Solver Technology

ReO^® software's optimizer technology is based on sequential linear programming. Unlike many surface production network software products, it simulates and optimizes the network simultaneously. Simulation determines the pressures, temperatures and flow rates within the production system while optimization determines the most economic production strategy subject to engineering and economic constraints. The economic modeling capability inherent within the program takes into account revenues from hydrocarbon sales in conjunction with production costs to optimize the net revenue from the field

ReO software offers a wide variety of objectives–maximize, minimize, bounds and target, for pressure, flow rate and H₂S and CO₂ concentrations. Users can set these objectives at practically any point in the network. Even when operational constraints and user-defined targets conflict, the optimized solution will honor the operational constraints as far as physically possible (i.e. if required the optimizer breaks the user-defined objectives and warns user accordingly; however, the algorithm always honors the physics of the process).

Scalability–ReO software can optimize networks of thousands of wells in a robust and efficient manner.

Topological complexity–any degree of complexity can be handled by the software including loops and branches as well as distribution and injection networks.

Total system modeling–injection and production networks can be solved and optimized simultaneously.

The unique network trimming functionality aids users in focusing the prime part of the network. The intelligent scanning algorithm identifies sections of the network which are not accessible due to blocking of various valves and disables these sections for optimization calculations. The hot start feature allows users to start optimization calculations using the results of the previously optimized solution.
