A well is completed with 6,000 ft of 2 7/8" tubing. The bottomhole static pressure is 2,000 psi and the PI is 0.25 BBL/Day/psi. Additionally, the GLR is 300 ft/BBL. Assuming a tubing head pressure of 100 psi, at what rate will the well flow? Use the gradient curves in the attachment.

9.14. Oil of viscosity 0.48 Pa-s and specific gravity 0.90 flows with a mean velocity of 1.5 m/s in a 0.3 m pipeline. Calculate shearing stress and velocity 75 mm from the pipe centerline.

The following criteria are needed to reach the "steady state" EXCEPT.. i. The water level in the test well is constant. ii. The water level in the observation wells is constant iii. Pumping in results to a drawdown curve. iv. The water level in all wells is of the same height

The pressure at a point inside a horizontal domestic pipe is 30 psi. It has a diameter of 4-in. and carries 300 gal/min of water. Unit weight of water is 62.4 pcf. Determine: a) The pressure head in feet of water, b) The velocity head; c) The Total Head with reference to a datum plane 20 feet below the pipe A clean, labeled sketch with hydraulic points of interest and any Datum shown Solution steps

Through the pipeline system in the figure calculate gauge and absulate presures at A and B

“For a well draining 80 acres, with thickness 80 ft and permeability 15 md, assume Bo = 1.2, μ = 1.8 cp, rw = 0.3 ft, and the flow is steady-state flow following the Vogel correction. Plot IPRs in one figure for skin va“ues of s = 0, 5, 10, and 20. Assume the reservoir and bubble-point pressure are 5000 psi.”

A parallel pipe net work connects the bottom of two reserviors. The head difference between the reserviors is 20 m. All three pipes have a ks value of 0.052. The lengths of the pipes are 70, 65 and 100 m and the diameters are 0.4, 0.35 and 0.5 m, respectively.  Determine the velocity in each of the three pipes.

Water resources engineering Please refer to the attached image. The new cat iron pipe carrying a flow of 0.3 ft3/s becomes divided at point B and rejoins at point C. The elevation at the reservior surface is 1300 feet. The elevation at point D is 560 feet. The pipe diameters and lengths are listed below. What is the pressure at point D? Neglect minor losses. Use the Darcy-Weisbach approach and assume fully turbulent flow. Verify this assumption for one of the pipes. If the assumption is not perfect, iteration is not necessary, just verify and comment.

There is a leak in a horizontal 30 cm pipeline (f= 0.025). Upstream from the leak two gages 600 m apart on the line show pressures difference of 140 kPa. Downstram from the leak two gages 600 m apart show a pressure difference of 126 kPa. How much water is being lost from the pipe?

A 1 ft pipe caries 1.0 cfs of flow at 120 psi. A gradual pipe contraction reduces the diameter to 8 inches.   Calculate:   a.  The tangential stress in the pipe upstream of the contraction if the wall thickness is 3/8 in. b. The force on the contraction fitting.
