Title: John Howard Striegler: Innovator in Directional Drilling
Introduction
John Howard Striegler is a notable inventor based in Richardson, TX (US), recognized for his contributions to the field of directional drilling. With a total of 8 patents to his name, Striegler has made significant advancements that enhance drilling efficiency and accuracy.
Latest Patents
Striegler's latest patents include a "Medium Curvature Directional Drilling Method." This innovative method involves drilling medium curvature deviated wellbores with a radius of curvature ranging from 200 feet to 400 feet. The technique utilizes downhole drilling assemblies designed for both the curved and horizontal portions of the wellbore. These assemblies are connected to a drillstem composed of elongated elastically bendable members, which are cyclically compressively stressed during rotation. The design minimizes the risk of buckling during drilling, ensuring a more efficient process.
Another significant patent is the "Method for Drilling Drainholes Within Producing Zone." This method allows for the drilling of drainholes through subsurface formations without intersecting upper or lower boundaries. It employs a directionally sensitive measurement while drilling device to assess formation properties, enabling the drill to change direction when proximity to a boundary is detected.
