..., and to generate production forecasts in support of well interventions. The inflow and outflow parameters are directly related to well-known reservoir and well properties, and can be calibrated against common well surveillance and production data. By adopting this approach, engineers develop a better appreciation...

... Steam is injected in the bottom layer. Heat propagates upwards helping lower the viscosity in the top layers which are then water-flooded. Needless to say, the physics behind such recovery process is not trivial. In this paper, production forecasts for this interesting reservoir will be made...

... for probabilistic uncertainty analysis of production forecast. Although DoE-based AHM is straightforward in concept, it can be misused in practice because the workflow involves many statistical and modeling principles that should be followed rigorously. In this paper, the entire DoE-based AHM workflow...

... gradually, avoiding premature level elimination (minimizing convergence at an incorrect solution). In both phases, the matched simulation models presented similar production forecasts to the reference model. The 4D seismic data were included regionally with an acceptable increase in computation time...

... components, identification of pump requirements, production optimization and cost reduction. Analysis of these outputs leads to an improved understanding of field operation strategies, equipment selection and sizing, and production forecasts. The integrated model uses Inflow Performance Relationships (IPR...

... response to the pilot waterflood. A secondary independent analysis used an offset operator's Clearfork waterflood as an analog to generate a production forecast using dimensionless curves, and the results confirmed the numerical model forecast. The predicted reservoir response using both methods revealed...
