Abstract | ||||
Surface geological methods can help to identify the interesting sub-surface structures which may contain fluids, but are unable to predict whether they contain hydrocarbons or not. Accordingly, there is no solution other than drilling a well to really determine the presence of hydrocarbons below the surface. Formation evaluation is a process in which borehole measurements are used to evaluate the characteristics of subsurface formations. The primary objectives of formation evaluation are: the identification of reservoirs, the estimation of hydrocarbons in place and the estimation of recoverable hydrocarbons. Gebel El Zeit area has only one oil producing field which is Ras El Ush (REU) Oil field. The TDT interpretation for different REU Field wells resulted in divided the Matulla Formation into different intervals within each well, while the Malha Formation did not be covered by the TDT log in some of these wells. The SW varies, in the intervals of the Matulla Formation, from 30% to 80%. Gas zones were observed in some wells and the GOC were detected. The Malha Formation is a clean sand formation with little kaolinite volume in most wells. The thickness of the Tarmat section is about ±78 ft, above the OWC, within the Malha Formation. The Tarmat section has the same depth and almost has same thickness in all wells. It separates the oil, above, from the water, below. | ||||
