Examples of True vertical depth in a sentence

  • B = True vertical depth at base of productive pay minus Kelly bushing elevation.

  • The unit will provide continuous 24-hour surveillance of drilling operations including the minimum:• Total gas detection• Chromatographic gas analysis• Continuous CO2 detection• Continuous H2S detection• Measured depth• True vertical depth as calculated from surveys• Rate of penetration• Weight on bit• RPM• Pump stroke rate• Mud pit levelsBefore surface casing is set, a single H2S sensor will be mounted in the possum belly and used to continuously monitor ditch gases for H2S.

  • True vertical depth at the top of productive pay minus Kelly bushing elevation.

  • To provide for increased pay and flexible conditions of employment for employees.

  • The reservoir top is set at 10500 ft (True vertical depth), and the properties that need to be specified are also given in Table 5.1. The dual-porosity model considers the fact that tight formation has a natural fracture network and the matrix compartments.


More Definitions of True vertical depth

True vertical depth means the vertical distance from a point in the well (usually the current or final depth) to a point at the surface. If the well is deviated, the measurement may be different from the “measured depth.”
Sample 1Sample 2Sample 3
True vertical depth means the difference in elevation between the ground level at the surface location of the well and the deepest point in the well bore.
Sample 1Sample 2Sample 3
True vertical depth means the distance from the surface to a point in the well bore which is the deepest subsurface depth drilled. True vertical depth is measured by utilizing a straight line perpendicular to the surface.
Sample 1Sample 2
True vertical depth means the vertical distance from a point in the well bore to a point at the surface,irrespective of the length of the well bore. (The length of the well bore is referred to as the measured depth).
Sample 1
True vertical depth means that depth at the point of entry
Sample 1
True vertical depth means the distance from the deepest point in the wellbore measured vertically to a point with the same elevation as that of the surface location. (Authorized by and imple- menting K.S.A. 2012 Supp. 55-152; effective Aug. 16, 2013.)
