  Surfactant-stabilized foams for enhanced oil recovery
  Unlike traditional surfactants, "per-fluorinated" surfactants exhibit excellent foam stability in the presence of reservoir oil, but their cost is prohibitive. This patent reveals that only low levels (10%) are needed to achieve foam stability when used in combination with cheaper hydrocarbon surfactants. Thus the benefits of extremely stable gas-blocking foams are achieved without the high surfactant cost.
• US 5,301,539
  Method for improving enhanced recovery of oil using surfactant-stabilized foams.
  Special surfactants are identified that imbibe oil for transport in a sand. This patent teaches the use of surfactant- stabilized foams to control gas flow in an oil reservoir, thus reducing the gas-oil ratio: high gas rates from oil reservoirs inhibits oil production and creates serious facilities problems, especially on off-shore production platforms. Successful field tests have been conducted in Canada to abate solvent breakthrough in a Gas Miscible Flood.
• US 5,060,727

  Oilfield in situ hydrocarbon upgrading process (CAPRI Process) CPTL
  In a reservoir combustion process, catalyst is placed in the annular space of a horizontal producer to partially upgrade draining oil in the reservoir.
• US 6,167,966
  Toe-to-heel oilfield recovery process (water-flooding process) CPTL
  Medium or light oil are produced by injecting water in a vertical injection well and producing from a horizontal well near the top of the reservoir. The process uses a unique configuration of injection and production wells to achieve "gravity-stable" oil and water flow in the reservoir. Besides increasing oil recovery in light oil reservoirs, the process greatly increases the range of oil grades amenable to water-flooding.

  Oilfield enhanced in situ combustion process(P/T control) CPTL
  Steam or produced gas are injected to the toe of the horizontal production well in a THAItm in situ combustion process to control temperature and pressure at the toe. This enables higher safe air injection rates and higher oil production rates
• US 7,493,953
  Oilfield enhanced in situ combustion process (CO2/O2) CPTL
  Co-injection of carbon dioxide and oxygen combines the benefits of combustion with solvent extraction to increase the oil production rate and oil recovery factor in heavy oil or bitumen in situ combustion processes.
• US 7,841,404
  Modified process for hydrocarbon recovery using in situ combustion (HTT) CPTL
  This is a "heel-to-toe" in situ combustion process where air is injected in an isolated vertical section of the horizontal producer. This saves drilling a separate vertical well at remote drill pad: the oil drainage front movement is from the heel to the toe of the horizontal producer through a long tubing.

  Well liner segments for in situ petroleum upgrading and recovery, and method of in situ upgrading and recovery (CAPRI Process) CPTL
  This patent covers a completion design for placing bitumen- cracking catalyst in the annular space of a double horizontal well liner to intercept and upgrade hot draining oil using the heat and hydrogen generated in the combustion process. Upgrading the oil several points API density was achieved when the process was tested in a reservoir.
• CA 2,698,454
  Improved in situ combustion recovery process using a single horizontal well to produce oil and combustion gases to surface. (Multi-THAI) CPTL
  Multiple vertical air injection wells are placed directly above a horizontal producer to increase oil rate several-fold because of greater simultaneous utilization of long horizontal production wells. This is especially beneficial in bitumen reservoirs where initial fluid communication is difficult. The multiple vertical wells could be replaced by a single horizontal well, so the patent also covers the case where oxygen is injected into an upper SAGD well after establishing communication with the producer or as a post-SAGD process to increase the bitumen recovery factor. The use of air combustion instead of steam reduces the energy burden 3-fold because the energy is generated inside the reservoir by burning the heaviest 10% of the oil as fuel. The produced oil has an API gravity of 10.5 (up from 7.0), making it "heavy oil". Sulphur, metals, asphaltenes, and acid number are reduced and shipping requires less diluent. In effect, the bitumen reservoir becomes a heavy oil reservoir, enhancing the reserve valuation

  Low pressure Fischer-Tropsch process (fuel hydrocarbons free of wax) CCC
  A Fischer-Tropsch catalyst is disclosed that converts synthesis gas directly to high- cetane diesel (78). This eliminates the need for hydrocracking waxes produced in traditional FT processes, and opens FT to application in small plants. The economics are greatly enhanced by the elimination of some plant operations and the greater value of retail diesel (retail diesel price versus crude oil price). Alternatively, the process produces 97 % "Wide-cut jet fuel". The process is also a large net water producer which carries value in some jurisdictions.

  Removal of sulfur compounds from a gas stream (Conversion of COS, CS2) CPTL
  This process uses water and an oxygen-containing gas to simultaneously hydrolyze COS and CS2 to H2S and convert H2S to elemental sulfur by "direct oxidation" with low energy consumption.
• US 8,501,135
  Process for the removal of sulfur from a gas stream (Complete H2S removal)
  Complete removal of sulfur compounds from a gas stream is achieved by a direct oxidation process with re-cycling to sulfur species extinction.

  Sorbents for the recovery and stripping of acid gases. ( Stripping CO2 at elevated pressure) CPTL
  CO2 and H2S are recovered with a low- energy solid- state process utilizing an amine composite. Stripping is achieved at elevated pressures, saving compression energy for CO2 transportation. Traditional energy-intensive liquid amine processes strip CO2 with high temperature steam at atmospheric pressure: the CO2 has to be is compressed from atmospheric to 1070 psi. With raw gas at 100 psi, the CO2 is recovered at 300 psi. If the raw gas is >1100 psi, the CO2 is recovered as a liquid, ready for pumping to a pipeline or down-hole.

  (Allowed Patent) Improved hydrocarbon recovery process exploiting multiple induced fractures (Fracture-Floodingth in light tight reservoirs) IORCanada
  This technology solves the problem of fast oil production rate decline in tight multi-fractured reservoirs such as the Bakken. Improved oil recovery is achieved by utilizing alternate induced fractures as injection and production channels. Two parallel nearby wells, that are lined and cemented, are fractured so that the fractures are interlaced. Then one well is used as an injection well and the second well as a production well. Fluid in the injection channels flows laterally through the matrix, increasing reservoir pressure and pushing oil into the production fractures. The fluid can be any gas or liquid, such as produced gas or water. Over 40% oil recovery is achieved from tight rock in 9-years.

  Utilizing dual injection and production tubing and packing to conduct improved hydrocarbon recovery from induced reservoir fractures. IORCanada
  Packers for dual tubings are employed to isolate each fracture. The injection tubing has fractures opposite every second fracture and the other tubing has perforations opposite the other fractures. The process enables simultaneous lateral fluid flow over the entire reservoir, injecting into half the fractures and producing from the other half. The process produces oil at the most favourable rate when applied from the outset, so that the oil viscosity is not increased by the evolution of dissolved gas, as would occur if primary production were conducted initially. Extremely high sustained oil or gas rates are achieved with this process and it can be applied to any reservoir having consolidated rock.
• (Part of above)
  Utilizing a single injection tubing and packer to conduct improved hydrocarbon recovery from induced reservoir fractures. IORCanada
  After the completion of multi-fracturing a well, an inflatable injection tubing packer is placed just before the last fracture in a multi-fractured horizontal well. Injected fluid, such as produced gas, is injected and fills the fracture, The fluid assists with maintaining pressure during drawdown and sweeps oil laterally from that fracture to the next fracture in the direction of the heel. When the fluid breaks through, the packer is deflated and the tubing is drawn back one fracture towards the heel. The packer is re-inflated and the above process repeated until, sequentially, the entire reservoir of swept. Then the reservoir pressure is drawn down, giving a final surge of oil. The most common fluids to use are produced gas and water, since they are free, with the former preferred. However the use of a miscible gas, such as CO2 would increase the oil recovery factor. An advantage the this process is that any old de-pressured multi-fractured well can be re-entered and re-energized for a low completion cost. As opposed to using the cyclic gas injection/production process, this process is continuous and provides reservoir sweep with an oil recovery factor of at least 40%. This process and it can be applied to any reservoir having consolidated rock.
• CA 2,835,592
  Method of producing oil from induced fractures using a single wellbore and multiple-channel tubing. IORCanada
  As an alternative to employing packers that accommodate two tubings, it is simpler to employ only a single tubing. A single tubing with inflatable packers is placed in the multi-fractured well, so that packers are located on both sides of each fracture. Inside the tubing there are several distinct channels. One channel is perforated to every second fracture ( the injection channel) and another is perforated to the other fractures (the production channel). Fluid in the injection channel enters its contiguous fracture and sweeps oil laterally to the fracture contiguous to the production channel, and hence to the surface. A third channel may optionally be employed to inject blocking fluid into the wellbore space between the fractures if there is concern that the EOR fluid will bypass around the isolation packers. Also, a fourth channel could be used to maintain full inflation of the packers. Extremely high sustained oil or gas rates are achieved with this process and it can be applied to any reservoir having consolidated rock.

  Method for recovering hydrocarbons from a subterranean reservoir IORCanada
  This is a process for improving the recovery of oil from un-consolidated reservoirs. When these are fractured from horizontal wells it is not possible to keep back the sand. This patent discloses that the problem is solved by drilling the horizontal well in the basement rock and fracturing from there. In the part of the fracture within the basement, the resin-coated sand pellets are held firmly and are able to exclude reservoir sand. The fracturing injectant fluidizes the reservoir and enhances oil production. The process could be used with steam and heavy oil in a cyclic manner or by drive between the fractures.
