| Abstract | ||||
| Kareem Formation is one of the Gulf of Suez's most significant hydrocarbon resources. It makes a substantial contribution to Egypt's overall oil production especially in Morgan and Badri fields. Kareem sand reservoir is deposited as a fan-delta environment, which erodes the high rift shoulders and deposits in the Basin. The present work deals with the petrophysical evaluation of Kareem Sand Reservoir at GS277 Oil Field which is the only oil reservoir in the field. Comprehensive well log analyses techniques were applied for a three-selected well in GS277 oil field. Those wells are named GS277-1, GS277-A4 and GS277-A5. The minimum suite of logs consisted of gamma ray, density, neutron, and resistivity logs; all the log data are in the form of LAS files. Specialized software was used for the petrophysical evaluation of Kareem sand reservoir in this study. In this paper , the essential petrophysical parameters were evaluated such as volume of shale (Vsh), effective porosity (Øeff) and water saturation (Sw). Also, cross plotting techniques are used for water resistivity (Rw) calculation and lithological identification for Kareem reservoir in the study area. The derived parameters from the petrophysical evaluation were used to calculate the standard tank oil in place (STOIIP) in Kareem sand reservoir in the study area. From the outputs of the petrophysical evaluation, it was found that Kareem Formation is a good reservoir rock in most intervals, where the interpretation of the well logging data indicates that the porosity ranges from 16% to 20% , shale content ranges between 5% to about 7%, water saturation from 20% to about 30%, and Net pay thickness ranges between 20 ft to about 50ft. The analysis of Lithological Identification cross plot for Kareem Sand reservoir indicates the presence of mixed lithology composed of sandstone and limestone. Petrophysical Analysis for Kareem Sand Reservoir in GS277 field indicate an enhancement for the reservoir properties towards GS277-A4 and GS277-A5 wells which may be highlight an opportunity for drilling a development well to maximize oil recovery from the field. Standard Tank oil in place (STOIIP) for Kareem sand in GS277 Field is calculated depending on the derived petrophysical parameters. The STOIIP ranged from 15 to 20 MMBO which highlighted a huge amount of hydrocarbons that is under developed. | ||||
