Dear S i r :

Amoco is presently undertaking a high reso'iuticn geophysical survey over the above cited tracts that are located in water deoths of approximately 2,500'.

Available magnetometer systems are ine f fec t ive at these water deoths; and recent experience with side-scan sonar in comparable water ocbths has been very time consuming and prcdtced minimum resul ts .

We at Amocc believe that the safety of a d r i l l s i te can be more than adequately evaluated from the other Devices employed in a survey. Therefore, we are reouesting e waiver of tnese two oevices at the aoove ci ted t rac ts .

Should you approve, please complete as indicated anc r e t u " a copy for our f i l e s .
