Title (EN) COMPOSITIONS AND METHODS TO RECOVER IRREDUCIBLE WATER FOR ENHANCED FORMATION EVALUATION
(FR) COMPOSITIONS ET PROCÉDÉS POUR RÉCUPÉRER L'EAU IRRÉDUCTIBLE AFIN D'EFFECTUER UNE ÉVALUATION AMÉLIORÉE DES FORMATIONS
Abstract:
(EN) Provided here are compositions and improved methods for recovering portion of irreducible water in a porous rock sample. Compositions used here contain a displacement fluid and a surfactant, and lead to an increased recovery of the irreducible water from the porous rock sample.
(FR) L'invention concerne des compositions et des procédés améliorés pour récupérer l'eau irréductible dans un échantillon de roche poreuse. Les compositions utilisées ici contiennent un fluide de déplacement et un tensioactif, et conduisent à une récupération accrue de l'eau irréductible présente dans l'échantillon de roche poreuse.
