Horizontal Well Productivity Evaluation for Stress Sensitive Elliptical Reservoirs

Improved Oil and Gas Recovery, 2020
Well productivity model is one of the vital tools required to evaluate well performance. Most horizontal well productivity models are idealistic in nature, mainly developed for homogeneous reservoirs and conventional reservoirs, and ignore the influences
