High Resolution Timelapse Imaging – Salt Creek Case Study

We present a methodology for high resolution timelapse monitoring over an onshore oilfield and demonstrate the method with a case study from the Salt Creek Field, Wyoming, USA. Key aspects of the method are: 1. High reproducibility in acquisition through the use of permanently emplaced geophones, 2. Consistent processing of all surveys, with an amplitude-friendly processing flow, and 3. Detailed characterization over time by recording multiple monitor surveys at time intervals of 10 – 14 weeks. This case study vividly demonstrates the ability to monitor CO2 movement in an onshore field with high spatial and temporal resolution and illustrates the flow patterns that can be identified with this technique.
