Downhole Filter Subs
KINGWELL offer Filter Subs in all sizes and connections as well as in Non-Magnetic and Steel, giving you the ability to place in multiple locations in the BHA or above. While designing our filter subs we conducted expert engineering and metallurgy studies and kept in mind the total flow area around and through the filter, which allows our customer to pump at maximum flow rates without the worry of erosion. Due to the engineering of the filter's creatively designed port holes, we have also significantly reduced the possibility of total plug up.
Our goal is to provide a means of protection for the equipment most susceptible to jamming (plugging up) in your Bottom Hole Assembly.
All of our Filter Subs are API Spec 7-1.
4 3/4” w/ NC38
6 1/2’’ w/ NC46

Drill Pipe Screens
High Flow / Slow Flow..
We stock screens from 2-4 feet in length and thickness ranging from 7-16 gauge.
Oil well drilling equipment must meet the demands of the project. Mason Specialty Tools realizes that different situations call for different screens so we have screens for both high flow and slow flow applications in the oil well drilling process. If we don't carry a screen that fits the conditions in which you are drilling, we have the resources to quickly design and produce a screen that will.
Downhole filters are protective mechanisms that are installed above drill motors that would typically wear out when constantly exposed to solid surfaces.
These filters will prevent nozzles and motors from clogging up with debris thus saving you time on projects. After retrieval at the surface, these filters can be disassembled and cleaned and re-used.
