Title: David Brands: Innovator in Downhole Technology
Introduction
David Brands is a notable inventor based in Aberdeen, GB. He has made significant contributions to the field of downhole technology, holding 2 patents that showcase his innovative approach to solving complex problems in subterranean operations.
Latest Patents
One of his latest patents is titled "Alignment of Downhole Strings." This invention involves a downhole system that includes a downhole string insertable within a subterranean wellbore, along with a roller assembly coupled with the string. The roller assembly features rollers mounted on the lateral sides of the downhole string, which help reduce the resistance encountered when deploying the string within the wellbore. The string is designed to rotate about its axis with respect to the roller assembly, incorporating bearing surfaces to minimize rotational friction and ensure precise positioning to a designated orientation.
Another significant patent is the "Hydraulic Sand Removal Tool." This apparatus and method are specifically designed for removing sand and other debris from a wellbore, particularly suited for wireline operations with minimal surface equipment. The housing of the tool is lowered into the wellbore until it is close to the sand, at which point a valve is opened to allow the sand to enter a housing chamber. The housing can then be raised to the surface for sand removal. This invention features two chambers, each with a floating piston, and utilizes differential pressures to facilitate the sand removal process efficiently.
