Embodiment Construction

[0031] It will be appreciated that the various embodiments described herein may be utilized in various orientations, such as oblique, inverted, horizontal, vertical, and in various configurations, without departing from the principles of the present disclosure. The embodiments are described merely as an example of a beneficial application of the principles of the disclosure, and the disclosure is not limited to any specific details of these embodiments.

[0032] exist Figure 1-10 Representatively shown in FIG. 1 is a well system 10 embodying principles of the present disclosure and related methods. in such as figure 1 In the well system 10 shown, the formation 12 contains bitumen or other relatively heavy deposits of heavy hydrocarbons 14 .

[0033] Hydrocarbons 14 need to be recovered, but they are located at depths between about 70 and 140 meters which cannot be achieved by surface mining and SAGD methods. However, it should be clearly understood that formation 12 and hy...

Abstract

Systems and methods for thermal recovery of shallow bitumen using increased permeability inclusions. A method of producing hydrocarbons from a subterranean formation includes the steps of : propagating at least one generally planar inclusion outward from a wellbore into the formation; injecting a fluid into the inclusion, thereby heating the hydrocarbons; and during the injecting step, producing the hydrocarbons from the wellbore. A well system includes at least one generally planar inclusion extending outward from a wellbore into a formation; a fluid injected into the inclusion, hydrocarbons being heated as a result of the injected fluid; and a tubular string through which the hydrocarbons are produced, the tubular string extending to a location in the wellbore below the inclusion, and the hydrocarbons being received into the tubular string at that location.

Description

technical field [0001] The present disclosure generally relates to equipment employed with and operations performed with respect to subterranean wells, and in the embodiments described herein, more particularly provides thermal recovery of shallow bitumen through enhanced permeability inclusions. Background technique [0002] There is a need for a cost-effective method of thermally recovering bitumen from relatively shallow formations such as those found between about 70 and 140 meters depth in the ground. Typically, bitumen can be recovered by surface mining processes down to a depth of about 70 meters, and steam-assisted gravity drainage (SAGD) thermal recovery methods can effectively recover bitumen deposits at depths greater than about 140 meters. [0003] However, mining of bitumen between depths at which both surface mining and SAGD are effective and advantageous is not currently practiced. The depth range of 70 to 140 meters is too deep for conventional surface minin...
