  • Patent number: 9765591
    Abstract: A process for plugging a wellbore, e.g., an oil or gas well, which comprises installing swelling elastomer sealing units across an interval of casing which is properly in the annulus space between the outside of the casing and the rock face. The swellable elastomer sealing units can also be used to seal off perforated casing, production screen and open hole completions. The plug and abandonment system is comprised of swelling elastomer units that are connected together to achieve a desired sealing contact length. These connected units may be hung off below or placed above a packer, cement retainer, cast iron bridge plug or setting slips. Both the tubular form of the plugging unit and the rod form of the plugging unit can be used in conjunction with conventional settable medium (cementing, barite or sized aggregate) plug setting operations. The elastomers incorporated are designed to swell with the current wellbore fluid and/or any possible future wellbore fluid.

    Abstract: A well tool for sealing against a wall of well includes an elongate mandrel. A seal assembly encircles the mandrel and can change between an unset state and an axially compressed set state. The seal assembly includes an annular elastomer seal element configured to radially deform into contact with the wall of the well in the set state. An annular anti-extrusion ring is included to compress the seal element and form a containing space with a garter spring embedded in the seal element. The garter spring is embedded in the seal element adjacent the axial end of the seal element and configured to span the gap between the anti-extrusion ring and the wall of the well in the set state. The containing space can prevent the seal element from excessive deformation.

  • Publication number: 20150114621
    Abstract: A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects.

An indexing feature is located between the sleeve and the mandrel passage wall and on a predetermined number of cycles disables the Belleville washer stacks from biasing the sleeve in an opposed direction as when pressure is applied. At this time the pressure in the mandrel acting on the differential piston area simply shifts the sleeve to open a lateral port so that fracturing through the cement that was earlier placed with the port closed can take place.

  • Publication number: 20120175135
    Abstract: A packer deployed well wall monitoring or transceiver assembly. The assembly may be particularly suited for use with swellable packers wherein the sensor or transceiver is delivered in a manner that substantially avoids damage thereto. Furthermore, the pre-deployment configuration of the assembly may enhance the deployment and reliability of the sensor in terms of formation monitoring over time. The deployment of the packer provides the energy required for the sensor or transceiver to contact the well wall. The packer elastomeric material provides or can be enhanced to provide isolation of the sensor or transceivers from extraneous borehole disturbances improving their signal to noise characteristics.

  • Patent number: 7878239
    Abstract: A fluid collecting apparatus inserted in a borehole for collecting fluid in the borehole. The fluid collecting apparatus may include a first packer and a second packer which are selectively adhered to an inside of the borehole, a first supply pipe and a second supply pipe which supply expansion fluid to each of the first packer and the second packer, and a guide tube which guides fluid in a collecting space between the first packer and the second packer to an outside of the borehole. Also, the second supply pipe moves with the second packer in a longitudinal direction of the borehole, and a passage which does not communicate with the first supply pipe is formed. Accordingly, the fluid collecting apparatus may independently control the first and second packers, and thus fluid in a desired depth and region within the borehole may be easily collected.
