In perfectly vertical wells, the TVD equals the MD; otherwise, the TVD is less than the MD measured from the same datum. Common datums used are ground level (GL), drilling rig floor (DF), rotary table (RT), kelly bushing (KB) and mean sea level (MSL).
True
To calculate vertical thickness, you can use the formula: Vertical thickness = True thickness / cos(strike angle) To calculate true thickness, use the formula: True thickness = Vertical thickness * cos(strike angle)
There is no root word for vertical. Ver or vert is not true for vertical.
False. A pipe of a volcano is a vertical conduit that allows magma to rise from depth to the surface. It is typically a narrow, tube-like structure that connects the magma chamber to the surface vent of the volcano.
