A fracturing fluid may be introduced into the first zone of the subterranean formation at a rate and pressure sufficient to create or enhance one or more fractures in the subterranean formation. The first zone of the subterranean formation may be isolated from the second zone of the subterranean formation and one or more perforations in the second zone of the subterranean formation may be created or enhanced using the workover tool. | 08-12-2010 |
20100294494 | WATER HEATING APPARATUS FOR CONTINUOUS HEATED WATER FLOW AND METHOD FOR USE IN HYDRAULIC FRACTURING - A method of hydraulic fracturing of an oil producing formation includes the provision of a heating apparatus which is transportable and that has a vessel for containing water. The method contemplates heating the water up to a temperature of about 200° F. (93.3° C.). A water stream of cool or cold water is transmitted from a source to a mixer, the cool water stream being at ambient temperature. The mixer has an inlet that receives cool or cold water from the source and an outlet that enables a discharge of a mix of cool or cold water and the hot water. After mixing in the mixer, the water assumes a temperature that is suitable for mixing with chemicals that are used in the fracturing process, such as a temperature of about 40°-120° F.+ (4.4-48.9° C.+). An outlet discharges a mix of the cool and hot water to surge tanks or to mixing tanks. In the mixing tanks, a proppant and an optional selected chemical or chemicals are added to the water which has been warmed. From the mixing tanks, the water with proppant and optional chemicals is injected into the well for part of the hydraulic fracturing operation. The mixer preferably employs lateral fittings that enable heated water to enter the mixer bore at an acute angle. The mixer can also provide a lateral fitting that exits the mixer bore upstream of the first lateral fitting, the second lateral fitting transmitting water via a conduit such as a hose to the heater. | 11-25-2010 |

20130269935 | TREATING HYDROCARBON FORMATIONS USING HYBRID IN SITU HEAT TREATMENT AND STEAM METHODS - A method for treating a tar sands formation includes providing heated fluid to a first section of the hydrocarbon layer while providing heat to a second section of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. The second section is vertically displaced from the first section. Heat is allowed to transfer from the heaters and heated water to at least a portion of the formation. Fluids are allowed to gravity drain to a third section of the hydrocarbon formation. Fluids are produced from the formation through at least one production well that is located in the third section of the formation. | 10-17-2013 |
20130292114 | Methods For Containment and Improved Recovery in Heated Hydrocarbon Containing Formations By Optimal Placement of Fractures and Production Wells - A method for containing and capturing liquids and gases generated during in situ pyrolysis that migrate through pyrolysis generated or natural fractures includes placing a row of horizontal hydraulic fractures above and below the heated zone and completing production wells within the horizontal hydraulic fractures. The method serves at least two purposes: 1) provides a local zone of weak mechanical strength to blunt the propagation of vertical pyrolysis generated fractures and 2) provides a drainage point for fluids to relieve pressure in the formation and improve recovery. Preferably, the organic-rich rock formation is an oil shale formation. | 11-07-2013 |
20140096959 | ENHANCED HYDROCARBON RECOVERY FROM MULTIPLE WELLS BY STEAM INJECTION OF OIL SAND FORMATIONS - The present invention is a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by steam injection into highly permeable vertical inclusion planes in the oil sand formation, and heating the heavy oil and bitumen, which flow by gravity to the wells. The inclusion is propagated into a portion of the formation having a Skempton's B parameter of greater than 0.95 exp(−0.04 p′)+0.008 p′, where p′ is a mean effective stress in MPa at the depth of the inclusion. The inclusion planes can be propagated from only the central well, or from all wells, being the central well and the periphery wells. The inclusion planes are propagated into the formation to intersect and coalesce to provide hydraulic connection between the central well and the periphery wells. Steam is injected continuously in the central well, and liquids are produced continuously from all wells, whilst maintaining a liquid head over production tubing for steam trap control. By injection of solvents and other gases and controlling the reservoir temperature and pressure, a particular fraction of the in situ hydrocarbon reserve is extracted and water inflow into the heated zone is minimized. | 04-10-2014 |
