Title (EN) OILFIELD MONITORING OF SUBTERRANEAN POLYMER SOLUTION
(FR) SURVEILLANCE DE CHAMP DE PÉTROLE DE SOLUTION POLYMÈRE SOUTERRAINE
Abstract:
(EN) Aqueous liquid which has been in contact with a subterranean geological formation, especially a hydrocarbon reservoir, is examined in order to detect or measure viscosifying polymer therein, by flowing a sample of the liquid through a constriction thereby causing extensional flow and alignment of any polymer molecules with the flow, and examining the solution for birefringence of aligned polymer molecules. The amount of birefringence is determined from intensity of light which has passed through the solution relative to intensity of the light source.
(FR) L'invention concerne un liquide aqueux qui a été en contact avec une formation géologique souterraine, en particulier un réservoir d'hydrocarbures, et qui est examiné pour détecter ou mesurer un polymère améliorant la viscosité à l'intérieur de ce dernier, par écoulement d'un échantillon du liquide à travers un étranglement, provoquant ainsi un écoulement d'extension et un alignement de molécules polymères quelconques avec l'écoulement, et par examen de la solution pour la biréfringence de molécules polymères alignées. L'amplitude de biréfringence est déterminée à partir de l'intensité de lumière qui est passée à travers la solution par rapport à l'intensité de la source de lumière.
