In i t i a l Development Operations and Coordination Document

Dear Nr. Bourgeois: In accordance with 30 CFR 250.34 et seq. and Notice to Lessees and Operators No. 84-01, Amerada Hess Corporation hereby submits for your approval the Development Operations and Coordination Document (DOCD) for South Timbalier Block 205 and Block 206 area, OCS-G 5612 and OCS-G 5613.

Enclosed are five (5) copies of the subject DOCD for confidential use and four (4) copies for public information. Because the development location 1s located off the coas* of Louisiana, an Environmental Report and Coastal Zone Management Plan Consistency Certifioation is required and enclosed.

Should the Minerals Managements. Service require any additional information, please do not hesitate to contact me at (713) 951-5680.

IN ACCORDANCE WITH 30 CFR 250.34 ET SEQ. AND NOTICE TO LESSEES AND OPERATORS NO. 84-01, AMERADA HESS CORPORATION HEREBY SUBMITS THE FOLLOWING INFORMATION FOR THE PLANNED DEVELOPMENT AND PRODUCTION.

A. DESCRIPTION

AMERADA HESS PROPOSES TO DEVELOP SOUTH TIMBALIER BLOCKS 205 AND 206 CONCURRENTLY. FIELD DEVELOPMENT MILL START WITH THE DRILLING OF WELL NO. 3 FROM THE EXISTING TEMPLATE ON BLOCK 205 ATTEMPTING TO PROVE UP ADDITIONAL RESERVES. DETAILED DESIGN, FABRICATION AND INSTALLATION OF PLATFORMS, PRODUCTION FACILITIES AND PIPELINES WOULD THEN BE COMPLETED AND PRODUCTION INITIATED.

THE PLATFORM FOR BLOCK 205 WILL BE A FOUR PILE, UNMANNED FACILITY SET NEXT TO THE EXISTING NINE SLOT TEMPLATE CAPABLE OF PRODUCING 50 MMCFD OF GAS. WELLS NO. 1, 2, AND 3 WILL BE TIED-BACK TO THE PLATFORM AND COMPLETED FOR PRODUCTION USING A CANTILEVER TYPE JACK UP DRILLING PIG.

THE BLOCK 206 PLATFORM WILL BE A 24 SLOT, 8 PILE MANNED STRUCTURE SET OVER THE EXISTING TEMPLATE CAPABLE OF PRODUCING 150 MMCFD. A PLATFORM DRILLING RIG WOULD THEN BE MOVED ONTO THE PLATFORM. WELLS NO. 1 AND 3 WILL BE TIED-BACK TO THE PLATFORM AND COMPLETED FOR PRODUCTION. WELL NO. 2 WILL BE SIDETRACKED, TIED-BACK TO THE PLATFORM AND COMPLETED IN SANDS PREVIOUSLY LOGGED. SIX ADDITIONAL NEW WELLS WILL BE DRILLED TO OPTIMIZE RESERVOIR DEPLETION. SIMULTANEOUS DRILLING AND PRODUCTION WILL TAKE PLACE DURING THE TWO YEAR DEVELOPMENT DRILLING PROGRAM.

PRODUCT TRANSPORTATION WILL USE SUBSEA PIPELINES TO THE NEAREST SHORELINE SYSTEM TAKE POINT THAT RESULTS IN THE BEST OVERALL ECONOMICS. NO NEW NEARSHORE OR ONSHORE PIPELINES OR FACILITIES WILL BE CONSTRUCTED. THE SPECIFIC SYSTEM WILL BE DETERMINED DURING THE NEGOTIATION OF THE GAS MARKETING CONTRACT WHICH IS EXPECTED TO TAKE PLACE DURING THE FIRST HALF OF 1989.

B. SCHEDULE

THE ANTICIPATED SCHEDULE IS PRESENTED BELOW. THE TOTAL TIME TO COMPLETE THIS PROJECT IS ESTIMATED TO BE 21 MONTHS TO INITIAL PRODUCTION WITH AN ADDITIONAL 24 MONTHS TO COMPLETE THE DEVELOPMENT DRILLING PROGRAM.

GEOLOGICAL, GEOPHYSICAL AND CULTURAL RESOURCE

1. SHALLOW HAZARD ANALYSIS

A SITE SPECIFIC SHALLOW HAZARD ANALYSIS WAS COMPLETED AND SUBMITTED AS PART OF THE PLAN OF EXPLORATION. THE WELLS PREVIOUSLY DRILLED AT THESE LOCATIONS VERIFY NO SHALLOW GAC HAZARDS EXIST. SOIL BORINGS WILL BE TAKEN AT THE PROPOSED DEVELOPMENT LOCATIONS TO PROPERLY DESIGN AND SIZE THE PRODUCTION PLATFORMS.

2. SITE SPECIFIC CULTURAL RESOURCE ASSESSMENT

NO IMPACT TO ANY HISTORICAL OR ARCHAEOLOGICAL CULTURAL RESOURCES IS EXPECTED FROM THIS DEVELOPMENT AS IT IS OUTSIDE THE AREA WHERE SIGNIFICANT CULTURAL RESOURCES WOULD BE FOUND. THE HIGH RESOLUTION GEOPHYSICAL SURVEY CONDUCTED ON 8L0CKS 205 AND 206 INDICATED SEVERAL SMALL MAGNETIC ANOMALIES THAT PROBABLY REPRESENT FERROMAGNETIC DEBRIS.

1. CONTINGENCY PLAN REFERENCE

AMERADA HESS' GULF OF MEXICO OPERATIONS AR COVERED BY THE APPROVED AMERADA HESS OIL SPILL CONTINGENCY PLAN. AS A MEMBER COMPANY, AMERADA HESS COULD CALL UPON CLEAN GULF ASSOCIATES FOR ASSISTANCE Itf A MAJOR SPILL INCIDENT SHOULD IT BE NECESSARY.

2. EQUIPMENT BASE OF OPERATIONS AND DEPLOYMENT TIME

CLEAN GULF ASSOCIATES' CLEANUP EQUIPMENT WOULD BE DEPLOYED FROM GRAND ISLE, LOUISIANA WITH BACK-UP FROM HOUMA OR VENICE, LOUISIANA. RESPONSE TINE FROM GRAND ISLE TO THE DEVELOPMENT LOCATION WOULD BE

4

ABOUT 9-11 HOURS (INCLUDING RIG UP). THE BACK-UP LOCATIONS WOULD TAKE AN ADDITIONAL I TO 3 HOURS.

F. OTHER

1. WATER DEPTH

THE WATER DEPTH AT EACH DEVELOPMENT LOCATION IS AS FOLLOWS:

(A) BLOCK 205 - 161 FEET

(B) BLOCK 206 - \V> FEET

2. DESCRIPTION OF DRILLING RIG AND POLLUTION PREVENTION EQUIPMENT

A TYPICAL CAN"! I LEVER JACK-UP TYPE RIG WILL BE USED TO COMPLETE THE WELLS ON BLOCK 205. THE BLOCK 206 PLATFORM WILL USE A PLATFORM DRILLING RIG. DECK DRAINAGE FROM BOTH PLATFORMS WILL FLOW INTO A SUMP BEFORE DISCHARGE INTO THE SEA. SANITARY AND PRODUCED WASTEWATER, DRILLING FLUID, AND DRILL CUTTINGS PROCESS AND TREATMENT SYSTEMS WILL BE OPERATED IN ACCORDANCE WITH APPLICABLE RULES AND REGULATIONS. SORBENT PADS WILL BE KEPT ON EACH PLATFORM TO WIPE UP SMALL DRIPS AND SPILLS OF PETROLEUM PRODUCTS AND DAILY VISUAL INSPECTIONS FOR ANY SOURCES OF POLLUTION WILL BE DONE.

• DRILLING THE BLOCK 205 (225) WELL NO. 3 AT RATE OF 200 7DAY TO A TVD OF 11,400 FEET.

• PLATFORM INSTALLATION REQUIRES TWO 7000 HP TUGS OPERAT'NG AT 70X CAPACITY, TWO HELICOPTER LTO CYCLES/DAY, AND THE CRANE BARGE HAS FIVE 2700 HP ENGINES OPERATING AT 50% CAPACITY.

• DRILLING RIG EMISSIONS FOR TIEBACK AND COMPLETION OF WELLS AND DEVELOPMENT DRILLING ARE ESTIMATED TO BE THE SAME AS FOR DRILLING 200 FEET OF HOLE ON A DAILY BASIS.

• PRODUCTION EMISSIONS FOR BLOCK 206 ARE BASED ON THE BURNING OF 1 MMSCF/DAY OF NATURAL GAS FOR POWER GENERATION, ONE HELICOPTER LTO CYCLE/DAY, AND A 3500 HP SUPPLY VESSEL OPERATING 48 HOURS/WEEK AT 70* CAPACITY. PRODUCTION EMI SIONS FOR BLOCK 205 ARE BASED ON ONE HELICOPTER LTO CYCLE/DAY AND A 30 KW GENERATOR OPERAT IN6 AT EIGHT HOURS/DAY. ALL OTHER EMISSIONS ARE CON DERED NEGLIGIBLE.

• PLATFORM INSTALLATION REQUIRES TWO 7000 HP TUGS OPERATING AT 701 CAPACITY, TWO HELICOPTER LTO CYCLES/DAY, AND THE CRANE BARGE HAS FIVE 2700 HP ENGINES OPERATING AT 501 CAPACITY.

• DRILLING RIG EMISSIONS FOR TIEBACK AND COMPLETION OF WELLS AND DEVELOPMENT DRILLING ARE ESTIMATED TO BE THE SAME AS FOR DRILLING 200 FEET OF HOLE ON A DAILY BASIS.

• PRODUCTION EM SIONS FOR BLOCK 206 ARE BASED ON THE BURNING OF 1 MMSCF/DAY OF NATURAL GAS FOR POWER GENERATION, ONE HELICOPTER LTO CYCLE/DAY, AND A 3500 HP SUPPLY VESSEL OPERATING 48 HOURS/L'EEK AT 701 CAPACITY. PRODUCTION EMISSIONS FOR BLOCK 205 ARE BASED ON ONE HELICOPTER LTO CYCLE/DAY AND A 30 KW GENERATOR OPERATING AT KIGHT HOURS/DAY. ALL OTHER EMISSIONS ARE CONSIDERED NEGLIGIBLE.

6. LEASE STIPULATIONS

THE ONLY APPLICABLE LEASE STIPULATION IS NO. 1 CULTURAL RESOURCE ASSESSMENT. IN A LETTER TO LESSEES DATED JULY 1, 1983, THE MINERALS MANAGEMENT SERVICE HAS DETERMINED THAT SOUTH TIMBALIER BLOCK 205 AND BLOCK 206 WOULD NOT LIKELY CONTAIN ANY SIGNIFICANT CULTURAL RESOURCES, THEREFORE THE PROVISIONS OF STIPULATION NO. 1 WOULD NOT BE APPLICABLE AND A CULTURAL RESOURCES REPORT WOULD NOT BE REQUIRED.

7. ESTIMATED LIFE OF RESERVES

THE RESERVE LIFE OF THIS DEVELOPMENT IS EXPECTED TO EE APPROXIMATELY 10 YEARS.

8. DESCRIPTION OF PROPOSED PLATFORM

THE PLATFORM SET ON BLOCK 205 WILL BE AN UNMANNED BOTTOM FOUNDED FOUR PILE DESIGN TO BE SET NEXT TO THE EXISTING TEMPLATE. BLOCK 206 WILL HAVE A MANNED BOTTOM FOUNDED EIGHT PILE DESIGN PLATFORM SET OVER THE EXISTING TEMPLATE. NO NEW OR UNUSUAL TECHNOLOGIES WILL BE DESIGNED INTO EITHER PLATFORM. EXHIBITS 8 AND 9 ILLUSTRATE THE TYPICAL PLATFORM DESIGNS TO BE USED. EXHIBITS 8A AND 9A DETAIL OUT THE KEY CHARACTERISTICS. EXHIBITS 8, 8A, 9, ANO 9A ARE PUBLIC INFORMATION.
