  • Patent number: 11988056
    Abstract: A system and method for injecting bailer content utilizing a dump bailer having an elongated, flexible bailer receptacle secured between a head assembly and an injection assembly. Disposed within the dump bailer are first and second piston assemblies, each of which includes a piston having a central fluid passage with a pressure actuated flow control mechanism in the form of a rupture disk disposed along the fluid passage of the piston. An electric, positive displacement pump within the head assembly draws wellbore fluid into the dump bailer assembly to drive the first piston assembly towards the second piston assembly so as to release bailer content into a wellbore. The elongated flexible bailer receptacle may be a hose stored on a bailer receptacle reel, which hose may be paid out by the reel to a length that corresponds with a volume of bailer content to be released into the wellbore.

  • Patent number: 11939833
    Abstract: A wiper plug can be used in wellbore operations. The wiper plug can include a fishing neck located at a rear portion of the plug. The fishing neck can be a male or female fishing neck. A corresponding male or female fishing tool can be used to retrieve the wiper plug from a tubing string. The wiper plug can include a nose that can land on a landing tool or a female fishing neck of another wiper plug. The wiper plug can be introduced into the tubing string before or after a cement composition. The wiper plug can include a rupture disk that allows an operator at a wellhead to observe a pressure change to indicate the location of the wiper plug and fluid within the tubing string.

  • Patent number: 11215029
    Abstract: A downhole tool component may be deployed in a wellbore such that a flexible portion of the tool component is constrained to a first range of motion. By applying a force to the flexible portion, a flexible carrier material applied around the flexible portion of the tool component may be compressed and collapsible objects carried by the carrier material to be collapsed to permit the flexible portion to move through a second range of motion greater than the first range of motion. Cement in the wellbore may constrain movement of the flexible portion, and an elastomeric sheet may be compressed, and glass spheres carried by the elastomeric sheet may be crushed to create voids through which the flexible portion may move. Closure of a barrier valve may be effected by the operation of an actuator assembly that relies on movement of the flexible portion through the second range of motion.
