3D Oil seeking partner for new permit in Australia

3D Oil seeking partner for new permit

3D Oil has been awarded a new exploration permit, WA-527-P in the Roebuck Basin off Western Australia. The company filed a bid on the permit in the December 2016 Australian Offshore Gazettal round.

The permit W-16-8 covers an area of 6,590 km2 with average water depths of 120m (65-168m). 3D Oil says the permit is lightly explored covered by a broad grid of 2D seismic data of varying vintages and has no exploration wells.

The company is planning on seeking a farm-in partner to the permit.

WA-527-P is located to the east of a series of recent oil and gas discoveries uncovering a new petroleum province. These discoveries were made as result of the 2014-2016 exploration campaign led by the Quadrant joint venture. These discoveries indicated the Roebuck Basin is a significant petroleum province opening up the potential for success in nearby areas.

The exploration campaign began with the drilling of Phoenix South-1 in 2014, which discovered a series of discrete light oil zones within sands of the Lower Keraudren Formation. This was followed by the drilling of Roc-1 and Roc-2 during 2015-2016 which resulted in the discovery of gas-condensate within the stratigraphically lower Caley Sandstone. There is a significant liquids component to the hydrocarbons with a Condensate Gas Ratio of 20-40 bbls/MMscf, 3D Oil said. The reservoir has proven excellent with sustained flow testing from Roc-2 resulted in up to 11,500 Barrels of Oil Equivalent per day.

Phoenix South-2 drilled adjacent to Phoenix South-1 at the end of 2016, also resulted in a gas-condensate discovery within the Caley Sandstone. The well encountered a 39 meters hydrocarbon zone, however, was unable to test an additional 185m of potential hydrocarbon bearing reservoir due to elevated pressures. These elevated pressures are thought to indicate the presence of yet more hydrocarbons. Carnarvon Petroleum, in the Quadrant JV, yesterday quoted recoverable resources of 143 BOE (P mean) for the Caley Sandstone and 16.7 MMbbl for the Barret Sandstone.

“The Joint venture clearly considers the area to have remaining potential as they have planned the drilling of the Dorado-1 well later this year located up dip of the Roc structure. The results of this well could have implications for WA-527-P prospectivity as 3D Oil’s view is that the target could be within a similar geological setting of the identified leads,” 3D Oil said.

The evaluation of WA-527-P undertaken by TDO included a review of the existing seismic data, licenced Spec Data and a full petroleum systems analysis. The petroleum system uncovered by the recent discoveries is interpreted to be active nearby and partly within to WA-527-P.

The Minimum Guaranteed Work Programme consists of studies in Years 1 and 2, and the acquisition of 510 km2 of 3D seismic in Year 3.
