Plugging device construction method using swellable-coated filaments
A recently granted patent (Publication Number: US11859317B2) discloses a method for constructing a plugging device designed for use in subterranean wells. The method involves incorporating multiple filaments into the plugging device and coating each individual filament with a swellable material before forming the body of the device. This innovative approach aims to enhance the effectiveness of the plugging device in well applications by utilizing a specialized construction process.
Furthermore, the patent claims detail additional steps in the method, such as incorporating the filaments into multiple strands of yarn, forming a twine with these strands, and coating the filaments post twine formation. The use of a water-swellable material in the coating process is highlighted, emphasizing the potential for improved performance in well environments where the material can swell. These claims underscore the technical intricacies involved in the construction of the plugging device, showcasing a novel method that could offer advantages in subterranean well operations.
