Features of A Directional Well Profile:-

A directional well profile is the planned well trajectory from the surface to the final drilling
depth by projecting the wellbore onto two plotted planes. In order to determine the best
geometric well profile from the surface to the bottomhole target, the following information must
be known
• the position of the surface location,
• the position of the target location, and
• the true vertical depth (TVD).

A directional well profile is the planned well trajectory from the surface to the final drilling depth by projecting the wellbore onto two plotted planes. In order to determine the
best geometric well profile from the surface to the bottomhole target, the following information must be known the position of the surface location, the position of the target location, and the true vertical depth (TVD).

1.Kickoff Point (KOP)
The kickoff point is the location at a given depth below the surface where the wellbore
is deviated in a given direction.

2.Well Inclination

The well inclination is the angle by which the wellbore deviates from the vertical.

3.End of Buildup (EOB)
The end of buildup is the location where the wellbore has finished increasing.

4.Hold Angle
The hold angle occurs where the inclination of the borehole is held constant.


5. Tangent Section
The tangent section (hold section) occurs  after a buildup where the inclination of the borehole is held constant for a certain distance. There could be an additional build or drop before reaching the target.

6. Start of Drop
The start of drop is the location where the wellbore starts dropping inclination.

7.End of Drop (EOD)
The end of drop is the location where the wellbore finishes dropping inclination.

8. Target Displacement
The target displacement is the lateral distance from the surface location to the target.
