Effect of Drag Reducing Agent (DRA) In the Injection Well

The study of drag reducing agent (DRA) is increasing since researcher find on his study of the effect of mechanical degradation of polymer inside the pipe. Throughout the experiment, the studies conducted will assess the effectiveness of long chain polymer with a very high molecular weight DRA to increase the flow rate and reduce the frictional pressure cause by turbulence in the pipeline drop. This is the beginning of using the DRA in the oil and gas pipeline. In the oil and gas industry DRA is commonly used to increase the flow rate inside the pipeline. However, less study has done on the effect of DRA in the injection well. This project will discuss on the application of DRA in the water injection well and focusing on the effect drag reduction for polymers which is Polyacrylamide (PAM) at the standard temperature. In addition, difference injection rate is used to measure the performance of the DRA in the pipeline. Lastly, the correlation to find the optimize point between flow increase in the pipe and the permeability reduction in the reservoir. The results show performance of the DRA in the pipe of injection well. It is found that the best performance of DRA is at 2.5 gram in the 50 liters of water. After the correlation it is found that the optimize performance for DRA in the injection well and reservoir is when flow rate is at 30 liters per second.
