  • Patent number: 10280705
    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target zone; thereafter, the remaining balloon sections are deflated or ruptured to permit the apparatus to be withdrawn through the production tubing.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: 10273762
    Abstract: An on-off tool for latching a sucker rod to a plunger rod has a housing, a pawl, guide pines, and a key. One end of the housing is connected to the sucker rod, and an interior of the housing defines a key slot terminating at a seat inside the interior. The pawl is disposed in the interior of the housing and is biased longitudinally preferably by disc springs. Bearings in the form of elongate pins are engaged between the pawl and the housing and dispose longitudinally in slots to guiding longitudinal movement of the pawl in the interior and preventing rotation of the pawl. The key has a head at its distal end that is passable through the key slot, interlockable with the pawl, and seatable on the seat. The key's head preferably defines a waist thereabout to provide the head with greater load bearing surface to engage the housing's seat.

  • Patent number: 10246966
    Abstract: An isolation device with seal element having substantial elongation properties at a time of setting and insubstantial elongation properties at time of drill out. That is, the seal element may be constructed of materials that are geared toward providing effective temporary sealing, for example to support stimulation operations. The seal is also tailored to change elongation properties over time such that upon sufficient exposure to downhole conditions the elongation properties may be substantially reduced. Thus, drillable removal of the device and seal element may be readily attained without undue concern over stretchable tearing of the element leading to an accumulation of large debris left behind in the well.

  • Patent number: 10221675
    Abstract: A non-straight sensor array within a gravity field, within a surface and cyclically surrounding a medial axis. The sensor array includes rigid bodies holding gravimetric tilt sensors, the rigid bodies being connected by flexible joints. The flexibility of the joints is constrained to two degrees of freedom. The shape of the path, the surface, and the medial axis are measured in at least two dimensions, using the tilt sensor data and the geometrical constraints of the joints. The cyclical geometry permits simultaneous measurement of lateral and axial deformations in deployments varying from axially vertical to axially horizontal, as well as improved fit of the array to surrounding surfaces. The field of use includes geotechnical measurements of soil and civil structures.
