Latest Patents

Cottrell holds a patent for a Differential Safety Valve. This valve is designed to limit the differential pressure applied to a downhole tool. It features a housing and a movable piston/mandrel assembly. In its closed position, drilling mud or other fluid can be communicated through a central bore of the valve to the tool. When the differential pressure exceeds a predetermined value, the piston/mandrel assembly shifts to allow fluid to bypass the tool, thereby relieving the pressure. This mechanism provides enhanced control over the pressure values, making it a valuable innovation in the field.
