Title (EN) DYNAMICALLY DETERMINING A ROCK WETTABILITY ALTERATION
(FR) DÉTERMINATION DYNAMIQUE D’UNE MODIFICATION DE MOUILLABILITÉ DE ROCHE
Abstract:
(EN) Techniques for determining a rock wettability alteration include circulating a first brine fluid into a test cell that includes a rock sample and a hydrocarbon fluid disposed on a surface of the rock sample, the first brine fluid having a property at a first value; contacting the rock sample and the hydrocarbon fluid with the first brine fluid; measuring a first contact angle between the rock sample and the hydrocarbon fluid in contact with the first brine fluid; at least partially displacing the first brine fluid with a second brine fluid in the test cell, the second brine fluid having the property at a second value; contacting the rock sample and the hydrocarbon fluid with the second brine fluid; measuring a second contact angle between the rock sample and the hydrocarbon fluid in contact with the second brine fluid; and determining a wettability alteration of the rock sample based on at least one of the measured first or second contact angles.
(FR) La présente invention concerne des techniques de détermination d’une modification de mouillabilité de roche qui comprennent la circulation d’un premier fluide de saumure dans une cellule d’essai qui comprend un échantillon de roche et un fluide d’hydrocarbure disposé sur une surface de l’échantillon de roche, le premier fluide de saumure ayant une propriété à une première valeur ; la mise en contact de l’échantillon de roche et du fluide d’hydrocarbure avec le premier fluide de saumure ; la mesure d’un premier angle de contact entre l’échantillon de roche et le fluide d’hydrocarbure en contact avec le premier fluide de saumure ; le déplacement au moins partiel du premier fluide de saumure avec un deuxième fluide de saumure dans la cellule d’essai, le deuxième fluide de saumure ayant la propriété à une deuxième valeur ; la mise en contact de l’échantillon de roche et du fluide d’hydrocarbure avec le deuxième fluide de saumure ; la mesure d’un deuxième angle de contact entre l’échantillon de roche et le fluide d’hydrocarbure en contact avec le deuxième fluide de saumure ; et la détermination d’une modification de mouillabilité de l’échantillon de roche sur la base d’au moins l’un des premier ou deuxième angles de contact mesurés.
