On May 5, 2005, Forest Oil contracted Tetra Technologies to conduct a turnkey abandonment of 11 wells on HI A466 Platform B. The original procedure to abandon this well was submitted to MMS Lake Jackson District Office on July 11 and approved July 12, 2005. This procedure was a standard procedure, but did not indicate the type of equipment that would be used to accomplish the abandonment. The procedure only mentioned pumps and wireline operations. On October 10, 2005, verbal approval was granted to Forest Oil allowing a coil tubing unit to remove obstructions on wells B-8, B-10, and B-11.
