Abstract: The present disclosure generally relates to harvesting geothermal energy from mature and near end-of-life oil and gas reservoirs that have been subjected to secondary oil recovery steam processes like steam-assisted gravity drainage (SAGD), steamflood, etc. The geothermal potential of these mature SAGD reservoirs can be used to generate green electricity thus reducing the greenhouse gas (GHG) footprint of the oil production. Lateral spacing of injectors and producers, with closing of unused members of a well-pair for energy recovery is described.

Abstract: A method and system in which foams are used (instead of, or in addition to, NCG) to maintain pressure in a mature chamber during blowdown operations of a SAGD process or other enhanced oil recovery process. The foam occupies the depleted void space within the mature chamber after injection ceases, maintaining pressure, and improving blowdown performance. This use of the foam in the method and system also improves the performance of less mature chambers that are being operated at higher pressure adjacent to the mature chamber in blowdown. Foaming agents, such as metal carbonates, bicarbonates, and hydroxides, surfactants or any other colloidal foams, aerosols, hydrosols, emulsions or dispersions can be utilized. The method and system can be utilized in conjunction with other known art, such as heat scavenging in the chamber, or enhanced oil recovery utilizing foams, to displace oil in the chamber.

Abstract: 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.

Abstract: Thermal recovery of oils is improved by capturing waste heat from a depleted steam chamber using steam plus foam and an optional gas to carry low quality steam deep into the chamber where the waste heat converts water to steam in situ. Thus, overall steam generation needs and thus costs are reduced.

Abstract: Described herein are methods for accelerating the start-up in SAGD type processes wherein the volume between the injector and the producer is preheated utilizing open-holes drilled between wells. The recovery of hydrocarbons is also improved due to a viscous fluid drive in the open-holes during SAGD operations.

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.

Abstract: A method of characterizing a subterranean formation using a plurality of seismic acquisitions includes obtaining a first seismic acquisition of the subterranean formation, wherein the first seismic acquisition is a baseline survey. Injecting a gas fluid into the subterranean formation, wherein the gas fluid at least partially fills a portion of a fracture network of the subterranean formation. Obtaining a second seismic acquisition of the subterranean formation. Calculating a time-lapse difference in the plurality of seismic acquisitions.

Abstract: Methods and systems produce petroleum products by insulating a thermal hydrocarbon recovery process from heat loss to surrounding areas of a formation utilizing an insulating composition including a non-gaseous phase component introduced into the reservoir that is different from water and insoluble in the hydrocarbons. The insulating composition may be disposed in the reservoir adjacent to where the heat loss is desired to be limited. In addition, the insulating composition may be disposed in a thief zone and may also be from an agent activated to form the composition at such desired locations by selecting activation dependent on at least one of temperature, time delay and oil saturation.

Abstract: A particularly effective well configuration that can be used for single well steam assisted gravity drainage (SW-SAGD) wherein steam flashing through production slots is prevented by including passive inflow control devices (ICDs) or active interval control valves in the completion. A thermal packer separates the injection and production segments of a horizontal well having a toe and a heel, and the ICDs can be evenly spaced or can decrease towards the heel. The cumulative steam to oil ratio (CSOR) of the SW-SAGD well is thus lowered, as compared to the same well without passive flow control devices or active interval control valves.
