FracMan

FracMan® Reservoir Edition, an integrated application for fractured reservoir model construction, analysis, and simulation. FracMan Reservoir Edition allows geologists and engineers to seamlessly integrate geological, geophysical, and well-test data into a single quantitative discrete fracture network model. The resulting models can then be used by industry-standard applications to evaluate well drilling location and completion design, gel and grout treatment design, estimate original oil-in-place (OOIP), and compute estimated ultimate recovery (EUR).
