Determination 188bet vietnam contribution proportion 188bet vietnam injection wells in oil production by interwell tracer method using partitioning organic compounds from crude oil

Waterflooding is one 188bet vietnam the most common secondary oil recovery methods because 188bet vietnam its economic efficiency. In case where many injection wells contribute to the oil recovery process 188bet vietnam a production well, contribution proportion will be an important parameter for management 188bet vietnam water injection. Besides the well-known Interwell Tracer Tests using artificial tracers injected into the reservoir, the method 188bet vietnam using partitioning organic compounds in crude oil as Natural Partitioning Interwell Tracers (NPITs) shows a great potential for evaluating the contribution proportion 188bet vietnam injection wells in oil extraction process. The paper presents the research results to illustrate an idea 188bet vietnam using NPITs for calculation 188bet vietnam the contribution 188bet vietnam injection wells to a production well in homogeneous single-layered reservoir on UTCHEM simulation data with Five-spot model and Direct-line model. The results showed that the calculated values 188bet vietnam contribution proportion are different from modelling values between 1 - 2%.
