Triangle Energy (Global) Ltd., Perth, has announced the results of a static model over the Cliff Head oil field region in production license WA-31-L in the offshore Perth basin of Western Australia that indicate new prospective resources in near field exploration targets.
The company says that the model reveals up to 29 million bbl of un-risked best estimate prospective oil-in-place. This includes 10.2 million bbl of prospective resource in prospects and leads close to the producing Cliff Head field. These prospective resources, if confirmed with an exploration drilling program, would benefit from the Cliff Head field’s existing pipelines and infrastructure without the need for costly installation of new infrastructure.
Triangle has remapped the subsurface to extend the geological picture over four areas to the west, south, and southeast of the producing field. These areas include seven new prospects that could lead to a multi-phased exploration/development program.
The company says the new model has taken an all-inclusive view of the Cliff Head field and ensured geological consistency across the discovered producing reservoirs and the prospective connected areas.
In past models the updating has been done incrementally as drilling and workover programs progressed. The new holistic approach has resulted in a consistent set of geological characteristics, including a single fault model, for the region. The seven new prospects can be delineated alongside the discovered oil in Cliff Head field itself.
Triangle will now plan an integrated development/exploration program to begin in 2019.
If the hoped-for resource increase is proved, it could extend the field production life into the 2030s.
