Enhanced oil recovery (abbreviated EOR) is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field. Enhanced oil recovery is also called improved oil recovery or tertiary recovery (as opposed to primary and secondary recovery). According to the US Department of Energy, there are three primary techniques for EOR: thermal recovery, gas injection, and chemical injection.Sometimes the term quaternary recovery is used to refer to more advanced, speculative, EOR techniques.Using EOR, 30 to 60 percent, or more, of the reservoir's original oil can be extracted, compared with 20 to 40 percent using primary and secondary recovery.


There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection.

    • H2S Scavenger

      In the natural gas, there are generally contains the H2S gas, which is a high risk poisonous gas, not only harmful to human health, pollution environment, but also to the transport pipeline and related equipment. Therefore, it is necessary to take the desulfurization processingto improve the quality of natural gas,and up tothe relevant standards. For offshore platform mining operations, the method thatusingthedirect injection of liquid desulfurization agent on...


    • Xanthan Gum


      Xanthan Gum is a high molecular weight polysaccharide produced by viscous fermentation. Its unique functionality compared to other commercial polysaccharides is provided by the Actual structure of the xanthum gum molecule. It is widely used as a thickener and stabilizer. Oil drilling and exploitation grade xanthum gum is specially produced mud additives for Oil drilling and exploitation. Being environmentally friendly and high efficiency mud additives, Oil...


    • BPPCA

      In the process of drilling, completion and stimulation, the selection of the polymer in the operation is difficult to be degraded, and often cause damage to the polymer. Because the polymer can not be fully degraded, and the formation of the mud cake will cause the damage to the diversion capacity of the support agent filling layer and  the original permeability of th...


    • Oil-displacement Polyacrylamide

      Oil-displacement agent, when the oilfield cones into tertiary recovery period, single waterflodding oil displacement method, since its flow rate is higher than that of the underground crude oil it drives, will greatly reduce its spreading efficiency and increase water consumption, and greatly increase the water content of the crude oil collected. In addition, nonuniformit...


    • Surfactant

      During the fracturing and acidifying operation of oilfield, the working fluid should be discharged out of the ground rapidly and completely after operation to avoid secondary pollution to the formation and increase output and injection. However, the residue liquid cannot be discharged completely as the surface tension is usually too high; when cleanup additive is added, the surface tension can be lowered efficiently, the interfacial activity can be improved, and this is fa...


    • Sodium Polyacrylate

      Sodium polyacrylate is a water soluble straight chain polymer, named as PAAS, and the structural formula is. It possess a series of excellent features such as strong heat resistance, high temperature resistance (~300oC), good viscosity and quality stability and so on. Ranged a broad molecular weight from hundreds to tens of millions for sodium polyacrylate, there is a very close relationship between the molecular weight of sodium polyacrylate and its properties, such as th...
