Abstract

Rapid-response reservoir modeling starts with the simplest model to obtain all pertinent reservoir information: boundaries, volume, skin, drive mechanism, porosity, permeability, flow barriers, analysis of the seismic data, quality of the petroleum, the liquid & gas composition/mix, etc. Traditional modeling workflows are often best characterized by one-way data transfers from the geologist/geophysicist side to the engineering side. Besides, a highly collaborative, multidisciplinary process must use a “continuous improvement loop” to converge on the solution.

Steamline methods are computationally much more efficient than the finite difference. Steamline methods give intuitive depiction of fluid flow due to their visualization capability. Some important applications are included: Volume calculations for reservoir swept areas; rate allocation and pattern balancing; flooding; modeling tracer flow.
