Title: Innovations by Gary D Herring in Well Treatment Methods
Introduction
Gary D Herring is an accomplished inventor based in Anchorage, AK. He holds 2 patents that focus on innovative methods for well treatment. His work has significantly contributed to the efficiency and effectiveness of sealing formations in well casings.
Latest Patents
One of Herring's latest patents is a well treatment method using sodium silicate to seal formations. This method involves a squeeze silicate operation carried out through coiled tubing to seal upper perforations in a well casing, preventing the flow of excess gas. The sodium silicate mixture used contains a diverter material that rapidly builds a filter cake on the formation as it is squeezed through the perforations. This filter cake forms a barrier that effectively limits the depth of penetration of the silicate while providing a good seal against flow through the squeezed perforations.
Another significant patent by Herring is a squeeze cement method using coiled tubing. This method allows for the well tubing to remain in place, eliminating the need for a workover rig. It requires a smaller volume of squeeze cement and allows for precise control of the pressures involved in the squeeze operation, minimizing the risk of fracturing the formation. The process involves isolating the wellbore adjacent to the perforations and flowing a packing fluid with a density greater than the cement through the coiled tubing. After placing the cement, a contaminating liquid is flowed down the coiled tubing to mix with the cement left in the casing, preventing it from setting.
