It will decrease the hydrostatic pressure overbalanace B. It is impossible to know C. It will increase the hydrostatic pressure overbalance D. It will not change the primary well control 2 / 4 2. What effect does increased temperature have on fluid density? A. It will increase fluid density B. It will reduce fluid density C. Temperature has no effect on fluid density 3 / 4 3. Oil-based mud has a higher compressibility. How does the mud compressibility affect the lagging time between choke adjustments and drill pipe pressure changes? A. Decrease the time B. There is no way to know C. Has no effect on the time D. Increase the time 4 / 4 4. How can wellbore total pressure affect non-aqueous (oil-based) mud density downhole? A. Well depth will not affect the mud density downhole B. Increasing hydrostatic pressure downhole can increase effective mud density in the well C. Increasing hydrostatic pressure downhole can decrease effective mud density in the well D. It iOnly the density of water-based fluids will be affected by the total pressure in the wellbores impossible to know Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
