Disclosed is an improved system and method for carrying out the petroleum coking process. The improvements provide for recovery of gaseous hydrocarbons from operational units and use of the recovered gaseous hydrocarbons in place of steam during the coking process and during the stripping of volatile compounds from the coke drums.

Systems and methods for delayed coking

A method of producing heavy oil by first injecting water and sulfur hexafluoride molecules into a region. The method then introduces electromagnetic waves such as microwaves and/or radio frequencies into the region at a frequency sufficient to excite the water and the sulfur hexafluoride molecules and increase the temperature of at least a portion of the water and sulfur hexafluoride molecules within the region to produce heated water and sulfur hexafluoride molecules. At least a portion of the heavy oil is heated in the region by contact with the heated water and sulfur hexafluoride molecules to produce heated heavy oil. The heated heavy oil is then produced.

Heavy oil recovery using SF6 and RF heating

A process for utilizing microwaves to heat HO within a subterranean region wherein the heated HO contacts heavy oil in the subterranean region to lower the viscosity of the heavy oil and improve production of the heavy oil.

Process for enhanced production of heavy oil using microwaves

The present invention provides a method of producing upgraded hydrocarbons in-situ from a production well. The method begins by operating a subsurface recovery of hydrocarbons with a production well. An RF absorbent material is heated by at least one RF emitter and used as a heated RF absorbent material, which in turn heats the hydrocarbons to be produced. Hydrocarbons are upgraded in-situ and then produced from the production well.

Simultaneous conversion and recovery of bitumen using RF

A process for utilizing microwaves to heat solvent within a subterranean region wherein the heated solvent, vapor, contacts heavy oil in the subterranean region to lower the viscosity of the heavy oil and improve production of the heavy oil.

A process for utilizing microwaves to heat HO and sulfur hexafluoride within a subterranean region wherein the heated HO and sulfur hexafluoride contacts heavy oil in the subterranean region to lower the viscosity of the heavy oil and improve production of the heavy oil.

A method for preheating a formation prior to beginning steam assisted gravity drainage production. The method proceeds by forming a steam assisted gravity drainage production well pair within a formation. A preheating stage is then begun by injecting an activator into the formation. The preheating stage is then accomplished by exciting the activator with radio frequencies. This is followed by beginning the steam assisted gravity drainage operation.

Accelerating the start-up phase for a steam assisted gravity drainage operation using radio frequency or microwave radiation

Methods and apparatus relate to processes and systems that introduce microwaves into mixtures containing hydrocarbons. The microwaves cause heating of the hydrocarbons in order to upgrade the hydrocarbons. Such upgrading occurs after recovering the hydrocarbons from within a formation and results in lowering viscosity of the hydrocarbons to enable transportation of the hydrocarbons to offsite locations, such as a refinery.

Wellhead hydrocarbon upgrading using microwaves

A method for heating heavy oil inside a production well. The method raises the subsurface temperature of heavy oil by utilizing an activator that has been injected below the surface. The activator is then excited with a generated microwave frequency such that the excited activator heats the heavy oil.

In-situ upgrading of heavy crude oil in a production well using radio frequency or microwave radiation and a catalyst

A method of mixing a catalyst with a heavy oil to create a heavy oil/catalyst mixture. This is followed by combining the heavy oil/catalyst mixture with supercritical water to form light hydrocarbon products and heavy hydrocarbon products. By doing so the light hydrocarbon products can be separated into a gaseous top product, an upgraded liquid hydrocarbon product and a water phase.
