Title: The Innovative Contributions of Robert L Coffee
Introduction
Robert L Coffee is a notable inventor based in Newkirk, Oklahoma, recognized for his significant contributions to the field of hydrocarbon production technology. With a total of 4 patents to his name, Coffee has developed innovative solutions that enhance the efficiency and effectiveness of wellbore operations.
Latest Patents
One of Coffee's latest inventions is the "Downhole activated process and apparatus for deep perforation of the formation." This invention pertains to a method and apparatus designed for perforating formations in wellbores established for hydrocarbon production. The process utilizes explosive materials carried in pistons, which are integrated within the pipe casing or collars. This design ensures that the pistons remain within the maximum outward profile of the pipe string, allowing for unobstructed movement and placement within the wellbore. The ability to rotate, reciprocate, and circulate the pipe string enhances the installation process, particularly in deviated or long-reach wellbores. Once positioned, the pistons can be deployed using various methods, enabling them to move outward with sufficient force to create a complete annulus for cementing. After cementing, the explosive charges in the pistons can be detonated to perforate the formation, facilitating hydrocarbon production.
Another significant patent is the "Pressure monitoring apparatus," which is designed for use in a tubing string with a landing nipple located above a monitored well zone. This apparatus includes a plug body, a mandrel sleeve, a pressure communication mandrel, and a pressure sensor. The design allows for effective monitoring of pressure fall-off in subsurface formations after fluid injection, as well as monitoring bottom hole shut-in pressure buildup in production wells.
