Title: Innovations of John G. Eller

Introduction

John G. Eller is a notable inventor based in Anchorage, AK, who has made significant contributions to the field of oil and gas production. With a total of six patents to his name, he has developed innovative methods and tools that enhance drilling operations.

Latest Patents

One of his latest patents is a method and apparatus for milling a window in casing. This process is designed to create a small window or notch in the casing of an oil or gas producing well, allowing for the drilling of a lateral well branching off from the main well. The method utilizes a wireline milling tool to perform a low-cost operation, which can then be followed by a more expensive heavy-duty coil tubing milling operation to create a full window, measuring 4-6 feet in length. This innovation addresses previous challenges faced during milling operations, such as the absence of circulating drilling fluid to remove metal swarf and the need for tool support by casing during the milling process.

Another significant patent by Eller is the gravity-driven reverse circulator tool. This tool features nested pipes that close a hole in one of the pipes when fully nested. When the drill string is lifted, the pipes partially separate under gravity, exposing the hole. This design allows for both lifting and rotation to open the tool, providing a more efficient method for drilling operations.
