Oil & Gas Process Simulation

Introduction:

Many of the decisions made by oil and gas companies rely on simulations of deposits, wells, infrastructure, and operations. Companies use oil and gas simulation and modeling software to create realistic representations of reservoirs, equipment use, and resistivity, as well as environmental effects. This type of software helps oil and gas companies predict exploration or production results, and assess risks that may impact safety and profitability.
