CoViz real-time data monitors surface deformation

Dynamic Graphics’ flagship used to monitor heavy oil operations in San Joaquin Valley.

A new AAPG paper shows how Dynamic Graphics’ CoViz was used to visualize and investigate a large, heterogeneous data set collected to monitor surface deformation in the San Joaquin Valley, California. Here, oil field operations have significant financial, operational, and safety implications. Heavy oil production, water and steam injection from and into shallow reservoirs can create significant surface deformation.

SkyGeo’s satellite-based interferometric synthetic aperture radar (InSar) has proved a powerful tool for monitoring such deformation throughout time. But the true value of InSAR data is revealed when integrated with time-based production and injection data along with cultural data, geologic models, well trajectories, microseismic and tilt meter data.

The authors insist on the importance of the ‘temporal component’ and present a case history spanning some twenty years of production and surface deformation. CoViz enabled long-term subsidence patterns to be related to fluid production and local pockets of uplift to over-injection. CoViz was originally created for BP as a vendor-independent browser for seismic, well and reservoir simulation data (OITJ 2006/12). More from Dynamic Graphics.
