Abstract

This paper presents novel approaches and comprehensive field case examples on applying water chemistry in reservoir management and production. Systematic field water sampling and analysis, data integration, and water chemistry fingerprinting techniques are utilized for various important applications such as Original Oil In Place (OOIP) estimate, water source identification, prediction/prevention/management of oilfield scale and other water-related production/operation problems. Field case study examples show significant value creation achieved by utilizing water chemistry-based approaches. Results show subsurface water heterogeneity can significantly impact the calculation of OOIP, water sampling and analysis is critical to identify "unexpected" scaling risk at initial water breakthrough and monitor seawater breakthrough ensuring management/treatment in place as needed, systematic water data collection and integration and understanding can be used as a reliable/efficient/cost-effective approach to identify water source/water breakthrough from a new formation zone. Significant value creation was achieved for projects via our novel and systematic water chemistry-based approach discussed in this paper.
水化学在油藏管理和生产中的应用
本文介绍了将水化学应用于油藏管理和生产的新方法和综合的现场实例。系统的油田水采样和分析、数据集成和水化学指纹技术可用于各种重要应用,如原始含油(OOIP)估算、水源识别、油田规模预测/预防/管理以及其他与水有关的生产/运营问题。现场案例研究表明,利用基于水化学的方法可以创造显著的价值。结果表明,地下水的非均质性会显著影响OOIP的计算,水采样和分析对于识别初始水突破时的“意外”结垢风险和监测海水突破至关重要,确保根据需要进行管理/处理,系统的水数据收集、整合和理解可以作为一种可靠/高效/经济的方法来识别新地层的水源/水突破。通过我们在本文中讨论的新颖和系统的基于水化学的方法,为项目创造了显著的价值。
