L. Brun Hilbert, Jr., Ph.D., P.E.

Principal Engineer

Mechanical Engineering

Professional Profile

Dr. Hilbert has been consulting at Exponent since 1996 in the fields of mechanical and petroleum engineering, with special applications to engineering mechanics and geomechanics. He has worked in the petroleum exploration and production industry for 30 years.

Dr. Hilbert has expertise in stress analysis, solid mechanics, fluid mechanics, heat transfer, and structural component design. In the area of petroleum engineering, he has expertise in oil and gas well design and integrity, hydraulic fracturing, well production and wellhead equipment, well stability and sand production, well stimulation, drilling mechanics, petroleum rock mechanics, reservoir geomechanics, fixed and floating offshore platforms, and gas and liquid hydrocarbon storage in solution-mined salt caverns and hydrocarbon formations. In the area of geomechanics, Dr. Hilbert has expertise in evaluating the structural integrity of oil and gas wells in compacting or deforming reservoir rocks, in the stability of underground storage structures and nuclear waste repositories and he assists clients in failure analysis involving soil-structure interaction, including pipelines. Dr. Hilbert has highly specialized expertise in the structural integrity and leak resistance of the threaded connections used to join high-pressure pipe. He has conducted failure analyses of steel, rubber, and plastic structures.

Prior to joining Exponent, Dr. Hilbert was employed as an Engineering Specialist for Exxon Production Research Company.
