Latest Patents

One of Neil's latest patents is the "Dual action jet bushing." This invention utilizes an eductor sub as part of a downhole debris removal apparatus. It features an eductor outlet port that can be selectively closed during the run-in phase, allowing the flow pumped through a tubing string to reach the lower end of the debris removal tool. This design fluidizes the debris and helps prevent the tool from becoming stuck as it descends to the desired depth. Upon reaching the target depth, a ball lands on a seat connected to a sleeve, which is displaced to open the eductor outlet. This allows future flow down the casing string to create reduced pressure within the tool, drawing some of the exiting flow in a downhole direction to facilitate debris removal.

Another significant patent is the "Completion method for well cleanup and zone isolation." This method isolates a lower zone while high-rate circulation occurs above to clean debris from the wellbore. During circulation, pressure fluctuation-sensitive equipment in a lower completion is isolated with a tubing valve. This prevents debris from clogging the inlet pressure passages to equipment below the isolation valve. After circulation, the packer is unset, and the tubing valve is opened. A wellbore filter tool then directs well fluids through a screen, capturing debris as the string is pulled toward the surface.
