摘要： Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectivity into the well; the shear resistance can be measured in terms of viscosity loss due to shear, and the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

摘要： Beneficiating drilling fluids that comprise low-quality clay and high-quality clay may be performed by adding a polymer and a high-quality clay to a fluid that comprises an aqueous base fluid and a low-quality clay, so as to yield a drilling fluid, wherein the ratio of the low-quality clay to the high-quality clay is about 90:10 to about 80:20.

摘要： A system for producing homogenized oil field gel including a power unit, a control system, a feed tank, a hopper, and a piping assembly that includes inlet and outlet manifolds, centrifugal pumps, and metering devices for filling the feed tank and handling a discharge of oilfield gel. The system further includes a powder hydration component and liquid chemical equipment. The method for producing homogenized oil field gel includes a guar powder procedure including a controlled sequence for starting and stopping a venturi mixer in a hydration unit. The method for producing homogenized oil field gel further includes a liquefied gel concentrate procedure including a metering and chemical injection procedure for mixing a liquefied gel concentrate.

摘要： Disclosed herein are compositions and methods for increasing recovery of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations. Novel emulsions and fracturing fluids are provided. The fracturing fluids convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The fracturing fluids do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations.

摘要： Disclosed are high temperature and high pressure fluid loss additives comprising: a) a humic substance, and b) a tetrapolymer prepared from polymerizing: i) acrylamide (AM), ii) 2-acrylamido-2-methylpropane sulfonic acid (AMPS), iii) 1-allyloxy-2-hydroxypropyl sulfonate, and iv) acrylic acid. The use of such high temperature and high pressure fluid loss additives in water-based drilling fluids in oil-field drilling operations is also disclosed.
