The well has now been shut-in for pressure build-up prior to an extended production test with down-hole pressure gauges to collect data for reservoir and productivity studies. The extended production test will be undertaken in the next few days, said Mosaic, which is operator and holds a 100% interest in the well and the Waggamba gas condensate field.

For 11 hours of the clean-up flow test, shut-in well head pressure at Waggamba-2, about 200m away, dropped from 2900psi to 2498psi, suggesting the two wells were in direct pressure communication.

Meanwhile in PL 119, Mosaic says the ADS Rig-6 is expected to arrive at the Downlands-4 appraisal well site by the end of the week.

Downlands-4 is the first well in Canadian junior Ausam’s PL 119 and ATP 471P Bainbilla Block Stage 1 farm-in program.

Ausam will fund the first $1.5 million of the Downlands-4 well costs and then contribute prorated interest for any costs above $1.5 million.

Mosaic currently holds an 83.3% interest in PL 119, which will be reduced to 60.9% following Ausam’s Stage 1 farm-in.
