Introduction

Mark Edward Keller is an inventor associated with Houston, Texas, and Halliburton Energy Services, Inc. His patent work addresses a system designed to combine several well-construction and completion operations in a single trip.

Latest Patents

Keller is credited with 1 patent: “Single-assembly system and method for one-trip drilling, casing, cementing and perforating.” The invention describes a casing string with a latch assembly and a drillstring latched inside it. The drillstring can carry tools for perforation and stimulation, with optional pressure-while-drilling equipment and packers.

In the described process, the casing is cemented in place through a cement valve. The drillstring is then unlatched and raised to the desired completion position before perforation and stimulation. These operations can be repeated for multiple completions. The drillstring may be removed or left seated to help control production, while logging instruments can support steering and completion decisions.

Career Highlights

Keller’s listed patent reflects work on integrating drilling, casing, cementing, perforating, and stimulation operations. The approach is intended to reduce the need for separate trips into the borehole and to support flexible completion procedures.

Collaborations

The supplied information identifies Ron Dirksen and Kehinde Samuel Adesina as Keller’s coworkers. It does not specify their roles in the patent or the invention.

Conclusion

Mark Edward Keller’s patent describes a one-trip system that brings multiple well operations together, highlighting an engineering approach to more integrated oilfield completions.
