Abstract

Oil spills in coastal areas are a serious environmental issue that can cause damage to marine ecosystems, water pollution, and economic losses for fishing communities. This community service project aims to enhance fishermen's understanding of the negative impacts of oil spills and to provide practical skills and knowledge regarding oil waste management. The approach used includes training on the use of absorbent tools, binding chemicals, and localization technologies to handle oil spills. Additionally, the project introduces environmentally friendly technologies to reduce the risk of oil leaks or spills from fishing vessels. The project results indicate a significant increase in the knowledge and skills of the participating fishermen regarding oil waste management. Further discussion reveals the importance of implementing comprehensive coastal area management strategies to prevent and mitigate oil pollution. In conclusion, this project not only successfully achieved its goal of enhancing fishermen's capacity but also offers a replicable model for similar programs in other coastal areas. Therefore, active participation from fishing communities and continuous support from various stakeholders is essential for environmental sustainability and the well-being of coastal communities.

Abstract

The behavior of petroleum reservoirs is inherently complex, making it challenging to determine their performance for both single-fluid and multiphase production systems. To accurately estimate the recovery reserves of a reservoir, a comprehensive understanding of its geometry and internal flow characteristics is essential. Numerical simulation serves as a fundamental tool for reservoir engineers, offering an efficient and reliable method to predict reservoir mechanisms, evaluate pressure variations, and estimate in-place hydrocarbon yield. This study employs mathematical modeling concepts and numerical techniques to analyze the dynamic behavior of petroleum reservoir systems. A flow model based on Partial Differential Equations (PDEs), specifically the diffusivity equation for unsteady-state fluid flow in porous media, is developed and applied. The diffusivity equation is discretized and solved mathematically using the explicit finite difference method to approximate pressure distribution over time and space. The primary objective of this research is to investigate and analyze the pressure distribution that governs reservoir performance under varying conditions. Sensitivity analyses are conducted to evaluate the influence of grid spacing, time step, hydraulic diffusivity, and boundary conditions on pressure reservoir behavior within a Cartesian grid for a one-dimensional, single-phase reservoir. The findings are expected to provide insight into the relationship between reservoir properties and fluid dynamics, supporting improved prediction of reservoir behavior. Ultimately, this research contributes to the optimization of petroleum production strategies and enhances the understanding of reservoir engineering processes through quantitative simulation.
