QUESTION 1
A horizontal well with a measured depth of
10,000 ft. can be approximated as being
vertical to 2,000 ft, then a 5,000-ft segment
inclined at 60 deg, and a horizontal 3,000-
It section. Given:
2.000
Hole diameter (constant)= 8.5 in
Drillstring OD = 5 in
Mud weight = 10 ppg
Flow rate = 400 gpm
5,000 ft
60 deg
Calculate:
3,000 ft
a) The hydrostatic pressure at bottom (10,000 ft)
psi
b) The time necessary to bring the cuttings through the annulus, from the bottom to the
surface.
