Avalon

avalon

Located in one of North America’s most prolific basins, the newly acquired 282 square miles high-end 3D seismic survey offers 400-fold broadband data. Setting a new standard, Avalon allows better imaging to address the noise and statics challenges in the area.

Targeting the Bone Springs, Wolfcamp and Cline formations, this complete solution ties the geophysical data to the geology, enabling enhanced sweet spot detection and improved hazard avoidance for optimal well placement.

The project uses a multi-disciplinary approach comprising advanced imaging, reservoir characterization and microseismic monitoring.
