Each reservoir element will be described in terms of different data sets and scales of resolution Overview remarks and observations Regional-scale data sets: sea-floor images, seismic reflection data: vertical and horizontal views wireline log expression, seismic-to-well ties Development-scale data sets: “sub-seismic scale” Outcrops: address key reservoir issues: lateral continuity, vertical connectivity; textural, compositional and structural characteristics Borehole images and cores Producing fields: 1-2 examples with thorough documentation in literature, additional examples included in the text (before publication of GSL Memoir 24)
