Abstract: A sensor including first and second electrodes can be used to determine the concentration of at least one chemical constituent in a fluid sample under test. The electrodes can be disposed in the fluid sample and a predetermined voltage can be applied to a first electrode. The voltage can cause a current to flow between the first and second electrodes through the sample, the current dependent on the concentration of the chemical constituent in the fluid sample. A sense resistor is coupled to the first electrode such that the current flowing between the electrodes flows through the sense resistor. A processor electrically isolated from the electrodes can receive data signals indicative of the voltage drop across the sense resistor and the voltage applied at the first electrode. The received signals can be used to determine the concentration of the constituent in the fluid sample.

Abstract: Invertible latices suitable for use in enhanced oil recovery are formed by adding a first inversion surfactant and a second inversion surfactant to a water-in-oil latex comprising about 15 wt % to 50 wt % of a water soluble polymer having a net ionic charge. The first inversion surfactant has a hydrophilic/lipophilic balance of about 15 to 35 and an ionic charge that is the opposite of the net ionic charge of the polymer. The second inversion surfactant has a hydrophilic/lipophilic balance of between about 8 and 20. The invertible latices are diluted in a single step to provide dilute latices having 10,000 ppm or less polymer solids.

Abstract: A method of inhibiting scale in a subterranean formation comprises pretreating the subterranean formation with a polyquaternary amine that serves as a squeeze life extension (SLE) agent, and then introducing a scale inhibitor pill into the subterranean formation, wherein the scale inhibitor pill includes one or more scale inhibitor compositions. For example, the polyquaternary amine may be a polymer having up to 5 quaternary amine centers, but is preferably a nonpolymeric diquaternary amine having a molecular weight of from 250 to 500. One such example is 1,3-propandiaminium, 2-hydroxy-N,N,N,N?,N?,N?-hexamethyl-, dichloride. The SLE agent is preferably introduced into the formation in a brine solution having a concentration from 0.1 to 20 weight percent.

Abstract: Disclosed are compositions derived of mixtures of choline ion salts (typically choline chloride) in aqueous solution with suspended particulates of sparingly soluble borate minerals or with alkali or alkaline earth borate salts, boric acid and its ester derivatives and salts, or other aqueous soluble borate forms. These compositions are useful as cross-linkers for polysaccharides and other biopolymers and particularly as used in subterranean treatment fluids for completion and stimulation of oil and gas wells. Advantages of the compositions are the combination into a single package of the properties of clay stabilizing actives (choline ion) and crosslinking actives (borates, etc.), in relatively high concentrations, and these compositions are easy to handle, being stable and pumpable at low temperatures, and with attractive environmental profiles. Also disclosed are the analogous choline solutions mixed with metallic cross-linking ions know in the art such as Zr+, Ti4+, Al3+, & Fe3+.
