RE: Supplemental Plan of Exploration High laland Block A-178 OCS-G 6206
Gentlemen:
In accordance with 30 CFR 250.34-1, FMP Operating Company requests your approval for a Supplemental Plan of Exploration for nine additional wells. Mell locations A, B and C were approved by your o f f i c e under a Revised Plan of Exploration on November 29, 1985. Additional well locatione G through O w i l l be d r i l l e d from the aame surface locations.
Please find the following exhibita enclosed:
1) Typical jack-up r ig and r ig equipment 2) Liat of Mud Components 3) Well Location Map 1) Vicinity Map re lat ive to ahor-line 5) Shallow Hazard Report 6) Geo .gicel Structure Map 7) Schematic Cross Section 8) Air Quality Report
Dril l ing operations are expected to commence by approximately February 21, 1986 and be completed in 270 days. At that time, we plan to review a l l avai lable well data and make a determination for further d r i l l i n g a c t i v i t i e s .
A comprehenaive o i l a p i l l contingency p.an haa been aubmitted to the Minerals Management Service, Regional Superviaor, in accordance with OCS Order No. 7. This plan covera equipmant, materials and procedure* tor prompt reaponse to o i l s p i l l s . In addition, detailed proviaions for o i l a p i l l prevention are included in OCS Order No. 2, which includes procedurea for d r i l l i n g , aettinq casing, blowout prevention and mud control .

The base of operations w i l l be locatad at Galveeton, Louiaiana. T h i s base ia 12 acres in extant and employe twelve (12) peraona aa base personnel, :pproximately 21 of the ac t i v i ty at thie base w i l l be appl i ed to the project . In addition, the o f f i c a of FMP Operating Company in New Orleans w i l l allow approximately 1.0 person-years to the subject project. No new employeee w i l l be added, the no naw f a c i l i t i e s ere antic ipated to move into the aroa.
FMP Operating Company ia a member of Clean Gulf Associates which maintaina standby o i l s p i l l containment of cleanup equipment. Thia equipment includee skimmer systems for inshore and offahore waters, and auxi l iary shallow water and beach cleanup equipment. Pereonnel to operate the equipment are located in Galveston, Texaa. The faat response ayatem and pereonnel could be on location in 8 to 12 houra.
Your earlieet review ar.d approval would be appreciated.
