Title: Innovations by Mark D Mueller

Introduction

Mark D Mueller is a prominent inventor based in Santa Maria, California. He has made significant contributions to the field of drilling technology, holding a total of 12 patents. His innovative methods and tools have transformed the way difficult boreholes are drilled and completed, minimizing risks and costs.

Latest Patents

One of his latest patents is the "Drag analysis method," which is an iterative planning and monitoring method for drilling and completing challenging boreholes. This method avoids unnecessary risk or cost by providing multiple point value probability estimates of drilling problems based on various drilling variables. The approach allows for the perturbation of expected drilling variables within physically feasible bounds, leading to multiple estimates of corresponding indicator values. The probability of each estimate is calculated to assess the likelihood of unwanted conditions, enabling the implementation of mitigation measures when necessary. This innovative method helps in quickly identifying critical variables, thus avoiding unnecessary mitigation procedures and unwanted drilling risks.

Another notable invention is the "Downhole tube turning tool." This tool allows for the drilling and completion of laterals without the need for articulated bending tools, underreaming, high fluid pressure, or separate running of completion tools. The turning tool utilizes a rigid bent pipe section that can be run downhole within standard diameter well tubulars. It bends coil tubing at an ultra-short radius of curvature while being run into the wellbore, enabling effective jet drilling of laterals. After drilling, the lateral can be completed using the coil tubing, such as gravel packing by pumping a slurry through the tubing while withdrawing it from the lateral.
