Question: For the following vertical well: 9 - 5 / 8 CSD: 1 3 , 5 0 0 ft Next TD: 1 6 , 5 0

For the following vertical well: 9-5/8 CSD: 13,500 ft Next TD: 16,500 ft F.G. @ 9-5/8 casing shoe: 0.8 psi/ft Surface temperature: 73 Temperature gradient: 0.02/ft Max. mud weight for the next hole: 14.5 ppg Max. pore pressure gradient at the next hole: 0.75 psi/ft Open hole diameter: 8.5 Assume the drillstring only consists of drilling bit and 5.5 drill pipe. a. Calculate the kick tolerance for the following cases: a. Gas (density =2.5 ppg) b. Oil (density =7 ppg) b. Discuss the effect of temperature on the kick tolerance when the formation fluid is gas. c. Also, discuss the effects of MW, FPP, and type of formation fluid on the kick tolerance. Calculate the burst resistance for the 9-58"N-8043.5lbft casing, if 0.13" of the casing wall
thickness gets worn out.
a. Compare the new burst resistance with the original value.
b. How does this phenomenon (casing wear) affect the casing design process?
For the following vertical well:
9-58" CSD: 13,500ft
Next TD: 16,500ft
F.G. @ 9-58" casing shoe: 0.8ft
Surface temperature: 73F
Temperature gradient: 0.02Fft
Max. mud weight for the next hole: 14.5 ppg
Max. pore pressure gradient at the next hole: 0.75ft
Open hole diameter: 8.5''
Assume the drillstring only consists of drilling bit and 5.5" drill pipe.
a. Calculate the kick tolerance for the following cases:
a. Gas (density =2.5ppg)
b. Oil (density =7 ppg)
b. Discuss the effect of temperature on the kick tolerance when the formation fluid is gas.
c. Also, discuss the effects of MW, FPP, and type of formation fluid on the kick tolerance.
