Successful Application of the Key Well Concept to Enhance Formation Evaluation

Dr. Maclean O. Amabeoku
President, Laurel Energy & Environmental Services, Inc.


A methodical approach to acquiring data from key wells to calibrate petrophysical models has proven effective in formation evaluation programs. In the key wells, extensive logging, coring and fluid sampling programs provide the data used to develop better predictive models for water saturation, lithology, porosity, and permeability.

Case studies show how the drilling fluid, coring and logging programs are designed to provide optimal conditions for obtaining good core and logs. In oil fields, key wells are cored with oil-base-mud. The cores are carefully preserved in the field, CT scanned, and then sampled for geological and petrophysical analyses.

This strategy of using data from key wells has enhanced formation evaluation programs. Significant benefits include reduced uncertainty in determining hydrocarbon pore volumes; improved integration of geological and engineering data; and enhanced static and dynamic reservoir models.


Dr. Maclean Amabeoku is President of Laurel Energy and Environmental Services, Inc. In this position, he leads a team of accomplished professionals in petroleum engineering, process engineering, environmental remediation, course development, and academia who have pooled resources to offer a broad range of services to the oil and gas industry.

Until June of 2016, Maclean was SCAL Advisor and Coordinator of Special Studies in the Reservoir Description & Simulation Department at Saudi Aramco. In that capacity, he designed and directed: special core analysis data acquisition programs for reservoir simulation and field development; improvement of petrophysical models to reduce uncertainties in formation and reserves evaluations; integration of core and log data for comprehensive petrophysical evaluation; and high resolution imaging and computational rock physics methodologies to estimate flow and pore scale properties. He is widely published in these areas of study.

Prior to joining Saudi Aramco, Maclean worked as research engineer at Occidental Research Corporation in California and as Project Manager at the Research Institute in Dhahran.

Dr. Amabeoku holds BS degree from the University of Kansas; and MS and Ph.D. degrees from the University of Southern California, Los Angeles, all in petroleum engineering. He is a member and technical editor of the Society of Petroleum Engineers (SPE).
