tail cement
Oil & gas; Drilling
The last cement system pumped during primary cementing. The tail cement covers the lower sections of the well, especially planned completion intervals, and is typically more dense ...
potassium ion
Oil & gas; Drilling
The ion of potassium, K + . There are tests used to monitor high (>5000 mg/L) or low ( + ) concentration in water-base muds. The test for high concentration, as specified by the ...
reverse circulation
Oil & gas; Drilling
The intentional pumping of wellbore fluids down the annulus and back up through the drillpipe. This is the opposite of the normal direction of fluid circulation in a wellbore. ...
geosteering
Oil & gas; Drilling
The intentional directional control of a well based on the results of downhole geological logging measurements rather than three-dimensional targets in space, usually to keep a ...
directional drilling
Oil & gas; Drilling
The intentional deviation of a wellbore from the path it would naturally take. This is accomplished through the use of whipstocks, bottomhole assembly (BHA) configurations, ...
direct-indicating viscometer
