Re: Plan of Exploration 0CS-G-71o3 Block 765 Mustang Island
Gentlemen:
Block 7** was a t rac t purchased in the Federal OCS Sale Kc. 84 held on July I i - , 1984, for a lease bonus of $5,035,000.
The part ic ipants 1n th i s purchase are:
Block 765 Anadarko Production Company 33.75? Sonat Exploration Company 33.75? Pioneer Production Corp. 20.00-Energy Development Corp. 12.50"
Anadarko Production Coinpany is the designated operator for the block. Consequently, we are submitting the enclosed Plan of Exploration for your approval so that we may evaluate th is lease expedit iously.
One well locat ion is proposed 1n the Plan of Exploration and described in Section One, accompanied by:
(a) A location map showing the lease block re la t ive to the shoreline and onshore support-base f a c i l i t i e s .
(b) A map showing the location of the proposed we l l .
(c) One seismic structure map (Marg A) .
A f ina l construction hazards and archeological report from John E. Chance and Asso tes, I nc . , is enclosed under separate cover.
Plan of Exploration OCS-G-7163 Block 765 Mustang Island 2 February 7, 1985
nadarko Production Company's base of operations will be located 1n Port o'Conner, Texas. As an active member of the Clean Gulf Association. Anadarko has immediate access capability to the C.G.A. oil spill containment equipment stockpiled in Corpus Christi, Texas. The C.G.A. base 1s located approximately 36 miles from Mustang Island Block 765. Therefore, the oil spill equipment could be on site within 4 hours of notification. Anadarko Production Company has an 011 Spill Contingency Plan currently 1n your files. Also included, please f1.*H a l i s t of mud additives and components that could be used in the drilling program.
Exploration and any future production activity within the Mustang Island 765 area will be conducted 1n a manner consistent with state ar.d Federal requirements for coastal zone operations. The activities associated with this plan will be executed in compliance with all OCS orders and memoranda, and any required permits will be filed in a timely manner.
Anadarko, as an operator in the Gulf of Mexico and a member of the Clean Gulf Associates with the approved Oil Spill Contingency Plan on f i l e with the U.S.G.S., intends to exercise all diligence towards protection of the environment while implementing this Plan of Exploration.
Very truly yours,

Tht only txp lora tory w t l l (765 #A) w i l l be spudded as soon as permits ar t approvtd and a jack-up r i g is ava i lab le , which should bt in th t f i r s t quar t t r of 1985. I t is t xp tc t td to tokt an avtragt of approximately 45 days to d r i l l and complttt a w e l l . Upon d r i l l i n g and evaluating the r t s u l t s of our f i r s t w t l l , a dtc is lon would bt made concerning future development.
Tht "A" locat ion could bt completed and suspended with a template s t t ovtr t h t w t l l fo r l a t t r developmtnt in to a platform locat ion.
On December 18, 1984, John Chance and Associates conducted a high resolut ion geophysical survty of a portion of Block 765 for Anadarko Production Company. Instrumentation Includtd magnetometer, side scan sonar, sub-bottom p r o f i l e r , and 16 KJ sparktr single t rac t and mu l t i f o ld recordings.
No t v l d tnc t of cu l tu ra l r tsourcts is nottd on th t gtophysical data ga th t r td . Furthermort, th t archtological assessment implies that chances for damagt to such r t sources is t x t r tm t l y remote.
Hater dtpth at t h t s i te included in t h t POE is 118 f t t t with th t s taf loor dipping to t h t southtast at about 5 f t t t p t r mi le.
Sidescan sonar indicates a nearly featureless seafloor, the exception bt lng th t Imprint of th t Tenneco #1 w e l l . S imi la r ly , the only magnetic anomaly recorded re la t t s to that w e l l .
Sub-bottom p r o f i l e r and good qual i ty sparker recordings suggest th t ntar surfact to bt f r e t of fau l t ing and shallow gas.
In conclusion, t h t location in Anadarko's Plan of Exploration is found to be f r t t of any unusually hazardous conditions and chanco for damagt to cu l tura l r tsourcts
