The purpose of this district layers (n21) clastic reservoir rocks are mainly fine-grained sandstone and siltstone, in which the reservoir properties of the main effects of diagenesis types of compaction and cementation.

The purpose of Layer 21 (N ) rock debris from the floor to break down rock of sandstone and siltstone, mainly to the level of a major influence of money in a rock type role for real-time role and pressure bonding by gluing.

The home court goal stratigraphic interval (N21) clastic rock reservoir lithological character take the novaculite and the siltstone primarily, in which has the major effect diagenesis type to the reservoir nature as the compaction function and the cementation.

The interval of interest (N21) lithology of clastic rock reservoir sand rocks and mainly Siltstone, which have a major influence on reservoir physical properties of rock types for compaction and cementation.
