  • Patent number: 10982512
    Abstract: A wellbore perforating apparatus and method according to which a perforating gun and a sensor sub are run into a wellbore toward a downhole location at which the wellbore is to be perforated. Detonable components of the perforating gun are energized to perforate the wellbore at the downhole location. An acceleration of the perforating gun and a pressure and a temperature of the wellbore are detected using the sensor sub during a time interval encompassing the energization of the detonable components. The detected acceleration, pressure, and temperature are compared to benchmark energetic responses for both detonation and deflagration events. Based on this comparison, a decision can be made as to whether an incubation period is needed to allow a reaction of the detonable components to weaken before retrieving the perforating gun from the wellbore.

  • Patent number: 10612340
    Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.

  • Patent number: 10544663
    Abstract: A method for well completion employs a combined plugging and perforating operation for creating multiple spaced-apart clusters of perforations and optional stimulation treatments in stages. For each stage to be completed, a frac plug, carried, for example, along a wireline bottom hole assembly with perforating guns, is set in the wellbore distal (toward the toe end of the well) of the most proximal perforation cluster of the previous stage, thereby maintaining open hole conditions that provide adequate flow past the most distal perforation clusters in the current stage and minimizing proppant accumulation in the wellbore from stimulation operations. The method further allows subsequent pump down of tools and equipment even with the plug set in the wellbore.
