Field Production Modelling and Forecasting with GAP and MBAL (BACIPS01LIC1)

  • 1 dayLicense period: 1 Month Course Fee: 140 EUR


This short, intense course covers the key concepts behind surface network modelling and forecasting using GAP and MBAL. Topics include building a new oil network model, running sensitivities on pipeline diameter, adding constraints and optimising gas lift and ESP wells systems. Field production forecasting involves adding a reservoir model to the surface network model. Topics include running a prediction and viewing the results, adding a water injector and adjusting well timing to achieve an optimum oil production plateau rate. We also evaluate the effect on recovery factor of converting wells to gas lift and ESP. 1 day classroom equivalent course. Discover the Baobab micro-learning method – studying at your own pace, in your own time. IChemE accredited course (7 CPD hours).
