High Island Block 177 OCS-G 6165

I n compliance wich 30 CFR § 250.34 and Notice to Lessees (NTT.) 84-1 of February 10, 1984, the following information is submitted for the planne ' development and production a c t i v i t i e s .

1. DESCRIPTION and 2. SCHEDULE

ARCO O i l and Gas Company spudded i t s f i r s t exploratory well (HI 177 Well No. 1) i n High Island Block 177 (OCS-G 6165) on July 17, 1988 at a SL of 6081' FSL & 7500' FEL. The well reached a TD of 14,000' MD (13,972' TVD) on September 13, 1988, at a BHL of 5909' FSL & 7222' FEL. The well was T & A'd on September 17, 1988, with the i n s t a l l a t i o n of a 48" caisson with NAVAIDS platform. The HI 177 No. 1 well discovered 36' (TVD) net effective gas i n the CM-13 interval from 10,322-10,370' MD and was determined to be commercially producible under 30 CFR § 250.11 (b) on August 25, 1988. The No. 1 w e l l also discovered 13' net gas i n the CM-14 horizon. Proven reserves are 12 BCF (CM-13) and 1.8 BCF (CM-14) with potential reserves of 45 BCF (CM-13) and 2.8 BCF (CM 4). RFT samples did not detect the presence of H2S but did show a C02 content; of 0.7%. The test also measured a BHP of approximately 7500 psi in the CM-14 and 6800 psi i n the CM-13.

The High Island Block 177 lease was acquired by ARCO Oil and Gas Company in OCS Lease Sale No. 74 and the i n i t i a l lease term expiration date was September 30, 1988. The lease is currently being held by the automatic 90 day leasehold extension (30 CFR § 250.13(a)).

I t is planned to fast track the development of th i s discovery to deliver natural gas to the market by January 15, 1989. In order to accomplish this accelerated development, ARCO w i l l salvage i t s depleted fou r - p i l e HI Block 68L "A" platform jacket, and the decks with production equipment from i t s depleted four-pile WC Block 238 "B" platform. The T & A'd HI 177 No. 1 well w i l l be completed with a MODU such as Teledyne Movible Offshore Inc. 's Teledyne No. 20. Completion operations are scheduled to commence on or about November 1, 1988. The completion operations w i l l serve as leasehold a c t i v i t y to continue the lease u n t i l production commencement. The modified four-pile jacket from the HI 68L "A" platform and the WC 238 "B" production equipment and decks are scheduled to be set over the completed HI 177 No. 1 well during the time period of November 28 through December 8, 1988. A 3 mile, 8-inch pipeline w i l l be l a i d from a hot-tap on Transco's 24-inch pipeline i n High Island Block 155 to the proposed HI 177 "A" platform (see Figure 5) during the time period of December 2 through December 19, 1988. Production commencement from the platform i s currently scheH ?d for January 15, 1989 (see Figure 9). I t should be understood that aix of these dates are subject to change due to winter weather, a v a i l a b i l i t y of materials, and schedules for crane barges, pipeline lay barges, and the d r i l l i n g u n i t .

3. LOCATION OF LEASE BLOCK. PLATFORM AND ONSHORE FACILITIES

High I s l a n d Block 177 Well No. 1 i s located some 22.8 miles from the nearest shoreline judged to be a point near U. S. Coastal and Geodetic Survey's benchmark "Caplen". A V i c i n i t y Plat of High Island Block 177 is given i n Figure 1. ARCO O i l and Gas Company w i l l use i t s e x i s t i n g Sabine Pass onshore base f a c i l i t i e s to support the development of the High Island Block 177 F i e l d . The Sabine Pass Shore Base is located i n Sabine Pass, Texas. One work boat w i l l average 1.5 round t r i p s per week. A crew boat w i l l be re q u i r e d vhen weather conditions r e s t r i c t h e l i c o p t e r operations. A frequency of one round t r i p per week may be re a l i z e d f o r a crew boat during d r i l l i n g operations. The frequency of hel i c o p t e r f l i g h t s frora the Sabine Pass Shore Base i s estimated to be 10 round t r i p s per veek. Helicopter f l i g h t paths w i l l f o l l o w the most d i r e c t route to and from the platform d u r i n g the development of the HI 177 Fie l d . The onshore a c t i v i t i e s associated w i t h the subject proposal should not r e s u l t i n any increase i n the size or number of onshore support and storage f a c i l i t i e s nor land or personnel requirements.

4. GEOLOGICAL AND GEOPHYSICAL DATA

Information on shallow geological and man-made hazards to d r i l l i n g and construction operations are contained i n a Marine High-Resolution Geophysical Survey Report by Gardline Surveys, Inc., that was included i n the Plan of Exploration (POE) f o r High Island Block 177. The l o c a t i o n of the HI 177 No. 1 wel l and the proposed HI 177 "A" platform i s w i t h i n 650 feet of the Shipping Safety Fairway leading i n t o the Galveston Harbor and w i t h i n 300 fe e t of a l a t e Wisconsin buried channel edge. The l o c a t i o n is also w i t h i n 450 feet of a possible accumulation of gas mapped at -23 BML. l n accordance with U. S. Coast Guard regulations (33 CFR § 166) the proposed "A" platform w i l l not be located w i t h i n the Shipping Safety Fairway and attendant vessels w i l l be anchored such that t h e i r anchor l i n e s are outside o f the fairway. The HI 177 No. 1 was d r i l l e d without any
