The interwell region is a frontier, poorly understood and lacking information to optimally apply enhanced recovery techniques. 3D surface seismic lacks the resolution to characterize structure or monitor property changes. The barrier to enhanced recovery is an adequate description of heterogeneities between wells. Crosswell seismic provides seismic images between wells, at the resolution of well logs, to fill-in the information void that occurs in the interwell frontier. The talk will describe crosswell seismic data and cover the application and operation of crosswell seismic. Topics include:

• Concept and Benefits of Log-Scale Seismic Imaging
• Technology Convergence to Meet Real-World Problems
• Applications
• Reservoir Monitoring: CO₂, steam, water
• Reservoir Characterization/Structural Imaging at Reservoir Scale
• Strategic Infill Wells
• Targeted Horizontal Wells
• Crosswell Project Elements
• Survey Planning
• Information/Well/Field Requirements
• Survey Plans: coverage, duration, cost
• Data Acquisition
• Tools
• Operations
• Data Processing
• Techniques
• QC
• Deliverables/Schedule/Cost
• Integration/Interpretation
