Title: George B Holman: Innovator in Wellbore Technology
Introduction
George B Holman, a distinguished inventor based in Tulsa, OK, has made significant contributions to the field of wellbore technology, holding a total of seven patents. His innovative spirit and engineering expertise have enabled advancements in methods for completing wellbores, enhancing both efficiency and safety in the oil and gas industry.
Latest Patents
Among his latest patents, Holman has developed a method involving a low-density spacer fluid. This method introduces a low-density spacer fluid into a wellbore, followed by a completion fluid such as a cement slurry to effectively displace the spacer fluid. The innovative spacer fluid comprises a nonagglomerating carrier fluid, like water, and discrete dispersible density-reducing bodies, such as hollow spheres. These density-reducing bodies serve to minimize the hydrostatic head of the various fluids involved, ensuring that they do not exceed the fracture gradient in easily fractured formations.
Another notable invention by Holman is a diverter tool designed for setting a cement plug in a well. This tool features a hollow cylindrical body equipped with multiple cylindrical ports, which are arranged such that their axes are perpendicular to the main axis of the tool. This design enables efficient and effective management of cement placement in wellbore applications.
