white rose oilfield development application - Husky Energy

1.2.1 Exploration HistoryThe first three wells drilled on the White Rose Significant Discovery Area, White Rose N-22, J-49 andL-61, were drilled between 1984 and 1986 (Figure 1.2-1). Results of these wells were encouraging, asoil and gas were encountered in all wells. Based on these results, the White Rose E-09 well was drilledin 1987-1988. This well was drilled into a separate structural culmination on the southern flank of thecomplex. It was the first well drilled in the South Avalon oil pool and encountered over 90 m of net oilpay, indicating the potential for commercial development.In 1999 and 2000, three additional delineation wells were drilled into the South Avalon oil pool, WhiteRose L-08, A-17 and H-20 (Figure 1.2-1). These wells confirmed the extent and quality of the reservoirencountered by the E-09 well.A fourth well, White Rose N-30, was also drilled in 1999. It was drilled into the North Avalon pool,downdip from the N-22 well. Results from this well provided additional information on the gas and oilcontained in the North Avalon pool and also provided data on the northern limit of the South Avalonpool.The four wells drilled into the South Avalon pool, together with detailed interpretation of threedimensionalseismic data, have established reserves of approximately 36 million m 3 (230 millionbarrels) of recoverable oil for the field.1.2.2 White Rose Reserves and DevelopmentThe extensive coring, testing and analysis of related data from the delineation program has given HuskyOil confidence in a depletion plan for reserves in the South White Rose oil pool. The depletion scheduleand reserves shown in Figure 1.2-2 and Table 1.2-1 (Reserves Summary) indicate the potential for theSouth Avalon oil pool.White Rose DA Project Summary • January 2001 Page 6
