Fractures and Diagenesis, their Occurrence and Impact on Paleocene Dolomite Reservoir

in Carbonate reservoirs. These two natural phenomena can be acting as positive reservoir contributors, in terms of reservoir efficiency and production, and also can be acting as negative contributors. In the last years, the carbonate reservoir remains the most challengeable reservoirs in exploration and developments where their reserves estimation and production amounts remains undefined precisely. This is directly related to the nature of the Carbonate reservoirs depositional processes formation syn-depositional and post-depositional. Carbonate reservoirs account for 40% of today’s hydrocarbon production, and because of several giant fields in the Middle East they are expected to dominate production through the next century. In Libya, carbonate reservoirs are mainly concentrated in Sirte Basin and offshore where the first exploration in 50’s where in reef carbonate reservoir. Therefore, understanding carbonate reservoirs and producing them efficiently have become industry priorities and are likely to remain so.
