Abstract
Ras Fanar oil field is located in the western offshore concession area of Gulf of Suez, some 3 km.east Ras Gharib field in a water depth of about 100 ft. The main reservoir in Ras Fanar Field is the Middle Miocene reefal limestone (Belayim Nullipore). Middle Miocene Shallower Horizons Zeit Formation have locally proved potential in Ras Fanar oilfield, good represented by Zeit Sand Member (basal part of Zeit Formation) as secondary target. Zeit Sand secondary reservoir about 17 ft. average thickness, porosity ranging from 18-35 and average water saturation 15%. KK84-3 old Exploratory well Penetrated 15 ft. thick of Zeit sand and tested 350 BOPD from 10 ft. net Pay thickness , API 28.4 , reservoir driving by solution gas driving mechanism. Mud Gas Data analysis integrated with available logs and oil shows gives good indication to extension and reservoir characterization of Zeit sand. This paper show how you can detect low pay zone thickness while drilling by using Mud gas data analysis by multiple methods graphical and mathematical, it’s give excellent indication to select the interesting interval to run logs or well test and how can we improve reserve by integration between geological data and reservoir engineering data.
