One of stratigraphic traps which formed associated with subsurface diagenesis is porous carbonate facies. This trap group could evolve locally and regionally. The most common type is formed from the process dolomitisation where magnesium carbonate limestones deposited with less volume than the calcium carbonate replaced by a solution, resulting in porous and permeable rock.

In addition, the stratigraphic trap that can be influenced by subsurface diagenesis is a reef or bioherm (Landes, 1946). The main reason of oil production from some reef which rest on high porosity and high permeability reservoir rock. This porosity can be formed early or can be induced. Porosity early formed between the presence of abandoned spaces where the organisms life and the empty cavity between the outer wall shells on the set various organisms. While the induced porosity is generated from washing mass coral reefs by the circulation of water when approaching the surface, solution which exceeds precipitation during dolomitisation and can also be from reef fracture because the movement of the earth.

Diagenesis below the surface also has a relationship with the migration. When migration occurs early and precedes episodes of tilting or folding it takes prudence on the possible diagenesis trap (Wilson, H.H., 1975, 1977). Migration earlier indicated by some diagenesis carbonate sequences which suffered beforehand as cementation.
