Abstract: An automated system which instantaneously measures the production rates of gas and liquid produced from a liquid saturated core sample to automatically determine the gas-liquid relative permeability of the core sample. An apparatus (110) is provided for collecting fluids produced from the liquid saturated core sample (200) under pressure, instantaneously monitoring the weight of the produced liquid (210) by a sensitive electronic load cell (90), and instantaneously monitoring the volume of the produced gas (220) by a pressure sensor (258). The data is fed to a computer (60) which calculates the gas-liquid relative permeability of the core sample (200).

Abstract: A system and process are provided for converting a hydrocarbon gas to a reformed gas containing hydrogen and carbon monoxide. In accordance with a first embodiment, the system includes a primary combustor, compressor and power turbine. The process is practiced by compressing a feed air in the primary compressor to produce a primary air. The primary air is fed with a primary hydrocarbon gas to the primary combustor, producing a reformed gas that drives the primary power turbine. The primary power turbine is linked to the primary compressor, compressing the feed air in an energy self-sufficient manner. In a second embodiment, the system of the first embodiment further includes a secondary combustor, compressor and power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. A portion of the primary air is also fed with a secondary hydrocarbon gas to the secondary combustor, producing an off-gas that drives the secondary power turbine and compressor to compress a gas in an energy self-sufficient manner. In a third embodiment, the system is substantially the same as the second embodiment, but reconfigures the compressors and power turbines and further includes an auxiliary secondary power turbine. The process is practiced in the same manner as the first embodiment, producing the reformed gas and driving the primary power turbine and compressor. The off-gas is produced in the same manner as the second embodiment to drive the secondary power turbine, but the secondary power turbine drives an auxiliary primary compressor, compressing the feed air ahead of the primary compressor in an energy self-sufficient manner. The off-gas further drives the auxiliary secondary power turbine to provide additional power for alternate power users.

Abstract: Polymer enhanced foam fluid is utilized for completion, workover, and kill operations in wells penetrating subterranean formations. The foam is formed by appropriately adding a gas to an aqueous solution of a substantially noncrosslinked water-soluble polymer and a surfactant. The solution and the foam are substantially free of crosslinking agents. The foam may be generated at the surface or in a wellbore.

Abstract: A process for converting hydrogen sulfide which is contained in a gaseous feed stream to elemental sulfur and hydrogen. In accordance with the process, a gaseous feed stream containing hydrogen sulfide is contacted with a polar organic solvent having a quinone and a complexing agent dissolved therein. The complexing agent must have a pKb value of less than about 13.0. Reaction of the hydrogen sulfide in the gaseous feed stream with quinone results in an increased conversion of quinone to hydroquinone at low reactor temperatures and H2S partial pressures and in increased sulfur recovery. In addition, the presence of a complexing agent increases hydrogen production selectivity in the dehydrogenation of hydroquinone to quinone and hydrogen.

Abstract: A pressure data validation method which measures differential pressure along with measuring the absolute pressure while testing a well. The method uses a differential pressure gauge having a known distance between the two differential pressure measuring gauges, wherein the pressure differential indicates fluid density. During the test, as each absolute pressure reading is taken, a differential pressure reading is also taken and this reading is used to determine the density of the fluid surrounding the gauge at the time of the measurement. Each measurement is compared to previous measurements, and a change in fluid density, and thus a change in the type of fluid, is displayed to indicate that any discontinuity in the pressure display is due to a fluid boundary.

Abstract: A process and composition are provided for permeability reduction in a hydrocarbon-bearing formation to improve hydrocarbon recovery therefrom. The process includes placement of a crosslinked polymer gel in the treatment region preceded by surface preparation of a gelation solution from which the gel is formed. The gelation solution contains a crosslinkable polymer, a transition metal/poly-carboxylate precursor complex and an aqueous solvent. The gel is placed in the treatment region by injecting the gelation solution into a well bore in fluid communication with the formation, activating the gelation solution in situ, displacing the gelation solution into the desired treatment region and gelling the solution to completion forming the permeability-reducing gel in situ. The gelation rate is retarded in a controled manner by adjusting the molar ratio of the poly-carboxylate to transition metal in the precursor complex of the gelation solution.

Abstract: A method for inhibiting inorganic sulfate scale growth in an aqueous fluid present within or produced from a subterranean formation is preformed by contacting the aqueous fluid in situ with a scale inhibitor composition containing two homopolymers in solution within an aqueous liquid medium. The first homopolymer is a polyvinyl sulfonate and the second homopolymer is a polyacrylic acid. The weight ratio of the first homopolymer to second homopolymer is preferably at least about 1:1 and the aqueous fluid being contacted by the composition typically contains a relatively high concentration of precursor ions of inorganic sulfate scale, including scale-forming inorganic cations and scale-forming sulfate anions.
