Method and apparatus for testing setting tools and other assemblies used to set downhole plugs and other objects in wellbores
11708757 · 2023-07-25 · ·

A wireline conveyed, gas driven setting tool configured to set downhole tools including, without limitation, frac plugs, bridge plugs, cement retainers and packers. The setting tool is functioned by selectively igniting a power charge inside of a firing head. As the power charge burns, it generates gas that acts upon a piston area to stroke the setting tool. A dampening media, as well an optimized flow area at or near the distal end of the setting tool, act to slow the setting stroke. A mobile testing assembly can confirm that a setting tool or other associated equipment was manufactured and assembled properly, and is fit for service, prior to running the setting tool a well bore. The mobile testing assembly and testing method can be employed in a shop or other manufacturing facility, or on a well site or other remote location.

Determining gas leak flow rate in a wellbore environment

An estimated gas leak flow rate can be determined using a teaching set of concentration profiles, a regression model implemented by a machine-learning subsystem, and a subset of attributes measured within an environment. The teaching set of concentration profiles can include gas flow rates associated with relevant attributes. The regression model can be transformed into a gas leak flow regression model via the machine-learning subsystem using the teaching set. The subset of attributes measured within the environment can be applied to the gas leak flow regression model to determine other attributes absent from the subset of attributes and an estimated gas flow rate for the environment. A gas leak attenuation action can be performed in response to the estimated gas flow rate.

Systems and methods for radar detection

Embodiments of the present invention use radar technology to detect features or conditions in a well. A radar unit having an electronics subsystem and an antenna subsystem is positioned downhole in the well. The radar unit is coupled receive power from and communicate with to a surface system. The electronics subsystem generates RF signals which are provided to the antenna subsystem, generating radar wavefronts that are propagated toward areas of interest (e.g., farther downhole). The radar wavefronts may be electronically or mechanically steered in the desired direction. The antenna subsystem receives radar signals that are reflected back to the unit by features or conditions in the well. The received reflected signals are converted to electronic signals that are interpreted by the electronics subsystem of the radar unit or by the surface system to identify the features or conditions that caused the reflections.
