oil exploration history
OIL EXPLORATION HISTORY
  • 1950’S - Oil exploration commenced
  • 1960 to 1984 - 16 wells drilled mainly in the Lamu and Anza basins
  • 1981- NOCK was incorporated in 1981
  • 1984 GOK enacted new Petroleum (Exploration and Production) Act.
  • 1986 Petroleum (E & P) Act revised. Royalties replaced by PSC’s
  • 1985 to 1992 - Further 14 wells drilled
  • 1995 - Lamu Basin Study completed.
  • 2001 - Tertiary Rift Study complete
  • 2000+ - Award of offshore PSC’s and reinvigorated exploration
