SPECULATIVE SEISMIC DATA

 

2D Speculative Seismic Data

Since 1989, various seismic contractors have acquired regional 2D seismic surveys in Equatorial Guinea territory under agreements with the Ministry of Mines, Industry and Energy. The most extensive survey (approximately 7600kms) was undertaken by Western Geophysical in 1998 over the previously unexplored deepwater areas. These data are available directly from Western Geco who should be contacted at their office in the UK. During 2002 reconnaissance seismic data were acquired around Annobon by GESeis.

More recently, in 2005 GESeis acquired a regional Long Offset 2D seismic survey as a precursor to the 2006 Licensing Round. 3D seismic data and Controlled Source Electromagnetic (CSEM) Surveys have also been acquired by GESeis.

 

Historical data Archive

Seismic (2D and 3D) and well data become the property of the Government on licence relinquishment. Some of these data are available2 to companies interested in evaluating exploration opportunities in Equatorial Guinea. Enquiries should be directed to the Ministry’s agent: RPS Energy Limited in the UK.

 

Interpretation and Analytical Studies

A synthesis report on the geology and petroleum potential of Rio Muni was produced by Exploration Consultants Ltd. (now RPS EnergyLimited) in 1997, including time and depth mapping based on the historical seismic data. The report identifies pre- and post-salt exploration targets and enables rapid evaluation of the exploration potential of the region.

Two analytical/interpretation studies were completed in 2001 that access the historical well sample archive and outcrops from Rio Muni. A Biostratigraphic Report by Lacustrine Basin Associates addresses the age, zonation and depositional environment of the Cretaceous strata through new sample analyses. A Source Maturity and Geochemistry study by ECL and Geotrack addresses the timing of source rock maturity and hydrocarbon migration through new sample and oil geochemistry and AFTA analysis.
