Block S2 Milestones:
1992: The first oil discovery within the
boundaries of Block S2 was made by Occidental in
the Kohlan Formation in 1992 (exploration well
“Kharwah-1 ”).
1998: Occidental relinquished the area and
Preussag acquired same in 1998.
2001: In March/April of 2001, and after
reinterpretation of Karwah-1 well results,
Preussag re-entered the well and conducted a
multi rate test.
2002 – 2003: Preussag continued in an extended
well test followed from November 2002 until
October 2003. The well produced an average oil
rate of approx. 380bbl/d without any water and
without any significant pressure depletion. The
test interpretation concluded that the well was
producing from the Kholan Formation with an
additional unknown rate from the crystalline
Basement.
