Total No. of Questions :8] P1121 [Total No. of Pages : 2 [3864] - 350 B.E.(Petroleum) OIL WELL DRILLING ENGINEERING (2003 Course) Time : 3 Hours] [Max. Marks : 100 Instructions to the candidates: 1) Question Nos.1 and 5 are compulsory. Out of the remaining attempt 2 questions from section - I and 2 questions from section - II. 2) Answers to the two sections should be written in separate books. 3) Neat diagrams must be drawn wherever necessary. 4) Figures to the right indicate full marks. 5) Use of logarithmic tables, slide rule, Mollier charts, electronic pocket calculator and steam tables is allowed. 6) Assume suitable data, if necessary. SECTION - I Q1) a) Discuss different stages in well planning and design. Explain in brief G.T.O. [9] b) For the existing conditions the drilling rate is 13 ft/hr and bit life is 33 hr. A mud company claims that spending $ 3000 more dollars on the mud will cause bits to drill 10% faster and 20% longer. The values for the bit and drilling conditions are given below. Bit=$1491 Tool = Stabilizer $ 120 Mud = $ 2000 (one cost component) Trip = 8 hr lost time = 0.3hr (one cost component), Rig rental = 550$/hr, support rental $ 250/hr Tool rental = 9 $ /hr (one cost component). Calculate drilling cost per foot with and without the consideration of new drilling mud. [9] Q2) a) Discuss design considerations in drill string for buildup angle. [8] b) How many drill collars should be run if maximum weight on bit is anticipated tobe 20 tonne, the average drill collar length is 9.2m the drill collar weight is 0.218 tonne/mtr and buoyancy factor of mud is 0.857.[4] c) Discuss different pressure losses in the drill string while circulation. [4] P.T.O. Q3) a) Discuss geometrical planning of type II (s-shape) directional well. [12] b) Find vertical and horizontal stress at a depth of 10,000 ft Assume [4] poisson s ration = 0.26 overburden gradient 1 psi/ft. Q4) Write short notes on: [16] a) Torque & drag in directional wells. b) MWD Tool. c) Multilateral wells. d) Ragland vector diagramme. SECTION - II Q5) a) Discuss in detail casing seat selection procedure. Discuss kick tolerence and differencial sticking point aspect. [9] b) Discuss classification of cement. Using following data, calculate pumping rate required to put cement slurry into turbulent flow in the annulus. Hole size 8.5" casing size 5.5" cement depth = 5000 ft(feet) I.D. of 5.5" casing is 4.60" n' 0.30 k' = 0.196 = 15.5 ppg. [9] Q6) a) Explain driller s method of well control in detail. [8] b) Mud weight =13 ppg SIDPP = 400 psi SICP = 450 psi Depth = 9000ft. Calculate kill mud weight. [2] c) Discuss different reasons and symptom s of kick in brief. [6] Explain hydraulic system (accumulator system) of BOP in detail. [8] Discuss BOP function test in detail. [8] Q7) a) b) Q8) Write short notes on: a) Casing design. b) Floating rigs. c) Subsea BOP stack. [16] jjj [3864]-350 2
