Patent number: 10718193Abstract: Methods and systems produce petroleum products from a formation by a steam assisted process followed by an in situ combustion process. The steam assisted process utilizes an injector and first producer to form a steam chamber within the formation as the products are recovered. The in situ combustion then starts by injecting an oxidant into the formation and ignition of residual products. A combustion front advances toward a second producer that may be offset in a lateral direction from the first producer. Heat and pressure from the in situ combustion sweeps the products ahead of the combustion front to the second producer for recovery.Type: GrantFiled: August 22, 2013Date of Patent: July 21, 2020Assignee: ConocoPhillips CompanyInventors: Daniel Ray Sultenfuss, Wayne Reid Dreher, Jr.

Patent number: 8978755Abstract: The method begins by forming a gravity drainage production well pair within a formation comprising an injection well and a production well. The pre-soaking stage begins by soaking at least one of the wellbores of the well pair with a solvent, wherein the solvent does not include water. The pre-heating stage begins by heating the soaked wellbore of the well pair to produce a vapor. The squeezing stage begins by introducing the vapor into the soaked wellbore of the well pair, and can thus overlap with the pre-heating stage. The gravity drainage production begins after the squeezing stage, once the wells are in thermal communication and the heavy oil can drain to the lower well.Type: GrantFiled: September 13, 2011Date of Patent: March 17, 2015Assignees: ConocoPhillips Company, Harris CorporationInventors: Daniel R. Sultenfuss, Wayne Reid Dreher, Jr., Thomas J. Wheeler, Jr., Francis E. Parsche, Mark A. Trautman

Patent number: 8967282Abstract: Heavy oil recovery from oil sand reservoirs is enhanced 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: GrantFiled: March 11, 2011Date of Patent: March 3, 2015Assignee: ConocoPhillips CompanyInventors: Wayne Reid Dreher, Jr., Tawfik Nasr, Wendell Menard, Thomas J.

Patent number: 8353340Abstract: 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: GrantFiled: July 16, 2010Date of Patent: January 15, 2013Assignee: ConocoPhillips CompanyInventors: Partha S.

Patent number: 8240381Abstract: 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: GrantFiled: February 19, 2010Date of Patent: August 14, 2012Assignee: ConocoPhillips CompanyInventors: Wendell Peter Menard, Wayne Reid Dreher, Jr., John L.

Publication number: 20120085533Abstract: A method of producing hydrocarbons from a well. The method begins by injecting steam into a well. The bitumen in the formation is then heated with the injected steam, followed by ceasing the injection of steam into the well and then by soaking the bitumen with the injected steam and collecting the heated oil. Steam that has condensed is revaporized by directing RF/MW radiation to the steam allowing for more bitumen to be produced without injecting more steam. In addition, some of the steam could become superheated, wherein the temperature of the superheated steam is greater than the temperature of the steam. The bitumen is heated by the revaporized steam and the superheated steam, followed by soaking the bitumen with the revaporized steam and the superheated steam. Hydrocarbons are then produced from the well.Type: ApplicationFiled: September 15, 2011Publication date: April 12, 2012Applicants: Harris Corporation, ConocoPhillips CompanyInventors: Maxine Jones Madison, Wayne Reid Dreher, JR., Francis Eugene Parsche, Mark Alan Trautman

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.
