Application of reservoir lateral prediction technology in Stubb Creek oilfield of Nigeria

Stubb Creek oilfield has an area of 42 km2,and the research layers are C3,C7,C9,D1,D3,D5 and D8in Agbada formation.According to the existing 4 drilled wells and the present understanding of achievements,to carry out well log normalization,well-to-seismic calibration and the sequence division of systems tracts,and the studies of rockphysics and lithofacies.Through various seismic facies and in combination with single well facies,to describe favorable facies belt of the seven layers mentioned above.By using support vector machine(SVM)technology to carry out frequency division inversion of shale content.With the sandstone shale content threshold value to calculate the sand body thickness of the above 7 layers.C9 and D3 were screened to be the two favorable facies belt.Under the control of favorable facies belt,top structure map through sand body and contour map of sand body thickness were carved and then a comprehensive evaluation was carried out.
