Task 2
Propose the well configuration design of the well based on the information given. State
your assumptions where necessary.
Target location: N 8346500 ft, E 397000 ft
Rig location : N 8350000 ft, E 400000 ft
Horizontal Departure:
= (8350000 − 8346000)
= 4609.77 ft
= 4610 ft

+ (400000 − 397000)
2
Bottomhole TVD: 11000 ft
Profile = Build and Hold (Type 1)
Build-up rate = 2.0°/100 ft
KOP = 2500 ft
A well with a Build and Hold profile has an initial deflection at a shallow depth which means it
has a low Kick Off Point (KOP). For this well configuration the KOP and BUR will be assumed to
be 2500 ft and 2.0°/100 ft respectively.
Radius of build-up,
Drift angle,
Measured depth at the end of build-up,
TVD at end of build-up section,
Horizontal deviation at the end of build-up,
Total measured depth to the target,
Task 3
Determine the number of casings to be installed and its estimated setting depth. Show
your work and methods you use. Use assumptions where necessary.
Task 4
Calculate the burst and collapse loads of each casing and propose the
casing grade (API) based on the calculations. You may refer to any casing and
tubing manufacturing sheet and put as reference in your report.
