Harlin Knoll From : Deanna Harding [deanna@grinc.com] Sent: Monday, July 22, 2002 9:57 AM To: bsilva@secor.com Cc: Harlin Knoll; Roger Hoffmore; Bob Cochran Subject: RE: Request for 3Q02 M&S event for 93232, Stockton Brian ,. Total well depths were measured in all wells during the well development /2nd Qtr event ( s ) and noted on all field data sheets . The new wells were very difficult to develop ; full of sediment ( see field data sheets for initial total well depths and final total well depths reached after development ) . In addition , as field data sheets indicate and per our conversations , well MW- 6D was very difficult to develop , extremely thick mud , ( total well depth was supposed to be 62 ' , initial total well depth was 49 . 141 ) , well would not re - charge . After 3 events / attempts , we were able to get the well down to 57 . 05 ' . I will have Lancaster check/ confirm results . Deanna L . Harding Gettler - Ryan Inc .

The results from the three new deep wells was the reason he called . The corresponding shallow wells were ND while the deep wells , especially MW- 4D , had elevated levels of TPHg and benzene . This may be due to lab error , but in any event , he requested that during the next M&S event that the new well pairs have the bottom tagged prior to purging and sampling for well confirmation . If you have any questions please give me a call . Thank you , Brian A . Silva Project Scientist SECOR International Inc . 916 - 861 - 0400 ext 240 bsilva@secor . com <mailto : bsilva@secor . com> 1
