Title: The Innovative Contributions of Dustin L Free
Introduction
Dustin L Free is a notable inventor based in Tulsa, OK (US), recognized for his significant contributions to the field of hydrocarbon extraction. With a total of 6 patents to his name, he has developed innovative methods that enhance the efficiency and sustainability of oil and gas production.
Latest Patents
One of his latest patents is focused on the "Reduction of water production from hydrocarbon containing subsurface." This invention aims to minimize the production of water from subsurface hydrocarbon-bearing intervals by treating the formation with an aqueous solution or sol of high molecular weight, water-soluble polyacrylamide (PAM). The polymer is absorbed in the formation and crosslinked in situ, which is achieved by flushing the formation with a crosslinking solution.
Another significant patent is the "Method of well completion with casing gel." This method allows for the recovery of much of the well casing if the well is later abandoned. It involves completing the well by utilizing various manipulative steps, leaving the lower portion of the annulus filled with conventional cementitious material and the upper portion filled with an aqueous gel. This gel comprises effective quantities of water, a water-soluble alkali metal silicate, and a water-soluble metal compound that releases multivalent metal cations to react with the silicate. This innovative approach enables the recovery of an economically significant portion of the casing if necessary.
Career Highlights
