Santos Completes Appraisal Well In Offshore Western Australia’s Bedout Basin
Drilling Activity Details
Drilling Activity Summary
Description
Sydney-based Santos Ltd. announced results from appraisal well #2-Dorado in the Bedout Basin, offshore Western Australia. The well was drilled down-dip approximately 2 km from #1-Dorado and hit 85 m of net reservoir in Caley. The oil-water contact was intersected at 4,003 m with 40 m of net oil pay encountered. An additional 11 m of pay was found in Upper Caley Sands—preliminary analysis indicates this upper zone is oil-bearing, and additional testing is planned. An additional 32 m of net pay was found in the underlying Baxter and Milne sandstones, and there was no fluid contact. Wireline pressure testing has confirmed that all the reservoirs are in pressure communication with the equivalent intervals in #1-Dorado. Hydro-carbon and fluid compositions are similar to the light oils and gases that were sampled in #1-Dorado. The appraisal well was drilled to 4,573 m and is in 91 m of water in permit area WA-437-P. The well will be plugged and abandoned, and the rig will be moved to drill exploratory #1-Roc South. Partners in the venture are operator Santos and Carnarvon Petroleum.
