Break Circulation - To establish circulation of drilling fluids after a period of static conditions. Circulation may resume after a short break, such as taking a survey or making a mousehole connection, or after a prolonged interruption, such as after a round trip..

Hydrostatic pressure in drilling refers to the pressure exerted by a column of drilling mud or fluid within a wellbore. It is an essential factor in drilling operations as it balances the formation pressure and prevents well blowouts..
The load exerted on the BOP handling system by the static weight of the BOP stack. Source: API SPECIFICATION 7K, Drilling and Well Servicing Equipment, Sixth Edition, December 2015. Global Standards..
When the well is in a static condition, the bottomhole pressure is equal to the hydrostatic pressure. When the well is circulating, the bottomhole pressure increases due to the applied surface pressure needed to overcome friction pressures in the piping..
It means that the fast line tension will increase under a dynamic condition; however, the dead line tension will remain the same because it is still in static condition.

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.
