Abstract:
- Maximizing completion efficiency in fractured limestone reservoirs depends on targeting zones with both conducive geomechanical properties and open natural fractures. While the industry understands the theory behind effective hydraulic stimulation, execution requires an integrated map of the local horizontal stress field and fluid-conductive networks.
- This presentation delivers a comprehensive asset workflow by combining P-P azimuthal interval velocities and prestack amplitudes with engineering validation from ISIPs and microseismic data. I demonstrate how azimuthal prestack depth migration transforms properly acquired field data into actionable insights: utilizing azimuthal interval velocities to map minimum horizontal stresses and stress inequalities, and azimuthal prestack amplitudes to map aligned, fluid-flowing connected porosity.
- Featuring expanded findings that carry on from Lynn and Goodway (2020, Interpretation), this session bridges the gap between geophysical processing and reservoir engineering to deliver critical criteria for high-grading your next asset location.

Speaker Bio:
Heloise Lynn has worked the last 40 years as a consultant in azimuthal anisotropy, and multicomponent seismic, for oil and gas exploration and development. Prior to consulting, she worked for BP, Amoco, and Texaco. Her Ph.D. in Geophysics is from Stanford University, where she studied under Prof. Jon Claerbout and Prof. George Thompson. In 2015, the SEG awarded her the Fessenden Award, for her 35 year career of translating the anisotropic behavior of seismic waves into practical applications that allow stress fields, fracture systems, and geomechanical properties to be characterized in targeted rock systems.
