Publication number: 20120073810Abstract: Methods and apparatus relate to recovery of in situ upgraded hydrocarbons by injecting steam and hydrogen into a reservoir containing the hydrocarbons. A mixture output generated as water is vaporized by direct contact with flow from fuel-rich combustion provides the steam and hydrogen. The steam heats the hydrocarbons facilitating flow of the hydrocarbons and reaction of the hydrogen with the hydrocarbons to enable hydroprocessing prior to recovery of the hydrocarbons to surface.Type: ApplicationFiled: September 21, 2011Publication date: March 29, 2012Applicant: ConocoPhillips CompanyInventors: Scott Macadam, James P. Seaba, Wayne Reid Dreher, JR., Joe D. Allison

Patent number: 8118095Abstract: Methods and systems relate to in situ combustion utilizing configurations of injection and production wells to facilitate the in situ combustion. The wells define vertically deviated lengths that have different orientations from one another. Further, heating processes such as resistive heating and cyclic steam stimulation may take place in one or both of the injection and production wells to precondition a reservoir prior to the in situ combustion.Type: GrantFiled: February 17, 2010Date of Patent: February 21, 2012Assignee: ConocoPhillips CompanyInventors: Partha S. Sarathi, Wayne Reid Dreher, Jr., Thomas J. Wheeler, Wendell P. Menard

Publication number: 20110232903Abstract: Methods are provided for enhancing recovery of heavy oil from oil sand reservoirs through the creation of subsurface high permeability pathways distributed throughout the oil sand reservoirs. The high permeability pathways may be boreholes that extend through the oil sand reservoir. A portion of the high permeability pathway may be packed with high permeability particulate to provide structural support and allow for high permeability throughout the boreholes. After establishing the high permeability pathways throughout the oil sand reservoir, solvent may be introduced into the oil sand reservoir. The solvent has the beneficial effect of lowering the viscosity of the heavy oil, which aids in the extraction of the heavy oil. Thermal recovery processes and other enhancements may be combined with these methods to aid in reducing the viscosity of the heavy oil. Advantages of these methods include, accelerated hydrocarbon recovery, higher production efficiencies, lower costs, and lower extraction times.Type: ApplicationFiled: March 11, 2011Publication date: September 29, 2011Applicant: CONOCOPHILLIPS COMPANYInventors: Wayne Reid Dreher, JR., Tawfik Nasr, Wendell Menard, Thomas J.

Patent number: 7909093Abstract: Methods and apparatus relate to in situ combustion. Configurations of injection and production wells facilitate the in situ combustion. A first production well disposed in a first oil bearing reservoir is spaced from a second production well disposed in a second oil bearing reservoir separated from the first oil bearing reservoir by a stratum having lower permeability than the first and second oil bearing reservoirs. The stratum isolates one of the first and second production wells from one of the first and second oil bearing reservoirs. In situ combustion through the first oil bearing reservoir generates heat that irradiates into the second oil bearing reservoir to enable producing hydrocarbon with the second production well.Type: GrantFiled: January 15, 2009Date of Patent: March 22, 2011Assignee: ConocoPhillips CompanyInventors: David Andrew Brown, Wayne Reid Dreher, Jr., Thomas J. Wheeler, Wendell Peter Menard

Publication number: 20110011582Abstract: Methods and apparatus relate to in situ combustion. Configurations of the injection and production wells facilitate the in situ combustion. Utilizing wet combustion for some embodiments promotes heat displacement for hydrocarbon recovery with procedures in which one or more of the production and injection wells are configured with lengths deviated from vertical. In some embodiments for either dry or wet combustion, at least the production wells define intake lengths deviated from vertical and that are disposed at staged levels within a formation. Each of the productions wells during the in situ combustion allow for recovery of hydrocarbons through gravity drainage. Vertical separation between the intake lengths of the production wells enables differentiated and efficient removal of combustion gasses and the hydrocarbons.Type: ApplicationFiled: July 16, 2010Publication date: January 20, 2011Applicant: ConocoPhillips CompanyInventors: Partha S. Sarathi, Wayne Reid Dreher, JR., Riley Bryan Needham, Abhishek Dutta

Patent number: 7793720Abstract: Methods and apparatus relate to controlling location of inflow into a production well during in situ combustion. The production well includes intervals closable to the inflow at identified times. Once a combustion front from the in situ combustion passes one of the intervals, a blockage conveyed from surface into the production well forms a barrier to the inflow at the interval that has been passed by the combustion front. An example of the blockage includes a cement plug delivered through coiled tubing into the production well, which may include production tubing that defines the intervals based on at least two consecutive alternating lengths of solid wall sections and slotted or perforated sections of the production tubing.Type: GrantFiled: December 4, 2008Date of Patent: September 14, 2010Assignee: ConocoPhillips CompanyInventors: Wayne Reid Dreher, Jr., Wendell Peter Menard

Publication number: 20100206555Abstract: Methods and systems relate to recovering hydrocarbons from within formations in which hydrocarbon bearing reservoirs are separated from one another by a fluid flow obstructing natural stratum. Relative to the reservoirs, the stratum inhibits or blocks vertical fluid flow within the formation. Drilled bores arranged to intersect the stratum provide an array of fluid flow paths through the stratum. Fluid communication established by the drilled bores enables production utilizing a producer borehole deviated from vertical and processes that rely on techniques such as gravity drainage through the fluid flow paths and/or injection through the fluid flow paths.Type: ApplicationFiled: February 19, 2010Publication date: August 19, 2010Applicant: CONOCOPHILLIPS COMPANYInventors: Wendell Peter Menard, Wayne Reid Dreher, JR., John L.
