HIGH ISLAND AREA

0CS-G-73O4

Amerada Hess Corporation proposes to dr i l l two (2) exploratory wells

on the .,bject le.se. 0CS-G-73O4. for the purpose of evaluating the

potential of the lease to produce cohere lai quantities of oi l and

gas. The exploratory work Is to be done with a Jack-up type Mobile

dril l ing r ig. The drilling prog™ 1s expected to co*aence during

Oune. 1985 and may extend through September, ig85 and will be

sustained by onshore support facil it ies located on Pelican Island,

near Galveston, Texas.

Attached as Exhibit No. I 1s a vicinity map depicting the location of

High Island Block A-123 and Its proximity to the Texas Coastline.

In January. 1985 subsequent to acquis i t ion of th i s lease on High

island Block A-123, Amerada Hess Corporation contracted Intersea

Research to conduct a I t i -sensor survey over the block to gather

information on potent ia l shallow d r i l l i n g hazards and to locate

magnetic anomalies, and to evaluate possible c u l t u r a l resources. The

surveys taken u t i l i zed the fo l lowing instrumentat ion:

1.0 IDS Navigation System.

2.0 Simrad EA ?00 Fathometer. 38 kHz. 7 deg. beam wid th .

3.0 O.R.E. Subbottom P r o f i l e r , 3.5 kHz, O.R.E. 140

transceiver.

4 .0 Hamco Watergun, 200 cu. 1n. , 2000 p s i , DFS-III

12 channel rece iver , d i g i t a l near t r ace .

5.0 Klein M-401 Side Scan Sonar, 656 f t /channel sweep r a t e ,

3-6 f t reso lu t ion .

6.0 Geometries Proton Precision Magnetometer.

7.0 Teledyne 40- t ip Minisparker, s ingle channel streamer.

The conclusion and recommendations of th i s survey are summarized as

f o i l ows :

A. SHALLOW GEOLOGIC CONDITIONS:

1 . Three generations of paleochanneling were Iden t i f i ed

within the survey area. Extensive wave plan erosion has

eliminated a l l but the deepest port ions of th i s

paleochannel system.

2 . No evidence of shallow f a u l t i n g was observed 1n the

survey area.

3 . Several shallow a n t i c l i n a l s t ructures were i d e n t i f i e d .

There is a p o b b i s i l i t y for overpressured gases or f l u i d s

wi th in these st ructures at approxiximately 2100 f t below

sea leve l . Evaluation of the survey track data adjacent

to each of the propoosed locations indicates no

unmanageable gas or other d r i l l i ng hazards present In the

area. However, d r i l l i ng operations w i l l be conducted so

as to be prepared for shallow gas cn this lease.

CULTURAL RESOURCES EVAI MATTnui.

X- Nc erosional bank or margin features of potential

archaeological significance were detected near the

channel systems or elsewhere In the block.

2. No magnetic anomalies were recorded.

3. No areas of potential cultural significance were detected

during the survey.

Interpretation cf the available seismic Information allowed the

generation of current structure maps. Exhibit No. 7 Is

1. DESCRIPTION OF PROPOSED ACTIONS

A. Amerada Hess Corporation proposes to In i t iate exploratory d r i l l i ng opera­

tions on High Island Bloek A-123. OCS-G-7304. during the second week In

June. 1985. These operations may extend through Septeafcer. 1985.

Transportation of material, supplies, and personnel between High Island

Block A-123 and Amerada Hess Corporation's onshore fac i l i t i es at Pelican

island. Texas, w i l l be by boat or helicopter. One crew boat and one

supply boat are prepared to service rhe r ig dal ly . The frequency of hel­

icopter f l i gh t s for transportation of d r i l l i ng personnel Is estimated at

one round t r i p a day. The travel distance between High Island Block A-

123 and Pelican Island Is 120 miles round-trip.

Interstate 45. the primary means of land transportation to Pelican Island

provides an adequate access to the Gulf of Mexico. Coominlty growth and

vehicular t r a f f i c Is not expected to Increase during the d r i l l i ng opera­

t ion; therefore, no additional f ac i l i t i es are required to conduct this

operation.

B. This exploration endeavor w i l l require approximately 80 d r i l l i ng person­

nel. For each seven day working schedule, one Coapany supervisor and 40

contract workers w i l l be required Tor the r ig operation.

There w i l l also be i onshore base dispatchers each working 12 hour tours

for a 24 hour day. One Conpany and 4 contract eaployees w i l l be respon­

sible for loading and transferring supplies from the Pelican Island to

the work boats. Work boats and 1n certain emergencies, helicopters w i l l

be used as the transferring agent to the r i g . The work boats w i l l

require a crew of 5 people changing out every 7 days.

C. There w i l l be no additional support f ac i l i t i es needed for the proposed

act iv i ty .

D. There 1s no requirement for the use of new or unusual technology in the

dr i l l ing of the proposed wells.

E. See Exhibit No. 1 for map showing the location of the proposed act iv i ty

In relation to Texas' Coastal Zones.

F. No plans of development/produc tion are in progress at this time.

2. DESCRIPTION OF THE AFFECTtU ENVIRONMENTS AND IMPACTS

PHYSICAL AND ENVIRONMENTAL

1. The proposed site of d r i l l i ng 1s located approximately 60 miles

southeast of Galveston, Texas in 100 feet of water and lies within

the boundaries of the white and brown shrimping grounds. Commercial

f ishing 1s done regularly around the year, quite often during the

peak shrimping months. However, High Island Block A-123 does not

He within the boundaries of any principal commercial fishing area

or high density recreational area. Fish near the shoreline w i l l not

be disturbed even though there may be a minimum increase of boat

ac t i v i t y due to r ig operation.

2. High Island Block A-123 is not a designated shipping area. Dr i l l ing

ac t i v i t y 1n this area w i l l have a minimal impact.

3. Water depths average 100 f t . and small recreational boats may occa­

sional ly appear 1n the area. However this d r i l l i ng operation should

not Interfere with any fishing or recreational ac t i v i t ies .

4. Seismic analysis indicates no magnetic anomalies. Side scan sonar

did not reveal any features that could be construed to be cultural

1n nature. Although High Island Block A-123 Hes within a zone of

possible Paleo-lndian s i tes, the probability that any such sites

exist on this block is very low.

There are no marine sanctuaries, wildlife refuges, or preserves 1n

the Immediate area of High Island Block A-123, and since the entire

coastline of Texas can be considered environmentally sensitive In

varying degrees, there 1s no benefit seen 1n listing the major bays

and state and federal wildlife refuges along the coast. Prudent

operations and 1f necessary, employment of the "Amerada Hess 011

Spill Contingency Plan" should minimize Imp t to the area.

There are no pipelines or cables that pass through High Island Block

A-123.

To the best of our knowledge, hydrocarbons are the only mineral

resources to be developed In this area.

Available Information indicates there has been no dumping of mate­

r ia ls on the lease 1n the past. However, the possibility exists

that materials left by previous lessees may 1n fact be present on

the ocean floor. All dri l l cuttings, drilling mud, sanitary waste

ko'Urr and cooling water dumped during this operation will te 1n

compliance with the requirements of U.S. Coast 6uard, EPA and XS

Order No. 7.

Five species of marine turtles occur 1n the Gulf of Mexico. These

are the Loggerhead, Green Sea Turtle, Kemps Ridley, Hawksbill, and

the Leatherback. All five of these turtles are on the endangered or

threatened rpecies 11st. Some of the marine mammals that could be

present in the Gulf of Mexico are the Sperm Whale, Black Right

Whale, Humpback Whale, Sei Whale, Fin Whale, a l l of these are also

on the endangered soecies l i s t . The Brown Pelican, also Included on

the endangered species 11st, is known to reside along the Texas Gulf

Coast. Although the above mentioned species are not commonly seen

in the immediate area, they could be affected by an o i l sp i l l 1f one

we.e to occur; however, they have not been documented as having been

di rect ly affected by sp i l l s in the past. The probability of an o i l

sp i l l from this operation 1s very small and would be covered by fast

response under the "Amerada Hess 011 Spi l l Contingency Plan."

10. The results of a i r qual i ty analysis as detailed 1n the Plan of

Exploration show that projected gaseous emissions from the proposed

operations f a l l a great deal below the emission exemptions levels as

derived from EPA Reports AP-42, June and August 1977 and w i l l have

negligible impact due to dispersion by winds.

SOCIO - ECONOMIC

1. The primary service f a c i l i t y for this operation is to be at Pelican

Island, Texas. Personnel and supplies to support the operation w i l l

be transported from this f a c i l i t y .

2. The d r i l l i ng r ig to be used 1s a jack-up mobile d r i l l i ng uni t . I t

1s expected to be on si te by June, 1985 and i f a l l wells included In

th is plan are d r i l l ed , the operation would extend into September,

1985.

I

3. As a general rule, a large drilling rig of the type to be used will

require about 80 persons offshore with onshore support of approx­

imately 20 persons. Since the facility 1s already established, and

the drill ing rig personnel do nut normally live In the affected

area, no adverse Impact on the community should occur. To the con­

trary, the operation shoulc ; eve a positive impart cn stabilizing

•"loyment and stimulating gene * 1 business.

4. The supplies of drilling equipment, energy, food, water and the like

are adequate and it 1s anticipated that this proposed activity will

have l i t t le effect on current levels of consumption. Therefore, no

significant economic or demographic adjustments are anticipated.

3. UNAVOIDABLE ADVERSE IMPACTS

A. Drill ing of the proposed exploratory well in High Island Block A-123 w i l l

result in the ?jiSvharge of d r i l l i ng mud and cuttings Into the waters of

the Gulf of Mexico. The discharge of d r i l l cuttings w i l l bury sessile

benthic organisms in local areas under the discharge. The disposal of

mud may result in a minor decrease of primary productivity due to the

mortality or functional Impairment of phytoplankton and algae In the a-ea

of high tu rb id i t y . A large o i l s p i l l could resu^ *n retarding product­

ivi ty of the phytoplankton communities, therefore . . • th» community

structure for an unknown period of time. Amerao • » 1 • : the nec­

essary monitoring and control methods to prevent c o n . u « . . - . . of the sea

1n accordance with OCS Order No. 7.

B. Air emissions from combustion of fuel in r ig engines, boat engines, and

helicopters can affect the a i r quality near the offshore platforms and

~near the onshore travel routes. In most cases, these emissions w i l l be

local in nature and w i l l be quickly dissipated by cl imatic conditions.

Highly vo la t i l e , low molecular weight hydrocarbons would be released Into

the atmosphere from a blowout with the release of natural gas and crude

o i l . These hydrocarbons would cause some air pol lut ion and degra­

dation. I f a blowout resulted in a f i r e , large amounts of particulate

carbon and oxides of carbon, along with smaller but unknown amounts of

sulfur oxides, volati le hydrocarbons and par t ia l ly oxidized compounds

would enter the a i r . Local air would be severely degraded for the dur­

ation of the f i r e . The extent of degradation 1s undeterminable but 1t Is

unlikely that 1t would be a signif icant affect on land resources.

'•Of.

C. The risk and outcome of these Impacts are just i f ied 1n that presently the

only alternative would be not to d r i l l at a l l . The need for new energy

reserves far outweighs the minimal environniental Impacts that could pos­

sibly occur.

The proposed activity wi l 1 be worried out and completed with the commitment

that:

1. The best available and safest technologies w i l l be ut i l ized through­

out the pro ject . This Includes meeting a l l applicable requirements

for equipment types, general rroject layout, safety systems, and

equipment and monitoring systems.

2. All operations w i l l be covered by Amerada Hess Corporation's Oil

Spill Contingency Plan, which was approved by Minerals Management

Service on October 25, 1983.

3. All applicable Federal, State and local requirements regarding air

emission and water quality and discharge for the proposed act iv i t ies

as well as any other permit conditions w i l l be complied wi th.
