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).

What is the Difference between vertical and horizontal prototyping?
what is horizantal and vertical prototyping
Can depth be measured in negative numbers?
No, it is measured in positive numbers but it can be represented by negative numbers.
What is the opposite of height?
The opposite of a height is a depth. The opposite direction measurement of height (vertical) is width (horizontal).
Length times width times depth what does it measure?
Length times width times depth ( L x W x D ) measures cubic feet and must be measured in feet.
What do vertical and horizontal surface waves have in common?
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
How do you convert measured depth to true vertical depth?
To convert measured depth to true vertical depth, first write down the measured depth. You will have to map an X, Y, Z point from that calculation, as well as using the azimuth and inclination.
What does depth mean in measurements?
It is usually a linear measure in the vertical direction, measured downwards. If measured upwards, the same measure could be called a height.
What is vertical erosion?
Vertical erosion is when the depth of the river is greater than the width causing erosion to take place on the bed of the river. This is also when lots of water enters the river but not as much is exiting it.
How is water depth measured?
The depth in the ocean is measured by sounding using echo-sounders. Nowadays satellites are also used for this purpose.
What were shaft mines?
Access to a seam or ore body at greater depth is done by a vertical or nearly vertical path known as a pit or a shaft. In India, above 30 metre s depthshafts is used as access
Relationship between liquid pressure and depth?
The greater the depth, the greater the pressure.
How are floods measured?
Floods are measured by a known level of depth. If the water level is over that depth, it may be considered a flood.
Why is water greater at a greater depth than at a shallow depth?
Because of the weight of the water above.
What is the Difference between vertical and horizontal prototyping?
what is horizantal and vertical prototyping
What is vertical speed?
Vertial Speed is final depth minus intitial depth divided by time
Can depth be measured in negative numbers?
No, it is measured in positive numbers but it can be represented by negative numbers.
What is the full form of xyz analysis?
Horizontal, Vertical, Depth
