Abstract

One method to further enhance oil production is through tertiary recovery, also known as Enhanced oil recovery (EOR). The EOR method can increase production from wells by up to 75% recovery. One of the EOR technologies that has been applied for more than 50 years in the petroleum industry is polymer injection, which has proven effective in improving oil recovery. The objective of this study is to obtain an efficient polymer with good compatibility and viscosity. This research analyzes the compatibility and viscosity characteristics of Xanthan Gum (XG) polymer solutions and a mixture of Xanthan Gum with Cyclea  barbata Miers (CHXG) in formation water with a salinity of 11,000 mg/L. Compatibility tests were conducted at concentrations of 1,000, 2,000, and 3,000 mg/L to determine the solubility of the polymer in formation water. The results show that both types of polymers have good compatibility, indicated by the absence of precipitation and the formation of clear and homogeneous solutions. Viscosity tests were carried out at room temperature and at elevated temperature (70°C) to evaluate the effect of temperature on the rheological properties of the solutions. The XG polymer exhibited a decrease in viscosity at 70°C, with the highest reduction of 24.3% at a concentration of 3,000 mg/L. In contrast, the CHXG polymer showed a significant increase in viscosity at high temperature, with the highest increase reaching 53.49% at the same concentration. These results indicate that the addition of Cyclea  barbata Miers can enhance the thermal stability and viscosity performance of the polymer under reservoir conditions at 70°C, whereas the use of Xanthan Gum alone results in a decrease in viscosity at the same temperature.

Abstract

The availability of clean water is a crucial issue in Jatimulyo Village, South Lampung Regency, particularly during the dry season. Residents face difficulties accessing water sources due to a limited understanding of the subsurface groundwater potential. In response to this problem, a team from the Sumatra Institute of Technology (ITERA) conducted a community service activity aimed at mapping this groundwater potential. This activity utilized the geoelectric resistivity method to identify subsurface structures and determine the locations and depths of potential aquifers for drilled wells. In its implementation, the team collaborated with the local village government and involved participants from the Geophysical Engineering and Petroleum and Gas Engineering Study Programs. In addition to technical surveys, the team also conducted a socialization of their findings and provided education on groundwater utilization. This event, attended by residents, local neighborhood (RT) heads, and village officials, highlighted the importance of proper aquifer identification, well maintenance techniques, and strategies for ensuring water resource sustainability. This initiative received positive appreciation from the village head and residents, who hope the results of the ITERA study can provide a concrete solution to address the challenges of clean water availability in their region.
