With 40+ years of professional engineering experience, is a M.Sc. Petroleum. Engineering graduate, working in oilwell drilling operations. Drilling and completion projects have included deep, High-Temperature High Pressure (HTHP) exploration and development wells, directional wells, and horizontal wells in both conventional reservoirs and in unconventional shale plays in numerous basins throughout the world. Designed drilling and completion programs for extended-reach horizontal wells and multi-lateral wells with multi-stage fracture stimulations. Provided technical, managerial, implementation supervisory programs for various types of exploration and development wells in the U.S.: in Utah, Nevada, Colorado, Texas, Alaska, Ohio, Pennsylvania, North Dakota, Louisiana, Wyoming, and California; and internationally: in Africa, Asia, Australia, Europe, the Middle East, and South America. Assignments have included Drilling Superintendent, Drilling Engineer, Completion Engineer, Operations Engineer, Chief Engineer, Drilling Manager, and Project Manager. Also, recently served as consultant Drilling Manager for Halliburton Project Management, responsible for managing all HPM onshore drilling operations in North America. Consultant projects included horizontal wells in Volga-Ural basin of southern Russia; deep, HTHP exploration wells in the sub-Andean overthrust belts of northern Argentina, Bolivia, and Colombia; deep exploration wells in the Basque region of Spain; managed-pressure drilling operations and Sim-Ops operations for gas wells in various basins in the US Rockies; high temperature exploration wells in Nevada; HTHP horizontal gas wells in the Haynesville shale; 2-section and 3-section horizontal wells in the Williston basin; multi-rig operations in the Russian Arctic; and remote exploration wells in Australia, Kazakhstan, and Yemen. Engineering work included geomechanical modeling and wellbore stability studies and other engineering analyses; permitting; detailed well designs for complex wells; tendering and analyzing bid proposals; developing detailed drilling and completion programs; managing location and access road construction; planning logistics for remote operations; managing all phases of drilling/completion operations; implementing best drilling practices; supervising critical drilling/completion operations; and assessment of operations to optimize efficiency, safety, and economics.

With 50+ years’ experience, as a Professional Engineer, Petroleum Engineering Professor, Scientist and Energy Consultant worldwide, he is a Stanford PhD graduate and the Halliburton Distinguished Professor of Engineering at the University of Oklahoma. Over the decades Dr. Crichlow has researched the nuclear waste disposal processes and operations and designed, implemented and patented several systems for the safe, economical disposal of high level nuclear waste in deep geologic repositories, especially the concept and utilization of long lateral wellbores with specially designed and constructed waste capsules with effective radionuclide barriers and massive engineered barriers. He has currently more than 20 utility patents issued and patent applications in progress at the USPTO. He developed a high-temperature laboratory for the real-time analysis of fluid flow in porous media which was subsequently sold to USDoE . Consultant projects include major energy assignments in South America for the World Bank funding prior to international development of the pipeline systems in South America. Dr. Crichlow aided the Kuwaiti nation by designing, developing, planning, writing, managing and implementing their CONTINGENCY PLAN and their RECOVERY PLAN to rehabilitate the destroyed Kuwaiti oilfields after the oil-well fires. Dr. Crichlow made the feasibility study, reserves evaluation and engineered the injection scheme to maximize operations in the PEMEX $3-billion dollar offshore, 1,000,000 Barrel/Day, Cantarell Field Development and the associated Gas Injection program. As an engineer, he evaluated 29,000 projects for the FDIC. In drilling technology, he worked on innovative PDC bit designs, the downhole vortex generators and blowout control systems and evaluation of flow systems and on the major British Petroleum recent blowout problems in the Gulf of Mexico. Dr. Crichlow has an extensive background in solving major and complex engineering problems.
