    摘要: Methods of operating a downhole tool comprise thermally-controlling the tool by sensing a temperature and controlling the tool in response to the sensed temperature. Thermally-controlled downhole tools comprise a control element responsive to a change in temperature that control flow into, out of, or through a wellbore. Methods and systems for servicing a wellbore comprise using a thermally-controlled tool comprising a thermally-controlled valve (TCV) in a wellbore. The TCV includes a valve body comprising an injection port for allowing material to flow into or out of the wellbore and an opening/closing mechanism for regulating flow of the material through the injection port in response to a change in temperature. The valve body may be coupled to a downhole conduit. A plurality of TCV's may be arranged in the wellbore to control the injection of steam into the wellbore or the recovery of oil from the wellbore.

    摘要: A lateral wellbore junction is formed by methods and apparatus described herein. In one described embodiment, an apparatus includes a section of casing and a sleeve axially reciprocably disposed relative to an opening formed through a sidewall of the casing. In one described method, the casing section is positioned within a parent wellbore, the sleeve is shifted to provide access through the opening, and a lateral wellbore is drilled by passing cutting tools through the opening.

    摘要: A system and method for cutting windows for lateral wellbore drilling. A method of cutting a window through a sidewall structure for drilling a lateral wellbore through the window includes the steps of: providing an internal profile in the sidewall structure; then installing the sidewall structure in a parent wellbore; and then cutting the window through the sidewall structure, the cutting step including engaging a cutting tool with the internal profile. The cutting step may include resisting lateral displacement of the cutting tool due to engagement between the cutting tool and the internal profile.

    摘要: A casing exit joint with an easily milled and low density barrier. A casing exit joint for use in drilling a lateral wellbore outwardly from a parent wellbore includes a generally tubular window structure having a window formed through a sidewall of the structure. An outer sleeve is disposed external to the window structure, so that the sleeve overlies the window. A hardenable substance supports the sleeve against deflection toward the window. A method of drilling a lateral wellbore extending outwardly from a parent wellbore includes the steps of: providing a casing exit joint including a hardenable substance positioned in a sidewall of the casing exit joint; then installing the casing exit joint in the parent wellbore; and then cutting through the hardenable substance in order to provide access for drilling the lateral wellbore.
