Industry:Oil & gas
a record of certain electrical characteristics (such as resistivity and conductivity) of formations traversed by the borehole. It is made to identify the formations, determine the nature and amount of fluids they contain, and estimate their depth. Also called an electric log or electric survey.
Industry:Oil & gas
sucker rods that have been broken and separated in a pumping well because of corrosion, improper loading, damaged rods, and so forth.

to pierce the casing wall and cement of a wellbore to provide holes through which formation fluids may enter or to provide holes in the casing so that materials may be introduced into the annulus between the casing and the wall of the borehole. Perforating is accomplished by lowering into the well a perforating gun, or perforator.
Industry:Oil & gas
to temporarily or permanently cease production from a well or to cease further drilling operations.
Industry:Oil & gas
a machine for converting the heat content of fuel into rotary motion that can be used to power other machines. Compare motor.
Industry:Oil & gas
1. a well completion method in which the producing zone or zones are cased through, cemented, and perforated to allow fluid flow into the wellbore. 2. a well completed by this method.
