  • Patent number: 10815761
    Abstract: A process for producing hydrocarbons from a subterranean hydrocarbon-bearing reservoir includes injecting a gas, at a pressure below a minimum miscibility pressure, into the reservoir through an injection well extending into the reservoir to form a gas zone in the reservoir. The gas injection pressure is suitable to provide a differential pressure between a bottom-hole production well pressure at a horizontal multi-lateral production well extending into the reservoir, and the gas injection pressure to facilitate sweeping the hydrocarbons toward the production well prior to gas breakthrough at the production well.

  • Patent number: 10718193
    Abstract: 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.

  • Patent number: 10519362
    Abstract: A method for residual oil recovery from oil reservoirs, and diagnostic tests for determining its efficiency using a single well are described. The method includes injecting oil into a well in a reservoir that has been previously waterflooded or an oil reservoir or zone of an oil reservoir which contains immobile oil at the time of discovery, and extracting the oil by waterflooding the charged zones by placing the injection well in production. The target zone from which oil is recovered may be increased by following injection of oil with injection of water to push an oil bank which grows in volume as a function of distance of propagation, because of the effect of waterflooding on residual oil. The well may then be placed in production and the oil bank volume will continue to increase in volume as it returns to the well, again because of the waterflooding effect. The oil bank is then produced at the surface.

  • Patent number: 10145227
    Abstract: An embodiment in accordance with the present invention includes a method for estimating the permeability of fractured rock formations from the analysis of a slow fluid pressure wave, which is generated by pressurization of a borehole. Wave propagation in the rock is recorded with TFI™. Poroelastic theory is used to estimate the permeability from the measured wave speed. The present invention offers the opportunity of measuring the reservoir-scale permeability of fractured rock, because the method relies on imaging a wave, which propagates through a large rock volume, on the order of kilometers in size. Traditional methods yield permeability for much smaller rock volumes: well logging tools only measure permeability in the vicinity of a borehole. Pressure transient testing accesses larger rock volumes; however, these volumes are much smaller than for the proposed method, particularly in low-permeability rock formations.

  • Patent number: 9784082
    Abstract: 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. Lateral bores divert from lengths of injector and producer wells along where extending in a horizontal direction. These bores pass upward through the formation to intersect the stratum and provide an array of fluid flow paths through the stratum. In a side direction perpendicular to the horizontal direction of the wells, the lateral bores from the injector well pass through the stratum inside of where the lateral bores from the producer well pass through stratum. Fluid communication established by the bores limits counter-current flow through the bores in processes that rely on techniques such as gravity drainage.

  • Patent number: 9650876
    Abstract: A method of recovering resources from a resource bearing formation includes selectively injecting a fluid into the resource bearing formation through one or more injector wells, extracting a resource from the resource bearing formation through one or more production wells, receiving at a sweep pattern controller, an input from each of the one or more production wells indicating an amount of the resource extracted over a period of time, determining, in the sweep pattern controller, an adjusted sweep pattern for the formation that substantially equalizes production from each of the one or more production wells, and signaling each of the one or more injector wells, from the sweep pattern controller, to selectively inject the fluid to establish the adjusted sweep pattern in the formation.

  • Patent number: 9587480
    Abstract: Techniques for recovering hydrocarbons, such as heavy hydrocarbons or bitumen, from a cellar region below a horizontal production well can include providing a cellar well section that extends from the horizontal production well into the cellar region. The horizontal production well can be part of a Steam-Assisted Gravity Drainage (SAGD) in situ recovery system, which forms a hydrocarbon depleted region and a hydrocarbon bearing cellar region. The cellar region includes hydrocarbons that have been pre-heated by SAGD operations. One or more cellar well sections are provided from the SAGD production well to extend into the cellar region, in order to form a branched production well. A pressurizing gas can be injected into the hydrocarbon depleted region from a SAGD injection well, in order to provide sufficient pressure to promote production of pre-heated hydrocarbons from the cellar region through the cellar well section.

  • Patent number: 9574433
    Abstract: A method and system determines the performance index of subterranean rock. A performance index is determined for subterranean rock of an area. The area includes a well. A time period is determined during producing the well. The performance index is also determined from data of the time period from the equation PI=(q/dd)*(cum./GPI). The term PI is the performance index, and the term q is the average daily rate of the well for the time period. The term dd is the average drawdown per day of the well for the time period, and the term cum. is the cumulative production of the well for the time period. The term GPI is the gross perforated interval of the well for the time period.

  • Patent number: 9477009
    Abstract: The invention is a method of evaluating a recovery potential for hydrocarbons contained in a fractured reservoir, using an enhanced recovery technique. Characteristic reservoir data, data obtained from well test results and data relative to the development conditions are acquired. A pressure gradient related to the flow of a fluid injected to improve recovery is then estimated from the previously acquired data. A recovery coefficient is calculated for the hydrocarbons initially in place in matrix blocks by estimating water saturation for a state of equilibrium of the matrix blocks. Finally, the oil recovery time under the effect of the fluid circulation in fractures is estimated by determining the required for the matrix blocks to change from the initial state to a state of equilibrium.

    Abstract: A method for heating a production fluid in a wellbore. The method can include heating, using a packer fluid, a working fluid flowing through a first medium disposed in a first section of the wellbore, where the first medium transfers heat from the packer fluid to the working fluid. The method can also include circulating the working fluid into a second section of the wellbore through a second medium, where the second medium transfers heat from the working fluid to the production fluid. The method can further include returning the working fluid to the first section of the wellbore through the first medium.
