Question

34. Which of the following would increase flow from a reservoir into a well? Reduction of reservoir permeability Reduction of reservoir pressure Reduction of bottom hole pressure None of the above a. b. c. d. 35. Which of the following describes the operation of a pump jack-sucker rod va Traveling valve is open during the up stroke Standing valve is open during the down stroke Fluid moves upward in the well during both the up stroke and the do None of the above a. b. c. d. 36. A drill string is suspended in mud during drilling. How is drill sting elongat by mud weight? a. Drill string elongation increases due to buoyancy b. Drill string elongation decreases due to buoyancy c. Mud weight has no effect on drill string elongation d. None of the above

Answer 1

34) c; Reduction of bottom hole pressure

35) d: NONE OF THE ABOVE.

On the upstroke, the traveling valve is closed and the standing valve is open and on the down stroke, the traveling valve is opened and the standing valve is closed.

36) b; Drill string elongation decreases due to buoyancy

Because the Buoyed weight of drill string = String weight in the air x BF
