摘要： A process for hydraulic fracturing of a subterranean reservoir formation penetrated by a wellbore includes pumping a fracturing fluid or other aqueous fluid which is an aqueous suspension of particles which each comprise an oilfield chemical distributed within an encapsulating matrix of water-insoluble carrier material from the surface via the wellbore and into the reservoir. The encapsulating matrix is chosen so as to provide a delayed release of the oilfield chemical from the particles into surrounding fluid, such that oilfield chemical is liberated from the particles after they have entered the fracture. The encapsulating matrix may be a polymer which is at least partially amorphous, with a glass transition temperature below the reservoir temperature.

摘要： A process of making observations of a subterranean reservoir penetrated by a wellbore uses distinguishable sets of tracer particles and comprises steps of: (i) delivering a plurality of sets of tracer particles to respective subterranean locations via the wellbore, the particles in each set comprising a tracer substance which distinguishes that set form the other sets; (ii) causing or allowing the tracer substances to flow out from the tracer particles whilst the particles are at the respective subterranean locations; (iii) causing or allowing production of fluid out of said reservoir via the wellbore; and (iv) detecting the presence or absence of the tracer substances in the produced fluid. The tracer substances are sufficiently distinguishable from each other to enable a tracer substance detected in the produced fluid to identify the set of tracer particles from which it has come and hence identify the location from which it has come. The process may be used in conjunction with hydraulic fracturing, placing sets of particles at different locations within a fracture and/or in different fractures extending from a single wellbore.

摘要： A method and system are described in which a first composition may be delivered to a target location, which target location may include but is not limited to a location in a wellbore penetrating an earth formation. The first composition is dispersed into a second composition to form an emulsion, where the emulsion is stabilized by particles that are responsive to a magnetic field. The emulsion is used to transport the first composition to the target location where the emulsion is subjected to a magnetic field sufficient to interact with the particles and disrupt the emulsion, and thereby change the viscosity of the composition and/or release the first composition at the target location. In some aspects, the first and second composition may react together upon the release of the first composition at the target location.

摘要： Monitoring of a wellbore which penetrates a reservoir is carried out by providing tracer material at one or more subterranean locations within or proximate the wellbore, so that tracer may enter the flow and be present in flow from the wellbore; repeatedly taking samples from the flow from the wellbore, and analyzing the samples for the presence of tracer, in the vicinity of the wellsite. Taking samples from the flow will generally be done at the surface and may be done by automatic equipment controlled by a programmed computer. The computer may be programmed to take action, such as operating a valve within the well, in response to detection of tracer. Sampling repeatedly and analyzing on site can provide information in something close to real time and thus integrates the use of tracers into an overall process of monitoring and control.

摘要： A method of providing a viscous emulsion at a subterranean location accessible via a wellbore, begins by providing an aqueous/aqueous emulsion comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other. The two phases contain respective solutes which are sufficiently incompatible that they cause phase separation. The dispersed phase is rich in one solute, which may be a thickening polymer, while continuous phase is rich in a second solute, which may comprise surfactant. A hydrophobic liquid is dispersed in this emulsion to become the dispersed phase of a viscous emulsion whose continuous phase is provided by the aqueous/aqueous emulsion. The hydrophobic liquid and the aqueous/aqueous emulsion may be pumped separately down the wellbore to the subterranean location, and allowed to mix there so as to form the viscous emulsion at the subterranean location. On mixing, surfactant from the aqueous/aqueous emulsion may migrate to the oil/water interface, allowing the aqueous phases to become one phase with the result that the emulsion is further thickened by any thickening polymer in its composition. Even more thickening can be achieved by crosslinking the thickening polymer.
摘要翻译：一种在地下位置提供经由井筒的粘性乳液的方法开始于提供包含两种水溶液的水性/水性乳液，所述水性溶液在表面温度和压力下能够以分离的水相共存并与其他。这两个阶段含有各自的溶质，这些溶质足够不相容，导致相分离。分散相富含一种溶质，其可以是增稠聚合物，而连续相富含第二溶质，其可以包含表面活性剂。将疏水性液体分散在该乳液中成为其连续相由水性/水性乳液提供的粘稠乳液的分散相。可以将疏水性液体和水性/水性乳液分别沿着井眼泵送到地下位置，并允许在那里混合，从而在地下位置形成粘性乳液。在混合时，来自水性/水性乳液的表面活性剂可迁移到油/水界面，使水相成为一相，结果乳液进一步被其组合物中的任何增稠聚合物增稠。通过交联增稠聚合物可以获得更多的增稠。
