Abstract

Water coning can occur in old wells or new wells. There are several methods that are often used to overcome the problem of water coning and high water cut in the oil and gas industry, namely by reducing the production rate below the critical flow rate, recompletion, water shut-off, chemical polymer, and dual completion. In this study, researchers used the chemical polymer method to overcome the problem of water coning and high water cut because it is considered cheap and easy to apply. The chemical polymer method is often used to treat water coning. This method is widely applied in oil wells because it is easy to apply. This chemical polymer is injected into the production well by adding an agent to the formation water to increase its viscosity in order to prevent the mobility of the water from being produced. Synthetic polymers are commonly used for water coning problems, but negative impacts can occur on the surrounding environment. The highest yield of cassava peel (NaCMC) synthesis in increasing oil viscosity was obtained by adding 45% sulfuric acid with the addition of 90% yield. The result of the highest viscosity test of cassava peel biopolymer was obtained at a concentration of 15,000 ppm with a viscosity of 3.96 cp. From the results of the biopolymer FTIR test, the cassava peel obtained the functional groups OH,C-H,C-O,C=O
