The study of the Potential of Nano-Scale Biopolymer Extracted from Coconut Husk as Drag Reducing Agent (DRA) in Water Injection Well

Drag reducing agent (DRA) is widely used as an additive to reduce the pressure drop in the pipeline system, thus will increase the fluid flow capacity. Whereas, water injection system is a secondary recovery method used to increase the reservoir pressure by injecting water into the reservoir through a number of injection wells. The DRA can be used to increase the performance of water injection system by reducing the pressure drop along injection wells. The synthetic polymer is widely used in the industry have raised an environment concern as it biodegrade very slowly, consequently it will bring harm if the usage is in excess. Hence, this project focuses on using environmentally friendly polymer DRA extracted from organic materials. In this study, grated coconut residue (CR) is used as biopolymer such as Carboxymethylcellulose (CMC) to produce the DRA. The CMC will be extracted from CR by synthesizing the cellulose under the alkali-catalysed reaction with monochloroacetic acid.
