Abstract
Summary
We present an in-depth study performed in the Jubarte's reservoir (Campos Basin, Brazil) to demonstrate that marine CSEM could complement seismic in reservoir-monitoring applications.
We show that 4D CSEM could play an important role in improving our knowledge of reservoir structure and properties. What lies beyond its adoption is its perceived value and cost relative to seismic, lack of definitive case studies and most significant, lack of game-changing developments and investments in new concept 4D acquisition systems.
We conclude that transformation of marine CSEM into an accepted and cost-efficient integrator to 4D seismic requires major technological enhancements reassessing instrument design, resolution and deployment to operational efficiency.
As demands for deep-water reservoir monitoring become more challenging, seismic – EM ocean bottom technology could increase the confidence in 4D and the rock physics behind it. Planning for 4D integrated seismic -EM early in the field's life may help minimize the number of initial development wells and permit early field intervention and upgrades to the depletion and reservoir-management strategies.
In the current capital constrained market, development funding for 4D seismic – EM game-changing technologies waiting to happen, could be difficult to secure. But we are optimistic as we foresee the potential and needs.
