The project focuses on the diagenetic and pore network evolution of continental carbonates in Angola, combined with a characterization of diagenetic fluid chemistry and timing of fluid flow. By integrating data from outcrops and offshore reservoirs with the tectonostratigraphic context and paleoenvironmental position in the rift, the study will constrain the regional depositional, diagenetic and tectonic controls on reservoir quality. The regional view is possible through access to a large onshore dataset (samples, shallow cores, logs, outcrop mapping) and to a subsurface reservoir core, provided by BP and Statoil. Results of this study have direct application to South Atlantic reservoirs, but predictive rules are equally applicable to exploration in other rift systems.

该项目的重点是安哥拉大陆碳酸盐岩的成岩和孔隙网络演化，并结合成岩流体化学和流体流动时间的表征。通过将露头和海上储层的数据与裂谷中的构造地层背景和古环境位置相结合，该研究将限制区域沉积、成岩和构造对储层质量的控制。通过访问由BP和Statoil提供的大型陆上数据集（样品、浅层岩心、测井、露头测绘）和地下储层岩心，可以获得区域视图。这项研究的结果直接应用于南大西洋储层，但预测规则同样适用于其他裂谷系统的勘探。
