PETE 4045 – Drilling Engineering Exam 1 – Fall 2017 Instructor: Dr. Mauricio Almeida Student Name:_________________________________LSUID:89-__________ Student Listing Number:_________ Exam Ty... pe: 1 General Instructions: x This is a closed book exam. x Besides your calculator, electronic devices of any kind (mobile phones, iPods, pocket PC’s, etc) are prohibited. x Do not detach any sheet from your exam. Questions 19 and 20 – Partial Credit Given: x You must show your calculations and box the final answer to receive full credit for your work. Use only the space allotted at the respective page to solve these questions. x If you need extra space to develop any question, you can use the final page to do so, but the content on that page will not be graded. x Failure to indicate the units in your calculation will result in losing points. x Make and state clearly any assumptions that you believe are necessary. 09/22/2017 Craft & Hawkins Petroleum Engineering Department Louisiana State UniversityFor Questions 1 to 10: Mark A for True or B for False, for the following statements: (15 points - 1.5 each) Question A(True) B(False) 1 The use of Trip Tanks (usually small in size) allows better detection of changes in fluid volume in the well, which is very important when monitoring hole fill-up during tripping operations. X 2 The well control system allows you: to close the well at surface, to move the drill string under existing pressure in the well and to divert flow away from rig personnel and equipment. X 3 If we are tripping out of the hole and the actual mud volume needed to fill up the hole is greater than calculated, this is a positive indicator of a kick in progress. X 4 Diverter is the equipment that serves as a seal between the well and the rig floor, diverting the annular flow coming from the riser. X 5 The arrangement of the BOP stack varies considerably. It depends on the magnitude of formation pressure in the area and on the type of well control procedures used by the operator. X 6 A mud gas separator permits any produced formation gas to be vented. X 7 The components of a typical blowout preventer stack are: annular preventer, at least one pipe ram, blind ram or blind shear ram and the Rotating Control Device – RCD. X 8 MWD specifically refers to measurements taken downhole in real time using devices located on BHA (Bottom Hole Assembly). This technique is typically used for higher cost directional wells. X 9 Motion Compensating System is used to avoid that horizontal movement of an offshore floating rigs gets transferred to the drill string, allowing the application of constant weight on bit. X 10 When the drawworks drum is almost empty of drilling line, the torque developed at the drawworks can be up to 20% greater than when it is completely full of drilling line. XFor questions 11 to 18: Mark the correct answer. 11- The mechanism principle shown in the figure below refers to which system found on a floating offshore drilling unit? (6 points) A- Coiled Tubing System B- BOP System C- Circulating System D- Riser Tensioning System E- Rig Inertial Navigation System 12- What types of vessel motion can be compensated for using flex joint and telescopic joint, respectively? (6 points) A- Rotational / Vertical B- Horizontal / Rotational C- Horizontal / Vertica [Show More]
