Research: Mark's research was in conjunction with Dr. Kantzas. Mark was studying the deposition of asphaltenes in bitumen upon mixing with heptane. The induced deposition could then be studied under a variety of conditions mimicking well bore temperatures and pressures when asphaltene deposition could be a problem.
