Executive summary

Higher well productivity can be associated with porosity and permeability preservation, resulting from early trap formations due to the following issues that may be implied to various types of oil and gas fields.

– Can level of diagenetic alteration be reduced due to restricted fluid flow? Fractured zones and sand bodies may form early traps, where brines later be displaced by oil as surrounding/nearby source rock began to generate Hydrocarbons. This brines migration may be related to the alteration, which destroyed major part of porosity/permeability. Areas of early presence of oil would be less significantly impacted.

– Under-compaction, in low N/G systems, should provide more opportunity for sealing individual, isolated sands. This type of formation may also imply that brines would not be able to migrate out the sands giving rise of overpressure.

– How to use near miss well’s reservoir quality to assess where one might move to find discoveries in better brines which can be displaced by oil in fractured zones and sand bodies as surrounding source rock began to generate hydrocarbons. This brines migration may be related to the alteration, which destroyed the major part of porosity and permeability. Areas of early presence of oil would be significantly less impacted by the process.
