v: 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.

n: See trip.

n: an electric log in which current flow in the logging tool was dispersed through the mud in the wellbore prior to entering the formation. As a result, formation resistivity measurements were often inaccurate. These logs are no longer used.

abbr: electric log;used in drilling reports.

n: see electric well log.

n: when make the plan for a well ,draw the bit record of reference well on the electric chart for comparison each other

n: the process of running an electric log. See electric well log.

n: Electric logs run on a wire line to obtain information concerning the porosity, permeability, density, and/or fluid content of the formations drilled. The drilling-fluid characteristics may need to be altered to obtain good logs.



a method of rock and fluid identification or evaluation that began in 1927. The first log was run by Conrad Schlumberger.

n: a record of certain electrical charac-teristics (such as resistivity and conductivity) of forma-tions traversed by the borehole. It is made to identify the forma-tions, determine the nature and amount of fluids they contain, and estimate their depth. Also called an electric log or electric survey.

n: trade name for focused electric log that investigates the flushed zone.
