  • Patent number: 7195033
    Abstract: Apparatuses and methods for accurately determining the position of a sliding or rotational sleeve valve in real time are disclosed. The apparatus comprises fiber optic cable based sensors which are either linearly or circumferentially arrayed in the housing that surrounds the sleeve and which can comprise bare cable or cable having fiber Bragg gratings (FBGs). As the sleeve slides or rotates within the housing, the sensors in the arrays are deformed, and this deformation can be correlated to sleeve position by assessing the sensor's reflectivity profiles. Deformation of the sensors is achieved by various mechanical and/or magnetic schemes incorporated into the sleeve.

  • Patent number: 7108060
    Abstract: Method and apparatus for fracturing different levels of a completion interval in a well. A workstring lowers a fracturing string which, in turn, is comprised of a base pipe which is blank except for perforated sections spaced along its length. Screen may be provided over said sections to block the flow of sand into the base pipe. An alternate flow path (e.g. shunt tubes) extends along the base pipe and has one or more outlets spaced along its length. A slurry is flowed into the annulus surrounding the fracturing string. As liquid is lost from the slurry, sand from the slurry will form bridges at said perforated sections thereby isolating portions of the annulus. Slurry then flows through the shunts tube(s) and out into the isolated portions to fracture the different levels in the completion interval.

  • Patent number: 6983796
    Abstract: A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion.

  • Patent number: 6830104
    Abstract: Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand control screen (e.g., screens, screened pipes, perforated liners, prepacked screens, etc.) and an outer shroud assembly mounted over the sand screen in the wellbore adjacent the zone to be completed, the shroud having perforated and blank (non-perforated) segments with the blank segments corresponding to selected intervals of the wellbore, for example problem zones such as shale streaks or isolated zones where flows are restricted by mechanical seals or packers, and injecting particulate material into the wellbore, whereby gravel packing takes place in the remaining length of the wellbore/shroud annulus without voids. The inner annulus between the shroud and screen provides an alternate flow path for the slurry to bypass the blocked intervals and continue with its placement.

  • Patent number: 6588508
    Abstract: A tool string for use in a well includes a filter sub (or trapped pressure regulator sub) that is used with other components to reduce trapped pressure. The filter sub filters out debris that may occur from various types of downhole operations, such as perforating operations. By filtering out larger debris, only gases, liquids, and smaller particles are allowed to enter various components of the tool string. Without the presence of larger solid debris inside certain components of the tool string, the likelihood of plugs being formed is reduced so that gases and liquids can more readily pass out of the tool string as the tool string is retrieved to the surface of the well and the well hydrostatic pressure decreases.
