Abstract
This article presents a practical, data-driven approach to improving oil recovery
from mature, heterogeneous clastic reservoirs. The focus is on the operational use of
surveillance data (production logs, tracers, pressure measurements) and updated
sedimentological concepts to continuously refine the reservoir understanding. It details
how revised parameters, such as sand body connectivity and permeability contrasts,
directly influence the mapping of remaining oil saturation (ROS). Based on updated
dynamic models, practical recommendations are formulated for conformance control
in waterflood projects and the targeted placement of infill wells. The paper
demonstrates that a systematic model-update practice can significantly improve project
economics through increased well success rates and reduced water handling costs,
without the need for massive capital investment.
