WHL Energy Ltd. provided an update regarding the early interpretation of the Junon 3-D seismic dataset acquired within its offshore Seychelles project area. The company received an interim prestack time migrated dataset for the project in mid-November, according to a company press release. 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.

The scale of the structures appears to be similar to that previously mapped on the earlier 2-D seismic data used to plan the latest 3-D seismic acquisition. Junon Central was mapped to be a relatively simple tilted fault block closure covering about 20 sq km (7.7 sq miles), and a structure of similar scale appears to be present at Junon East, according to the release. Additional possible new leads have also been mapped in the central graben area, although these were of a more modest size.

While the quality of the interim processed data volume is still challenging, the 3-D dataset is providing more definitive mapping in the Junon area, WHL said. The final prestack time migrated processed volume, which is expected to provide improved data quality for the interpretation, is expected to be delivered to the company at the beginning of 2015.
