Over the past 20 years, polymers have been utilized in oil and gas industries as drag reducing agent (DRA) to overcome pressure drop and optimize the flow capacity in water flooding system. Yet a new eco-friendly DRA extracted from organic materials (coconut residue) is introduced to replace polymers due to its abundance and ability to perform as effective as polymer in accelerating the flow in oil and gas systems. This research intends to describe the preparation process of CMC from coconut waste and then evaluate its effectiveness as DRA in water injection well. The result of injecting these chemicals in water injection well will reduce the number of injection wells by causing a significant improvement in the flow rate which will be able to push the hydrocarbon towards production column. At the meantime, the effect of DRA upon formation permeability is going to be investigated as well as the mechanical shear degradation of biopolymer. The effect of this new drag reducing agent extracted from coconut residue on formation permeability will be evaluated by using benchtop permeability system and observe if such permeability reduction can be induced. Mechanical degradation obstructs the implementation of biopolymer for turbulent drag reduction. In general mechanical degradation refers to the process in which the chemical chain is broken due to mechanical disturbance and result in losing biopolymer its practical usage as DRA. Thus, mechanical degradation is studied by exposing 0.5% and 1.0% solution of biopolymer to a high stirring speed and observe its influence on the viscosity of the solution with respect to time. The decrease of viscosity with time is an evident of mechanical degradation of biopolymer which is educed due to shear stirring.
