  • Patent number: 10421897
    Abstract: This method is designed to facilitate the well treatment with the possibilities for non-uniform/heterogeneous proppant placement in the extended and branched fractures produced by hydraulic fracturing. The essence of the method is to inject a proppant-bearing gel into the wellbore drilled into a productive formation. The low-viscosity fracturing fluid is injected into the wellbore together with the gel fluid (simultaneously or in turns). The method also provides for the injection of gas into the proppant-bearing gel and/or the low-viscosity fluid. The gas can be injected upstream of the junction point, at the junction point, or downstream of the junction point of the flows of the proppant-bearing gel and the low-viscosity fluid. The method further provides for the division of the gel fluid into the separate agglomerates with their subsequent injection into the fractures in the subterranean formation to form the proppant structures in the fracture.

  • Patent number: 10240082
    Abstract: The disclosure claimed herein relates to well systems for various fluids production, in particular, for production of fluids from hydrocarbon-containing formations using hydraulic fracturing process. According to the proposed method, injecting into well of fracturing fluid not containing proppant is performed to form a fracture in the formation, after which fracturing fluid is injected into the wellbore in pulse mode; the pulse mode provides at least one pulse of injecting fracturing fluid containing proppant, and at least one pulse of proppant-free fluid. Also, methods for fluid production and injection are proposed. Methods for fluids production, injection and recovery using hydraulic fracturing method are proposed. The proposed method increase the well lifetime due to reduced fluid flow impact on fracture walls and proppant clusters.

  • Patent number: 9976417
    Abstract: A method improves the capability for testing a fluid sample, e.g. testing a reservoir sample of hydrocarbon fluid. The methodology comprises positioning a capillary electrophoresis system within an enclosed chamber system. The enclosed chamber system preserves the desired downhole reservoir conditions during testing of the reservoir sample. In some applications, the reservoir sample is divided into a plurality of capillaries of the capillary electrophoresis system to enable testing of the reservoir sample with different types of detectors in one capillary electrophoresis system. The method can also be applied to depressurized reservoir samples.

  • Patent number: 9869624
    Abstract: An apparatus (and method) for characterizing interfacial tension between a non-wetting phase fluid and a wetting phase fluid of a slug flow employs a capillary structure that is configured to contain a slug of the non-wetting phase fluid of the slug flow. The slug has a leading edge meniscus and a trailing edge meniscus, and the capillary structure has a venturi-like section. A pressure sensor is configured to measure differential pressure between first and second locations of the capillary structure. The first location is disposed upstream of the leading edge meniscus of the slug with the leading edge meniscus of the slug contained within the venturi-like section. The second location is disposed downstream of the trailing edge meniscus of the slug. Data processing means is configured to derive a measure of interfacial tension based upon the differential pressure measured by the pressure sensor and, optionally, geometry of the capillary structure.

  • Publication number: 20150355068
    Abstract: A methodology and system determine properties of a sample substance, such as a liquid/foam used to control sweep homogeneity problems in an earth formation. The methodology and system utilize a core of formation simulation material placed in a container. An injection system is coupled to the container and enables placement of both the sample substance and an injection fluid into the container. The injection fluid is injected under pressure and moves the sample substance through the core. A data acquisition system is employed to measure parameters such as pressure differentials along the core as the sample substance propagates through the formation simulation material. The pressure differentials may be evaluated over time by the data acquisition system to determine fluid breakthrough properties of the sample substance.

  • Publication number: 20150204177
    Abstract: A technique facilitates treatment of a subterranean formation. A proppant and a proppant carrier fluid are delivered to a subterranean location for treatment of the formation. At the subterranean location, heterogeneities of proppant structures are generated with the proppant and the proppant carrier fluid. The heterogeneous proppant structures are then transported into the subterranean formation to improve conductivity.
