Australian energy company WHL Energy received an interim PreSTM data set for the Junon 3D seismic survey, offshore Seychelles, in mid-November and has started interpretation of this data.
The company said that the initial interpretation indicates that potentially large structures are present at Junon East, Junon Central and Junon South, although Junon South appears to have higher risk.
Importantly,WHL says, the scale of these structures appears to be similar to that previously mapped on the earlier 2D seismic data used to plan the latest 3D seismic acquisition. Junon Central is mapped to be a relatively simple tilted fault block closure covering approximately 20 km2, and a structure of similar scale appears to be present at Junon East. Additional possible new leads have also been mapped in the central graben area, although these are of a more modest size.
“WHL Energy is pleased to report that while the quality of the interim processed data volume is still challenging, the 3D data set is providing much more definitive mapping in the Junon area,” the company has explained.
The final PreSTM processed volume, which is expected to provide significantly improved data quality for the interpretation, is expected to be delivered to WHL at the beginning of 2015.
Commenting on the initial results, WHL Energy Managing Director, David Rowbottam , said: “It is both exciting and encouraging that this initial interpretation of the Junon 3D survey is confirming the potentially large structures identified on the 2D seismic data.“
“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.”
“We look forward to receiving the final PreSTM data set and the results of the ongoing interpretation, which we believe will provide even greater clarity and will further de-risk future exploration activities.”
