Abstract

BED 2 field is one of the main producing assets for Bapetco company, Western Desert Egypt, BED 2 Field has hydrocarbon accumulations in Abo Roash, Lower Baharyia and, Upper Kharita formations. The field is a multi-reservoir started producing gas from Lower Baharyia and, Upper Kharita formations. The initial value of the field water saturation was calculated using Archie’s method where, it reached 20%. After years of production it was decided to monitor the reservoir and measure accurate water saturation using Thermal Decay Time (TDT) tools as the water cut increased significantly. The tool was run in X-3 well over Lower Baharyia and Upper Kharita formations. The hydrocarbon type is Gas-Condensate; the formation water salinity is well determined leading to decreasing saturation calculation uncertainty. Gas Water Contact (GWC) moved up by 9 meters and water saturation increased in Lower Baharyia and Top Kharita formations. The results revealed that the water production intervals must be isolated, resulting in decreasing of water cut and gas production increasing.
