PROPOSED TYPE AND SEQUENCE OF EXPLORATION ACTIVITIES AND TIMETABLE

Section 2

BelNorth Petroleum Corporation proposes to d r i l l 2 wells on East Cameron Block 306 to evaluate the subject lease to determine the potential for future development.

Exploratory drilling of the first well 1s scheduled to begin approximately February 1, 1987, subject to approval of this Plan of Exploration and issuance of the required Permit to Drill.

Exploratory activity should be complete June, 1987.

It should be empnasized that this schedule is tentative in tne meaning of 30 CFR 250.34-1 (a). Additional exploratory drilling must be predicated upon the need to define structures and/or reservoir limits. The fabrication and installation of platforms, producing facilities and pipelines are contingent upon tne success of tnese wells. In addition to the drilling of wells, other activities which may be conducted under this plan would be the setting of caissons or a template over temporarily abandoned wells, a velocity survey In a wellbore and soil boring.

1. DESCRIPTION OF PROPOSED ACTION

Belnorth Petroleum Corporation plans to conduct exploration activit ies on

East Cameron Area Block 306 (OCS-G 7667).

As proposed, the Plan of Exploration for East Cameron Area Block 306

consists of dr i l l ing two (2) walls.

At this time, the planned commencement date for Well "A" and a l l associ ­

ated act iv i t ies 1n Block 306 1s on or about February 1. 1987.

(a) TRAVEL MODES. ROUTES AND FREQUENCY

Tha proposed exploration activity for federal lease OCS-G 7667 will

require the use of a jack-up rig to d r i l l the exploratory walls on East

Camaron Block 306. Tha r ig wil l be moved to East Camercn Block 306 from an

unknown location in the Gulf of Mexico.

In addition to the dr i l l ing r ig , service boats wil l be used to transport

equipment, material, personnel and supplies to the d r i l l s i tes . I t Is

estimated that the craw boat wil l make 3 trips par week and the supply boat

wil l make 5 tr ips per weak from support uases located 1n Cameron, Louisiana.

The proposed travel route for these vessels begins at Cameron, Louisiana. The

vassals wil l move to East Cameron Block 306 via the most direct route from

Cameron, Louisiana.

Helicopter f l ights to East Cameron Block 306 wi l l average 8 round trips

per week and wi l l originate from and return to C'uteron, Louisiana. The

helicopters wil l normally ta' • VUQ cr.s\- direct route of travel between the two

points when a i r t ra f f ic and wcati. T renditions permit.

(b) SUPPORT BASE

The proposed activities will utilize an existing support base at Cameron,

Louisiana. The base provides 24-hour service, a radio tower with phone patch,

dock space, office space, a parking lot, equipment and supply storage space,

drinking and d r i l l water, etc. These proposed exploration activities will

help to maintain this base at Its present levels of activity. No expansion of

the physical facilities or the creation of new jobs is expected to result from

the work planned in conjunction with Block 306.

(c) NEW SUPPORT FACILITIES

No new onshore support facilities such as new land bases, refineries,

storage facilities, pumping stations, boat docks, helicopter pads or fueling

facilities are likely to be required because of the activities planned for

Block 306. Any newly discovered deposits of hydrocarbons should help to

maintain onshore facilities and activities at or near their present levels

rather than result 1n some type of expansion.

(d) NEW TECHNIQUES OR UNUSUAL TECHNOLOGY

No new techniques or unusual technology will be required for this

operation.

(e) MAPS OF PROPOSED ACTIVITY

As shown by the attached Vicinity Plat, the proposed activity 1s located

approximately 90 miles from the Louisiana shore.

( f ) TRANSPORTATION OF OIL AND/OR GAS

I f producible hydrocarbons are found they are likely to be transported to

shore through connections with the pipelines already in place near Block 306

2. DESCRIPTION OF THE AFFECTED ENVIRONMENT

(a) PHYSICAL AND ENVIRONMENTAL

(1) Commercial Fishing

East Cameron Area Block 306 1s located approximately 90 miles from shore

where the water depth is 192-202 feet. Shrimp and menhaden are the primary

fishing resources found 1> this area.

The placement of a dri l l i n g r i g on Block 306 may remove a portion of the

seafloor and waters above from harvesting by commercial fisheries.

Additionally, the waters adjacent to the d r i l l sites may become temporarily

turbid due to d r i l l i n g operations. These op rations should have no

significant impact on commercial fisheries.

(2) Shipping

Block 306 1s d e a r of a l l fairways and anchorage areas. The d r i l l i n g

vessel and each of the marine vessels w i l l be equipped with a l l U.S. Coast

Guard required navigational safety aids.

(3) Recreation

The proposed activities, which are primarily confined to East Cameron

Area Block 306 are located approximately 90 miles south of the Louisiana

coastline. Along the Coastal waters of the Gulf of Mexico off Cameron Parish,

Louisiana are located coastal beaches and ports supporting pleasure boating

and sport fishing. To protect these recreational resources, Belnorth

Petroleum Corporation will comply with OCS Order No. 7 regards nollutlon

prevention and control, and has established an Oil Spill Contingency Plan

which was approved by the Minerals Managenent Service. There are no adverse

Impacts expected as a result of the proposed activities.

(4) Cultural Resources

East Cameron Area Block 306 lies outside the Cultural Resource Sensitivity

Demarcation Line (USDI, 1979, Visual 1) and, therefore, falls 1n an area where

cultural resources are not likely to he found. An archaeological survey was

not required for East Cameron Area Block 306. Belnorth Petroleum Corporation

agrees that i f any site, structure, or object of historical or archaeological

significance should be discovered during operations, the findings will be

Immediately re,.ed to the Supervisor iind every reasonable effort will be

made to preserve and protect the cultural resource from damage until the

ervisor has given direction as to Its preservation.

(5) Ecologically Sensitive Features

There are no known ecologically sensitive features located on East

Cameron Block 306. The closest sensitive features are located along the

coastal shores of Cameror. and kfermi'ilcn Parishes. Louisiana. Tha ••.nsit lve

features include the primary f i s h and she l l f i sh nursery ground*,, ent" tha

recreational beaches. With the exception to the minimal boat and hel icopter

t r a f f i c , a l l operations w i l l be res t r i c ted to East Cameron 81ock 306. The

proposed a c t i v i t y w i l l have no e f fec t on any ecological ly sensit ive features.

(6) Exist ing Pipelines and Cables

Block 306 - There are no pipel ine* traversing East Cameron Block 306.

There 1s no evidence of any cable being located on th i s block.

(7) Other Mineral Uses

The a c t i v i t i e s proposed fo r East Came.on Block 306 w i 1 ! nave no d i rec t or

ind i rec t Impact on other mineral uses.

(8) Ocean Dumping

Ocean dumping 1s prohibited in t h i s area.

(9) Endangered or Threatened Species

Belnorth Petroleum's proposed operations at East Cameron Block 306 are

located approximately 90 miles south of the Louisiana coastl ine o f f Camaron

and Vermilion Parishes. Louisiana. These coastal shores and upland areas are

the habitat of several endangered or threatened species. These species

Include the Arc t ic peregrL.e fa lcon, the red-cockaded woodpecker, the bald

eagle, 'ne American Alligator, the red waif, Kemp's ridley sea turtle and the

Br • can. These species may be affected by the development of coastal

lands and/or tha occurrence of oil spills which may affect the species

directly or through their food sources. Since th. proposed activities Include

no plans for the development of coastal lands, he Impact on endangered or

threatened spades 1s primarily based on the occurrence of oil spills.

On pages 111—5 through 111-72 of th- F«M1 Environmental Impact Statement

for OCS Sale No. 47 there 1s a discuss'ui >* the factors for escto*at1ng the

slgnl'1 e of oils spills and their impar The Impacts on various

endangered and threatened species will depend on th* nature of the spill,

•taJ**..' conditions, proximity of spill tc species, tolerance for oil of

species, and the response time and effective*' „ of the oil spill clean-up and

containment services. Given these variables, the Inpact on the various

endangered or threatened species will vary from 11 :tle or no effect to

serious.

Tha experience of o^l and gas exploration in the Gulf of Mexico Indicates

that there 1s a smell probability of occurrence of an oil spill. Tha Draft

Environmental Impact Statement (DEIS) for OCS Sale No. A-62 and 62 1nr> cates

on page 71 that the "aggregate 15 year spill rata 1s .0009 percent of the

total volume produced." Table 7, page 73, of the DEIS Indicated that there

have been only 30 Incidents of oil spills for this 15 year period. The

probability remains low because of the level o? technology used by the oil and

yas industry to Insure safe and responsible operations. Belnorth Petroleum,

as a prudent operator wnl take the necessary measures to reduce the

probability of d l spills. Belnorth Petroleum's proposed operations 1n East

Cameron 306 should pose no threat to any endangered or threatened species.

(1) Related New Employment

Not applicable at this time.

3. UNAVOIDABLE ADVERSE IMPACTS

The proposed drilling activity 1n East Cameron Block 306 will result In

the discharge of Grilling mud and cuttings Into the waters of the Gulf.. The

discharge of d r i l l cuttings will bury sessile benthic organisms in local areas

under the discharge. The disposal of mud may result ina minor decrease 1n

primary productivity due to the mortality or functional impairment of

phytoplankton and algae 1n areas of high turbidity, t- ~ v*1 spill is very

unlikely but could result in localized severe mortal* * ?r

selective and functional impairment of of phytoplankt* * •:• '•• -eby

altering the community structure for an unknown period ui impacts

are considered temporary and minor.

Air emissions from combustion of diesel fue1 1n rig engines, boat engines

and helicopters can effect the air quality near the mobile offshore jackup

drilling rig and near the onshore travel routes. In most cases, these

emissions will be local in nature and will be quickly dissipated by climatic

conditions. Highly volatile, low molecular weight hydrocarbons would be

released Into the atmosphere from a blowout with release of natural gas.

These hydrocarbons would undergo some unknown degree of degradation, possibly

resulting in photochemical smog. If a blowout resulted 1n a fire, large

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

unknown amounts of sulphur oxides, volatile hydrocarbons and partially

oxidized compounds would enter the air. Local air would be severely degraded

for the duration of tha fire. The extent of degradation 1s Indeterminate, but

it 1s unlikely that it would be high enough to affect land resources or human

health.

These exploratory activities ara not expected to harmfully affect water

quality or interfere with commercial fishing operations, recreational

activities or shipping traffic.

SUMMARY

The proposed activity will be carried out and completed with the guarantee of

the following items:

1. he best available and safest technologies will be utilized

throughout the project. This Includes meeting all applicable

requirements for equipment types, general project layout, safety

systems, and equipment and monitoring systems.

2. All operations will be covered by a Minerals Management Service

approved 011 Spill Contingency Plan.

3. All applicable federal, scate and local requirements regarding air

emission, and water quality and discharge for the proposed

activities, as well as any other permit conditions will be *- ,.npl1ed

with.
