| Popis: | Pore pressures are the fluid pressures in the pore spaces in the porous formations.Interactive Petrophysic (IP) software is used to determine the pore pressure gradient from logdata. These data are (GR log, Bulk Density and Sonic log).Surfer software is used to create the formation pressure distribution maps. These mapsshow the pore pressure gradient (PPG) for sex formations in contour forms. The formations arechosen depending upon the availability of formation in 11wells/11 fields. These maps areprovided the pore pressure distribution in middle and south of Iraq and eventually, give a clearimagination for high and low pressure regions for each formation separately.Six formation are considered in this research, these formations which existed in earlyCretaceous and late Jurassic (deep formations) are Shuaiba, Zubair, Ratawi, Yammama, Sulaiyand Gotnia.Finally, the outputs of these software helps to explain the abnormal pressure location andtheir distribution for the formation under study, this assists to expected the drilling mud programfor these formation. |
