Kuwait Case Study: Integrated-Reservoir-Management Approach Offsets Effects of Reservoir Heterogeneity, Injectivity Challenges, and Delayed Waterflood

摘要

The Upper Burgan is a muitilayered reservoir in the Sabiriyah field of northern Kuwait, currently undergoing the initial phase of waterflood development. The reservoir is highly complex with respect to reservoir heterogeneity, connectivity, and structural compartmentalization. Early waterflood performance was too poor to achieve the targeted injection rates. Detailed channel mapping enhanced the subsurface understanding to add value to the ongoing drilling, production, and injection plans. The inte-grated-reservoir-management (IRM) approach, with a strategy for depletion and pressure support for each segment, increased short-term production and is sustaining the rates. The current and short-term drilling plans target reservoir segments with higher pressures for well placement.
