Empire identifies two Perth Basin prospects

JETT RINK: Empire Oil & Gas has re-interpreted existing seismic data in Exploration Permit EP-430, together with recent seismic recorded in the Permit as part of the Garibaldi 2D Seismic Survey, which the company acquired in April.

The result has been the delineation of two new prospects; the Launer prospect and the Winchester prospect in EP 430 located in the onshore Perth Basin, Western Australia.

Empire completed the interpretation of all the seismic in August.

Three seismic events were mapped; these are the top of the Middle Jurassic Cadda Formation, the top of the Early Triassic Kockatea Shale, and the top of the Permian Dongara/Wagina sandstones.

The Launer prospect is a tilted fault block with structural closure mainly in the Jurassic Cattamarra Coal Measures and is located over both EP 430 and the EP 454 Permit, in which Empire has a 100% interest and a 50% equity respectively.

The company said its main objectives are the fluvial sandstones of the Early Jurassic Cattamarra Coal Measures sealed intraformationally.

It is considered likely that further seismic planned will provide structural closure at the Permian aged Dongara/Wagina reservoir levels.

“The potential estimated resource for the Cattamarra play for the Launer prospect, if hydrocarbons are discovered and the structure is filled to its spill point, is 16 million barrels of oil,” Empire Oil & Gas said in an announcement to the ASX.

“The prognosed total depth to drill the reservoir objectives is 1200 metres.”

The Winchester prospect is also located within the EP 430 Permit. Its structure has been interpreted by Empire as a four way dip closed compressional anticline.

Here, the company’s main objectives are sandstones of the Early Jurassic Cattamarra Coal Measures sealed intraformationally and sourced by the early Triassic aged marine shales of the Kockatea Shale.

“The potential estimated resource for the Winchester prospect, if hydrocarbons are discovered and the structure is full to its spill point, is 16 million barrels of oil,” Empire said.

“The Winchester prospect requires additional seismic which is planned for the first quarter of 2012.

“The proposed total depth of a well to evaluate the Jurassic Cattamarra Coal Measures section in the Winchester prospect is 1200 metres.”
