tool joint
Oil & gas; Drilling
The enlarged and threaded ends of joints of drillpipe. These components are fabricated separately from the pipe body and welded onto the pipe at a manufacturing facility. The tool ...
drilling procedure
Oil & gas; Drilling
The engineering plan for constructing the wellbore. The plan includes well geometries, casing programs, mud considerations, well control concerns, initial bit selections, offset ...
contact time
Oil & gas; Drilling
The elapsed time required for a specific fluid to pass a designated depth or point in the annulus during pumping operations. Contact time is normally used as a design criterion ...
cycle time
Oil & gas; Drilling
The elapsed time for mud to circulate from the suction pit, down the wellbore and back to surface. Cycle time allows the mud engineer to catch "in" and "out" samples that ...
equivalent circulating density
Oil & gas; Drilling
The effective density exerted by a circulating fluid against the formation that takes into account the pressure drop in the annulus above the point being considered. The ECD is ...
internal phase
Oil & gas; Drilling
The discontinuous phase of an emulsion, the dispersed droplets of emulsified fluid.
inclination
Oil & gas; Drilling
The deviation from vertical, irrespective of compass direction, expressed in degrees. Inclination is measured initially with a pendulum mechanism, and confirmed with MWD ...
