Understanding Fractured Plays

Fractures play a big role in development and production. They affect the quality of subsurface images, distorting seismic signals in the overburden. They control production, sometimes impeding it and other times enhancing it. Our reservoir packages use the latest seismic techniques and geoscience software to detect and harness fracture-induced anisotropy. Building a model from this and other field data yields a detailed view of fractured reservoir characteristics. Armed with this understanding of fractures and resource-in-place, you can determine the best development plan for the play.

Understanding Fractured Plays

Fractured Reservoir Characterization

Large scale fracturing and faulting has an important impact on the structure and connectivity of the reservoir. New imaging algorithms and dedicated interpretation tools like FaultFractureSpark provide enhanced and rapid fault interpretation.

Smaller fractures visible only at the log and core scale have an equally important role to play in naturally-fractured reservoirs. Anisotropy observed in fractured formations distorts the seismic image. Azimuthal anisotropy analysis of wide- and full-azimuth surveys and analysis of multicomponent seismic provide the parameters required to focus images using orthorhombic velocity models and migration algorithms.

This seismic anisotropy provides information on the spatial distribution of fracture intensity and orientation which can be unlocked with a suite of GeoSoftware analysis tools including ProAZ and GeoConsulting Seismic Reservoir Characterization workflows for azimuthal inversion.

Calibration with core and image log data provides the basis for quantitative interpretation of fractured plays allowing you to target or avoid fracture swarms with development wells. For reservoir model building, the Robertson Analogues fractures knowledgebase provides unique context.
