Latest Patents

One of Kannan's latest patents is an "Apparatus for carrying chemical tracers on downhole tubulars, wellscreens, and the like." This invention features an access device that installs on a wellscreen joint during manufacture, allowing for the installation of tracer elements adjacent to the joint's screen jacket. The design includes a removable portion of the access device, enabling the installation of tracer elements after the joint has been manufactured. Once the tracer elements are in place, the access device can be reassembled and locked securely. Various mechanisms can facilitate the partial removal of the access device, installation of the tracer elements, and reassembly. For instance, an end ring holding the jacket on the basepipe can have channels for tracer element insertion, with a removable cover providing access.

Another significant patent is the "Test packer and method for use." This downhole tool features a throughbore and is designed for use in a tubular located in a wellbore. It includes a sealing element that seals the annulus between the tool and the inner wall of the tubular. The design allows fluids in the annulus to flow past the sealing element when it is in a sealed position. Additionally, it incorporates at least one valve in fluid communication with the flow path, permitting fluid flow in one direction while preventing it in the opposite direction.
