    摘要: To purify a dimethyl sulphoxide (DMSO), it is placed in contact with a plurality of cation exchange resins at least one of which is a resin of sulphonic type in —SO3H or —SO3NH4 form, it being possible for the other or others to be of chelating type. The DMSO thus obtained has an iron cation content lower than 1 ppb and a sodium cation content lower than 2 ppb.

    摘要: The present invention relates to the development of tracer fluids, more generally, that of aqueous liquids, intended to be injected under pressure in an oil reservoir, for example from an injection well up to a production well.The object of the invention is to propose a new method of study of a solid medium, i.e. an oil reservoir, by diffusion of a liquid (i.e. injection waters) containing tracers, through said solid medium, which is simple to implement and economical and which remedies the drawbacks of the known tracers for injection waters of oil reservoirs.This method essentially consisting of injecting, in this solid medium, an injection liquid comprising a nanoparticle-based tracer having average dimensions comprised between 20 and 200 nm, detectable by means of one or several S signals at dilutions of less than or equal to 10−7, adapted to form a stable colloidal suspension in a saline medium, at least a portion of which is constituted of a core and a coating provided with an adjustable hydrophilic-lipophilic balance (HLB) and comprising at least one organic and/or organosilicon component; recovering the liquid having diffused; and analyzing this liquid having diffused to measure the quantity of tracer by detection of the signal or signals S.
