Abstract : In the Masila area, oil was first discovered in late 1990 with commerciality being declared in late 1991. Oil production at Masila began in July 1993. Total known oil-in-place exceeds 1.6 billion STB, with proved ultimate recoverable oil reserves approaching 900 million STB. The reserve estimates (Proved, Probable, and Possible) are in excess of one billion barrels of recoverable oil. About 90% of the reserves are found in the Lower Cretaceous Upper Qishn Clastics Member of the Qishn Formation. Production also comes from a secondary target within the Saar Formation. The scope of this study is the evaluation of hydrocarbons in the porous zones encountered in the Lower Cretaceous formations, penetrated by the eight wells scattered in the study area. Some points of interest will be considered in such process such as the geological aspects of the techniques utilized and the presentation forms of the obtained petrophysical parameters. The basic logging data exist in the form of spontaneous potential (SP), Caliper (CL), Deep (LLS and LLD), and Shallow (MSFL) resistivity logs, porosity tools (Density, Neutron and Sonic), Litho-Density Log (LDT) and Gamma-Ray (GR). Different crossplots such as Rho-PhiN, Rho-DTN, M-N plots were implemented for lithology identification of the two formations in the studied wells. Such formation evaluation and the presentation forms of the petrophysical parameters have proven that the formations have high hydrocarbon saturations in this area and containing many pay zones.
