IN-LINE MUD LOGGING METHOD

A method for real-time or near real-time analysis of drilling fluid and/or drill cuttings from a well is applied to the material conveyed from the well to a mud circulation system during a drilling operation. A gamma-ray detector is provided in-line with the mud circulation system. Solids are concen...

Beschreibung
Zusammenfassung:	A method for real-time or near real-time analysis of drilling fluid and/or drill cuttings from a well is applied to the material conveyed from the well to a mud circulation system during a drilling operation. A gamma-ray detector is provided in-line with the mud circulation system. Solids are concentered in a concentrator proximate to the gamma-ray detector. Gamma-ray spectra are detected for gamma-rays emitted from the concentrated solids. The material is removed from the concentrator. Information regarding the gamma-ray spectra representing a time correlated to drilling depth is communicated to a control unit remote from the mud circulation system.
