Embodiment Construction

[0025] While the invention is susceptible to various modifications and alternative forms, the drawings illustrate by way of example specific embodiments of the invention and are described in detail herein. The drawings may not be to scale. It should be understood, however, that the drawings and detailed description are not intended to limit the invention to the particular forms disclosed, but on the contrary, the invention is to cover all modifications, equivalents, and alternatives insofar as they are It only needs to fall within the design concept and protection scope of the present invention, and the scope of the present invention is defined by the appended claims.

[0026] The following description is generally directed to systems and methods for treating hydrocarbon-bearing formations. These formations are processed to produce higher quality hydrocarbon products, hydrogen, and other products.

[0027] "Hydrocarbon" is basically defined as a substance whose molecules are...

Abstract

A method for treating a hydrocarbon containing formation (122) is described. The method may include providing' heat from one or more heaters (128) to at least a portion of the formation. At least one heater may be located in at least one wellbore (120) in the formation. At least one wellbore may be sized, at least in part, based on a determination of formation expansion caused by heating of the formation so that formation expansion caused by heating of the formation is not sufficient to cause substantial deformation of one or more heaters in the sized wellbores. The ratio of the outside diameter of a heater to the inside diameter of a wellbore may be less than about 0.75. In certain embodiments, heat may be allowed to transfer from the one or more heaters to a part of the formation. In some embodiments, a mixture may be produced from the formation.

Description

technical field [0001] The present invention generally relates to a method and system for producing hydrocarbons, hydrogen, and / or other products from a hydrocarbon-bearing formation. Certain embodiments of the present invention relate to solutions for preventing deformation of heater boreholes during in situ treatment of hydrocarbon containing formations. Background technique [0002] Hydrocarbons extracted from subsurface rock formations, such as sedimentary rocks, are commonly used as energy sources, raw materials, and consumer goods. A number of methods have been proposed to more efficiently extract, process and / or utilize available hydrocarbon energy sources due to several considerations: the availability of hydrocarbon energy sources is becoming increasingly depleted and the The overall quality level of recovered hydrocarbons is declining. In situ processing methods may be used to recover hydrocarbons from subterranean formations. The chemical and / or physical proper...
