This course provides a comprehensive review of horizontal well applications, including Multi-Stage Fracturing of Horizontal Wells (MFHW), design sensitivity analysis, and production and reserves forecasting (P10, P50, P90). Related topics include the application of Pressure Transient Analysis (PTA), Rate Transient Analysis (RTA), and Diagnostic Fracture Injection Tests (DFIT). The course also addresses waterflooding and gas injection strategies in both conventional and unconventional reservoirs, supported by case studies and numerical modeling examples.

The program delivers in-depth technical background and state-of-the-art tools required to maximize the performance of horizontal wells. Practical examples demonstrate how candidate wells are selected and designed through multidisciplinary collaboration to optimize both technical outcomes and economic returns. Methods for predicting well performance—such as expected production rates, drainage area, and fluid coning behavior—are explained through class exercises.

Optimization of multi-stage fracturing is covered in detail, including determination of the number of fracture stages, stage spacing, fracture size, and identification of “sweet spots.” Advanced software tools are used to illustrate these concepts. The course also examines well test interpretation techniques, highlighting the value of mini-frac (DFIT) testing in improving fracture design.Finally, the challenges of reserves estimation in tight and unconventional reservoirs are addressed using advanced decline curve analysis and probabilistic methods. Comprehensive course notes are provided as a valuable reference.
