Seal on open hole Seal on pipe Shears pipe Test casing 4 / 24 What is NOT a cause of premature breakage when using braided cable? Torque imbalance Bird caging Sweet service Stranding 5 / 24 Failure to keep the hole full, will affect which of the following? Fluid weight Formation pressure Hydrostatic pressure None of the above 6 / 24 What is the best way to confirm a primary fluid barrier failure? Test fluid density with a scale Increase in fluid temperature Improper displacement while tripping Check fluid temperature 7 / 24 How can hydrates complicate well control? Increases fluid weight Increases temperature Not being able to pump down tubing Reduces fluid weight 8 / 24 Which of the following could be used as a fluid barrier? Brine Check valve Gas column Cement 9 / 24 What grease injection pressure is required to maintain a pressure seal on a well with 3,200 psi MASP? 2,666 psi 3,840 psi 3,200 psi None of the above 10 / 24 What basic criteria are NOT applied to the selection and operation of all wireline pressure control equipment? Maintenance, pressure rating, and service type Design, manufacture, and repair Test, inspection, and documentation Visual inspection, function test, and pressure test 11 / 24 Which gasket is generally NOT recommended for use for BOP connections? RX R BX All of the above 12 / 24 What is a reason for de-rating the maximum safe working pressure of well control equipment? Leaking seal Corrosion Incorrect elastomers Leaking BOP 13 / 24 Identify the area of a lubricator in which pressure seals are critical. Female seal area Connection threads Stuffing box Quick connect collar 14 / 24 During the pre-job meeting, the wireline lifting equipment that requires certification was identified. Which of the following would NOT be identified as certified lifting equipment? Sling Lubricator clamp Wireline clamp Shackle 15 / 24 Identify a possible characteristic of fluids in workover/completion operations. Hydrate resistant High solids Forms a wall cake Hydrate sensitive 16 / 24 What are advantages of using a quick test sub (QTS)? Shorten lubricator length Saves on rig time and eliminates prospect of contamination of well with test fluid Allows to operate in higher wellbore pressures Allows for additional shut-in options 17 / 24 A non-shut-in well at 10,000’ with a gas influx volume of 5 bbls, what is the gas bubble pressure as the influx reaches 2,500’? Formation pressure is 4,000 psi. 16,000 psi 2,000 psi 1,000 psi 8,000 psi 18 / 24 What rig-assisted components are used during a wireline operation? Kelly/top drive Tongs Elevators Stand pipe 19 / 24 In a slickline operation, what is the first step to take when stuffing box is leaking? Stop the wire Close wireline valve Increase pressure on stuffing box Change packing 20 / 24 What slickline wire would be suitable to use on sour oil and gas wells? Stainless steel Carbon fiber High strength carbon steel None of the above 21 / 24 When considering the BOP equipment, which of the following is a non-shearable component?
