Abstract (Summary)

Advanced shale distribution analysis was conducted on ten triple combo-logs throughout seven separate deep-water marine reservoirs of varying environments of deposition in Lobster Field of Ewing Bank 873. Conventional and sidewall core photos and data, Laser Particle Sieve Analysis (LPSA), thin section photographs and electron microscopy were integrated to determine shale type within these reservoirs. By identifying spatial distribution of varying shale type, an enhanced reservoir model may be constructed to aid in reservoir development.

Typical shale analysis assumes shale is distributed in only one way in a given interval, while this study adopts the idea that there are likely multiple types of shale which will variably affect reservoir performance. By utilizing high-resolution conventional slabbed core and thin section photographs, intervals which exhibit multiple shale types may be flagged and analyzed. By doing this, a more accurate reservoir model will be constructed which will aid in the evaluation and allow for a better understanding of these mature reservoirs.
