Late last year, North Korea published veritable geological data made by North Korean and refutable Western oil engineers. North Korea plans to form a KEDO-like international consortium to bring up its black gold. In early October of 1997, North Korea and Japanese promoters organized a seminar on the hydrocarbon exploration opportunities in North Korea in Tokyo. Dr. Dong R. Choi , a Korean geologist, based in Australia and a technical adviser for Petrex Co. Ltd., Tokyo, presented a summary of the massive survey logs on North Korea's oil formations. Petrex Co.

Petroleum traps are anticline, fault-sealed, buried hills and stratigraphic types.
Seven wells have been drilled, recovering oil and gas from several wells and hydrocarbon shows from all of the wells. Reservoir rocks are Tertiary sandstone of a good reservoir physical property and fractured carbonate rocks which constitute the basement. Existing exploration data - Integrated geophysical surveys with a grid of 10 x 20 km throughout the basin, with a grid of 2 x 2 km over some parts. Two wells drilled, oil and gas shows found from both wells. He is one of the Japanese minority who genuinely desire close ties with Korea.
