Problems solved by technology

[0006] However, disadvantageously, under this prior art method, the residence time of the oil in the interstitial space containing such catalyst is very short due to the very short vertical path resulting to drain the fluid (oil) into the porous liner, And the gas and liquid space velocity (Liquid Hourly Space Velocity; LHSV) will be very high

Embodiment Construction

[0060] figure 1 Shown is a schematic diagram of an in-situ hydrocarbon recovery system 2 for improved recovery of hydrocarbons from a hydrocarbon-bearing formation 1 utilizing several elongated well liner segments 10 of the present invention within its horizontal wellbore 3 .

[0061]This hydrocarbon recovery system 2 is adapted to direct hydrocarbons, in particular viscous oil 15 discharged from the hydrocarbon formation 1 during the process of this hydrocarbon recovery system 2, through the catalyst-filled interstitial space 12 within each well liner segment 10, for subsequent recovery to the surface 13.

[0062] Illustrated are several well liner segments 10 of the present invention, each of which is twistably coupled to an adjacent other well liner segment 10 so as to form a well liner segment for use in an in situ hydrocarbon recovery process as shown in figure 1 Well liner in 6.

[0063] In operation, oil 15 heated by in situ combustion or alternatively by steam assis...

Abstract

A well liner segment for use in hydrocarbon recovery processes. An elongate, typically cylindrical outer liner member, and an inner elongate liner member concentrically located therewithin is provided. Hydrocarbon upgrading catalyst is provided in the interstitial space between the two members. The outer liner members may be threadably coupled together. A slidable seal is provided between the outer liner and the inner liner to accommodated differential thermal growth between the two liners. A process for use of well liner segments having hydrocarbon upgrader catalyst pre- installed therein, is also provided, as is a method for manufacture of a well liner segment.

Description

technical field [0001] The present invention relates to horizontal well liners and, more particularly, to well liner segments that permit in-situ upgrading of hydrocarbons during recovery from subterranean reservoirs, and to a method of manufacturing said well liner segments method, and involves a process of using these horizontal well segments for in-situ upgrading and recovery. Background technique [0002] Oil upgrading catalysts (such as, manufactured by Akzo Chemie Nederaland bv Amsterdam and identified as Ketjenefine TM A standard hydrotreating / hydrodesulfurization (HDS) catalyst of 742-1,3AQ) has been used in a prior art oilfield in situ hydrocarbon upgrading process of the type described in US Pat. No. 6,412,557. [0003] Specifically, U.S. Patent No. 6,412,557 describes the use of this known hydrotreating catalyst for upgrading and removing heavy oil from The process by which oil is produced from a (bitumen) formation, thereby upgrading the hydrocarbons within the...
