Unformatted text preview: Assignment #10 PGE 424 w MMS 1. A resistivity log and an SP were used to obtain the following data: Formation resistivity (shallow investigation tool) = 5 ohm m Formation resistivity (deep investigation tool) = 25 ohm m The ratio of the mud filtrate resistivity to the formation brine resistivity is 2.0. The brine resistivity is 0.05 ohm m. The porosity from a density log is 0.2: (a) Estimate the water saturation in this zone. (b) Estimate the moveable oil saturation in this zone. (c) Estimate the recoverable reserves (in bbls per acre) for this field assuming a formation thickness of 20 feet and uniform porosity and saturation. 2. The p wave velocity for a formation containing oil and water is measured to be 11,200 fi/sec. Assuming reasonable values for the fluid velocity compute the following: (a) The porosity of the rock assuming that the formation is a sandstone. (b) The porosity of the rock assuming that the formation is a limestone. 22 141 50 SHEETS 22442 100 SHEETS 22-144 200 SHEETS 6 AMPAD RecovemML W 0404 —— 0.27.34 = 2 q) gmoveable *- h £311.. ’ .2 , My 3094?; *42540 y se x :l 15mm WW4 ‘5 WEE 22-141 50 SHEETS 22-142 100 SHEETS 22-144 200 SHEETS 61 _ AMPAD ...
