MFrac Suite (formerly Meyer) 3D reservoir modification simulation system software is a highly integrated software that combines the functions of field data acquisition, reservoir parameter analysis, single-well and multi-well full-well multi-stage multi-cluster fracture design, fracture optimization of multiple scenarios, production capacity prediction and fitting, economic evaluation, 3D visualization, etc. It is capable of designing and analyzing various types of fracture simulations such as slit-net fracturing, sand-added fracturing, acid fracturing, foam fracturing, fracture filling, end de-sanding, and so on. It is capable of designing and analyzing various types of fracturing simulations, such as fracture network fracturing, sand fracturing, acid fracturing, foam fracturing, fracture filling, end desanding and so on. Its unique and mature DFN algorithm shows strong superiority for shale, coalbed methane and tight sandstone oil and gas.
