Production Decline Analysis for Vertical and Horizontal Wells

Salvo Global’s course is developed to address three main issues. It is designed to show the different forecasting tools used to forecast oil and gas reserves. Accurate forecast is mandatory for production operations, facilities design, well design and configuration and economic evaluation of oil and gas investments. The course involves extensive problem sessions in which the participants gain hands-on experience with forecasting real life production data using various methods. The limitations of the methods are presented to make sure that the participants pick the correct method to use in their respective situation. Time is also dedicated to generating probabilistic production forecasts (P10, P50 & P90) and building Excel models to forecast production.

The course also shows tools that can be used to diagnose reservoir problems. Well test analysis results are typically used to identify any reservoir anomalies such as faults, distance to fault, dual porosity system, wellbore storage and so on. Performance forecasting methods such as PI, IPR are also used.

Decline curve analysis in conventional and unconventional reservoirs. How decline curves and well test data can be used to diagnose reservoir anomalies.
