Recent advances in 3D geological interpretation techniques allow for more accurate, interactive multi-disciplinary interpretation of stratigraphic frameworks in unconventional reservoirs. The integration of seismic data with well logs, core descriptions, hydraulic frac, and production data, combined with stratalslicing techniques leads to better insight into an unconventional reservoir's prospect potential.
In these field examples, the described techniques are shown to be instrumental in identifying productive reservoir intervals, by enabling interpreters to more accurately define the structural and stratigraphic framework in the pre- and post-drill stages as well as during the drilling phase.
Successful geological interpretation of unconventional reservoirs depends on the integration of data management, visualization, stratigraphic analysis, and interpretation. Reservoir flow unit connectivity and continuity can be deduced from the 3D geological interpretation results and corroborated with production data.
