Title: Innovations by David W. King: A Pioneer in Wireline Technology

Introduction

David W. King, a notable inventor based in Fort Worth, Texas, has made significant contributions to the field of wireline technology. With a total of five patents to his name, King has focused primarily on developing tools and methods used in the oil and gas industry, specifically for downhole operations.

Latest Patents

Among King’s latest inventions is the "Wireline Shifting Tool Apparatus and Methods." This innovative tool improves existing wireline borehole operations by incorporating upwardly extending upper dog means and downwardly extending lower dog means. The upper dog means can be extended and retracted based on the tension in the wireline, while the lower dog means is designed to be longitudinally movable relative to the upper dog means. This tool allows operators to efficiently conduct shifting operations on various devices within wellbore conduits, along with methods to utilize it for initiating shifting movements effectively.

Another significant patent by King is the "Wireline Latching Apparatus and Method of Use." This apparatus is particularly important for wireline instruments that measure temperature and pressure in flowing oil and gas wells. It features a tubular body connected to the instrument, with three pivotally mounted arms designed to engage a downwardly facing shoulder located in the well pipe. This design ensures that the arms bear against the shoulder while wireline tension prevents whipping, thus enhancing safety and accuracy during measurements.
