Latest Patents
Logan's latest patents include the "Integrally formed sidepocket mandrel" and the "Sidepocket mandrel and method of making." The integrally formed sidepocket mandrel patent describes a method of forming one end of a sidepocket mandrel into a tubular shape that can accommodate an orienting sleeve. This process involves moving the sleeve through the formed end, securing it to the mandrel, and reforming the end to reduce its internal diameter for creating a premium female thread. The method emphasizes the creation of a one-piece body with a main bore and an offset bore, ensuring that both ends are tubular while leaving a middle section unworked.
The sidepocket mandrel patent focuses on a design that positions the valve pocket inside the mandrel body, featuring a deflector guide connected to the pocket. This design includes a pair of rails that allow flow control devices to enter the pocket while preventing open bore tools from accessing the guide path. An innovative aspect of this design is the inclusion of deformable lips on the rails, which prevent wirelines of well tools from catching between the body and the rails.
