Supplemental Plan of Exploration SS 190 Page 2

tA comprehensive o i l s p i l l contingency plan has been submitted t o the Minerals Ma^aner.ent Service, Regional Supervisor, in accordance w i t h OCS Order No. 7. This plan covers equipment, materials and procedures for prompt response to o i l s p i l l s . In addition, d e t a i l e d provisions f e r o i l s p i l l prevention are included i n OCS Order No. 2, which include? procedures for d r i l l i n g , j e t t i n g casing, blowout prevention and mud control.

The base of operations w i l l take place at Dulac, Louisiana. This base i3 5 acres in extent and employs twelve (12) persons as base personnel. Approximately 2% of the a c t i v i t y at t h i s base w i l l be applied to the p r o j e c t . In ad d i t i o n , the o f f i c e of FMP Operating Company in New Orleans w i l l allow approximately 1.0 person-years t o the subject p r o j e c t . No new employees w i l l be added, and no new f a c i l i t i e s are anticipated t o move i n t o the area.

FMP Operating Company i s a member of Clean Gulf Associates which maintains standby o i l s p i l l containment and cleanup equipment. This equipment includes skimmer systems f o r inshore and offshore waters, and aux i l i a r y shallow water and beach cleanup equipment. Personnel to operate the equipment are located i n Dulac, Louisiana. The f a s t response system and personnel could be on locat i o n i n 10 to 12 hours.

Your e a r l i e s t review and approval would be appreciated.

EXHIBIT 5 (2/2) SHALLOW DRILLING HAZARDS SHIP SHOAL BLOCK 190 MCMORAN NO. D

CLK Company, being under contract as geophysical consultants for McMoRan Offshore Exploration Co., as d i r e c t e d by McMoRan, have reviewed a l l a v a i l a b l e seismic data over and proximal to the surface location of the proposed well at 9400' FEL and 3650' FWL of Ship Shoal Block 190.

The data reviewed included: (1) an E-W l i n e 100' north of the location from a hazard survey conducted by John Chance and Asso­c i a t e s for Texaco in 1983, which c o n s i s t s of pinger (subbottom p r o f i l e r ) , side-scan sonar, magnetometer, and s i n g l s - f o l d sparker data; however, at t h i s time, Texaco has not been able to f i n d t h e i r sparker data. An Archeological and Hazard Report of Block 190 by John Chance and Associates for Texaco dated August, 1983, has a d e t a i l i n t e r p r e t a t i o n of these d*ta; (2) a N-S l i n e 150' east of the location from a survey conducted Dy Texas A&M for the USGS (now MMS) in 1972, which c o n s i s t s of subbottom p r o f i l e r and s i n g l e - f o l d sparker data; (3) a N-S l i n e 900' west of the l o c a t i o n from a survey conducted by ONI Offshore Engineering Surveys for the USGS i n 1975, which c o n s i s t s of subbottom p r o f i l e r , s i n g l e - f o l d sparker, side-scan sonar, and magnetometer data; and (4) a N-S CDP seismic l i n e across the l o c a t i o n which was shot by Geophysical S e r v i c e s , I n c., in 1983.

The average depth of penetration i s approximately 125' subsea (or 50' below mudline) on the subbottom p r o f i l e r data and approximately 700' subsea on the sparker data. The shallowest r e l i a b l e data on the seismic i s 700' + subsea. No anomalies were recognized on the data reviewed to i n d i c a t e shallow gas hazards at the proposed location. Referring to the John Chance report and maps, the location i s 1100' southeast of a NE-SW Trunkline 26" p i p e l i n e , 1400' west of a N-S Transco 26" p i p e l i n e , and 1000' NE of a magnetic anomaly.
