The processing of new 3D seismic data acquired in August and September 2008 has been completed. The processed data is of exceptionally good quality. The new seismic maps now being generated are the first 3D maps of the Jebel Aswad structure and will offer very valuable information for the future development of Jebel Aswad field.
A total of 285 km2 of 3D seismic data was collected covering the entire hydrocarbon bearing Jebel Aswad structure. Previous seismic over the Jebel Aswad structure was 2D seismic with relatively low resolution and with sparse coverage over parts of the structure. The new seismic lines cover the whole structure, and are acquired with a geophone spacing of 15 x 15 meters.
“We are delighted that the processing has shown that the data is of outstanding quality. We can now look forward to maps giving more information about the Jebel Aswad structure than we could have hoped for. The new maps will enable us to re-evaluate reserve estimates with a higher degree of confidence, give us valuable knowledge for designing the re-entry and re-testing of the suspended JAS-2 well and give us crucial information for selecting an optimal location for the planned JAS-3 appraisal/delineation well,” commented Tethys’ Managing Director Magnus Nordin.
Tethys has a 40% interest and is operator of Block 15 onshore Oman covering the Jebel Aswad structure where the JAS-1 well in June 2007 tested a total of 2,626 boepd of natural gas and condensate. Danish company Odin Energi is partner holding 60% interest.
