The well has reached a depth of 4,718 m (15,479 ft), recording oil and gas shows while drilling through the main Lower Cretaceous APX-200 target horizon.
Currently the well is being deepened to evaluate additional targets. Progress has been slower than anticipated due to the need for a side track at 4,360 m (14,304 ft) for mechanical reasons.
Intermediate wireline logs indicate the possible presence, based on preliminary petrophysical analysis, of hydrocarbon-bearing sandstones.
The APX-200 contains around 40 m (131 ft) of net sand, with moderate porosities. However, without fluid samples it has been possible to determine the formation fluid (oil, gas, water), nor to accurately calibrate the petrophysical analysis.
Once the well has reached target depth a further set of wireline logs will be run. Subject to operational constraints, this will include a formation test tool that may be able to establish a pressure gradient within the sands and recover a sample of formation fluid to surface for definitive analysis.
FOGL is carried through this phase of drilling by Noble Energy in return for a 32.5% interest in the deeper targets. However, its overall share of the well costs has increased as a result of the various delays.
