Rift Oil announced that drilling on its PUK PUK–1 exploration well in PNG has now reached the upper reservoir objective at a depth of approximately 1760 metres, significantly higher than originally expected. Increased gas levels similar to those experienced in Douglas-1 were observed upon intersecting the ‘Alene Sand’ objective. The results are very encouraging at this stage however their full impact and significance will only be ascertained once electric logs have been obtained, which will only occur when drilling reaches its Target Depth between 1900 and 2000 metres. The main reservoir objective, the ‘Toro Sand’, is now anticipated to be penetrated below 1820 metres.
Flow testing is expected to be completed at PUK PUK-1 by the end of July at which point the potential of the field, and the impact of the discovery of gas at a higher level than anticipated, can be accurately assessed. Flow testing at Douglas-1 will follow and will be completed and assessed by the end of August.
