Tendeka wins inflow control contract for SAGD wells in Canada
March 1, 2013
Tendeka have secured contract wins for Cyclic Steam Stimulation monitoring, AICD in SAGD and software for reservoir interpretation in Canada.
Our AICD device, FloSure, can be used to control injection from the entire length of a horizontal well drilled in an oil reservoir.
Installing FloSure™ AICDs means that a pressure drop can be created between the reservoir and the completion liner. The resulting choking effect creates a back pressure on higher quality sections of the reservoir, allows tighter sections to flow and thereby evens out the inflow profile from the well. The end result is delayed water breakthrough as a direct consequence of better coning control from the evening out of the inflow profile.
FloSure™ is a versatile tool. Designed to control gas production in low to medium viscosity oil wells, it also has applications for water control in heavy oil wells. The valve has been designed with one moving part and responds to the velocity of the fluid coming into the well. In situations with low viscosity gas the friction pressure is reduced, resulting in very high velocity that in turn ‘sucks’ the disc against the seat and thereby restricts gas flow. Conversely, when high viscosity oil is present, there is an increase in friction pressure. Consequently, the disc is pushed away from the seat and the oil flow increases.
Tendeka’s AICDs are most effective when increased zonal isolation is achieved. The Tendeka FloSure™ AICD, which is installed in every Flomatik or FloRight device, can be used in conjunction with FloSeal™ open hole packers or SwellFix™ swellable packers to achieve compartmentalization of the horizontal section. The horizontal drilling process allows for greater penetration of the length of the reservoir, resulting in greater recovery from the reservoir. Implementing Tendeka’s FloSure™ AICDs ensures maximum production is achieved over the life of the well.
