Jupiter ready to rumble in Kazakhstan

By Upstream staff


Australia’s Jupiter Energy has completed plans to re-enter the North West Zhetybai 2 (NWZ 2) well that was initially drilled on the Block 31 permit in Kazakhstan during the Soviet era.

The well lies on land that formed part of the extension to Block 31 which was approved by the Kazakh authorities in October last year.

A 3D seismic survey was shot over the western part of the block November and December last year, targeting both the NWZ 2 structure and the area adjacent to the adjoining Akkar North (Akkar N) oilfield.

The shoot confirmed that both areas offered very good potential for oil reserves, Jupiter said today.

Jupiter said a review of the logs from the Soviet-era NWZ 2 drilling programme showed that a 30 metre sand flowed oil to surface at 17.2 barrels of oil per day without acid or pump.

The company added that the 3D data shows that while the NWZ 2 well intersected with the Jurassic XIII sand, a location 1.5 kilometres from the well is more than likely to hit with both the Jurassic and Triassic structures in a crestal position. This new location will form part of Jupiter’s ongoing well drilling programme.

The original NWZ 2 well was drilled and cased at the same time as the NWZ 3 well, on the adjoining North West Zhetybai (NWZ) oilfield, was drilled.

The owner of NWZ has recently successfully completed the re-entry of the NWZ 3 well and has confirmed to Jupiter that the casing and overall condition of the well was excellent.

Based on this feedback, Jupiter said it is confident that the re-entry of NWZ 2 will be a success, allowing the company to produce oil by November this year.

The re-entered NWZ 3 is currently carrying out production testing and flowing oil at between 250 and 300 bpd and based on the NWZ 2 logs available to Jupiter, it is expected that NWZ 2 will flow at 200 bpd on production test.

The re-entry and extended flow programme is expected to cost about $500,000 and is fully funded.

The government approval process has begun and is expected to be received by early August and a drilling company experienced in completing re-entries in this area is ready to commence operations by the middle of August.
