  • Publication number: 20040188090
    Abstract: The present invention relates to a method to increase the bonding forces of a hydraulic cement to a subterranean pipe (such as a casing) by the addition of at least one cementitious expansive agent to increase the bulk volume of the cement plug and a latex. The method of the invention includes positioning a platform in a downhole pipe below the desired cement plug interval, positioning a plug dump bailer tool comprising a tubular storing chamber for a cement slurry and a valve to discharge the cement slurry on and above the platform and discharging a cement slurry that comprises an expansive agent and a latex in quantities enough to increase the shear-bond between the downhole pipe and the cement plug. The invention allows a significant reduction of the height of the cement plug and therefore of the number of dump-bailer operations required for placing a plug.

  • Patent number: 6439306
    Abstract: A tool string for use in wellbore includes a sampler device having a port to receive pressure in an annulus region of the wellbore. An elevated pressure is communicated to a rupture disk assembly located in the port to rupture the rupture disk assembly. The elevated pressure is then communicated through a passageway to an activating mechanism of a sampler device. The activating mechanism is adapted to open a flow control device that controls flow through one or more ports of the sampler device. In another arrangement, the activating mechanism of the sampler device may include a pressure transducer for receiving pressure pulse signals. In response to pressure pulse signals of predetermined amplitude and pulse width, the pressure transducer may generate an activating signal to an actuator to operate the flow control device. Yet another arrangement includes a timer for activating the sampler device. The timer is actuatable by an elevated pressure.

  • Patent number: 4696343
    Abstract: A dump bailer is lowered on a wireline in a well through tubing for placing a cement slurry on a retainer located in the well. The dump bailer has a weight bar assembly that includes upper and lower sections that are extensible relative to each other. The upper weight bar section has an electrical contact that engages the electrical contact mounted in the upper end of the housing of the dump bailer. The lower section has a seal which separates the housing into upper and lower chambers. Cement is pumped in from the bottom, pushing the weight bar assembly upward until the contact on the upper weight bar section engages the upper contact. A detonator is located on the bottom of the lower weight bar section. Explosive force of the detonator transmits a shock wave through the cement slurry to expel a shear plug located on the bottom of the housing. The weight bar assembly pushes the cement from the slurry once this occurs.

    Abstract: In the representative embodiments of the new and improved apparatus disclosed herein, a string of full-bore well tools are arranged to be suspended from a pipe string in a well bore penetrating an earth formation in flow communication with the well bore. A full-bore packer coupled to the pipe string is operated from the surface for isolating the well bore interval below the packer from the fluids in the well bore thereabove. To test the formation, a test valve coupled to the pipe string is selectively operated from the surface for opening the pipe string to the flow of formation fluids from the isolated well bore interval. Thereafter, when it is desired to obtain a sample of the formation fluids flowing in the pipe string, the new and improved full-bore sample-collecting apparatus coupled to the pipe string is selectively operated from the surface to admit the fluids in the pipe string into an annular sample chamber within the new and improved apparatus.

  • Patent number: 4374543
    Abstract: A method and apparatus are disclosed for sequentially treating two vertically separated zones in a well bore, utilizing a packer having a fluid passageway therethrough set between the zones, a pressure shearable plug at the lower end of the packer, and a retrievable fluid plug at the upper end of the packer. Once the packer, with the shear plug on its lower end, is set in the well bore between the two zones, the retrievable plug is placed in the upper end of the packer to isolate the shear plug from well pressure in the upper zone, and the desired treating steps are performed on the upper zone. The retrievable fluid plug is then removed and tubing run to the packer to establish communication with the shearable fluid plug. The shearable plug permits static pressure testing of the tubing string and seals before communication is established with the lower zone, and then may be removed by elevating fluid pressure to sufficiently shear the plug.
