- North = SUM ((MD2 – MD1) * Sin WD2 * Cos HAZ2)
- East = SUM ((MD2 – MD1) * Sin WD2 * Sin HAZ2)
- TVD = SUM ((MD2 – MD1) * Cos WD2)
Keeping this in consideration, how do you calculate true vertical depth?
True Vertical Depth (TVD) is measured vertically from the surface down to a certain target down hole. Measured Depth (MD) is the total length of the wellbore measured along the actual well path.
Furthermore, what is measured depth in drilling? In the oil industry measured depth (commonly referred to as MD, or just the depth), is the length of the borehole. In conventional vertical wells, this coincides with the true vertical depth, but in directional or horizontal wells, especially those using extended reach drilling, the two can deviate greatly.
Similarly, what is TVD in oil and gas?
In the petroleum industry, true vertical depth, abbreviated as TVD, is the measurement from the surface to the bottom of the borehole (or anywhere along its length) in a straight perpendicular line represented by line (a) in the image.
