  • Patent number: 7874366
    Abstract: To perform a cleanout operation in a wellbore, a cleaning tool having a coiled tubing and an electrical pump assembly is run into the wellbore. The electrical pump assembly that is located in the wellbore is activated. In response to fluid flow generated by the electrical pump assembly, removal of debris from the wellbore is caused by directing fluid containing the debris into the coiled tubing for delivery to an earth surface.

  • Patent number: 6439313
    Abstract: A method of machining a workpiece in a subterranean wellbore comprises the steps of: (a) providing a workpiece that comprises (1) a first section that comprises a first material, and (2) a second section that comprises a second material, the second section forming at least one surface of the workpiece; (b) placing the workpiece in a subterranean wellbore that is surrounded by a geologic formation; and (c) machining the workpiece to remove at least part of the second material in the second section, whereby at least one surface of the workpiece is formed into a desired configuration. This method allows, for example, a landing nipple to be installed in a wellbore, and customized locking recesses to be formed in the inner surface of the nipple at a later time.
