The Nigerian National Petroleum Corporation (NNPC) has invited contractors to provide 2D/3D seismic data interpretation service for lake Chad basin as well as other potential basins.
In an invitation published last Friday in national dailies titled: Provision of Seismic Data Interpretation Services in Onshore Frontier Basins, the company said the area to carry out the studies is approximately 3,550km of 3D seismic data.
Sources close to oil exploration in the Chad basin confided in Daily Trust that already the data gathering for the potential fields was concluded last year, and the next step is to analyse the data and interpret it in order to ascertain the potentials of the basin.
According to the scope of the work, there will be a review of past exploration campaign reports and studies including seismic and well data and their derivation, establish techtonostratigraphic framework for the study area including play type and identify and track faults across the whole seismic volume.
Other works to be done include generating of synthetic seismograms and tie seismic to well data, identify and track regional markers to delineate sub basins, generate time grids/maps of the tracked horizons, identify prospects, and generate time/depth maps.
The work, will also cover carrying out risk analysis and rank the prospects, propose drillable locations and prepare report among others.
Last year the Group Managing Director, NNPC Andrew Yakubu said the corporation has made huge progress in the oil search in the Chad basin at a meeting withVice President Namadi Sambo.
