Quantum chemical calculations have been performed on the potential energy surfaces of the two title molecules. The calculations have located the two lowest energy conformations for each molecule. For all four structures, centrifugal distortion constants and chlorine nuclear quadrupole coupling tensor components have been calculated. Analyses of the experimental rotational spectra have yielded the identification of only one conformer for each molecule. These conformers have spectroscopic constants closely matching those of the calculated lowest energy conformers. The chlorine nuclear quadrupole coupling tensor components of the title molecules have been compared with those for propionyl chloride and perfluoropropionyl chloride. © 2012 Elsevier B.V.

Oilfield Review | Year: 2012

Microbes have a long history in the oil and gas industry. New molecular analysis methods, coupled with increased knowledge of microbe identity and chemistry, have led to advances in combating microbiologically influenced corrosion and reservoir damage. Scientists are also using these advances to develop new methods for microbiologically enhanced oil recovery and bioremediation. Source

We report the first structural study of pentanoyl chloride. Vapor above a sample of pentanoyl chloride was mixed with a supersonic expansion of argon gas. Once in this state a chirped pulse Fourier transform microwave spectrometer was used to obtain pure rotational spectra for the target compound between 8 GHz and 16 GHz. Within this experiment two conformers were detected. In both cases rotational constants, quartic centrifugal distortion constants and chlorine nuclear electric quadrupole coupling tensors were obtained for the first time. Quantum chemical calculations have provided structures with rotational constants closely matching the experimental values. The values of the chlorine nuclear quadrupole coupling tensor are compared to those of other acyl chlorides and are consistent with a standard acyl chloride Cl35 χzz value of -59(1) MHz. © 2012 Elsevier B.V.

A method of microbial enhanced oil recovery from a wellbore in an oil-bearing formation that includes injecting water into the oil-bearing formation via a tubing string in the wellbore and introducing oxygen into the oil-bearing formation for consumption by microbes in the oil-bearing formation. The oxygen introduction includes delivering the oxygen into the oil-bearing formation without having the introduced oxygen contact the walls of the tubing string and without having the introduced oxygen contact the injected water within the tubing string while the injected water is in the tubing string.

A method of recovering oil from a formation that includes the use of surfactants at low concentrations. The surfactant may be an oleophilic surfactant. The method may include conditioning an oil recovery system to inhibit microbes that could consume the oleophilic surfactant. A method that determines the concentration of a surfactant that is sufficient to change the interfacial tension between oil and water in a near well bore area of an injection well in a formation but does not require changing the interfacial tension between oil and water outside the near well bore area.
