1 . Description of Developaent Act iv i t ies
Santa Fe International Corporation Is operator of leases OCS-G-6042/7202, Matagorda Island Block 633/634.
Matagorda Island Block 633 was obtained through a faraout f roa Aaoco. Nell No. 3 was d r i l l e d In Noveaber 1968, and tested two Intervals froa 7400'-7500' at +5 MMCFD each and TPIA. A DOCD for th is wall was subaitted to the "Minerals Nanageaant Service on May 29, 1989 and approved on June 30, 1989. Well No. 3 was coapleted In June 1990 with a plat fora and fac i l i t y deck Insta l led thereafter. This well wat placed on production In Deceaber 1990.
Under the revised Plan ot Exploration for Matagn-da Island 633 Well No. 4 was dr i l led In July 1990 and encountered 128' of nat pay which tested +6 MMCFD froa the bottoa 20' Interval and temporarily abandoned.
Matagorda Island Block 634F was acquired In the July 1984 Lease Sala -Well Ko. 1 was d r i l l e d In March 1989 and ancouncered 55'-60' of net pay which tested 14 MMCFD plus 100 BOPD and temporarily abandoned. Well No. 2 was dr i l l ed In September 1989 and temporarily abandoned In Noveaber 1989. Santa Fe plans to re-enter Well No. 2 In Apr i l 1991 and directionally d r i l l the wall to a new BHL. This should prove up an additional 6 BCF of gas. A Moss I I structure Is to be Instal led upon coapletion of d r i l l i n g operations.
Santa Fe proposes to do the following work under this DOCO.
Install a four p i l e , seven well production platfora 1n Matagorda Ml and Block 633.

In accordanca with Laasa Stipulation No. 1 attached to lease for Matagorda Island Block 634F, Santa Fe International Corporation subnltted a Cultural Resources Report to the Minerals Managenent Service on June 18, 1985 which was reviewed on August 6, 1985 and satisfied the requirements of Notice to Lessees and Operators No. 75-3 (Revision No.
In accordance with Lease Stipulation No. 3 attached to leases for Matagorda Island 633/634F, Santa Fa will notify tha Chief, Naval Air Training, Naval Air Station, Corpus Chr ist i , Texas regarding air and boat operations affecting the Military Wanting Area W-228.
Santa Fe International Corporation 1s environmentally sensitive to the wildlife In the Matagorda Island Area and agrees to abide by the two conditions covering endangered whooping cranes and the Brown Pelican mentioned in Minerals Management Service letter dated April 13, 1990 approving our Revised Plan of Exploration.
7. Discharges
Listed below ara the discharges to be Incurred during dr i l l ing and production operations. Any discharge will be done within the guidelines as set forth In the Final NPDES Permit dated July 9, 1986.
Drillinq Operations
Tho anticipated discharge rates for Santa Fa's dril l ing operations for Matagorda Island Blocks 633/634F are l isted balow:
* Basad on SO gals/parson/day with average 40 persons on board.
The quantity of discharge of cuttings Is based on the average hole size for each section of hole. Mud nay ba discharged for purposes of dilution or at the end of the well. Fifty percent (50*) for attached liquids to cuttings Is addad to give a total dr i l l ing fluids discharge. Sewage Is treated on location. Solid domestic wastes are transported to shore for proper disposal at an authorized disposal s i te .
The fluid used for dri l l ing will be a typical lignosulfonate nud, unless otherwise noted In the drill ing prognosis. Concentrations of the chemicals In tha mud can ba estimated from the dally fluids chemical Inventory. Other surveillance of the fluid Is accomplished by the monthly and end-of-well LC 50 toxicity tests required by tha EPA. A 11st of mud additives that nay ba usad while conducting development dril l ing operations 1s enclosed as Exhibit 9.
In no Instance wil l the dril l ing fluid discharge rate exceed 1,000 bbls/hr.
Any drilling fluid contaminated with oil will be transported to shore for proper disposal at an authorized disposal s i te .
Production Operations
The volume of produced water discharge Is presently unknown. However, all produced watar discharges will be monitored In accordance with the EPA NPDES Permit.
The Natagorda Island Production platform will be manned after dril l ing operations are completed.
Deck drainage Is estimated to be approximately 900 bbls/month from the structure.
I f any solid wastes ara generated on the platform, these wastes will ba transported to shore for proper disposal at an authorized disposal s i te .
8. Hydrogen Sulfide
Narathon, McMoran and Amoco has previously drilled wells 1n Matagorda Island Block 633 and no H?S was encountered. Santa Fe dril led Well No. 3 to a depth of 8246' and Well No. 4 to a depth of 8950' and encountered no H2S in either wel l .
In Matagorda Island Block 634F, Santa Fa drilled Wall No. 1 to a dapth of 13.935' and Wall No. 2 to a dapth of 10.055' and ancountarad no H2S gas.
Therefore, In accordanca with 30 CFR 250.67, Santa Fa haraby requests that a determination ba mada, that drilling and production oparations will taka place whan tha absanca of hydrogen sulfide has baan confirmed.
9. Coastal Zone Consistency
Certificate of Coastal Zone Consistency Is not applicable.
10. Projected Emissions
See Exhibit 10 for Air Quality Report.
H. Environmental Report
Environmental Raport 1s not applicable.
12. Onshore Base
Matagorda Island Blocks 633/634 ara located approximately 10 miles from shore in watar depths of approximately 80 feet. A map showing tha location of Blocks 633/634 relative to the shoreline and onshore base Is enclosed as Exhibit 11.
Santa Fe Intamatlonal Corporation will utilize the existing onshore facilities located at Harbor Island Terminal In Aransas Pass, Texas. This will serve as port of debarkation for supplies and craws. No onshore expansion or construction Is anticipated with respect to this activity.
This base 1s capable of providing the services necessary for tha proposed activities. It has 24 hour service, a radio tower with a phone patch, dock space, equipment and supply storage base, drinking and drill water, etc. This will serve as our base of operations for Matagorda Island Blocks 633/634. During drilling oparations, a supply boat will maka a round trip every three days, a crew boat will maka a round trip aach day and a helicopter will make two (2) round trips per week. During production activities, a supply boat will make one (1) round trip per week and a helicopter will make two (2) round trips pcr week.
The onshore activities associated with Matagorda Island Blocks 633/634 should not result in any increase in the size and number of onshore support and storage facilities or land and personnel requirements.

V I . Findings o ' A i r Quality Review
As per DOI-MMS regulations, th is f a c i l i t y is exempt from further air quality review as i t has been determined that i t s operation w i l l not have a s ign i f i cant adverse environmental iapact on a i r qual i ty . Calculated eaissions are for a worst case condition. Actual eaissions froa this project w i l l probably be lower.
VII. Methodology
Dri l l ing - horsepower-hour/ft d r i l l e d method Boats - horsepower-hour method Helicopters - landing/takeoff (LTO) cycle method All Others - horsepower-hour method
