Interim Results From WHI's 3D Seismic Survey in Seychelles Indicate Encouraging Oil Prospects

16/12/2014 by Sharon Shahzad


Preliminary results from 3D seismic surveys conducted in the Seychelles have backed up previous 2D survey data revealing 'potentially large' areas of hydrocarbons within the country's extensive Exclusive Economic Zone (EEZ), Australian oil company, WHL Energy has announced.

WHL was providing an update of initial interpretations of data gathered during the seismic survey of an exploration block known as Junon, 115 kilometres southeast of the main Seychelles island of Mahé by its partner FTSE-listed Ophir Energy between June and July this year.

The Indian Ocean archipelago of 115 islands is spread over an EEZ of 1.3 million square kilometres on a relatively shallow bank.

The small island developing state awarded offshore exploration rights to WHL Energy, which has spent the last year conducting seismic surveys in the exploration block known as Junon, situated south-east of the main Seychelles island of Mahé.

According to a recent press statement, WHL Energy said initial interpretations from the interim pre-stack time migration (PreSTM) revealed hydrocarbon structures in Junon East, Central and South, although it says that extraction in the southern part of the exploration block may prove to be risky.

"Junon Central is mapped to be a relatively simple tilted fault block closure covering approximately 20 square kilometres, and a structure of similar scale appears to be present at Junon East," read the statement." Additional possible new leads have also been mapped in the central Graben area, although these are of a more modest size."

The final and full volume of data processed for the survey, is expected to be delivered to WHL at the beginning of next year, and the company has said it hopes to see the commencement of test drilling during 2015.

WHL Energy's Managing Director, David Rowbottam, said the news was both "exciting and encouraging".

"It is also interesting that we are now identifying new leads as we continue to refine the processing of the large amount of data acquired in the Junon 3D seismic survey," he added.

WHL Energy holds a 12,856 square kilometre offshore exploration area in the Seychelles, at 25 percent equity.

The Australian energy firm signed a farm-in agreement with exploration operators Ophir Energy in March under which Ophir stands to earn a 75 percent stake in WHL's offshore Seychelles assets in return for an investment of up to $17.0 million on exploration, including the conducting of some 1500 square kilometres of 3D seismic surveying.
