    Abstract: A bridge plug with a selectively blocked flow passage is delivered on wireline and pumped down to the desired location and set. A casing pressure test can be performed above the bridge plug while shielding the formation below from excess pressure from the pressure test. To the extent there are producing zones below the bridge plug or adjacent injection wells that could communicate with the borehole, the plug isolates those pressures from below. After the pressure test is completed, a rupture disc is blown in a passage through the bridge plug and flow is then used to deliver completion equipment to a horizontal portion of the borehole and preferably on wireline.

  • Patent number: 9409821
    Abstract: Particulate polymeric materials may be added to a cement slurry to adjust the linear thermal-expansion coefficient of the set cement. The coefficient of the set cement is optimized by considering the linear thermal-expansion coefficient of the casing, as well as the mechanical properties of the formation rock. When placed in a subterranean well having at least one casing string, cement sheaths with optimal linear thermal-expansion coefficients may be subjected to lower compressive and tensile stresses during downhole-temperature changes. Such cement slurries are particularly advantageous in the context of thermal-recovery wells.

  • Patent number: 9010435
    Abstract: The invention relates to oil-and-gas industry and can be used in emergency killing of wells. The method of emergency killing of a well of underwater head position comprises a cementing composition squeezing, wherein depth of the well section to be cemented is defined basing on the well condition and pressure in it, an injector, fixed on the tank with cementing composition and placed inside a bag made of some flexible material, is bottomed and inserted into the wellhead, the bag being filled with cementing composition which is squeezed into the bag through the injector from the tank, and providing for a firm contact of outer surface of the bag with inner surface of the well, the injector being kept at a target depth by means of the weight of the whole structure filled with the cementing composition, pressure in the bag being maintained till the cementing composition hardening.

  • Publication number: 20150075791
    Abstract: The present invention is a valve tool utilized for hydraulically fracturing multiple zones in an oil and gas well without perforating the cement casing. An oil/gas well completion method involves the use of a valve that is installed as part of the casing string of the well. A mandrel-less casing provides for cement flow within the casing when the valve element is in a closed position and allows for axial flow of fracturing fluid through the cement casing to fracture the formation near the valve when the sleeve is open. The invention disclosed herein is an improved valve used in this process.

  • Publication number: 20150060071
    Abstract: Present embodiments are directed to coupling a cementation assembly with a hung or set liner string in a well and moving the liner string during a cementation operation. Specifically, for example, a process in accordance with present techniques includes running a cementation assembly into a well on drill pipe and engaging, with a distal end of the cementation assembly, a liner top assembly of a liner string that is positioned downhole in the well, wherein the liner string was previously positioned downhole in the well without being cemented into the well. Further, the process includes latching the cementation assembly with the liner string such that movement of the cementation assembly is translated to the liner string, and flowing cement through the drill pipe and into the liner string while moving the cementation assembly and the liner string.

  • Publication number: 20150053405
    Abstract: A single trip method allows for perforation, cleaning the annular space around the perforations in an existing tubular and then delivering a sealing material through a combination tool that is used for cleaning and then sealing. For sealing the tool is positioned by the lowermost perforations with a bypass around spaced seals that straddle the outlet port for the sealant. There is an open bypass through the tool and around the spaced seals as the sealant is delivered so that the sealant goes above and below the spaced seals. The open bypass allows the tool to be repositioned as the sealant is delivered. The tool is removed with the string. A separate through passage is selectively opened for removing excess sealant in conjunction with the bypass passages. The sealant can be squeezed with a seal on the string to effectively close the bypass letting pressure through the through passage squeeze.
