Project Profile
Location: 225 km north of Perth, Australia
Reserves: 2C Contingent Resource 360 BcF, 1.191 MMbbls of condensate and a best estimate Prospective Resource of 809 BcF
Production: 360 BcF and 1.191 MMbbls of condensate and a best estimate Prospective Resource of 809 BcF
Area: 297 km2
Depth: 3,840 metres
Start-up Year: 1991
On 22 October 2014 Eneabba acquired 100% of the prospective Ocean Hill Block Application (STP EPA 0090, formerly designated Bid Area L12-7), located in the north Perth Basin. The Ocean Hill application and Oil and Gas rights comprises 297 km2 and is located about 225 km north of Perth and 90 km southeast of Dongara and the Eneabba Centauri-1 Power station site.
The block area contains a large faulted four-way dip closure that was tested by drilling of the Ocean Hill-1 well in 1991. The well reached a total depth of 3,840m in the Jurassic Cattamarra Coal Measures before being suspended as an uneconomic gas discovery. Good gas shows were encountered in the Jurassic Cadda Formation and Cattamarra Coal Measures over the entire interval of over 800m from about 3,000m to total depth, and analysis of the electric logs indicated over 100m of net gas pay within multiple sands through the zone. An open hole drill stem test flowed gas rate of 0.7MMscf/d from the interval 3,063-3130mKB in the Cadda Formation with associated liquids of 15-23 bbl/MMcf.
The operator believes that Ocean Hill can be commercialised through the application of modern advances in 3D seismic, directional drilling technology and completion techniques and notes that gas prices are significantly higher than when the Ocean Hill-1 well was originally drilled. The Ocean Hill structure has two culminations and the northern one has been assigned 2C contingent resources of 360 BCFG and 1.2 MMBBL of condensate by an independent evaluation.
Following completion, the operator plans to carry out exploration on Ocean Hill in accordance with the permit application made by Green Rock to the Department of Mines, being a 3D seismic program and drilling of well in the next two years. Eneabba intends to secure a farm-in partner to assist with exploration funding.
UIL Energy Ltd. has completed the sale of shares agreement to acquire Eneabba Gas’ Perth Basin permit interests. UIL Energy has initiated the approval process for a sizeable 3D seismic work program over this prospective target. (September, 2016)
