The SAGW-13 appraisal well in the Sagiz West field in Kazakhstan reached a depth of 1,577 m (5,174 ft), and electric logs indicated 6 m (20 ft) of net oil pay over a 16-m (52-ft) gross interval in the Triassic formation at depths between 1,252 m and 1,268 m (4,108 ft and 4,160 ft). Reservoir quality is fair with porosities ranging from 15% to 20%, Max Petroleum Plc said.

Max also encountered visual shows over a lower reservoir at depths between 1,269 m and 1,304 m (4,163 ft and 4,278 ft) with electric logs indicating another 26 m (85 ft) of potentially productive reservoir, though there are higher levels of water saturation than encountered in the upper zone. The company plans to test this second interval for commerciality but has not characterized it as net oil pay at this time.
