Pursuant to ' the requirements of 30 CFR 250.23.1 , Sohio Petroleum Company sub
mi ts the f o l l ow ing Plan of Exp lo ra t ion (POE) fo r East Breaks Block 563.
(1) EXPLORATION ACTIVITY
The proposed exp lo ra t i on a c t i v i t y f o r East Breaks Block 563 consis ts of d r i l
l i n g Wells "A, B, C & D" from four (4) d i f f e r e n t l oca t i ons . A l l four locat ions
w i l l be d r i l l e d as s t r a i g h t ho les . The estimated time to d r i l l these four (4)
exploretory w e l l s 1s about s ix hundred s i x t y f i v e (665) days, w i th a January 1 ,
1988 ant ic ipated spudding date f o r the "A" l oca t i on .
( i l ) PROPOSED DRILLING RIG
Sohio p resen t l y does not have a r i g under cont rac t f o r l oca t ion "A, B, C or
0 " ; however, these we l l s w i l l be d r i l l e d w i th a d r i l l i n g un i t s i m i l a r to the
"Ben Ocean Lancer" owned by Ben Odeco L imi ted . This r i g is capable of d r i l l i n g
1n water depths o f 4000' . The r i g ' s s p e c i f i c a t i o n s , BOP and P1v<?rter systems
are shown in Attachment A.
(111) GEOPHYSICAL WORK
A l l of the geophysical work preparatory to i n i t i a t i o n of exp lora tory opera
t i o n s has been completed. A v e l o c i t y survey may be run on these we l ls when
t o t a l depth has been reached. No o ther geophysical work i s planned unless data
obtained from d r i l l i n g operations necessi tates a d d i t i o n a l d e f i n i t i o n d e t a i l from
conventional r e f l e c t i o n seismic methods.
Magnetometer and side-scan sonar requirements f o r the shallow hazard surveys
were waivered f o r t h i s block as shown In Attachment G.

563, 564 & '607 , East Breaks Area" , prepared by John Chance & Associates, Inc .
are submitted w i t h t h i s POE.
The East Breaks Hazard Study has been reviewed by Mr. Jack Golden, Sohio's
Regional Geophys ic is t . Let ters from Mr. Golden in which he agrees w i th John
Chance's conclus ions and addresses shal low hazards at each wel l s i t e , are i n c l u

( v i ) OTHER RELEVANT DATA
(A) 011 S p i l l Contingency Plan
Sohio Petroleum Company i s a member of Clean Gulf Associates (CGA) and
would u t i l i z e tha t o rgan i za t i on ' s equipment to clean up an o i l s p i l l .
The c loses t CGA bases are at Galveston, Texas C i t y , Texas and Cameron,
Louisiana, r espec t i ve l y . Response times f o r CGA Fast Response Units fro.7!
these th ree (3 ) locat ions would be 15, 16 and 19 hours, respec t i ve l y .
Manpower t o operate the CGA's equipment would be prov ded by Peterson
Maritime Serv i ces , I n c . , whose personnel are t r a i ned fo r o i l s p i l l c lean
up opera t ions . Sohlo's superv isory personnel would d i r e c t the clean-up
operations u n t i l success fu l l y completed. Add i t i ona l d e t a i l s can be found
in Sohio's 1985 Oi l S p i l l Contingency Plan, which has been approved by
the Minerals Management Serv ice .

(B) L.4s| of Mud Components
'attachment E is a l i s t of the proposed d r i l l i n g mud components and addi-
tives, including the common and chemical trade name of each additive.
(C) Gaseous Emissions
Exploratory drilling operations wil l be conducted from the surface sites
described in section (iv) using the mobile dri l l i n g unit described in
Section (11). Operations w i l l be of a maximum duration of six hundred
sixty five (665) days.
At the d r i l l site, gaseous emissions w i l l be generated by the rig en
gines, the attendant work boat, stand-by Doat, crew boat, and helicopter,
and the production testing of possible prospective reservoirs. Gaseous
emissions at the dock site in Sabine Pass, Texas, w i l l be generated by
the work boat, crew boat and helicopter. Onshore staging for this opera
tion w i l l be from existing f a c i l i t i e s , so there w i l l be no significant
increase in emissions for this activity. Projected emissions from this
activity have been calculated and are presented in the Projected Air
Emission Schedule as Attachment F.
(D) Coastal Zone Management (CZM) Consistency Certification
A Coastal Zone Management Consistency Certification for activities des
cribed 1n this plan is not required.

Mr. Sandridge Texas District

OCT lti 1935 J
Dear Mr. Sandridge:
1 am wri t ing to request a waiver of side-scan sonar and magnetometer requirements as stated in NTL-83-3 our deep-water contiguous blocks. East Breaks 563, 564, 607. The water depths across these blocks are 2800-4200 feet.
The problem wi th acquiring side-scan sonar and magnetometer .-lata in very deep water is getting the sensor near the ocean f loor . Although good results can be obtained with the towfish anywhere from 10 percent to 50 percent of the range scale above the seafloor, optimum results occur when the towfish is 10 percent of the range scale above the ocean floor.
As with any towed submerged device, the depth of the sensor is a function of cable length and speed through the water. Generally, a cable length-to-depth ratio of 3-4:1 can be expected at tow speeds adequate for successful gathering other high-r tsolut ion data required bv NTL-83-3. namely seismic and bathymetric data. Our hieh-resolution contractor has proven electrical cables of 16,000 feet in lengtn. This would indicate that acquir ing side-scan scnar data in depths of 4000-5000 feet is possible under ideal conditions but only at great expense to the operator. If ocean currents were very mild , a 4.000-foot towfish depth could be obtained with 16,000 feet of cable deployed. The line extensions to get f u l l side-scan sonar coverage immediately becomes three miles and boat turns absorb an enormous amount of time. We have to survey f ive blocks to get coverage in one. I f conditions exist that prevent one from getting required depth at conventional speeds, one must then run the survey twice: once at manageable speeds to acquire seismic and bathymetric data, and once at slower speeds to get side-scan sonar data.
Knowledge of the position of the towfish. i . e . , where is data being gathered, is another important question. Ultrashort baseline acoustic tools can be employed, but generally experience ranges no greather than 10,000 feet, equalling a f ish depth cf 2.500 feet maximum.
Mr. Sandridge MMS TEXAS DISTRICT October •/., 1>85 Page 2
Long baseline/ acoustic positioning systems can be employed where transponders lare deployed on the oce-in floor. These devices usually experience ranges equal to„ or shorter than the ultrashort baseline positioning systems, therefore numerous transponders would have to be deployed to survey a single block. These devises dre very expensive since an acoustic release must accompany each transponder. Also, surface interrogation equipment is expensive and recovery of the transponders is less than 100 percent.
All in a l l . it would seem that the practical depth limit for acquiring i e c i to' . l i"; v'L. t I i i f
of expensive and exotic tools and/or procedures.
Very truly yours .
