ERCE’s reservoir engineering group combines a wide range of industry techniques and our team’s experience to maximise the use of available data during reservoir engineering studies. We endeavour to present our clients a clear understanding of their assets, while appreciating the limitations and uncertainties involved in the analysis.

Integrated Model Design

ERCE has a specialised team for integrated oil and gas reservoir modelling and we begin with the end product in mind. We ensure that all key contributors, including geoscientists and petrophysicists, are actively involved throughout the model building process. We consider this essential input, as our modelling projects benefit at each stage from the inputs of different specialties.

3D seismic control of facies distribution is provided, where possible, by our seismic reservoir characterisation group, enabling as much deterministic constraint as possible to be brought to bear during modelling. Where appropriate, a multi-realisation probabilistic approach is adopted to capture the range in reservoir uncertainty. Integration of well test and production data is utilised to make certain that reservoir heterogeneity is modelled at the appropriate scale. By paying close attention to the modelling of the key elements affecting reservoir performance, we make sure that the geomodel allows subsequent dynamic simulation models to accurately reflect reservoir behaviour.

 

Oil and Gas Reservoir Simulation

ERCE’s reservoir simulation team has decades of experience in auditing and constructing dynamic simulation models. Besides the extensive hands on experience, the team includes PhD specialists with publications on numerical simulation, CO2 sequestration and fracture simulation modelling.

We commercially use several modelling platforms including ECLIPSE, tNavigator and CMG, in addition to a variety of pre and post processing software packages. The team also tests and develops numerous in-house add-ons for multi-realisation runs and live integration between the simulators and the surface network models or other commercial constraints.

ERCE uses the most comprehensive PVT modelling software packages available, with experienced staff in charge of interpreting and integrating the PVT lab experiments and taking the tuned equations all the way through the dynamic modelling.

Our team has successfully built simulations for FDP submissions and for ongoing field operations, in a variety of challenging reservoir types. Examples of our work include:

  • Black Oil Simulation Modelling
  • Compositional Simulation Modelling
  • CO2 Sequestration Simulation Modelling
  • Fracture Simulation Modelling
  • Multi-Stacked Reservoir Modelling
  • Enhanced Recovery Optimisation Modelling
  • Multi-Realisation Assisted History Matching
