It takes a businessman-technocrat like Roger Kazanowski to recognize that oil extraction is an inefficient process that can benefit from technologies that boost oil extraction to its maximum levels. And no less than Chevron VP for global exploration Robert Ryan agrees when he said that one area of “discovery” that can determine the future world energy levels lies in efficient oil recovery.
Few people understand that the oil extraction has at least two stages. Roger Kazanowski has explained that the first stage called the primary recovery stage is when the oil naturally gushes forth. This happens when the oil well is first put into commercial production as the earth’s internal pressure built up in these vast oil reserves pushes 10% to 40% of the oil to the surface on its own. This can last for years or decades during which reservoir pressure gradually declines until it goes zilch and it now becomes necessary to initiate secondary recovery. This time, the oil needs some push and this is done with the help injecting water (waterflooding) or chemicals (CO2) to generate reservoir pressure to push oil to the surface. Typical secondary recoveries can result in additional 15% to 45% of the original oil reserve volume estimates. Many of the oil wells discovered in the middle of the 20th century are already in the secondary recovery stage.
This is where the technology behind the PowerWave product championed by Roger Kazanowski comes in. He sits in the board of the Wavefront Technologies Solution, Inc which has developed and now markets the product to oil companies. The technology also uses the same waterflooding principle but enjoys a patented method that increases the water injection rates for a more effective displacement of oil without increasing the well pressure. The process delivers a more cost effective way to generate secondary oil recoveries and is considerably cheaper than the modern method of using CO2 flooding while being more environment-friendly. There are now about 100 oil fields in various companies in North America using the process and have enjoyed a 10% to 20% recovery rate. Wavefront is out on a crusade to bring the technology to more oil wells. Its latest customer is the Calgary-headquartered Encana Corporation, one of North America’s largest natural gas producers.
