Australia-based Santos said Wednesday it discovered a ‘significant’ oil pay zone at its Bestari-1 exploration well in offshore Malaysia.
The well encountered “high quality” oil bearing sands with good porosity and permeability.
Bestari-1 encountered 219 feet of net oil pay in multiple sand packages within the primary Miocene age formation at true vertical subsea depths ranging from 6,102 feet to 8,864 feet.
Oil samples, recovered from wireline pressure and sampling tools, confirm 27 to 30 degree API oil with no indication of H2S and negligible CO2.
The Bestari-1 well is located in the deepwater Block R production sharing contract and is currently being evaluated “with a view to planning an appraisal campaign,” Santos said.
Block R is located offshore Malaysia in water depths ranging from 328 feet to 4,593 feet.
Santos holds a 20 percent interest in the Block R PSC.
Japan-based JX Nippon holds a 27.5 percent operating interest in the PSC, Japan-based Inpex holds a 27.5 percent interest and Malaysia’s Petronras holds a 25 percent interest.
