Abstract: A process for producing petroleum from subterranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a production well. The process involves injecting via the injection well into the formation an aqueous solution of sulfomethylated lignosulfonate salt as a sacrificial agent to inhibit the deposition of surfactant and/or polymer on the reservoir matrix. The process may best be carried out by injecting the sulfomethylated lignosulfonates into the formation through the injection well mixed with either a polymer, a surfactant solution and/or a micellar dispersion. This mixture would then be followed by a drive fluid such as water to push the chemicals to the production well.

Abstract: A solvent refining unit treats medium sour charge oil with a furfural solvent in a refining tower to yield raffinate and extract mix. The furfural is recovered from the raffinate and from the extract mix and returned to the refining tower. A system controlling the refining unit includes a gravity analyzer, a flash point temperature analyzer, a sulfur analyzer, a refractometer and viscosity analyzers; all analyzing the medium sour charge oil and providing corresponding signals, sensors sense the flow rates of the charge oil and the furfural flowing into the refining tower and the temperature of the extract mix and provide corresponding signals. One of the flow rates of the medium sour charge oil and the furfural flow rates is controlled in accordance with the signals from all the analyzers, the refractometer and all the sensors, while the other flow rate of the medium sour charge oil and the furfural flow rates is constant.

Abstract: Alkylaromatic charge hydrocarbons such as toluene are steam dealkylated in the presence of catalyst which typically contains oxides of nickel, chromium, and potassium on an activated high-purity alumina. It is a feature of this invention that the high-purity alumina is activated by calcining followed by addition thereto of alkaline earth metal such as calcium or magnesium. A test is disclosed according to which it may be determined which high-purity aluminas are suitable for use.

Abstract: Fatty alkyl succinate ester and succinimide modified copolymers of ethylene and an alpha-olefin, such as an ethylene-propylene copolymer, are useful as shear stable viscosity index (VI) improvers, dispersants and pour point depressants in lubricating oils. Especially useful is the succinate ester of mixtures of primary n-alkanols containing about 12 to about 18 carbon atoms and the N-(3-dimethylaminopropyl) succinimide derivative of the copolymer of ethylene and an alpha-olefin, such as an ethylene-propylene copolymer. This succinate ester-succinimide derivative is prepared by reacting the copolymer in an aromatic solvent with maleic anhydride in the presence of a free radical initiator, then esterifying the anhydride with a fatty alcohol or mixtures thereof in the presence of an acidic catalyst and finally converting any unreacted anhydride and half esters to the succinimide by reaction with a polyamine containing a primary amine. Additive concentrates containing 5 to 30 wt.

Abstract: Formation fluid is activated by a neutron source. A cluster of three gamma ray detectors provides count rate data with the count values varying among the three detectors as dictated by the geometry of the cluster and the angle of displacement of the activated fluid between the time of neutron bombardment and that of gamma ray detection. Measurements at different time intervals following the activation of the fluid may also be interpreted in terms of the speed of horizontal fluid flow past the borehole.
