True vertical depth is the measurement of a straight line perpendicularly downwards from a horizontal plane. In the petroleum industry, true vertical...

a wellbore: the measured depth (MD) measured along the path of the borehole, and the true vertical depth (TVD), the vertical distance between the datum...

borehole. In conventional vertical wells, this coincides with the true vertical depth, but in directional or horizontal wells, especially those using extended...

Height above ground level Measured depth Normal height Orthometric height Thickness (geology) True vertical depth Vertical distance quantities, such as orthometric...

is the deepest human-made hole on Earth, which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. It is the result...

depth TVDPB – true vertical depth playback log TVDRT – true vertical depth (referenced to) rotary table zero datum TVDKB – true vertical depth (referenced...

vertical depth of the column has any relevance to the vertical pressure of any point within its column and the pressure gradient for any given true vertical...

"psi per foot." In the well-known formula P = 0.052 * mud weight * true vertical depth taught in almost all petroleum engineering courses worldwide, the...

to the true vertical depth of the column, not the measured depth, which is always larger than true vertical depth due to deviations from vertical. In the...

oil field. The well in the Tiber field had a true vertical depth of 35,050 ft (10,683 m) and a measured depth of 35,055 ft (10,685 m), below 4,132 ft (1...

exceeding length and depth oriented monitored drilling. Measuring the inclination of a wellbore (its deviation from the vertical) is comparatively simple...

measured depth of 9,800  ft and a true vertical depth of 9,800  ft while well Y has measured depth of 10,380  ft while its true vertical depth is 9,800 ...

TVD may refer to: True Vertical Depth, the vertical depth of the drill bit, used while directional drilling, especially when horizontal. Total variation...

technology in geothermal applications. The two wells attained a true vertical depth of 8000 feet, with horizontal sections extending 3250 feet. The project...

oil industry term for an oil well with a borehole that deviates from a vertically straight line. This is normally done with the intention of hitting several...

distinguish jumps that are commonly called plyometric and true plyometric jumps as exemplified in the depth jump which is illustrative of the shock method. Since...

formation fluid. Hydrostatic pressure = density of drilling fluid * true vertical depth * acceleration of gravity. If hydrostatic pressure is greater than...

Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the...

lifted well, filled with 1.2 sg brine from the shoe at 4070ftTVD (true vertical depth) to surface. In this well, the outside casing of the 'B' annulus...

the drilling-fluid density in pounds per gallon (ppg), TVD is the true vertical depth in feet and HSP is the hydrostatic pressure in psi. The 0.052 is...
