He started the company in 1988, after 10 years in the oil industry gathering experience in areas including research and development, sales and marketing, and drilling chemistry. Many of the laboratory techniques that he has developed, such as filter-plugging for WAT measurements, and the spectroscopic evaluation of asphaltene precipitation, are now widely used in the industry.
