The tuffaceous red claystone typical of the\r\nPaleocene was encountered slightly above the log pick at 1669.5 m. The sandy\r\nbasal portion of the Paleocene was not well developed in 33/9-6. Oil and gas\r\nshows have occurred in this zone in both Statfjord and Murchison Field wells;\r\nhowever, no-shows were observed in 33/9-6. The objective Brent Group was encountered\r\nat 2995 m, 7.5 m low to prognosis. The sand was described as clear to white,\r\nfine grained and very micaceous. Porosity was poor to fair; and poor to fair\r\noil shows and scattered thin zones of bleeding oil were described down to 3023 m.\r\nNo shows occurred below 3023 m. Schlumberger Coriband Log analysis and core\r\ndata indicated 24.5 meters of gross pay and 13.5 meters of net pay, and an\r\noil/water contact of 3019.5 m. Based on this reserves for the horst block alone\r\nwere estimated at only ca 900000 Sm3 oil",
