摘要:
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.

A method for accelerating start-up for steam assisted gravity drainage operations comprising the steps of: forming a steam-assisted gravity drainage production well pair comprising an injection well and a production well within a formation; beginning a pre-soaking stage by soaking one or both of the wellbores of the well pair with a solvent; beginning a pre-heating stage by heating the wellbores of the well pair; beginning a squeezing stage by injecting steam into the wellbores of the well pair; and beginning steam-assisted gravity drainage production.

A process for utilizing microwaves to heat H2O within a subterranean region wherein the heated H2O contacts heavy oil in the subterranean region to lower the viscosity of the heavy oil and improve production of the heavy oil.

Methods are provided for enhancing recovery of heavy oil from oil sand reservoirs through the creation of subsurface high permeability pathways distributed throughout the oil sand reservoirs. The high permeability pathways may be boreholes that extend through the oil sand reservoir. A portion of the high permeability pathway may be packed with high permeability particulate to provide structural support and allow for high permeability throughout the boreholes. After establishing the high permeability pathways throughout the oil sand reservoir, solvent may be introduced into the oil sand reservoir. The solvent has the beneficial effect of lowering the viscosity of the heavy oil, which aids in the extraction of the heavy oil. Thermal recovery processes and other enhancements may be combined with these methods to aid in reducing the viscosity of the heavy oil. Advantages of these methods include, accelerated hydrocarbon recovery, higher production efficiencies, lower costs, and lower extraction times.

Methods relate to recovering coal bed methane. In-situ heating of coal facilitates desorption and diffusion of the methane for production of the methane through a wellbore. Water within fractures of the coal forms an electrical conduit through which current is passed. The heating relies at least in part on resistivity of the water, which thereby preheats the coal for the recovering of the methane.

Methods and apparatus relate to in situ combustion. Configurations of injection and production wells facilitate the in situ combustion. A first production well disposed in a first oil bearing reservoir is spaced from a second production well disposed in a second oil bearing reservoir separated from the first oil bearing reservoir by a stratum having lower permeability than the first and second oil bearing reservoirs. The stratum isolates one of the first and second production wells from one of the first and second oil bearing reservoirs. In situ combustion through the first oil bearing reservoir generates heat that irradiates into the second oil bearing reservoir to enable producing hydrocarbon with the second production well.
摘要:
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.

A hangtag is provided that is capable of hanging and securing a tool, such as a socket. The hangtag has a body portion having a front surface and a back surface, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The tool supporting mechanism includes first and second legs and a locking finger disposed between the first and second legs. The locking mechanism allows the particular tool to be reattached to the hangtag assembly after it is initially unlocked. This allows the hangtag to function as a storage and organization device for the tool.
