PLAN OF EXPLORATION
OCS-G-7201, BLOCK 618
MATAGORDA ISLAND, OFFSHORE, TEXAS
Union Oil Company of California proposes to d r i l l two (2) exploratory wells on the OCS-G-7201, Block 618, Matagcrda Island Area, Offahore, Texas. Drilling operations should commence in January of 1986 dependent of ric, scheduling. The wells are designed to test any and a l l prospective sands which might exist to a depth of 9,000' TVD in the Block (See Exhibit No. 1).
Well Data for OCS-G-7201, Block 618 (Exhibit No. 2)
Well No. Depth (TVD) Location Time (Days)
A 9,000' SL: 5400' FEL fc 6750' FNL 40 BHL: 3300' FEL fc 9450' FNL
B 9,000' SL: 3000' FEL fc 3700' FNL 40 BHL: 1250' FEL fc 6500' FNL
I f the exploratory project i s commenced as planned and the d r i l l i n g program i s continuous, this project should be completed in 80 days. Whether a l l two (2) wells are d r i l l e d w i l l depend upon the res u l t s of the f i r s t wells d r i l l e d .
The wells w i l l be dr i l l e d u t i l i z i n g a jack-up r i g similar to the one shown in Exhibit No. 3. The rig w i l l be a d i e s e l - e l e c t r i c d r i l l i n g unit and equippel with pans or sumps to collect grease or other pollutants. The liquids w i l l be stored in o i l drums for disposal onshore.
A l l wells d r i l l e d for o i l and gas w i l l be d r i l l e d in accordance with 30 CFR 250.34, the provisions of OCS order No. ? and the stipulations of the o i l and gas lease covering this block. No garbage, untreated sewage or other solid wastes shall be diapoaed from vessels. A l l solid combustible waste products w i l l be incinerated, taking great care not to endanger the r i g . A l l non-combustible material w i l l be transported to shore for disposal at our Surfside f a c i l i t y .
The d r i l l i n g operations w i l l be serviced from Union's shore base located at Surfside, Texas. The f a c i l i t y has docking f a c i l i t i e s for the marine equipment that w i l l be used on this lease. There i s a crane for loading and unloading materials. Union maintains
a small stock of tubular goods on the pipe racks. There are also helicopter pads whr»re personnel and supplies can be loaded to be flown to and from the rigs. The base i s manned 24-hours per day. Goods and services for the offshore operations are located in the Freeport and Houston areas and are easily transported to this f a c i l i t y by highway and marine transportation (See Exhibit 4).
Union Oil Company of California has filed an o i l s p i l l contingency plan with the Minerals Management Service in accordance with OCS Order No. 7. This plan contains the names and telephone numbers of company personnel who w i l l form an emergency response team in the event an o i l s p i l l . This plan contains procedures for reporting a s p i l l and for responding to a reported s p i l l . Union Oil Company of California i s a member of Clean Gulf Associates. This association provides for the purchase and maintenance of equipment and materials for use by the members in the clean-up of an o i l s p i l l . Equipment i s presently located at Galveston and Freeport, Texas; Cameron, Intracoastal City, Grand I s l e and Venice, Louisiana. Some of the equipment available include a shallow water skimmer system with 40-barrel storage capacity, a fast response open sea and bay system with two (2) 180-barrel tanks used in skimming and storing, a high volume open sea skimmer system with 1000-barrel storage capacity. The amount of time required to get to the s p i l l w i l l vary dependent or the location of company chartered work boats or the a v a i l a b i l i t y and location of work boats for immediate charter. Equipment response time should be within 24 hours of notification.
Exhibit Nc. 5 i s in compliance with the U.S.G.S. Gulf of Mexico l e t t e r 75-8 dated June 1974. This evaluation of bottom d r i l l i n g hazards was derived from a Multi-sensor Engineering Survey using Sidescan Sonar, Magnometer, and an Acoustic Profiler of Block 618. Based upon presently available geological, geophysical and archeological information, there are no known shallow d r i l l i n g hazards at the proposed location of the wells. A copy of the high-resolution survey data from the two lines closest to the proposed well locations i s included with one copy of the Plan of Exploration as per Paragraph II.A.5. of NTL No. 63-3.
Other relevant information and data as required includes the mud component and additive l i s t (Exhibit 6) and the Air Quality Statement (Exhibit 7 ) .
