In a water flooding experiment the pressure gradients in the displacing and displaced phases are 400 psi/ft and 350 psi/ft

Q. In a water flooding experiment, the pressure gradients in the displacing and displaced phases are 400 psi/ft and 350 psi/ft, respectively. Assume that the displacement front is stable in the absence of capillary and gravity forces. Consider that only water flows upstream and only oil flows downstream of the displacement front. Then the mobility […]

In an active water drive during a certain period, the rate of production and reservoir pressure remain constant

In an active water drive during a certain period, the rate of production and reservoir pressure remain constant

Q. In an active water drive during a certain period, the rate of production and reservoir pressure remain constant. The water influx into the reservoir from the aquifer is 6000 bbl/day. The surface oil and water production rates are 3000 STB/day and 1500 STB/day, respectively. The current production gas to oil ratio is 825 SCF/STB,

In a drilling rig, the crown block and the traveling block have three and two sheaves, respectively

Q. In a drilling rig, the crown block and the traveling block have three and two sheaves, respectively. A single wireline connects the hoisting drum to the deadline anchor as shown in the figure. Neglect the weight of the pulleys and the wireline, and friction between the sheaves and wireline. The ratio of the deadline
