  • Patent number: 10087708
    Abstract: An inflating container filled with formation plugging fluid is deployed at the target zone by a rigless apparatus. The inflating container can be in valved fluid communication with an explosive filled container, the explosive being ignited using a firing mechanism that is attached to the explosive filled container. The explosion expands gases in the explosive filled container which pass into the inflation container and displace the formation plugging fluid into the balloon sections and through the weakened portions of the central balloon to penetrate the walls of the target zone. The expanded central balloon is melted by the heat of the chemical reaction and a portion adheres to the formation wall thereby sealing the undesirable target zone; thereafter, the remaining balloon sections are deflated or ruptured to permit the apparatus to be withdrawn through the production tubing.

  • Patent number: 9540900
    Abstract: A sealing element comprises two distinct materials of different melting points. An outer shell material has a higher melting point than an inner core material. The core material can be a relatively low melting point metal, plastic or polymer. The seal is positioned in the wellbore and, in response to heating to a selected temperature, such as a bottom hole static temperature, the core material melts or softens. Upon melting or softening of the inner material, the outer shell's elastic modulus decreases, allowing longitudinal compression and radial expansion of the sealing element. The inner material can also thermally expand and thereby assist or cause radial expansion of the outer shell. The sealing element can provide a metal-to-metal seal with a casing or tubing. The cross-sectional shape of the outer shell can take various shapes to promote controlled compression, expansion and sealing.

  • Patent number: 9010414
    Abstract: An annular seal for a setting tool in a packer tieback extension comprises a downhole oriented packer cup assembly. As the tool is run in the hole the packer cup flexes as the rising hydrostatic pressure equalizes across the cup into what started as a zone with atmospheric pressure inside the packer tieback extension. Once the pressure is equalized the self energizing feature of the packer cup maintains grit and debris in the mud from entering the tieback extension where the spring loaded dogs of the setting tool are held in a retracted position. If the seal fails to equalize and allows a large differential across the setting sleeve from the surrounding annulus, the rupture disc breaks inwardly into the tieback extension so that pressure is equalized. If the packer is never set after being lowered to depth and the pressure from the tieback extension is equalized into the annulus.

  • Publication number: 20150068753
    Abstract: Provided are an apparatus and method for solution mining using cycling process in which a solvent is injected into underground useful ores to dissolve the useful ores and then collected again to obtain the useful ores. The cycling solution mining method includes a boring process for excavating the underground up to an ore deposit, a fracturing process to generate cracks in the ore deposit, an injection process for inserting a mining apparatus including an insertion rod having a pipe shape up to a lower portion of the well to inject a solvent that dissolves the useful ores into the ore deposit through the insertion rod, wherein a rotation force is applied to the solvent discharged from the insertion rod to increase a diffusion force of the solvent, and a production process for collecting the solvent, in which the useful ores are dissolved, again.

  • Patent number: 8960312
    Abstract: A well system can include a generally tubular production string extending to a surface location. A production packer seals off an annulus external to the production string. A swellable packer is interconnected in the production string between the production packer and the surface location. A method of mitigating a leak in a generally tubular production string can include interconnecting a swellable packer in the production string, and the swellable packer swelling, and thereby increasingly restricting flow through an annulus surrounding the production string, in response to fluid leakage through a sidewall of the production string. Another method can include interconnecting a swellable packer in the production string, and the swellable packer swelling, and thereby increasingly restricting flow through an annulus surrounding the production string, in response to a flow of hydrocarbons into the annulus from an interior of the production string.

  • Patent number: 8960314
    Abstract: A sealing assembly including a seal element at least partially formed from a shape memory material. The shape memory material urges the seal element to revert to an original shape upon exposure to a transition stimulus. The seal element is operatively arranged for sealing against a downhole structure when in the original shape. An interlock mechanism is included for holding the seal element in a deformed position in which the seal element is not able to seal against the downhole structure even after exposure to the transition stimulus. A method of setting a downhole sealing assembly is also included.

  • Patent number: 8960315
    Abstract: A downhole apparatus and support assembly has a radially expanding portion comprising a swellable elastomeric material selected to increase in volume on exposure to at least one predetermined fluid, and the support assembly is operable to be deployed from a first retracted position to a second expanded condition. The support assembly comprises an inner surface arranged to face the radially expanding portion, and at least a portion of the inner surface is concave. The support assembly may be configured to direct a force from the swellable material to boost or energize a seal created between the radially expanding portion and a surrounding surface in use.

  • Publication number: 20150041123
    Abstract: Systems and methods for accessing and/or harvesting hydrocarbons from a wellbore. A method may include modeling a well to determine a length of a stimulation zone in the production interval, wherein the model is based, at least in part, on a reaction time for a stimulation process. Packers are placed in the well to fluidically isolate the stimulation zone from other zones in the well. The targeted zone is stimulated, such as by acid treatment. Hydrocarbons may be recovered from the stimulation zone.

  • Publication number: 20150034300
    Abstract: A method of constructing a packer assembly can include installing a body lock ring on a mandrel, and then outwardly surrounding the body lock ring with a structure displaceable relative to the mandrel by a setting mechanism. A packer assembly can include a setting mechanism which displaces a structure relative to a mandrel, and a mandrel lock device which permits one way displacement of the structure relative to the mandrel, the mandrel lock device including a body lock ring and a bias sleeve which urges the body lock ring into gripping engagement with the mandrel, the bias sleeve and the structure being separate elements of the packer assembly. The bias sleeve can be secured against rotation relative to the mandrel while the structure is rotatable relative to the mandrel.
