  • Well Treatment
    Publication number: 20070254814
    Abstract: This invention provides a method of controlling water in a subterranean formation, said method comprising contacting said formation with a water control treatment agent which comprises an organosilane in an amount effective to reduce the water permeability of at least part of said formation. At the same time, any decrease in the overall hydrocarbon (e.g. oil) permeability of said formation is preferably minimised. The invention further provides a method of plugging or sealing a subterranean formation.

  • Well Treatment
    Publication number: 20070204990
    Abstract: The present invention provides a method for the treatment of a subterranean formation which contains sand particles, said method comprising contacting said formation with a material capable of increasing the residual matrix strength of said particulate fine whereby to reduce or prevent their migration whilst minimising any decrease in their permeability. Preferred materials include organosilanes and enzyme systems.

  • Methods detecting, characterising and monitoring hydrocarbon reservoirs
    Publication number: 20060154306
    Abstract: The present invention relates to a method of detecting, characterizing or monitoring a hydrocarbon source, which method comprises the genotypic analysis of a sample for the presence of one or more thermophilic or extemophilic microorganisms and in particular to the generation of microbiological profiles of samples and to the comparison of these profiles with profiles from reference samples. Also provided are oligonucleotides for use in said method.

  • Method of well treatment
    Publication number: 20050115710
    Abstract: The invention provides a method of well treatment comprising introducing into the matrix surrounding a hydrocarbon well bore hole an emulsion the discontinuous phase of which comprises a non-polymerizable, water or oil miscible liquid carrier, a polymerizable monomer and a thermally activated polymerization initiator, said monomer constituting from 2 to 40% wt. of said discontinuous phase.
