Apparatus, systems, and methods for a modular heating unit that may be adapted to be inline with a pipeline. The unit includes a base member having a main inlet pipe, a header, and pipes connecting the main inlet pipe with the header. A combustion chamber is positioned within the pipes. One or more heat exchangers are connected to the header. The heat exchangers each having a top surface, bottom surface, plurality of fins, inlet ring, inlet port, outlet ring, and outlet port. The modular heating unit includes external inlet and outlet pipes. A first flow path enables fluid to flow from the header into the one or more heat exchangers. An exit flow path connected to the external outlet pipe connects the one or more heat exchangers to an exit port with a portion of the exit flow path being positioned above the one or more heat exchangers.

A system and method of producing oil is provided. The system includes a support module that provides air, water and fuel to a well. A steam generator is fluidly coupled to the support module to receive the air, water and fuel. The steam generator includes an injector having a plurality of tubes. The tubes have an outer surface with an oxidation catalyst thereon. The steam generator is configured to divide the supplied air and direct a first portion through the tubes. A second portion of the supplied air is mixed with supplied fuel and directed over the outside of the tubes. The air and fuel is burned in a combustor and water is sprayed on the combustion gases to produce steam. The steam and combustion gases are directed in the direction of the oil reservoir.

A tight-shale oil production tool includes a combustor operable to generate an aqueous-phase nitric acid, combustion products.

An acoustic actuator for scale removal and prevention in a wellbore is described herein. For example, a system can include a tubing string deployed downhole in a wellbore. A downhole tool can be coupled to the tubing string. An acoustic actuator can be coupled to the tubing string and positioned proximate to the downhole tool. The acoustic actuator can generate an acoustic signal that can vibrate the tubing string to generate a fluidic disturbance in downhole fluid within the tubing string for removing contaminants from, or preventing formation of contaminants, on the downhole tool.

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.
