Latest Patents

One of David's latest patents is titled "Methods for sealing leaks in oil and gas wells." This method involves removing a portion of an inner casing string within a wellbore to access an annulus associated with an area of fluid leakage. The process includes filling a first portion of the annulus with a first metal alloy to form a first metal alloy layer, followed by filling a second portion with cement to create a cement layer over the first metal alloy layer. Finally, a third portion is filled with a second metal alloy to form a second metal alloy layer over the cement layer. Together, these layers effectively seal the annulus.

Another significant patent is "Drill element and associated equipment and methods." This invention pertains to a drill string element used in borehole drilling. The drill string element comprises a main body and a flow control mechanism. It defines a first aperture, another aperture, and a passage that provides a fluid flow path between the two apertures. The flow control mechanism is designed to inhibit fluid flow in a first operating mode while allowing it in a second operating mode.
