Kazakhstan-focused Max Petroleum announced Tuesday that it had achieved successful drilling results at an appraisal well in the Sagiz West field.
The SAGW-13 appraisal well reached a depth of 5,175 feet, with electric logs indicating 19 feet of net oil pay over a 52-foot gross interval in the Triassic formation at depths of between 4,108 feet and 4,160 feet. Max said that the reservoir quality is "fair", with porosities ranging from 15 percent to 20 percent.
Max said it also encountered visual shows over a lower reservoir with electric logs indicating another 85 feet of potentially productive reservoir, albeit with higher levels of water saturation than found in the upper zone. The company also plans to test this interval for commerciality, but has not yet characterized it as net oil pay.
The well is located just over a mile southwest of SAGW-4, making it the most southern well drilled on the field to date. Production testing is set to start soon, while the Zhanros ZJ-30 rig will now move to drill the SAGW-7 well – the final well in Max's current appraisal drilling program at Sagiz West.
