Depth in a well

OverviewThe specification of depthDepth in a well as used in the oil and gas industryDepth in practiceFiguresExternal links

In the oil and gas industry, depth in a well is the distance along a well between a point of interest and a reference point or surface. It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, depth is a vertical coordinate related to elevation, albeit in the opposite direction. However, "depth" in a well is not necessarily measured vertically or along a straight line.

6 FAQs about [Rkb drilling rig]

How do you calculate depth of a drilling rig?

This depth is always calculated from the deviation survey. In most drilling operations, RKB (Rotary Kelly Bushing) is used as a reference point to measured depth. For floating drilling rigs, a mean rotary table elevation has to be used. In offshore, MSL (Mean Sea Level) is sometimes used.

What is the difference between RKB and MSL?

In most drilling operations, RKB (Rotary Kelly Bushing) is used as a reference point to measured depth. For floating drilling rigs, a mean rotary table elevation has to be used. In offshore, MSL (Mean Sea Level) is sometimes used. Variations in actual sea level from MSL can be read from tide tables or can be measured.

What is a rotary kelly bushing?

Depth measurements are commonly referenced to the RKB, such as 10,000 ft. RKB, meaning 10,000 feet below the rotary kelly bushing. RKB means rotary kelly bushing - an adapter that serves to connect the rotary table to the Kelly, which turns the entire drillstring.

How do you measure a wellbore depth from a kelly bushing?

Many wellbore depth measurements are taken from the Kelly Bushing. The Kelly bushing elevation is calculated by adding the ground level to the Kelly bushing height. Kelly bushing is that elevated device positioned right on top of the rotary table and used to transmit torque from the rotary table to the kelly.

What is a drill bushing?

Bushing that rotationally connects the rotary table to the drill string kelly bar, the top of which is commonly used as vertical reference for the drill floor. Coal: Did You Know?
