Abstract:
PI (Productivity Index) degradation is a common issue in many oil fields. Faster
production declines than initially forecast were observed in numerous deep-water assets.
The work has identified seven relevant decline mechanisms of which the failure of the
rock and the execution of the completion are significant factors impacting PI Decline. To
obtain a reliable production forecast, it is critical to include rock, well and completion
attributes into the forecast. This requires the inclusion of a coupled reservoir and
geomechanics simulator as well as a detailed representation of the completion and its
associated flow patterns. A large degree of uncertainty exists around the associated
parameters for each of these components. This uncertainty lends itself well to a machine
learning approach given the large number of variables and the need to create multiple
realizations of the history match to create more reliable production forecasts. The
presentation will highlight the damage mechanisms associated with PI Decline. The
presentation will also provide a methodology for creating a coupled simulation that utilizes
machine learning to history match and produce reliable production forecasts.
Incorporating geomechanics, completion description and near wellbore flow patterns
enhances production forecasting by providing better estimates for initial and well life
skins.
