| J Pursuant! to the requirements of 30 CFR 250.23.1 , Soh*o Petroleum Company sub
m i t s the f o l l ow ing Plan of Exp lora t ion (POE) f o r East Breaks Block 607.
(1) EXPLORATION ACTIVITY
The proposed exp lo ra t i on a c t i v i t y fo r East Breaks Block 607 cons is ts of d r i l
l i n g Wells "A, B & C" fron; three (3) d i f f e r e n t l o ca t i ons . A l l three 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 t ime to d r i l l these three (3)
exp lo ra to ry w e l l s i s about f i v e hundred ninety f i v e (595) days, w i t h a January
1 , 1988 an t i c i pa ted spudding date f o r the "A" l o c a t i o n .
(11) PROPOSED DRILLING RIG
Sohio present ly does not have a r i g under cont rac t f o r l oca t i on "A, B or C";
however, these w e 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 u n i t , s i m i l a r to the "Ben
Ocean Lancer" owned by Ben Odeco L im i ted . This r i g i s capable of d r i l l i n g i n
w a t e r depths of 4000*. The r i g ' s s p e c i f i c a t i o n s , bOP and D iver te r systems are
shown In Attachment A. S l i gh t mod i f i ca t ions can be made to the r i g In order to
handle the "C" l o c a t i o n , which Is 150* deeper than the r i g ' s l i s t e d maximum
opera t iona l water depth of 4000*.
M H ) GEOPHYSICAL WORK
A l l of the geophysical work preparatory to i n i t i a t i o n of exp lo ra to ry 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 l s when
t o t a l depth has been reached. No o ther geophysical work Is planned unless data
ob ta ined from d r i l l i n g operat ions 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
convent ional r e f l e c t i o n seismic methods.
Magnetometer and side-scan sonar requirements f o r the shal low hazard surveys
were waivered f o r t h i s block as shown in Attachment G.

Two (2) oodles of the shallow hazard report entitled, "Hazard Study Blocks
563, 564 4 60/, East Breaks Area", prepared by John Chance & Associates, Inc.
have been submitted with the PCE for East Breaks Block 563.
The East Breaks Hazard Study tas been reviewed by Mr. Jack Golcien, Sohio's
Regional Geophysicist. Letters from Mr. Golden in which he agrees with John
Chance's conclusions and addresses shallow hazards at each well site, are inclu
ded as Attachment B.
(1v) VICINITY AND LOCATION HAPS
Attachment C-l is a vicinity map depicting the subject tract's position rela
tive to the Texas shoreline. No new onshore fa c i l i t i e s w i l l be required for
dril l i n g these proposed exploratory wells. Existing service company facilities
1n the Sabine Pass Area have sufficient capacity to accommodate this project
without modification or expansion.
Attachment C-2 shows the proposed surface locations for Wells "A, B a C".
The total depth, water depth and surface locations for each of these wells Is as
follows:
Well "A" TD: 12,000' Water Depth: 3,180' Surface Location: 4,800' FNL
5.300' FEL
Well "B" TD: 13,700' Water Depth: 3,160' Surface Locat ion: 5,050' FNL
1,450' FEL
J
11,800' 4,150' 10,500' FNL 11,850' FEL
(v) STRUCTURE MAPS AND CROSS SECTIONS
Structure maps and cross-sections are included in the five (5) confidential
copies of this Plan as Attachment D. Depths s.'own on cross-sections and struc
ture maps are sub-sea measurements.
(vi) OTHER RELEVANT DATA
(A) Oil Spill Contingency Plan
Sohio Petroleum Company is a member of Clean Gulf Associates (CGA) and
would uti l i z e that organization's equipment to clean up an o i l s p i l l .
The closest CGA bases are at Galveston, Texas City, Texas and Cameron,
Louisiana, respectively. Response times for CGA Fast Response Units from
these three (3) locations would be 15, 16 and 19 hours, respectively.
Manpower to operate the CGA's equipment would be provided by Peterson
Maritime Services, Int., whose personnel are trained for o i l spill clean
up operations. Sohlo's supervisory personnel would direct the clean-up
operations until successfully completed. Additional details can be found
1n Sohlo's 1985 011 Spill Contingency Plan, which has been approved by
the Minerals Management Service.
(B) List 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, d r i l l i n g operat ions w i l l be conducted from the surface s i tes
described in sect ion ( i v ) using the mobile d r i l l i n g un i t described in
Section ( i i ) . Operations w i l l be of a maximum durat ion of f i v e hundred
ninety f i v e (595) days.
At the d r i l l s i t e , gaseous emissions w i l l be generated by the r i g en
gines, the at tendant work boat , stand-by boat, crew boat, and he l i cop te r ,
and the product ion t es t i ng of possible prospect ive rese rvo i r s . Gaseous
emissions a t the dock s i t e i n Sabine Pass, Texas, w i l l be generated by
the work boa t , crew boat and he l i cop te r . Onshore staging f o r t h i s opera
t ion w i l l be from e x i s t i n g f a c i l i t i e s , so there w i l l be no s i g n i f i c a n t
increase i n emissions f o r t h i s a c t i v i t y . Projected emissions from th i s
a c t i v i t y have been ca lcu la ted and are presented In the Projected A i r
Emissions Schedule as Attachment F.

Gulf Coast D i v i s i o n geophysicis ts conclude that no ! s i g n i f i c a n t shallow d r i l l i n g hazards e x i s t w i t h i n 500' of the East Breaks 607 "C" l oca t i on (10,500' FNL; 11 ,850 ' FEL; W.D. -4 ,150 ' ) .
The results and r e p o r t o f a shallow hazard survey conducted by John E. Chance and Associetes f o r Standard O i l Production Company over t r a c t 607 have been reviewed. We are i n agreement w i t h t h e i r f i n d i n g s and conclude t ha t :
1. No o b s t r u c t i o n s are observed on the sea f l o o r w i t h i n 500' of the proposed l o c a t i o n .
2. At least the upper 200* of sediment consist of ho r i zon t a l s t r a t a .
3. Sediments a t the sea f l o o r consis t of s i l t y c l a y .
4. No high pressure gas accumulations are observed w i t h i n the upper 1000* below mud l i n e or w i t h i n 500' of the proposed d r i l l s i t e . A f a u l t located 750' nor th dips to the south and o f f s e t s the sea f l o o r . At a 45° ang le , i t should i n t e r s e c t the w e l l bore at a depth of 750' below m u d l i n e .
