RE SHALLOW HAZARD SURVEY - SHIP 3HCAL BLOCK 97 SURFACE LOCATIONS FOR WILDCAT WELLS
Surface Locations:
The surface locat ions l i s ted below are ones which are separate; a l l other locations come from one of these:
#A Location: 4,500* FSL and 6,050' FWL of Ship Shoal Block 97 #H Location: 3,000' FNL and 3,700' FWL of Ship Shoal Block 97 #L Location: 2,250' FNL and 2,000' FWL of Ship Shoal Block 97 #M Location: 3 100' FNL and 5,800' FWL of Shi? Shoal Block 97
Geophysical Data:
Multi-sensor high resolution geophysical survey by Intersea Research Corporation fo r Tenneco Oil Company.
1. Seafloor Hazards. There are no seafloor hazards noted near the surface locatlors o f wells #A, #H, #1 and #M. Al l magnetic anomalies are to the north and east of the »A locat ion. Wells #H, #L and *M are 1n the n o r t h * * * ' quarter of the block and do not have any magnetic anomalies w i th in 1,500' of any of the locations.
2. Shallow Sediment Hazards. Tlie surface locations He in an area clear of obvious amplitude anomalies. The closest one 1s to locat ion #M which 1s 200' west from an anomaly. Although shallow gas 1s noted on sub-bottom pro f i le r and sparker records, 1t 1s Hkely biogenic and low 1n pressure.
3. Archaeological Features:
The Cultural Resource Service's report Included wi th the shallow hazard survey s tates that no archaeological si tes or features are present on bloclc 97. There are numerous scattered magnetic anomalies located on the block to the no'th and east of the #A well locat ion. These are also scattered around the #H, #L and #M well locat ions.
Conclusion
The proposed surface locations are acceptable and considered safe to d r i l l .

(2) D18CKIPTI0II OF PROPOSED ACTIOII
(A) TRAVEL MODES AHD BOOTES
Tenneco Oil Coapany plana to conduce exploratory dri l l ing oa Ship
Shoal Block 97. Aa aany aa 13 walla aay ba raquirad to fully evaluate tha
potential of thia Block. Operations ara expected to begin during tha laat
hal f of 1984 and cc extend into 1986 if a l l walla ara dri l led. Onahore
support will be provided froa Fourchon, Louiaiana.
I t is estlaatad that a craw boat wi l l make a dally round trip eo tha
Block and a supply boat a round trip evei r othar day. Two round trips daily
ara l ikely for helicopters. Boat traff ic w i l l ba directly to tha Oulf and
the projert Block froa Fourchon. Helicopter t r a f f i c ia noraally by tha aost
direct route froa tha baaa to tha Block, weather and traff ic condlcions
paratttiag.
(B) SUPPORT BASE
Tha support base w i l l be the Tenneco fac i l i ty at Fourchon. Louisiana.
Thla baaa occuplea a 7.5 acre sice with 624 feat of water frontage. Fac i l i t i es
include water, dieael fuel , gasoline, lubricants, marine and industrial
cleaners, and a 65 ton crane and warehouse. These fac l l l t l ee ara considered
adequate to support the operations planned with no additional personnel or
expansion of physical f a c i l i t i e s .
(C) M1W RJFFOtT FACILITIES
Mo nev onshore support faci l i t ies such aa new land bases, ref ina r la a,
ridley turtle, hawksbill turtle, and leatherback turtle. Threatened epecles
Include the loggerhead and green sea turtlee. Of the whale species, the sperm
is perhaps the moss common ln the Gulf of Mexico and the blue whale tha
least common, with only two sightings of the latter having been reported.
The other three species of whales aay be considered uncommon in the Gulf*
although the humpback waa once hunted commercially in the central Gulf during
the 19th century (Schaldly, 1981). The leatherback ia believed to prefer the
deeper oceanic watara while the other uncles of turtles are considered to
be more coaatal in nature. Thus the leatherback la unlikely to appear ln
Block 97 dua to the shallowness of the water whereas the otner epecles of
turtles may be present here at one time or another. Whales are found moat
frequently ln tha deep watara ln tlie v ic ini ty of the continental lope and
are thus unlikely vlal tors to Block 97.
General over exploitation of both turtles and whales for food and other
produces has been the major cause of their decline. A few nations s t i l l harvest
5
whales and turtles are s t i l l taken in aany parta of tha world. Additionally,
turt laa are often k i l l ed when they become trapped in fishing nets and a»e
unable co surface for a i r . Their nesting grounds are often disturbed and
the eggs are sometimes harvested for food. New evidence indicates that turtlaa
• r e being killed by the Ingestion of plastic trash, that whan floating ln tha
water, appeara to resemble Jellyfish (a favorite turtle food).
Support vessel movements and dri l l ing activit ies may cause a limited
disturbance to any turtlaa or perhaps whales that might venture Into the
v i c in i ty . To date, no sc ient i f ic evidence haa been found that would Indicate
that this type of disturbance has been significant in the decline of turtle
and whale populations. No significant or permanent impacts are foremen to
endangered or threatened species aa a reault of the exploratory dri l l ing
planned for Block 97.
(4) UNAVOIDABLE ADVERSE IMPACTS
Gallaway (1981) completed an extensive review of petroleum related
ac t iv i t i e s in the Texas-Louisiana continental shelf region. Potential negative
impacts addressed by him ware discharge of d r i l l cuttings, dr i l l ing f luids,
o i l sp i l l s , and produced formation watera.
Dri l l cuttfe&e are small fragments of the formation cut by the d r i l l
b i t and discharged Into the water on a continuous basis during the dri l l ing
of each wall. The larger cuttings tend to move directly towards tha bottom,
and in shallow waters ara l ikely to accumulate on the aeafloor ln mounds
or piles. In greater water depths, or where wave and/or current action are
vigorous, the materials may be spread to tha extent that no mounds develop.
When a pile accumulates, any immobile benthic organisms trapped beneath lt
w i l l another. Over time, plants and animals w i l l colonize the mound and the
6
"
seafloor will return to a condition similar to that in exlatence before
d r i l l i n g began.
Large-scale discharge of dri l l ing mud occure on an average of 8-10
times during the dr i l l ing of each v a i l . Also, as the cuttings ara discharged,
soma mud v i l l be entrained on them and v i l l wash free as tha cuttinga dri f t
towards the bottom. The clay particles in tha dri l l ing fluid tend to flocculate
on contact vith salt water, and along with the finer d r i l l cuttings, form a
turbid plums downetrsaa from the d r i l l r i g . When a large-scale release
of mud occurs, thla plume may reach down-current for a distance of up to
3,200 feet before l t i s completely diluted. The toxicity of the cuttings
and the drilling mud components la very alight and there la l i t t l e Impact
on water quality. The primary effect ie a reduction of light penetration
which may reduce primary production by phytoplankton.
The briny water from the formation being exploited Is tha primary
affluent discharged from production platforms. Since the act ivi t ies planned
for Block 97 are for exploration, there is unlikely to be any discharge of
• a l t vater except during tha testing of each well. Any amounts released
at thla tine would ba amall in qi< ntlty and of limited duration in terms
of time. These watara have been shown to be slightly toxic within a few
yards of the point of discharge. No adverse impacts have been shown to
occur to the marine l i f e beyond thia zone in the open Gulf. Theee waters
• r e usually high in tha concentration of inorganic salta and have very low
concentrations of hydrocarbons and other organic compounds.
An area of seabottom of up to five acres wi l l be temporarily removed
from that available to fishermen using bottom travls during the dri l l ing of
each vei l . The aree removed ia ao amall in relation to the areas remaining
7
open, that no detectable Impacts to the shrimp or bottomfish catch is foraeen.
O i l sp i l l s are always a poaaibility, however, good industry safety practices
combined vith a strict adherence to applicable rules and regulations has
greetly reduced the chance a of a damaging a p i l l . In fact, dri l l ing and
production activities are now considered a minor source of the total
hydrocarbons found in the Culf waters. More o i l Is added to the Gulf from
the flow of the Mlaalsaippl River than from OCS o i l and gas operationa.
In summary, unavoidable adverse impacts are considered to be minor
and temporary. They w i l l be confined to the lame' I La dri l l ing area. Nc
major or permanent damage to the marine environment or to nan's use of lt
ln anticipated froa the exploratory dr i l l ing p] nned for Block 97.
