Operation
The Abrasive subs can be run as part of a tubing string or as part of a coiled tubing bottom hole assembly. The desired nozzle configuration is selected and fitted to the sub. Once at the required depth the fluid can be pumped through the carbide nozzles to produce multiple perforations. Alternatively when an abrasive jetting head is deployed below a motor fitted with the WellEnTech STS™ sealed bearing section, the BHA can be used to sever drill pipe or tubing. Single, dual or cemented casings can be cut in a single trip. The time taken to sever/perforate any given tubular depends on various factors such as the sub or head size, tubular size and weight. WellEnTech will provide an engineered solution as well as technical support to suit specific operational requirements.
