Title: Innovations by Inventor Bob L Sullaway
Introduction
Bob L Sullaway, an inventive mind hailing from Duncan, Oklahoma, has made significant contributions to the field of engineering, particularly in well completion technologies. With 13 patents to his name, Sullaway showcases a commitment to innovation that enhances operational efficiency in the oil and gas industry.
Latest Patents
Among his latest inventions is a sophisticated casing valve. This casing valve features an outer housing equipped with a sliding sleeve, complemented by first and second seals that define a sealed annulus within the housing. A latch mechanism within this annulus secures the sliding sleeve in its designated positions. The design includes multiple housing ports and sleeve ports that are initially obstructed by disintegratable plugs. A third seal between the sleeve and housing isolates the ports, allowing for precise control when the sleeve is either in its first or second position. The innovative lug and groove alignment mechanism within the sealed annulus facilitates seamless transition between these positions.
Additionally, Sullaway's work on well completions using casing valves is noteworthy. This process involves cementing a casing string in place, followed by utilizing a jetting tool assembly to interact with a sliding sleeve of a casing valve. This assembly elegantly transitions the sleeve to an open position, allowing hydraulic jets to remove disintegratable plugs. This operation establishes communication between the subsurface formation and the interior of the casing string, significantly enhancing well productivity.
