Core analysis as a commercial service is introduced to the petroleum industry by Core Laboratories. The early work of James A. Lewis, Core Lab’s first President, on the determination of the permeability coefficient of a porous media became a guideline for those involved in controlled oil production. Core’s second employee, W. L. (Bill) Horner, conceived the summation of fluids method for measuring porosity by adding the oil and water content and void space in a core sample. He also patented the downdraft retort used in oil and water measurements and developed the method of injecting mercury into a sample to determine its void space.
