WELL-PRAETORIAN™ is a heavy duty wellbore filter and validation tool suitable for all downhole conditions and with robust, high performance features and is available in both heavy duty brush and normal duty wiper variants.
The WELL-PRAETORIAN™ is typically run as part of a comprehensive wellbore clean-up BHA, spaced out above the scraper and brush tools. While running in the hole, it wipes or brushes the casing while allowing fluid to bypass through the tool. When pulling out of hole the wellbore fluid is diverted through the heavy duty filter screen capturing all types of well debris in the debris chamber. This validates the effectiveness of the clean-up when the tool is emptied at surface.
The tool can be dressed with a standard duty rubber wiper cup, or a heavy duty brush element to suit heavy workover or high temperature applications.
