Drilling Fluids /4 3 votes, 5 avg 63 Created on February 20, 2023 Drilling Fluids 1 / 4 1. Which of the following drilling conditions can make it more difficult for the driller to detect a kick? A. High permeability formations with water based mud B. Low permeability formations with oil based mud C. Low permeability formations with water based mud D. High permeability formations with oil based mud 2 / 4 2. 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 3 / 4 3. You are currently drilling a high temperature well. The downhole mud temperature is significantly higher compared to the surface mud temperature. What effect will the high temperature have on downhole hydrostatic pressure? A. None, the mud in the well is a constant density B. It will decrease the effective mud density downhole and cause a lower hydrostatic pressure C. Temperature will not affect mud density D. It will increase the effective mud density downhole and cause a higher hydrostatic pressure 4 / 4 4. What happens to the primary well control barrier when drilling into an abnormally pressured formation? A. 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 Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
