Abstract: A liquid additive mixing apparatus is provided that has a plurality of chambers containing additives, as well as a system for mixing the additives. One or more additives are mixed with water to form a mixing fluid. The mixing fluid is placed in a first tank that is fluidly connected to a cement mixing unit. A cementing operation is executed during which the mixing fluid from the first tank is mixed with a cement to form a slurry. A capillary electrophoresis (CE) instrument is employed to monitor at least one additive parameter and detect deviations from a predetermined tolerance for the at least one additive parameter.

Abstract: Methods of treating an aqueous source are described herein that include reducing a concentration of sulfide species in a stream obtained from the aqueous source to form an extraction feed and extracting ions from the extraction feed, or a stream obtained from the extraction feed, using direct aqueous extraction. Other methods describe treating an aqueous source by reducing a concentration of organic species in a stream derived from the aqueous source to form an extraction feed and extracting ions from the extraction feed, or a stream derived from the extraction feed, using direct aqueous extraction. The aqueous source can be an aqueous lithium source.

Abstract: Systems and methods for monitoring a crude oil blending process use nuclear magnetic resonance (NMR) sensors which investigate properties of a plurality of crude oil streams that are mixed together to form a crude oil blend. An NMR sensor is also used to investigate the properties of the crude oil blend. The investigated properties may include viscosity. Resulting determinations may be used to control the input streams so that the output stream meets desired criteria. Additional sensors such as spectroscopy sensors, viscometers, and densitometers may be used in conjunction with the NMR sensors.

Abstract: Methods of treating a subterranean formation penetrated by a wellbore may include injecting a multistage fracturing treatment into the wellbore comprising one or more stages of geopolymer precursor composition containing a geopolymer precursor and an activator, and one or more stages of a spacer fluid; and curing the one or more stages of geopolymer precursor composition. In another aspect, methods of treating a subterranean formation penetrated by a wellbore may include injecting a multistage fracturing treatment into the wellbore that include one or more stages of geopolymer precursor composition, wherein the geopolymer precursor composition includes an emulsion having an oleaginous external phase, and an internal phase comprising one or more surfactants, a geopolymer precursor, and an activator, and one or more stages of a spacer fluid; and curing the one or more stages of geopolymer precursor composition.

Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

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 workflow and fluid analysis system to determine polar concentration and type of a reservoir fluid sample that is collected and analyzed in a downhole environment. Once collected this data can be fed into an advisory tool which can predict the probability of different types of issues that might be encountered in production of reservoir fluids from the reservoir. The workflow and fluid analysis system can also be employed in a surface-located laboratory tool for analysis of reservoir fluids.
