250.34-1 EXPLORATION PIAN November 28, 1983

A BRIEF DESCRIPTION' OF THE PROPOSED TYPE AND SEQUENCE OF EXPLORATION ACTIVITIES TO BE UNDERTAKEN TOGETHER WITH A TENTATIVE TIMETABLE FOR THEIR PERFORMANCE INCLUDING PLAN COMMENCEMENT DATE, SEQUENCE EACH WELL IS TO BE DRILLED, TIME FRAME (DAYS) TO COMPLETE EACH WELL, AND TOTAL TIME TO COMPLETE THE PROPOSED PROJECT.

Amoco Production Company, 100%, acquired High Island 95 & 96 in Lease Sale 74, August 24, 1983 for a total of $7,074,000

High Island 95 6 9t> are located in 45' feet of rater 24 miles offshore and southwest of Sabine Pass at the

coastal border of Louisiana and Texas (See Attachment No. 1, Location Map).

Amoco's exploratory plan entails d r i l l i n g ten wells u t i l i z i n g a jack-up r i g . The proposed locations and depths of these wells are as follows:

A. Surface: 2,500' FEL & 7,800' FSL Blk. 96

B. Surface: 600' FEL & e.400' FSL Blk. 96

C. Surface: 300' FWL & 9,100' FSL Mk. 95

D. Surface: 1,300' FEL & 5,400* FSL Blk. 96

Exemption Formula

The distance o f the proposed f a c i l i t y from the c loses t onshore area of a state is 12 s t a t u t e miles:

The proposed f a c i l i t y is a t : l a t i t u d e 29° 2 1 ' 53.17" nor th , and longituc'e 94° 22' 23.79" west.

The closest onshore area of a s t a te is in Galveston county, Texas, a t :

l a t i t u d e 29° 30* ^ 2 . 5 1 " nor th , and longi tude 94° 29' 3.66" west.

This produces the exemption . mount of 399 tons/year f o r p a r t i c u l a r . , su l fu r d i o x i d e , n i t rogen oxiues and v o l a t i l e organic compounds, and the exemption amount of 17,821 tons/year f o r carbon monoxide.
