A REVIEW OF EOCENE NUMMULITE ACCUMULATIONS: STRUCTURE, FORMATION AND RESERVOIR POTENTIAL

摘要

Eocene nummulite accumulations, also referred to as nummulite "banks", form important hydrocarbon reservoirs in Tunisia and Libya and may constitute exploration targets in other parts of North Afirca, the Mediterranean and the Middle East. Porosities commonly average 10-20% and permeabilities 10-50md.
