2021 3Q4Q SEG Distinguished Lecturer
Recent advances in seismic reservoir characterization and monitoring
The seismic industry has seen significant technological changes over the past few years. In this lecture, I will be discussing three of these developments and focus on what works and why. The first topic will be using advanced seismic data for improved reservoir characterization and monitoring. Here I will show how joint PP/PS inversion can improve shear impedance estimation, which can impact both exploration success, and when applied to time-lapse seismic data, development well planning. Then I will discuss the limitations of azimuthal anisotropy estimation from P-waves. The next topic I will discuss is an amazing new technology; fiber optics. Fiber optics sensing has been rapidly building up in our industry as a key technology for sensing away from a well, as well as understanding well completion operations and production surveillance. I will go over an example of its use as a high-repeat seismic VSP for hydraulic fracture characterization of individual fracturing stages. For the final topic, I will discuss perhaps the most important issue facing our industry, carbon sequestration, and value-driven subsurface applications. Here I will go over the forces requiring carbon reduction and why sequestration for EOR is potentially the best path for the energy industry and a reasonably well-posed problem for geophysical monitoring.
