DFIT Interpretation

3:29 Hours
The DFIT Interpretation course provides comprehensive training on Diagnostic Fracture Injection Tests used primarily in low permeability formations to estimate stress, pore pressure, and permeability. Developed from the collaborative URTeC-2019-123 procedure, the course combines modeling, analytical techniques, and real field data interpretation. It covers fundamental physics behind DFIT data, including fracture behavior and pressure transient response, followed by practical methods for estimating key reservoir parameters. The course also highlights differences from conventional well test analysis and improvements over previous DFIT methods. Participants will gain insights backed by recent research and real-world validation to enhance their completion and reservoir engineering practices.
