    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.

    Abstract: A method of fluid testing includes pressurizing a fluid testing system, disposed at a subterranean location under high pressure compared to a surface pressure, to achieve a desired pressure differential between the high pressure and an internal pressure of the fluid testing system. The fluid testing system includes a capillary electrophoresis system and one or more test fluid reservoirs. The method also includes directing test fluid from the one or more test fluid reservoirs into capillaries to condition the capillaries. The method further includes directing sample fluid into the capillaries for testing while at the subterranean location.

    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.

    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.
