Systems and methods are disclosed that may include providing a wellhead gas burner to burn wellhead gas produced from a wellhead to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may include a pressure regulator and an expansion chamber that permit the wellhead gas burner to continuously operate and accommodate wellhead gas pressure fluctuations. The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional propane/diesel gas burner system configured as a supplemental heat source. The wellhead gas burner may also be mounted to a mobile superheater truck.

A system and method for enhanced hydrocarbon recovery utilizing steam. The system may include a high pressure water pump supplying pressurized water to a heat exchanger within a combustion heater to form supercritical steam that is provided to a reservoir. The combustion heater may be a surface mounted heater or a downhole steam generator.

The branching of fractures in shale formations surrounding a wellbore can be enhanced so that more rock surface is exposed in the formation and more hydrocarbon resources can be recovered using smaller quantities of fracturing fluids. The branching of the fractures can be enhanced by establishing a substantially static sub-threshold fluid pressure in a well in a geological formation, and generating a pressure pulse in the well such that the pressure pulse combined with the substantially static sub-threshold fluid pressure forms a plurality of fractures in the geological formation. An arc jet insertable into a passage in the geological formation and having an electric arc channel can be used to generate the pressure pulse.

A method for stimulating a well includes mixing at least one thermochemical with fracturing fluid to create a fracturing fluid mixture, injecting the fracturing fluid mixture into the well, creating an exothermic reaction with the fracturing fluid mixture, generating a pressure pulse in the well from the exothermic reaction, and fracturing a formation around the well with pressure from the pressure pulse and a hydraulic pressure source.

Methods of extracting methane from coal beds using a plasma energy source configured to generate acoustic, electrical, mechanical and hydrodynamic compressive and rarefactive stresses by the action of periodic short pulses, produced by an explosion of a calibrated conductor of a source of oscillations placed in the working interval of a well.

One method includes position an antenna inside a wellbore in a location corresponding to a formation where near wellbore damage occurs; wherein the wellbore extends from a surface of a hydrocarbon reservoir downward into the subterranean structure of the hydrocarbon reservoir; transmitting an electromagnetic (EM) wave to the antenna; and irradiating, from the antenna, at least a portion of the EM wave at the formation, wherein the portion of the EM wave removes the near wellbore damage at the formation.

This application relates to systems and methods for stimulating hydrocarbon bearing rock formations using a downhole hybrid tool for discharging a fracturing solution to a wellbore in the formation and for delivering an output laser beams to the rock formation.

An example laser tool is configured to operate within a wellbore of a hydrocarbon-bearing rock formation. The laser tool includes one or more optical transmission media. The one or more optical transmission media are part of an optical path originating at a laser generator configured to generate a laser beam having an axis. The one or more optical transmission media are for passing the laser beam. The laser tool includes an optical element that is part of the optical path. The optical element is for receiving the laser beam from the one or more optical transmission media and for output to the hydrocarbon-bearing rock formation. The laser tool includes a color applicator head for discharging one or more coloring agents to a surface in the wellbore in a path of the laser beam.

The invention relates to the field of oil production, in particular, to a method for extracting high-viscosity, heavy oil or bitumen. The equipment package includes a ground frequency generator combined with a power and control unit and 2 downhole instruments. One downhole device is an electrohydraulic downhole device with a plasma discharger (hereinafter referred to as DEHDPD) of directional action, designed to create microcracks in the oil reservoir. The second well device has a long length (up to 50 meters) and consists of alternately alternating microwave and acoustic emitters (hereinafter DDMWAE), which simultaneously or alternately affect the oil reservoir. Downhole devices are lowered into the well, their movement along the horizontal well and power supply to them is carried out using a umbilical cable. Oil production from the well is carried out using a pump fixed between the umbilical cable and the DDMWAE. The use of the invention makes it possible to increase the efficiency and environmental friendliness of extraction of high-viscosity, heavy oil or bitumen from a horizontal well due to the complex application of acoustic and electromagnetic wave technologies.

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. A water stream of cool or cold water is transmitted from a source to a manifold, the cool or cold water stream being at ambient temperature. The manifold 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 manifold, 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 or cold and hot water to tanks. In the tanks, a proppant and an optional selected chemical or chemicals are added to the water which has been warmed. From the tanks, the water with proppant and optional chemicals is injected into the well for part of the hydraulic fracturing operation.
