Norwest Energy has encountered hydrocarbon pay at Xanadu-1 offshore Western Australia, and plans to extend drilling operations.

Xanadu-1 is in permit TP/15, 40km south of Dongara. TP/15 is in the northern Perth Basin about 280km north of Perth.

The shallow water well was drilled as a conventional oil exploration well, designed to test for the presence of hydrocarbons in the Xanadu prospect.

Norwest says drilling operations made excellent progress since the well was spudded on 4 September, and evaluation of the Xanadu prospect is ongoing.

Total depth (TD) reached late yesterday (17 September), confirmed that Xanadu-1 has intersected hydrocarbon bearing reservoirs demonstrated by elevated gas readings, oil shows, fluorescence and cut fluorescence while drilling reservoir section, the company says.

Drilling results have encourage the company and its joint venture partners to commit to running a wireline logging suite that includes pressure testing and fluid sampling. Logging is expected to begin within the next 24 hours.

The JV has a 7in casing string currently enroute to site from the north west, so that if logging results are positive, the well will be cased and suspended in preparation for an extended well test, once planning and approvals are complete.

The partnership has also agreed to extend drilling beyond the base of the High Cliff Sandstone to include the deeper sandstones of the Holmwood Shale, reaching a TD of 2035 mMDRT (TD previously 1863 mMDRT) on 17 September.

“I am extremely pleased to have these early positive indicators of hydrocarbons encountered during the drilling of Xanadu-1. Although further evaluation is required to understand the full potential, these are excellent first results. It’s been a while in the making, and now we have drilled the well,” says Norwest CEO Shelley Robertson.

Permit TP/15 occupies the 3 nm wide state territorial waters of Western Australia, adjacent to Port Denison, and covering an area of 645sq km.

Norwest is the operator of TP/15 with 25% stake. Partners include Triangle (Global) Energy Ltd. (30%), Whitebark Energy (15%), and 3C Group IC (30%).
