Scale Study: The Green Inhibitors For Silica Polymerization

This project is entitled The Green Inhibitors for silica polymerization aimed to identify and evaluate the efficiency of potential green inhibitors from natural extract to be compared with the commercial green inhibitor such as polyaspartate. This project generally has the purpose of providing the alternatives in mitigating the silicate scale in the reservoir which undergone ASP flooding recovery method. Silicate scale deposition during the ASP flooding is considered as the serious problem as it may cause severe damage to the reservoir as well as the equipment used during the production. There is no threshold scale inhibitor identified to completely prevent the silicate scale deposition. But, conventional scale inhibitor has been used to effectively prevent or delay the silicate scale formation for several years. Unfortunately, the usage of conventional scale inhibitor is not biodegradable and may harm the aquamarine environment which has led to the invention of green inhibitor. The usage of green inhibitor is to maintain the integrity of oil industry as well as to abide by the environmental regulations. In this project, several green inhibitors from plants have been identified such as Psidium Guava and Barley which have the inhibitory effects towards scaling. Therefore, experimental procedure is done to evaluate these potential green inhibitors as well the commercial green inhibitor to determine the efficiency of the inhibitors toward silica polymerization in brine solution. The proposed experimental method for this project is the static model test which illustrates the condition of the reservoir with the presence of the suggested green inhibitors. The objective of the experiment is to evaluate the efficiency of the green inhibitor by examining the efficiency of inhibitors with the prepared brine solution containing silica. The results of this project showed that the proposed green inhibitors have the inhibitory capability to delay the scale formation. But the overall process can be improved to enhance the results.
