Definitions for "ECD"
Electron Capture Dissociation
Electron capture detector, used in gas chromatography.
Electron Capture Detector. A type of gas chromatographic detector which is sensitive to halogenated hydrocarbons and other molecules capable of easily gaining an electron. Electron capture is not generally used for hydrocarbon detection.
abbreviation: equivalent circulating density.
equivalent circulating density. the increase in bottomhole pressure expressed as an increase in pressure that occurs only when mud is being circulated. Because of friction in the annulus as the mud is pumped, bottomhole pressure is slightly, but significantly, higher than when the mud is not being pumped. ECD is calculated by dividing the annular pressure loss by 0.052, dividing that by true vertical depth, and adding the result to the mud weight.
Equivalent Circulating Density. This is the drilling fluid density that would be required to produce the same effective borehole pressure resulting from the combination of fluid density, circulatory pressure and cuttings loading of the drilling fluid in the wellbore.
