Process Simulation in Oil & Gas

Introduction:

Important decisions within oil and gas companies require reservoir, well, and other infrastructure and operations simulations. Advanced oil and gas process solutions and simulation training help them devise precise reservoir models, equipment performance models, resistivity models, and models of environmental influences.

This software allows companies to make predictions about exploration and production activities, along with risk analysis that may hinder the safety and profitability of these operations using high-end oil and gas process technology.
