the process of cutting a vertical, cylindrical sample of the formations encountered as a well is drilled.
Industry:Oil & gas
a systematic recording of data, such as a driller’s log, mud log, electrical well log, or radioactivity log. Many different logs are run in wells to discern various characteristics of downhole formation.
Industry:Oil & gas
1. the flat portion machined on the base of the bit shank that meets the shoulder of the drill collar and serves to form a pressure-tight seal between the bit and the drill collar. 2. the portion of the box end or the pin end of a tool joint; the two shoulders meet when the tool joint is connected and form a pressure-tight seal.
Industry:Oil & gas
a bit that does not drill out the center portion of the hole, but allows this center portion (the core) to pass through the round opening in the center of the bit and into the core barrel.
Industry:Oil & gas
to run any of the various logs used to ascertain downhole information about a well.
Industry:Oil & gas
1. to close the valves on a well so that it stops producing. 2. to close in a well in which a kick has occurred.
Industry:Oil & gas
any of a variety of complex chemical or electrochemical processes, such as rust, by which metal is destroyed through reaction with its environment.
Industry:Oil & gas
any of several electrical, acoustical, mechanical, or radioactivity devices that are used to measure and record certain characteristics or events that occur in a well that has been or is being drilled.
Industry:Oil & gas
the pressure at the bottom of a well when the surface valves on the well are completely closed. It is caused by formation fluids at the bottom of the well.
Industry:Oil & gas
