20130153215 | Recovery From A Hydrocarbon Reservoir - Embodiments described herein provide systems and methods for improving production of hydrocarbon resources. A method for improving recovery from a subsurface hydrocarbon reservoir includes drilling a well comprising a horizontal segment through a reservoir interval and installing a pipe string in the horizontal well segment, wherein the pipe string comprises a plurality of screen assemblies. Each of the plurality of screen assemblies is located and a hole is drilled in the pipe string at a portion of the plurality of screen assemblies. Each hole is drilled at a desired orientation to a radial axis of the drill string. | 06-20-2013 |
20130153216 | Recovery From A Hydrocarbon Reservoir - A method and systems for improving recovery from a hydrocarbon reservoir are described. A method includes identifying an interval within the reservoir that comprises a reduced reservoir quality, wherein the interval includes hydrocarbons. A production chamber is formed in a reservoir interval below the interval of reduced reservoir quality, wherein the production chamber is in contact with the interval of reduced reservoir quality. Hydrocarbons are mobilized in the interval of reduced reservoir quality by contact with a mobilizing agent and a pressure is changed within the interval of reduced reservoir quality to allow hydrocarbon flow from the interval of reduced reservoir quality. | 06-20-2013 |
20130199777 | HEATING A HYDROCARBON RESERVOIR - A system and methods are provided for heating a hydrocarbon reservoir, wherein the reservoir includes a reduced oil saturation zone in proximity to a heavy oil zone. The method includes injecting an oxidizing gas into the reduced oil saturation zone and combusting hydrocarbons included within the reduced oil saturation zone. The method also includes determining a level of heating within the heavy oil zone that is conductively heated by combustion of the hydrocarbons within the reduced oil saturation zone, and producing hydrocarbons from the heavy oil zone once a desired level of heating has occurred. | 08-08-2013 |
20130199779 | ENHANCING THE START-UP OF RESOURCE RECOVERY PROCESSES - A method and systems are provided for the enhancement of a start-up of a resource recovery process. The system includes a well pair including a production well at a first elevation and an injection well at a higher elevation. The well pair is configured to force an initial fluid communication between the production well and the injection well to occur at a selected region along a completion of the production well and a completion of the injection well. | 08-08-2013 |
20130199780 | RECOVERY FROM A HYDROCARBON RESERVOIR - A method and systems for using a non-volatile solvent to recover heavy oils are provided. In a method a solvent that includes a non-volatile component is injected into the reservoir. A mobilizing fluid is injected into the reservoir. Fluid is produced from the reservoir, wherein the fluid comprises the solvent, the mobilizing fluid, and the hydrocarbons from the reservoir. | 08-08-2013 |
20130341018 | Recovery From A Subsurface Hydrocarbon Reservoir - Methods and systems for improving recovery from a subsurface hydrocarbon reservoir are described. A method includes drilling a horizontal well in a zone proximate to a contiguous section of cap rock over a reservoir interval. A refrigerant is flowed through the horizontal well to freeze water in the zone, forming a freeze wall in contact with the contiguous section of cap rock. A chamber is formed above the reservoir interval, wherein the chamber includes the contiguous section of cap rock and at least one freeze wall. | 12-26-2013 |
20140083694 | Methods and Systems for Providing Steam - A system is provided for improved steam generation. The system includes at least two steam systems, wherein a wet steam output from a first steam system is passed through a first separator. The first separator configured to separate dry steam from condensate, and a piping connection is configured to blend the condensate with a boiler feed water stream at the inlet of a second steam system. | 03-27-2014 |
20140083706 | Methods and Systems for Providing Steam - A steam system is provided that includes a steam generator including boiler tubes that are modified to form a number of intermediate take-offs for removing water and steam from the boiler tubes. A number of intermediate separators are provided to separate the water and steam at each of the intermediate take-offs. Intermediate couplings are used to inject the water back into the boiler tubes downstream of each of the plurality of intermediate take-offs. | 03-27-2014 |
