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. .
Although it is an intuitive concept, depth in a well is the source of much confusion because it is frequently not specified correctly. Absolute depth should always be specified with three components:• a. .
Specification of an absolute depth: in Figure 1 above, point P1 might be at 3207 mMDRT and 2370 mTVDMSL, while point P2 might be at 2530 mMDRT and 2502 mTVDLAT.. .

• Well depth values taken during the drilling operation are referred to as "". The "total depth" for the well, core depths and. .
• Unit: the usual unit of depth is the metre (m).• Path: common expressions of path are measured depth (MD) – elsewhere often known as along hole depth (AHD) – and true vertical depth (TVD). Note that using TV for true vertical.
[pdf] In this video we assemble a DIY micro drill rig (tiny DC motor + drill bit + frame) and a submersible water pump, then test drilling a small “well” and pumping water through tubing. I explain the mechanism, torque limits, and 3 upgrades for better performance.
