Title: Innovations by Christopher P. Mullin in Downhole Technology

Introduction

Christopher P. Mullin is an accomplished inventor based in Houston, TX (US). He has made significant contributions to the field of drilling technology, holding 2 patents that enhance the efficiency and safety of downhole operations.

Latest Patents

One of his latest patents is focused on downhole motor stall detection. This innovative drilling system includes a drill string, a plurality of sensors, and a computing system. The drill string features a downhole motor, with sensors coupled to it. The computing system processes measurements from the sensors to compute a motor stall index. By comparing this index to a motor stall threshold, the system determines whether the downhole motor has stalled. If a stall is detected, the system adjusts the operation of the drill string to restart the motor.

Another notable patent involves process automation that optimizes the placement of a drill bit at the bottom of a wellbore. This system utilizes an automated control system and downhole tools. It determines when a drill bit has reached a predetermined distance from the bottom of the wellbore. Upon reaching this depth, the system transmits a rate of penetration set point to reduce the lowering speed of the drill bit. It also monitors the rate of penetration to ensure stability and automatically tars the surface weight on the drill bit and differential pressure.
