One of the most basic roles of any Petroleum Production Engineer is to estimate the flow from the reservoir into the wellbore. The complex variety of inflow geometries, reservoir properties, and near wellbore conditions traditionally have made such estimations difficult to do in the field without pulling out a pad of paper and a calculator. Reservoir is designed to make these calculations effortless. Combining numerous cutting edge inflow models and correlations, Reservoir will come in handy anywhere from the rig to your desk and beyond.
