Unformatted text preview: e successfully pressure tested (250 psi low/2,500 psi high) from above the top wiper plug at 18,115 feet. On September 10, BP conducted a 30‐minute pressure test of the 9‐7/8 inch production casing annulus that confirmed the lack of flow from the annulus. On October 7, 2010, BP perforated the 9‐7/8 inch casing between 9,176 feet and 9,186 feet and determined no u‐tube flow occurred from the casing to annulus. Based on this evidence, the Panel concluded that the well flow did not occur from inside the 9‐7/8 x 7 inch production casing or its related components (including the 9‐7/8 x 7 inch cross‐over sub and centralizer subs) from above the top wiper plug at 18,115 feet. 3. 9‐7/8 Inch Production Casing Shoe Track Based on the elimination of the potential flow paths from the previous scenarios, the examination of the blind shear rams that showed interior erosion, presumably from the high‐pressure flow of hydrocarbons past the rams in the period after the well event, and the findings contained in the Keystone Engineering Report, the Panel concluded that the most likely path of hydrocarbons during the blowout...
