Title (EN) ESTIMATION OF FORMATION PROPERTIES BASED ON BOREHOLE FLUID AND DRILLING LOGS
(FR) ESTIMATION DE PROPRIÉTÉS D'UNE FORMATION BASÉE SUR DU FLUIDE DE TROU DE FORAGE ET DES RAPPORTS DE FORAGE
Abstract:
(EN) A method of estimating one or more properties of an earth formation includes disposing a carrier in a borehole in an earth formation as part of an energy industry operation, receiving borehole fluid from the borehole, estimating at least one property of the borehole fluid associated with one or more intervals along the borehole, and generating a mud log that indicates values of the at least one property at the one or more intervals, the at least one property including at least one of gas content and cuttings content. The method also includes estimating, by a processor, one or more properties of the formation based on the mud log, the one or more properties selected from at least one of lithology, permeability, total organic carbon and brittleness, and controlling one or more operational parameters of the energy industry operation based on the one or more properties of the formation.
(FR) L'invention concerne un procédé d'estimation d'une ou plusieurs propriétés d'une formation terrestre, consistant à disposer un support dans un trou de forage dans une formation terrestre en tant que partie d'une opération de l'industrie de l'énergie, recevoir du fluide de forage à partir du trou de forage, estimer au moins une propriété du fluide de forage associé à un ou plusieurs intervalles le long du trou de forage et produire une diagraphie de boue qui indique des valeurs de la propriété au niveau du ou des intervalles, ladite ou lesdites propriétés comprenant la teneur en gaz et/ou la teneur en déblais. Le procédé consiste également à estimer, par un processeur, une ou plusieurs propriétés de la formation sur la base de la diagraphie de boue, la ou les propriétés étant choisie(s) parmi au moins la lithologie, la perméabilité, le carbone organique total et la fragilité, et régler un ou plusieurs paramètres de fonctionnement de l'opération de l'industrie de l'énergie sur la base de ladite ou desdites propriétés de la formation.
