Generally calcite cement filled pore cavities at the contact of oil / water, trapping oil (sealing oil) between reservoir and reservoir formation impermeable here in after the movement of fluid. When cementation occurs extensively contact in the oil / water followed by a period of tilting or folding it no loss of oil from the reservoir and there is no transfer of oil to structural highs. When the trap diagenesa formed between rock sequences, exploration drilling on the structural highs will not succeed. To determine the location of potential diagenetic trap required sequence are not tilted or not bent by using information from seismic so that can be found trap earlier position that is covered by cementation at the contact of oil / water.
