Latest Patents

One of Cawthon's key achievements is his patent for "Hydraulic control of downhole tools." This patent describes a well tool apparatus that features a control arrangement capable of managing the response of a downhole tool by varying the bore-annulus pressure difference. The inventive mechanism includes a valve piston that is longitudinally slidable within a tubular controller housing, co-axial with the wellbore. This design allows for the opening or closing of a valve port to control fluid flow between the interior of the drill string and the tool. Additionally, a latch mechanism maintains the valve piston in place, ensuring it remains in an open or closed state until a specific axial movement occurs to unlatch it. The patent enhances operational reliability by employing a stay member that is automatically displaceable under hydraulic actuation when bore-annulus pressure exceeds a predetermined threshold.
