  • Solvents and NCG-co-injection with tapered pressure
    Patent number: 10648308
    Abstract: A variation of expanding solvent steam assisted gravity drainage (ES-SAGD) production of heavy oil wherein steam and hydrocarbon solvent are co-injected into a heavy oil reservoir and water, hydrocarbon solvent and heavy oil are produced by gravity drainage until the steam chamber is well developed or until oil recovery reaches about 20-30% of oil in place. At that time, the wells are switched to a lateral sweep using non-condensible gas (NSG) and steam co-injection, where more hydrocarbon solvent is recovered than is recovered with ES-SAGD used alone and where the cumulative steam to oil ratio is reduced over using -ES-SAGD alone.
    Type: Grant
    Filed: May 1, 2018
    Date of Patent: May 12, 2020
    Assignee: ConocoPhillips Company
    Inventors: Bo Chen, Thomas James Wheeler, Pradeep Ananth Govind
  • Thermal conditioning of fishbone well configurations
    Patent number: 10370949
    Abstract: The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. Fishbone multilateral wells are combined with SAGD, effectively expanding steam coverage, but the fishbones are preheated to mitigate plugging problems, with e.g., resistive heating, EM heating or chemical heating.

    Assignee: CONOCOPHILLIPS COMPANY
    Inventors: Sergei A. Filatyev, Pradeep Ananth Govind, Thomas J. Wheeler
