Patent number: 9845668Abstract: Methods and systems relate to recovering hydrocarbons with an injection well placed at a bottom of a reservoir some horizontal distance from a producer, such that the injection well and producer may both be in a common horizontal plane. For some embodiments, the process includes co-injection of steam with a non-condensable gas, such as methane, ethane, propane, carbon dioxide, combustion products and combinations thereof. The non-condensable gas provides additional solution gas drive while the location of the injection well beside, instead of above, the producer increases production time before a steam chamber reaches a top of the reservoir, increasing thermal and recovery efficiency of the process.Type: GrantFiled: June 6, 2013Date of Patent: December 19, 2017Assignee: ConocoPhillips CompanyInventors: Kate M.

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.
