Dear Erica:
Re: We1120-14
During the plugging and abandonment procedures for well 20-14, American Soda has
had significant difficulty installing bridge plugs or cement baskets. ASLLP has had
success establishing a cement basket on the short string 7" casing at a depth of 1470'.
During milling operations on the long string 7" casing, the mill bit twisted off at a depth
of 1441',
During subsequent fishing operations, ASLLP was unable to get the fishing tool past
1400' on the long string 7" casing.
On 6-3-2004, ASLLP performed a video inspection on both of the 7" casings on well 20-
14. The video inspection indicates a parted casing on both the long and short 7"
casings at a depth of 1394.6' The dissolution surface on well 20-14 is at 1442'. The
condition of the parted casing on the long string 7" casing prevents the insertion of a
bridge plug or a cement basket.
ASLLP proposes the following plugging procedure:
1. Run a 1 3/8" coil tubing as deep as possible into each 7" casing string.
2. Establish a 10' - 20' bentonite clay plug as deep as possible beneath the
parted casings on the 7" long string casing.
3. Establish a cement plug which extends above the parting of the casings.
