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: Shale inhibitor additives, wellbore fluids comprising said additives, and methods using said fluids control hydration in wellbores disposed within swellable subterranean formations. The wellbore fluids contain aqueous base fluids. the shale inhibition additives. and natural biopolymeric viscosifiers. and optional encapsulating polymer agents. wherein the shale inhibition additives include amine-based shale inhibition agents. The methods circulate the wellbore fluids into the wellbores and/or maintain triamine-based shale inhibition agents of the wellbore fluids at concentrations of at least 50% by weight. based on total weights of the shale inhibition additives during multiple circulations of the wellbore fluids in the wellbores.

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: 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.

Abstract: Systems and methods presented herein relate to real-time analysis of production chemicals at wellsites utilizing capillary electrophoresis (CE) analysis of produced water in-situ and in substantially real-time to determine the effectiveness and efficiency of production chemicals injected into wells. For example. systems and methods presented herein include CE equipment configured to receive sample fluids from production fluids extracted from various locations of wellsites, and to perform CE analysis to generate data relating to one or more fluid properties of the sample fluids. The systems and methods presented herein also include an analysis and control system configured to detect and quantify individual components of production chemicals injected into wells of the wellsites based at least in part on the data relating to the one or more fluid properties of the sample fluids.

Abstract: Nuclear magnetic resonance (NMR) relaxation and/or diffusion measurements are used to deduce fluid compositional information such as a chain-length distribution, which may then be used to predict the true boiling points (TBP) of a sample of a complex hydrocarbon fluid mixture, such as a crude oil. The NMR measurements may be considered a fast and portable proxy measurement in estimating fluid TBP distributions in lieu of distillation methods, or the simulated distillation by gas chromatography.

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: The current application discloses methods and systems to analyze on-site and in real-time or quasi real-time the composition of the well fluid before or during use or disposition. The method is based on capillary electrophoresis (CE) and does not require the addition of tracers into the well fluid or additive. Based on the significance of each additive on the well fluid properties, it can be decided to determine the concentration of all additives or only one or a limited number of the additives present in the fluid, and the concentrations can be adjusted as needed to reach the desired target concentration(s).
