Title: Innovations of Johnny E Jurena
Introduction
Johnny E Jurena is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of subsea technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and safety of operations in wellheads.
Latest Patents
Jurena's latest patents include a "Location-and-rotation feedback tool for subsea wellheads and method of operating same." This innovative tool provides accurate feedback on the location and orientation of well components during running operations. The device is designed to be secured on a tool stem above a running tool and features a body, a circumferentially extending groove, and a hole that vents to the bore of a blowout preventer. The circumferential groove aligns with a fluid line port in the blowout preventer, allowing for location feedback via fluid line pressure. Additionally, the hole provides rotation feedback through the same mechanism.
Another significant patent is the "Device to insert a flexible member into pressurized wellhead housing." This invention includes a drive assembly that intermittently reciprocates a hose feed into the wellhead housing. This design allows the hose to navigate past obstacles within the housing, such as within annuluses between tubulars. The drive assembly utilizes rollers that frictionally contact the hose, which are rotated by a hand crank, creating an orbital/reciprocating motion.
