Use of pore network models to interpret laboratory experiments on vugular rocks

Laboratory evaluation of recovery behavior in vugular rocks is unreliable because pore features are relatively large. 3-d Computed Tomography (CT) images of the porosity and of multi-rate waterfloods in a vugular sample show that conventional analysis is inadequate. Through parametric studies, we determine whether our large pore network models contain characteristics observed in the core floods. We then calibrate our models to laboratory inputs to improve quantitative interpretation.
