In most oil fields, only a fraction of the oil can be produced by natural reservoir pressure and by conventional methods such as pumping. Often, as much as 75 percent of the oil can remain in a reservoir after primary recovery. The remaining, or residual, oil can be recovered only by using recovery methods that restore pressure and fluid flow in underground formations through the introduction of water, gas, chemicals, heat, or a combination of these, into the reservoir. These recovery methods are often referred to as enhanced or improved recovery methods. A further distinction is made between secondary recovery methods, which often refers to pressure maintenance methods, and tertiary recovery methods, which often refers to methods that improve oil displacement. The major methods of enhanced oil recovery (EOR) are: water flooding gas injection chemical flooding thermal recovery Gas injection may be immiscible or miscible (unable or able to mix with oil). Water flooding (the most widely used recovery method) and immiscible gas injection are pressure maintenance methods and are generally used in secondary recovery. Thermal recovery lowers the viscosity of the
into the reservoir.
Cisne’s EOR method, CavaChem, consists of an injection tool and a patented chemical, EMC CavaChem uses cavitational waves and EMC to achieve optimal penetration throughout the production zone. CavaChem creates cavitation by accelerating a EMC fluid stream through a restricted area, creating a reduction in pressure. The molecules of the liquid in the low pressure zone are literally pulled apart by force and changed into gas bubbles. Downstream the fluid undergoes a deceleration process resulting in a reveral o fthe energy and raising the pressure above the vapor stage. The bubbles can not exist at the increased pressure and are forced to collapse or implode. These implosions are the most effective part of the cavitation process and causes increased penetration of the EMC. This action reduces the interfacial tension of the well, improves permeability and Enhances Oil Recovery. Because each well is different, it is essential to analyze the well characteristics, including formation, depth, prior chemical use , etc., to determine the proper treatment protocol.
The Cavachem Process is: Effective - Practical - Economical - Environmentally Safe
