  • Patent number: 11921255
    Abstract: Method for modelling a reservoir including receiving a data set relating to one or more wells within a reservoir, processing the data set to identify one or more fractures extending from the one or more wells into the reservoir, categorizing the one or more fractures as principal fractures or secondary fractures, identifying a near well high permeability region for each of the one or more wells, generating a gridded fracture plane of the one or more wells, determining a fracture permeability region, assembling the gridded fracture plane, the fracture permeability regions, and the near well high permeability region for each of the one or more wells, and generating a three-dimensional reservoir model based on the assembled gridded fracture plane for each of the plurality of predetermined depths, the fracture permeability regions, and the near well high permeability region for each of the one or more wells.

  • Patent number: 11225859
    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.

  • Patent number: 10851632
    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.

  • Patent number: 10597579
    Abstract: The present invention relates to a method for reducing solvent retention in ES-SAGD process so as to increase process economics wherein an anti-retention agent is injected into the reservoir to decrease solvent retention in the reservoir. The anti-retention agent can be made pre-injection or can form in situ, and comprises an agent in which the solvent is readily soluble, such that the solvent partitions into the foam, colloidal dispersion, or gel, and out of the condensed water or steam, and away from the reservoir rock.

  • Patent number: 9082269
    Abstract: Locating devices and systems providing haptic tactile feedback are disclosed. In one embodiment, a locator includes a haptic handle configured to provide directional signals through an operator's sense of touch to aid in locating and tracing a buried conductor or other object such as a pipe or cable.

  • Publication number: 20140190689
    Abstract: The present invention relates to a novel method of maintaining a steady and/or proper water-gas ratio for the wet in situ combustion process for oil recovery. In particular, the method comprises mixing water with a foaming agent, or some other colloid capable of generating foam, in addition to gas. The foam carries the water through heated reservoirs more efficiently and prevents separation from the gas. As such, more heat can be scavenged, thus an increased amount of steam is generated and transferred to the oil to increase its recovery.
