To pull the drill stem out of the wellbore to change the bit, to change from a core barrel to the bit, to run electric logs, to prepare for a drill stem test, to run casing, and so on. Also called trip out, tripping out (TOH).
Industry:Oil & gas
A radioactivity well log used to determine formation porosity. The logging tool bombards the formation with neutrons. When the neutrons strike hydrogen atoms in water or oil, gamma rays are released. Since water or oil exists only in pore spaces, a measurement of the gamma rays indicates formation porosity. See radioactivity well logging.
Industry:Oil & gas
An assistant toolpusher whose duty hours are typically during nighttime hours. Also known as a tourpusher.
Industry:Oil & gas
The electrical resistance offered to the passage of current; the opposite of conductivity.
