Slow Circulating Rates /6 0 votes, 0 avg 1 Created on March 09, 2023 Slow Circulating Rates SCR-(number) 1 / 6 Which statement is correct about the slow circulating rates (SCRs)? Should be taken with returns throught the choke line Should be taken when drilling mud properties have changed Should be taken once a day Should be taken at at least 100 SPM 2 / 6 Why is it important to kill the well at a reduced pump rate? To prevent the casing from collapse To prevent the casing from bursting To minimize the effects of the annular pressure loss (APL) while pumping To prevent a pump failure 3 / 6 If the slow pump pressure (SPP) is unknown, how can the Initial Circulating Pressure (ICP) be determined? Hold the casing pressure constant until kill fluid reaches the bit Hold the drill pipe pressure constant until kill fluid reaches the surface Hold drill pipe constant while bringing the pump rate to the desired kill rate Hold casing pressure constant while bringing the pump to the desired kill rate, then switch to the drill pipe gauge to read the ICP plus the safety margin. 4 / 6 What is the effect of increasing the mud weight on the slow pump pressure (SPP)? The pressure losses will increase with heavier mud weight The pressure losses will decrease with heavier mud weight The pressure losses will stay the same with heavier mud weight There is no way to know 5 / 6 If the pump pressure at 40 SPM is 850 psi, what will be the pump pressure if the pump rate is increased to 60 SPM? 378 psi 1275 psi 1913 psi 1000 psi 6 / 6 If the pump pressure at 40 SPM is 800 psi, what will be the pump pressure if the pump rate is reduced to 20 SPM? 3200 psi 200 psi 400 psi 1000 psi Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
