AWE Pleased with Lengo-2 Well (Indonesia)

AWE Limited reports that at 0600 hours yesterday local East Java time (0900 hours Sydney) the Lengo-2 appraisal well, offshore Indonesia, was at a measured depth (MD) of 757m (2,485 ft), running in hole with a core assembly in preparation for cutting a second 27.5m (90 ft) of core in the primary objective Kujung 1 carbonate reservoir.

To date a single core has been cut from 739m to 757m (2,425 to 2,485 ft) recovering an estimated 17.7m (58 ft) of carbonate Kujung 1 reservoir formation. The Kujung formation has subsequently been drill stem tested (DST) over an interval from 736m to 757m (2,415 ft to 2,485 ft). This interval flowed gas at a rate of 4.5 million standard cubic feet per day (scf/d) and has achieved a maximum flow rate of 4.6 million scf/d. Gas samples were collected and compositional analysis will be undertaken over the coming days.

The results of the test confirm that the previously untested upper part of the primary objective at Lengo-1 has reservoir quality sufficient to contribute potential future production at the Lengo-2 location. These results are in line with pre-drill expectations and, subject to a successful evaluation of the composition of the gas, plans remain on track for the well to confirm the accumulation as suitable for a future commercial development.

AWE’s Managing Director,Bruce Clement, said “The results to date are in line with pre-drill expectations and are providing us with valuable data that will help us progress the Lengo field to a commercial development decision”. 

The forward plan is to cut a second 27.5m (90 ft) of core in the primary objective, followed by  wireline logging and a second DST that will evaluate the entire Kujung 1 formation intersected. The well will then be deepened to a total depth of approximately 830m (2726 ft), tagging basement. This will be followed by the final wireline logging program which represents the last step in the Lengo-2 appraisal well evaluation. On completion of the logging program, the well will be plugged and abandoned as planned.
