After completing his PhD in petroleum engineering in 1989, Dr. Ivor R. Ellul served in executive positions for various companies in the petroleum industry. With his own company Knowledge Reservoir, Dr. Ivor Ellul focused on delivering consulting services to energy companies ranging from start-ups to small and large independents, to majors and super majors, and national oil companies. More recently, with CiSK Ventures he devotes his attention to new ventures in oil and gas exploration. One of the most recent developments in the industry relates to unconventional hydrocarbon deposits.
Drilling for unconventional fuel sources, such as shale gas and tight oil, is a complex process. Often, operators are forced to drill horizontally to get the most out of tight wells. A fracking process is also commonly employed to create cracks in the almost impermeable rocks and thus allow the oil or gas to flow more easily. As a result, drilling for conventional hydrocarbons tends to be more cost efficient than that for unconventional ones.
