COURSE DESCRIPTION: Understanding the properties of rocks is fundamental for a subsurface professional. This topic is covered step by step in clear detail based on the instructor’s practical industry experience over many field data applications. The course gives participants an understanding of how the rock frame, the fluids, and pore pressure impact the seismic response. The course also covers how to use wells logs and conduct well ties for seismic calibration and interpretation. Going from rock physics, to well logs, to well tie completes the fundamental knowledge needed to understand, interpret, and analyze seismic data and is key to drilling successful wells. This is a practical course covering theory, practical learnings, key pitfalls, overview of key papers, and practical exercises.
LEARNING OUTCOMES:
- Understand how rock physics is applied in the exploration and production of hydrocarbons, including reservoir characterization and monitoring.
- Learn how to use rock physics principles to interpret seismic data and create subsurface models.
- Be able to evaluate fluid and pressure changes on rocks when analyzing seismic data.
- Understanding key well logs and how to use them in seismic interpretation.
- Understanding why and how to conduct a well tie to seismic data.
- Be familiar with pitfalls associated with rock physics and well data.
- Improve the ability to communicate findings and interpretations effectively between subsurface disciplines and with management.
