I got the question from my friend, Nien, asking me about directional drilling calculation and the question is shown below:



Wellplanner is planning to design a deep kick-off well with a build section to by pass a salt dome section. He intends to achieve a horizontal departure of 1500 ft at the with the TVD at the target point to be 10,000 ft. Calculate the measure depth and build up rate.

The Minimum Curvature Method smooths two straight-line segments of the Balanced Tangential Method by using the Ratio Factor (RF).







The formulas for the Minimum Curvature Method are listed below;







β must be in radians







Where;

MD = Measured Depth between surveys in ft

I1 = Inclination (angle) of upper survey in degrees

I2 = Inclination (angle)… Continue
