Latest Patents

Umphries' latest patents include advancements in downhole charge carriers. One of his inventions discloses an improved downhole explosive charge carrier that utilizes a unique staggered charge pattern and a mounting configuration. This design allows for the use of a straight, axially-located detonator, achieving a greater number of shots per unit length compared to conventional carriers. Additionally, this invention reduces interference caused by the detonator and the proximity of shots, enhancing the performance of individual charges. This allows for smaller charges to achieve the same perforation size. Another patent reveals downhole explosive carriers with charges mounted in a staggered spiral pattern. This configuration increases the number of shots that can be fired per unit length while enhancing the spacing between explosive charges. This advantage minimizes potential interference between fired shots and pressure changes, resulting in a greater perforated hole size.
