Title: The Innovative Contributions of Barry Kent Holder
Introduction
Barry Kent Holder is a notable inventor based in Montgomery, Texas, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in geologic formation stimulation and hydraulic systems, showcasing his expertise in the oil and gas industry.
Latest Patents
One of Holder's latest patents is a device and method to stimulate a geologic formation with electrically controllable liquid propellant-waterless fracturing. This innovative application describes a device designed to stimulate a geologic formation using an electrically throttled liquid propellant. The device can be utilized for primary stimulation, altering the direction of a fracture in a wellbore during hydraulic fracturing, re-fracturing an existing interval to access new areas, or resetting fracture conductivity after an extended shut-in of the well. The device is deployed on tubing or wireline and is positioned close to the selected wellbore interval, where the liquid propellant can be selectively ignited. Its controls release and ignite an energetic material that produces expanding gas to increase pressure and stimulate the selected interval. The device comprises a reservoir for holding energetic material, a metering system to release propellant at a desired rate, an electrical ignition source to control output, a no backflow valve, and a control module that operates the metering and electrical ignition.
Another significant patent is the deep set safety valve, which features an actuator sub for generating hydraulic pressure. This sub housing includes an outer surface, a main flow passage extending through the sub housing, and a wall space formed between the main flow passage and the housing outer surface. A first hydraulic tube is positioned in the wall space, and an equalization port transmits pressure in the main flow passage to the first hydraulic tube. A drive motor drives a bi-directional hydraulic motor positioned in the first hydraulic tube, allowing for fluid output to a fluid outlet. The hydraulic motor is designed to permit reverse fluid flow when not under power, enhancing the efficiency of the system.
