connection gas, mud logging term.

n: the analysis of subsurface formation characteristics, such as lithology, porosity, permeability, and saturation, by indirect methods such as wireline well logging or by direct methods such as mud logging and core analysis.

the analysis of formation character or properties, usually by remote logs.

n: (MWD) 1. directional and other surveying during routine drilling operations to determine the angle and direction by which the wellbore deviates from the vertical. 2. any system of measuring downhole conditions during routine drilling operations.

n: a mothod of measuring parameters downhole and sending the results to surface without interrupting routine drilling operations.a special tool containing sensors,power supply and transmitter is installed as part of BHA (q.v.).the information is transmitted

downhole logging while drilling. “Logging While Drilling” is one form of measurement while drilling" - to differentiate it from mud logging, wireline logging, etc. See Logging While Drilling.

n: a continuous examination of the drilling fluid circulating in the wellbore for the purpose of discovering evidence of oil or gas regardless of the quantities entrained in the fluid. When this service is utilised, a portable mud logging laboratory is set up at the well. Also called mud logging.

n: a record of information derived from examination of drilling fluid and drill bit cuttings. See mud logging.

a record of information on mud or cuttings that are circulated to the surface.

n: an employee of a mud logging company who performs mud logging. mud logging n: the recording of information derived from examination and analysis of formation cuttings made by the bit and of mud circulated out of the hole. A portion of the mud is diverted through a gasdetecting device. Cuttings brought up by the mud are examined under ultraviolet light to detect the presence of oil or gas. Mud logging is often carried out in a portable laboratory set up at the well.

n: the staff that responsible for collecting and analysising the material of mud and debrics.

the person who monitors the mud for hydrocarbon shows, y use of chemical analysis, microscopic examination or instrumentation.

n: the recording of information derived from the examination and analysis of drill ncuttings.this also includes the detection of oil and gas.this work is usually done by a service compony that supplies a portable laboratory on the rig.
