top of the West Nueces Formation.

The SP curve of West Nueces Formation shifts left (negative) about 10 millivolts at the top of the formation and then drifts back in a positive dir­ ection. It is relatively featureless below a point about 80 feet below the top of the formation. The top of the Glen Rose is not apparent on this SP curve.

The gamma-ray curve in figure 11 shows the West Nueces to have about 50 API gamma-ray units radiation, which is about the same as the Salmon Peak. The top is picked about 180 feet below the top of the McKnight, at the base of the series of high spiky peaks. The base of the West Nueces, top of the Glen Rose, is not evident on this curve.

The sonic log shows a 50-foot zone of high travel time at the top of the West Nueces. Travel times in this zone are about 75 microseconds per foot. They decrease to about 58 microseconds per foot below this zone and remain about the same for the rest of the formation.

The top of the West Nueces is picked at the top of the 50-foot zone of high travel time. The base is picked about 230 feet below the top where the travel-time curve changes from a series of low peaks with little difference in travel time between peaks and troughs to a somewhat more erratic series of high spiky peaks with a large difference in travel times between peak and trough.

Underlying the Edwards Aquifer

*the unit below the Edwards is the Glen Rose Formation. The top of the Glen Rose is picked on most resistivity curves at the point where the curve shifts from the generally higher resistivities of the Edwards to the lower resistivities of the Glen Rose (figs. 8, 10, and 12).

The top of the Glen Rose is picked on SP curves where the curve deflects to the right (positive) after coming out of the Edwards. The SP curves in the San Marcos Platform area commonly show this shift, but the SP curves in the Devils River Trend and the Maverick Basin frequently do not. The SP curves generally are unsatisfactory for picking the top of the Glen Rose.

In the San Marcos area, the gamma-ray curve usually shows a slight decrease 1n radiation from the higher radiation of the rocks near the base of the Edwards to lower radiation in the upper Glen Rose. However, in the western part of the area there is no noticeable change in radiation shown on the gamma-ray curve near the part representing the basal Edwards and upper Glen Rose.

-25-

Few sonic logs were available for study of the Edwards-Glen Rose contact. Those that were available show a change in travel time at the top of the Glen Rose and are satisfactory for determining the top of the Glen Rose.
