WebAbstract Exploring hydrocarbon in structural-stratigraphical traps is challenging due to the high lateral variation of lithofluid facies. In addition, reservoir characterization is getting more obscure if the reservoir layers are thin and below the seismic vertical resolution. Our objectives are to reduce the uncertainty of reserve estimation and to predict hydrocarbon … WebReferring to the well calibration workflow of Figure 6, relevant steps to perform here are: Set hydrostatic pressure gradient - Under Eaton, Hydrostatic Pore Pressure Gradient (ppg), enter the desired gradient. The default is 8.5 ppg, which is widely used, but depends on salinity and temperature. Pick shale indicators from logs.
