“The company’s exploration manager, Loren Ware, felt that the North Slope of Alaska was the best bet for a large discovery and in 1958 began the first steps in the exploration process.
During 1964 & 1965, the company had to choose between two upcoming sales, one in the Colville Delta, the other in the Prudhoe Bay area. It had seismic evidence of a large structure in both areas. The company chose the Colville Delta sale, as it was first.
The BP-Sinclair Colville # 1 (1966), penetrated a thick section of Permian Triassic deltaic oil- stained sandstones possibly the Sadlerochit. This gave the financially troubled oil company the first indications of a potential oil field on the North Slope. However, for financial reasons, and despite the efforts of Ware, Sinclair did not bid in the Prudhoe Bay area sale.”
