Managed Pressure Drilling /7 0 votes, 0 avg 1 Created on March 09, 2023 Managed Pressure Drilling MPD-(number) 1 / 7 Why the BOP annular preventer shoud not be used during normal Managed Pressure Drilling (MPD) operations? To ensure the annular is in good conditions for well control operations The annular preventer is not rated for MPD operations That is not correct once the annular preventer is normally used on MPD operations The annular preventer is only used on conventional drilling 2 / 7 What is the main difference between conventional drilling and managed pressure drilling (MPD)? Conventional drilling allows drilling zones with narrower drilling windowns On MPD operations, a surface pressure is used to compensate the loss of the annular friction when the pumps are stopped to maintain BHP constant MPD operations should be used when the influx exceeds the kick tolerance Conventional drilling should be used only to kill wells with large gas kicks 3 / 7 What means “ramp down” schedule for your pumps while using a Managed Pressure Drilling (MPD) system? As the pump rate is reduce the annular friction losses (APL) is reduced and the surface backpressure (SBP) must be increased to maintain BHP constant. Starting your pumps as fast as possible to reduce the risk of formation fracture Reducing the liner size of your pumps to minimize the ECD Ensuring the pumps are properly and regularly inspected 4 / 7 What is not a main component of a Rotation Control Devide (RCD)? Sealing element Rig flow line Steel housing Bearing assembly 5 / 7 What means “ramp up” schedule for your pumps while using a Managed Pressure Drilling (MPD) system? Stopping your pumps as fast as possible to reduce the risk of influxes As the pump rate is increased the annular friction losses (APL)increases and the surface backpressure (SBP) must be reduced to maintain BHP constant. Increasing the liner size of your pumps to maximize the ECD Ensuring the pumps are properly and regularly inspected 6 / 7 A well was killed using the Driller’s Method. Bottom Hole Pressure (BHP) was balanced with a Final Circulating Pressure of 550 psi while pumping at 225 gallons per minute (GPM) with kill fluid at the bit. The decision was made to continue drilling using a Managed Pressure Drilling (MPD) system with a pumping rate of 450 GPM. What surface backpressure (SBP) is necessary while pumping at the new rate of 450 GPM? More than 550 psi Less than 550 psi There is no way to know 550 psi 7 / 7 If the Rotating Control Device (RCD) is leaking during Managed Pressure Drilling (MPD) operations, what should be done? Pick up off bottom, stop pumps and close the BOP Monitor the leak and continue drilling Increase the surface back pressure (SBP) to increase the Bottom Hole Pressure (BHP) Reduce the surface back pressure (SBP) to control the Bottom Hole Pressure (BHP) Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
