  • Method for determining the extent of recovery of materials injected into oil wells or subsurface formations during oil and gas exploration and production
    Patent number: 7032662
    Abstract: Disclosed is a method of determining the extent of recovery of materials injected into oil wells or subsurface formations. The method includes injection of one or more tracers into an oil well or into a formation. Included in the method are the steps of introducing a material of interest into the oil well or into the subsurface formation associated with the bore of the oil well; introducing a tracer into the oil well or into the subsurface formation associated with the bore of the oil well; recovering from the oil well a production fluid, analyzing the production fluid for a concentration of the chemical tracer present in the production fluid; and calculating the amount of material of interest recovered from the oil well using the concentration of the chemical tracer present in the production fluid as a basis for the calculation.
    Type: Grant
    Filed: November 12, 2003
    Date of Patent: April 25, 2006
    Assignee: Core Laboratories LP
    Inventors: Scott Malone, Earuch Broacha, Don Shaw, Tom Hampton

  • Method for determining the extent of recovery of materials injected into oil wells during oil and gas exploration and production
    Patent number: 6659175
    Abstract: Disclosed is a method of determining the extent of recovery of materials injected into a oil well comprising the steps of: a) preparing a material to be injected into an oil well; b) admixing therewith a chemical tracer compound at a predetermined concentration; c) injecting the admixture into an oil well; d) recovering from the oil well a production fluid; e) analyzing the production fluid for the concentration of the chemical tracer present in the production fluid; and f) calculating the amount of admixture recovered from the oil well using the concentration of the chemical tracer present in the production fluid as a basis for the calculation. Fluorinated benzoic acids are disclosed as a preferred tracer.
