  • Patent number: 10138706
    Abstract: A technique includes running a seat assembly on a conveyance line into a tubing string, which has previously been installed in a well. The seat assembly includes a seat, which is adapted to receive an untethered object. The technique includes attaching the seat assembly to the string at a location downhole in the well; receiving the object to create a fluid barrier; and diverting fluid using the fluid barrier.

  • Patent number: 8944171
    Abstract: A technique includes deploying a string that includes a seat assembly in a well; and running a shifting tool in a passageway of the string. The shifting tool shifts the seat assembly to cause the seat assembly to transition between a first state in which the seat assembly forms a seat that is adapted to allow an untethered object communicated in the passageway of the string to pass through the seat assembly to a second state in which the seat assembly is adapted to catch the object to form a fluid barrier in the string. The fluid barrier is used to divert fluid in the tubing string to perform, for example, a stimulation operation.

  • Publication number: 20130340599
    Abstract: A perforating gun of unique port and port plug architecture. The gun may include ports with separate guide channel and engagement regions for receiving a port plug. Once more, the engagement region may be offset from the central axis of the guide channel and overall port. Thus, the engagement region of the port as well as the matching engaging mechanism of the port plug may be out of the direct line of fire when a perforating application takes place. The same may be true of a seal for the port plug. Therefore, achieving adequate engagement and sealing of the port with such plugs may be more effective, for example, in spite of the guide channel and other portions of the gun carrier beginning to exhibit post-perforation bulging.

  • Patent number: 8439114
    Abstract: The present invention provides an apparatus and method of orienting perforating gun strings conveyed on a tool string. One embodiment of the present invention provides an orienting weight provided in a portion of the perforating device, such as the shaped charge, the loading tube or the gun housing. An adapter is provided intermediate the tool string that facilitates conveyance of the gun string downhole. Additionally, the adapter enables the gun string to rotate independent of the tool string.
