PETROPHYSICAL LABORATORY INVESTIGATIONS OF ABU ROASH “C” MEMBER IN BED -15 FIELD, WESTERN DESERT, EGYPT

This study deals with the core analysis data of the Abu Roash ”C” Member in two wells : BED 15-3 and BED 15-7 wells. The studied parameters of the reservoir rock are the effective porosity, grain density, permeability and hydrocarbon saturation. The effective porosity allows the transportation of the fluid (oil and gas) throughout the interconnected pore spaces and the fluid permeability controls this process.
In well BED 15-3, it was found that from the statistical analysis of porosity data for the selected samples of Abu Roash ”C” Member shows that, the porosity values vary from 2.1 % to 19.8 % with an average value of 18.1%. On the other hand, the porosity of the same reservoir in well BED 15-7 ranges from 2.3 % to 20.5 %.
Also the permeability value varies from 0.02 md and 1052 md in well BED 15-3 well with an average value of 550 md, while it varies between 0.03 md and 668 md for the selected samples of BED 15-7 well with an average value was 334 md.
The water saturation data is between 16.1 % to 96.4 % in BED 15-3 well, and is between 5.4 % and 61.9% in BED 15-7 well.
The correlation between porosity obtained from the logging and routine core analyses versus depth for the Abu Roash “C” Member at BED 15-3 and at BED 15-7 wells indicates that the relationship is proportional andin good agreement. However, the Abu Roash “C” Member in the studied wells can be considered as a heterogeneous Member.
