Abstract
The objective of this paper is to scrutinize the technical feasibility and performance of Nanofiltration technologies in sustainable water injection for Abu Dhabi National Oil Company (ADNOC)'s onshore oil reservoirs. It evaluates the efficiency and environmental impact of Nanofiltration, initially focusing on reservoirs with a production capacity of 1.8 million barrels per day, and later extending to 2.4 million barrels per day. A hybrid approach combining computational simulations and empirical data collection is used. Laboratory experiments evaluate Nanofiltration efficacy in filtering seawater to meet required quality standards for oil reservoir injection. Field data from ADNOC's existing operations serve as a baseline for comparative analysis. Findings indicate that Nanofiltration technologies demonstrate a high degree of efficacy in filtering seawater to the required quality standards for oil reservoir injection. The technology shows promise in reducing the environmental footprint by minimizing groundwater extraction. Economic evaluations, although not the primary focus, suggest that Nanofiltration could become cost-effective in the long run. Initial phases targeting reservoirs with 1.8 million barrels per day production have been promising, validating the technology's scalability. This paper introduces a rigorous technical analysis of Nanofiltration technologies deployed for water injection in oil reservoirs, using ADNOC's operations as a case study. For engineers and technical experts, the paper provides a deep dive into the technological aspects of Nanofiltration, backed by empirical data and computational models, offering a technical roadmap for adoption in similar settings.
