PLAN OF EXPLORATION 0CS-O5585 SHIP SHOAL BLOCK 358
Presented herein for your review and approval is the MOEPSl Plat, of Exploration for the above referenced lease.
Four wildcats are proposed to test potential reserves i n a faulted rollover structure in the Upper and Middle Pleistocene strata. This plan i s subject to revision as more detailed geologic information i s obtained during d r i l l i n g . Well locations and depths included i n this plan are as follows:
Well No. Surface Location
3550 FWL 1450 FSL
3550 FJL 1450 FSL
7190 FWL 7100 FNL
2250 FWL 4800 FNL

8. Environmental Report including CZM consistency c e r t i f i a t ion , shoreline proximity p l a t , and block plat shoving wel l surface

IJ The current! d r i l l i n g schedule calls for commencing d r i l l i n g operations on Ship Shoal 3S8 #1 on A p r i l 4,^1984. I t i s anticipated thatjeach well w i l l require approximately 60 days to complete, thus requiring a t o t a l of 240 days d r i l l i n g time for a l l four wells provided for i n this plan. The operations w i l l be serviced from MOEPSl's base i n Morgan City, Louisiana. No additions or expansions of existing f a c i l i t i e s or pesonnel w i l l be required.
A comprehensive O i l S p i l l Contingency Plan has been previously submitted and approved by the Deputy Conservation Manager in accordance with OCS Order No. 7. MOEPSl i s a member of Clean Gulf Associates and the equipment maintained by that organization at i t s Grand Is" Louisiana base w i l l be available for t h i s project i f needed. Deployme time of equipment i s 13-15 hours.
Your expedited review of this plan i s requested due to the spud date of Well No. 1 in early A p r i l 1984. MOEPSl i s presently conducting additional shallow seismic surveys on an expedited oasis on the subject leases. Additional information as required by NTL 83-3 w i l l be forwarded by February 25, 1983.
In accordance with Stipulation No. 2 to tiie subject lease, MOEPSl plan to I n s t a l l a shunt pipe and shunt a l l mud and cutting discharges to within 10 meters of the sea f l o o r . The shunt pipe tr.'.ll be attached to the semi-submersible r i g i n accordance with normal engineering practices.
I n order to help expedite this plan review, we are forwarding a copy directly to the Houma D i s t r i c t .
Should you have any questions regarding thi s submittal, please contact the undersigned at (504) 566-5582.
