SHALE DOME EXPLORATION IN THE GULF COAST

Paul S. Freeman Consulting Geologist

Diapiric shale masses are formed along certain trends during favorable geologic times, mainly by the geologic process known as "sedimentary volcanism". A thorough understanding of this p r o c e s s i s the key to interpreting the origin and growth of dia- pir ic shale masses and their tremendous hydrocarbon reserves and potential i n the Gu l f Coast.

Diapiric shales produce negative gravity a n o ma I i es because of low densities. Density logs show densities to be a I mos t as low as salt. Low velocities (indicated by sonic logs) cause shale-mass structures to be ma p p e d seismically as "lows" instead of "highs", unless correct velocity functions are used.

Explorationists must note the similarities and emphasize the differences between shale-dome and salt-dome exploration. Although intrusive shale plugs exhibit the same p r o n ou n c e d structures as salt plugs, buried extrusive shale masses are generally not associated with pronounced r a d i a I faulting, sharply upturned beds or other commonly recognized structural attributes of intrusive masses.

A common clue to subsurface diapiric masses i s half-ohm r es i st i v i t y (IES log) caused mainly by high water c o n t e n t of the shale. Few correlations, i f any, can be. made within the diapiric mass. An a b n o rma I microfaunal sequence i s nearly always encountered, as i s high pressure shale gas. Because of their greater m a g n i t u d e and distinguishable direction, mudflow dips within an extrusive mass can often be recognized by a dipmeter survey. Dips recorded within an intrusive s h a l e plug or a "shale sheath" should be random i n both magnitude and direction. S i d e w a I I cores within a diapiric mass reveal churned shale pellets and gas bubbles i n the shale units; and dis- rupted sand-grain frameworks i n the sandstones.

Sandy, water-fi lled, gas-churned mudflows are high porosity, low permeability masses that serve as barriers to hydrocarbon migration. Intrusive structures have had a timely injection in order to trap migrating hydrocarbons whereas extrusive shale masses are unique barriers because the barrier i s present before or during d e p o s i t i o n of the adjacent beds.

Shale structures and associated hydrocarbon traps are illustrated by seven fields i n the Louisiana and Texas Gulf Coast.

BIOGRAPHICAL SKETCH - Paul S. Freeman

Paul S. Freeman is a native of Pharr, Texas i n the Lower Rio Gmnde V a I l e y . He attended the U.S. Mi l i ta ry Academy a t West Point and the University of Texas at Austin. After receiving a B.A. i n Moth (1959) and a B.S. i n Geology (1960), he was employed in Mexico on a mercury exploration program by P. G. Lake, Inc. He l a t e r s e r v e d o n active duty with the Corps of Engineers and returned tograduate school at the University o f Texas where he received the M.A. degree i n Geology.

He was employed as an exploration geologist with Union Oil of California both in Houston and New 0 r l e a ns from 1963 to 1967. He returned to Houston i n 1967 with T e x a s Oil and Gas Corp. and since 1969 has been a consulting geologist here.

EDITOR'S NOTE TO ALL MEMBERS

The Bulletin i s the Society's greatest operational expense. Last year the printing and postage costs were almost $9,000 (which was offset by a $2,000 contribution from AAPG for the Special Convention Issue).

The new format and reduced bulk o f the Bulletin are designed to reduce its cost. To effect further savings, the moiling list w i l l be rigorously culled after the dues dead- line - November 15th. Thereafter, ALL MAILOUTS WILL END to those members whose dues are delinquent.

In 1969, he was consulted on the effects of radiation damage in I u na r dust as a possible hazard for l u n a r surface operations. He was involved in planning and safety e v a I u a t i o n for b o t h the Apollo 11 and 12 missions. Doctor Zeller i s the author of numerous papers.

Through the e f f o r t s of N.A.S.A. and the Russian Space p r o g r a m s , we have greatly increased our knowledge of the surfaces of our immediate neighbors in the solar system. Photographs of the surfaces of the moon and Mars w i l l be shown together with similar and contrasting photos of earth surface features. In addition, a summary of the seismic measurements and the lunar rock analysis data from the Apol lo program wi l l be presented to provide an overview of the similarities and contrasts between the earth B the moon .

Radar imaging studies conducted by United States investigators and the excellent information provided by the Russian soft landing has permitted us a limited look at the surface beneath the dense and cloudy atmosphere of Venus. Even this restricted view makes i t poss i b l e to reach a number of interesting c o n c l us i o n s about the planet. Mercury has n o t been visited by spa c e c r a f t , but radar and optical telescopes have furnished information about the rotational properties as well as some indication of its surface characteristics.

By means of a review of the available data, a basis i s provided from which geologic comparisons can be made among the inner planets.

2:30 P.M. to 6:00 P.M. with a Short Coffee Break

PROSPECT ANALYSIS and EVALUATION OF UNDRILLED ACREAGE

Presented by Mr. J. J. Arps, a Petroleum Consultant of Dallas, Texas

If you plan to attend, please sign 8 return the attached card, prior to November 15th. This w i l l a I l o w us to make arrangements for handouts, refreshments, etc. The

fee for the series i s $10.00 per person, with registration and payment to be m d e a t the auditorium before the first session. First day registration begins at 2:00 P.M. There w i l l be problems to work, so bring pencils and erasers.

In 1969-70 Mr. Frank W. Cole, a consulting petroleum engineer, presented a well-received seminar on Petroleum E n g i n e e r i n g . He presented the fundamental

. characteristics of reservoirs, so that one could distinguish between the productive, the marginal, and the non-productive "trap". Mr. Arps w i l l bui ld on this foundation and

carry us into the discipline of assigning economics to d i f f e r e n t types of hydrocarbon traps. He has several wles of thumb that bring order to this complex f ield. He presents

forms for

a) Profitability analysis o f a prospect

b) Appraisal of underdeveloped acreage in the prospect

Today, when the price of domestic o i l and gas i s changing r a p i d I y i n response to the increasing costs o f establishing new reserves, the economically undrillable prospects of one month, six months, or a year ago must be continually re-evaluated. This can be a very complex procedure for the unoriented, but with the proper shortcuts, training, and experience, most of the mystique and complexity can be r e m o v e d from the economic evaluation process. I t i s to p r o v i d e us with this training and exposure that Mr. Arps has been asked to present his petroleum economics course.

H. G.S. PUBLICATION REVIEW

ABNORMAL SUBSURFACE PRESSURE: A Study Group Report 1969-1971.

Edited by James A. Ragsdale. Published by H o u s t o n Geological Society, 234 Esperson Building, Houston, Texas 77002, in 84x1 1-inch p a p e r b a c k form. 92 pp. $5.00 plus 2 5 ~ Texas sales tax plus applicable postage. Weight 13 ounces.

This i s a c o m p r e h e n s i v e five-part study of subsurface pressure p h e n o m ena . I t concludes wi th a case history o f Midland Field, Acadia Parish, La., and about 400 references pertinent to geological, geophysical, chemica I, mineralogical B engineer-

ing aspects of the book's subject. M u c h o f the book i s d e v e l o p e d from U.S. Gu l f Coast experience, but applies also to virtual ly a l l Tertiary-Mesozoic basins.

In t h e first part, origins o f abnormal pressures are d e s c r i b e d i n terms of f luid pressure and hydrostatic environments, compaction, vertical and horizontal compres- sion, uplift, f luid density contrasts, recharge, faulting, absorption, osmosis, mineral- ogy and petrography, and geothermal effects. Detection techniques (before and during dril l ing, and from subsequent borehole measurements) are described brief ly.

The second part i s entitled "Definition, Identification, and M e a s u r e m e n t of F\J o r mu I and Abnormal Subsurface Pressures." Explorationists can correlate abnormal

pressures to hydrocarbon production type and hence to well economics. Knowledge of pressure environment i s vi tal to effect safe, efficient dri l l ing. Normal and abnormal

pressures a r e defined in terms of h y d r o s t a t i c and overburden pressures and pressure gradients, and equivalent mud weights. Direct and indirect methods of measuring subsurface pressures are described. Illustrations i n c l u d e plots of shale resistivity, shale travel time and induction conductivity vs. depth, comparison of density log vs. logged shale cuttings, pulsed neutron log, and salinity plots.

The third part i s entitled "The Geophysical Aspects of Abnormal Fluid Pressures". Seismic common-depth-point data provide plots of interval velocity vs. depth, grossly approximating velocity s u r v e y s of integrated acoustic logs. In a sand-shale section, undercompacted and overpressured s t r a t a may be generally indicated by velocity de- partures that are lower than the normal trend. Bouguer gravity anomalies often express this density c o n t r a s t qualitatively, but they must be corroborated by other methods. Integration of geophysical, dr i l l ing and geological data can aid efficient, safe dri l l ing of o v e r p r e s s u r e d zones. Examples of seismic velocity analyses from two offshore Louisiana areas are included among the fourteen illustrations. Reliability of geophysical methods of predicting overpressure i s evaluated. Sources of error in velocity analyses are discussed -- dipping beds, faulting, multiple reflections, anisotropy, surface weathering, water depths, lithologic changes, etc.

Midland i s a major f ield on a faulted structure i n the Anahuac-Frio trend. Most

of its gas i s in overpressured reservoirs. Fluid environments suggested by pressure data are cri t ical to entrapment. H y d r o d y n a m i c flow indicated by pressure data caused numerous anomalous f luid contacts. Some secondary migration i s indicated by pressure

and permeability configurations. Spill point phenomena affected hydrocarbon accumu- lation. Some inferred geophysical interpretation o f Midland f ield i s included.

In summary, this book describes the state-of-the-art as of p u b I i c a t i o n time.

Strong efforts are underway to increase knowledge of subsurface pressures. The exhaus- t ive bibliography alone would make t l ~ i s book worthwhile.

The book i s of o b v i o u s value to earth scientists and engineers. I t can also a id

regulatory agencies i n prescriptior o i realistic safety regulations. Emphasis

i s on the multitude of methods being applied to pressure p r o b l e ms as cross-checks on one another, & the certainty of further important future progress in related technology

and f ield applications.

MEMORIAL

WILLIAM ROBERT LEDBETTER (1921-1971)

William (Bill) Robert Ledbetter passed away August 12, 1971, at the Methodist Hospital i n Houston, Texas, after a sixteen month struggle with acute leukemia. He was born March 12, 1921, in Beaumont, Texas, the son of a prominent Beaumont doctor. B i l l attended Ogden and David Crockett Grade Schools and B ea u m o n t High School, where he graduated in 1938. He was attending Texas A & M College in 1939, when his studies were interrupted by World War 11.

B i l l wasamos tded i ca ted and p a t r i o t i c man toGodandhiscountry. Asa Lieutenant in the U. S. Army, he served under Major General Withers Burress with the 100th Field Artillery Division in the E u r o pea n Theatre. He was wounded during the Battle of the Bitche Fortress in France on December 17, 1944, requiring hospitalization for a period of sixteen months in England, McCloskey General in Temple, Texas, & in the P e r c y Jones Hospital in Battle Creek, Michigan. He was subjected to five major operations on his paralyzed right arm to restore severed nerves & other complications. For his heroic feats on the battlefield, B i l l was decorated with the Bronzestar for valor and the Purple Heart. Due to his love for the army and his country, he r e t u r n e d to active duty in Morch of 1946 at Fort Bragg, North Carolina, and in January of 1947 he 9 l ec t e d to become a reserve officer, with the rank of Captain and later Mojor. He returned to Texas A 8 M to receive his B.S. degree in Geology in 1948, second in his geological class.

B i l l had one very worthy c o n so l a t i o n by being wounded in battle. He met a vivacious b r u n e t t e nurse in the McClosky G e n e r a I Hospital by the name of Mikki Kossey, resulting in marriage shortly thereafter. Out of this union of love, a son and

daughter were born. Ronnie i s married and has comp I e t e d five years of active duty with the U.S. Navy. He i s following i n his father's footsteps by attending Texas A&M where he i s majoring in electrical engineering. Gayle, recently married, completed her B.S. and R.N. degrees, with honors, in nursing from Texas Christian University . She i s currently with her husband at Keflavik, Iceland, at the U. S. Weather Station.

B i l l joined Texaco, Inc. June 15, 1948, and quickly became one of the main- stays of the Houston Division's Geologica l Department. Being a company man through- out his geologic c a r e e r , his significant contributions to the success of this company's exploration, development, and recruiting activities are well documented in Texaco's files. These talents were r e c og n i z e d early by Texoco and he was quickly moved to positions of higher responsibility. From Trainee in Houston, he was transferred to San Antonio July 8, 1948, as a Geologist. On November 1, 1949, he was transferred to the Corpus Christi District and was promoted to District Geologist of the Tyler District September 20, 1951, and the Corpus Christi District S e p t e m b e r 1, 1955. B i l l was elected President of the Corpus Christi Geological Society for the year 1959 and was extremely active in developing successful programs for i t and the Gulf Coast Associa- tion of Geological Societies. On October 1, 1960, B i l l was promoted to the Division Staff at Houston and served there as Assistant and Assistant to the Division Geologist.

He was a member of The American Association of Petroleum Geologists and the Houston

Geological Society.

During his illness, B i l l gave medical science his fu l l cooperation and never re- fused new experiments and treatments by experienced and y o u n g doctors a l i ke so that some day someone who may never have known B i l l could be healed through his contributions to science. He was loved even by his doctors and nurses. The most brave and loving of a l l at his bedside at a l l times was his wonderful devoted wife, M ikk i . Through

advances in medical science, B i l l and Mikk i were able to celebrate their 25th wedding anniversary, see their first grandson, attend the college graduation ceremonies o f their

daughter, and al low B i l l to proudly give his daughter in marriage. Contributions have been received in memory of Wil l iam R. Ledbetter by the Special H e ma tology Depart-

ment, Baylor College of Medicine, Pines presbyterian Church, and the Texas A & M Memoria I Fund.

A diplomatic apprcach, a command of the English language, an inquisitive mind,

and a sharp and witty s e n s e of humor made Bi l l a welcomed and contributing member of any group. He was an Elder in the Pines presbyterian Church, where many times he

assisted Dr. R. Sunday i n worship services. He was also C h a i r m a n of the Boo r d o f Deacons at the Parkway Presbyterian Church in Corpus Christi, Texas. He and Mikk i were also dedicated to helping the younger g e n e r a t i o n by teaching the high school

youth groups a t church, where they sponsored the youth f e I l o w s h i p group. He was a c t i v e in the Boy Scout mo v e me n t , serving as a Scout Master, and with the Texas A & M Alumni Association.

B i l l ' s love for others can be questioned no more than the love others had for him. His religious convictions were deep and firm, being I o d g e d in faith and quiet under-

standing, and served as a great s t r e n g t h to him and others during his illness. Never

d e r o g a t o r y , but always receptive, he r e c e i v e d respect and was honored from a l l quarters.

We, who have been privileged to know B i l l , hove b e e n enriched wi th his vast knowledge, love, and unselfish contributions to his fellow man. B i l l w i l l best be remembered by his innumerable friends for his stature as a man and his wonderful sense o f humor even under adverse conditions.
