Optimisation of gathering system against constraints:
- Fast and robust Global Optimisation algorithm using non-linear programming (NLP) which has been recognised in the industry as best in class.
- Wellhead chokes can be set, compressors and pumps optimised, and gas for gas lifted wells allocated to maximise production
- Multiple Flowlines
- Multiple Separators
- Unlimited number of nodes – wells, reservoir, etc.
- Field optimisation studies with mixed systems (ESP, GL, Naturally Flowing, PCP, Jet and Rod Pumps)
- Optimise production forecasting
Pipeline Flow Assurance Studies
- Models injection system performance, using MBAL or other numerical reservoir models
- Advises on wellhead chokes settings to meet reservoir management targets
Fully Compositional from the Reservoir to the Process side
Easy to use graphical interface for drawing system network (using icons for separators, compressors, pipelines, manifolds and wells, inline chokes and reservoir tanks)
For existing reservoirs, MBAL provides extensive matching facilities. Realistic production profiles can be run for reservoirs with or without history matching.
Reservoir Engineering Tool
- Material Balance
- Monte Carlo Simulator
- Decline Curve Analysis
- 1D model
- Tight Gas
This incorporates the classical use of Material Balance calculations for history matching through graphical methods (like Havlena-Odeh, Campbell, Cole etc.). Detailed PVT models can be constructed (both black oil and compositional) for oils, gases and condensates.
Furthermore, predictions can be made with or without well models and using relative permeabilities to predict the amount of associated phase productions.

PROSPER can assist the production or reservoir engineer to predict tubing and pipeline hydraulics and temperatures with accuracy and speed. PROSPER’s sensitivity calculation features enable existing well designs to be optimised and the effects of future changes in system parameters to be assessed.
PROSPER is designed to allow building of reliable and consistent well models, with the ability to address each aspect of well bore modelling viz; PVT (fluid characterisation), VLP correlations (for calculation of flowline and tubing pressure loss) and IPR (reservoir inflow).
By modelling each component of the producing well system, the User can verify each model subsystem by performance matching. Once a well system model has been tuned to real field data, PROSPER can be confidently used to model the well in different scenarios and to make forward predictions of reservoir pressure based on surface production data.
With PROSPER detailed flow assurance can be studied at well and surface pipeline level. PROSPER provides unique matching features which tune PVT, multiphase flow correlations and IPR to match measured field data, allowing a consistent model to be built prior to use in prediction (sensitivities or artificial lift design).
