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.

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.
