Interpretation for unconventional resources introduces a broad range of issues and objectives that are markedly different from those encountered when interpreting for conventional plays. There are of course many commonalities. Structural interpretation is still a strong driver, particularly to assist in geosteering horizontal wells with long extended reach. Structural attributes can also aid the analysis of the stress field and can inform the interpretation of microseismic data.

Beyond this, however, there’s a greater prize to be pursued: characterization of the unconventional reservoir with a goal of optimizing field development. Given the size of reserves that are involved and the magnitude...
