  • Abstract

    Burrow-associated diagenetic alteration and eventual reservoir quality parameters such as porosity and permeability may be altered due to reorganization of the sediment fabric associated with animal burrowing, or result from heterogeneous cement distribution influenced by the bioturbate texture.
    Petrographic analysis has significant application in recognizing burrow-associated porosity characteristics in marine sandstones. Petrographic analysis can provide mineral identification due to diagenetic chemical alterations and textural evidence regarding cementation history that can lead to more accurate hydrocarbon target interpretations.
    Overlooking burrow structures may lead to misinterpretations of permeability streaks in hydrocarbon reservoirs. This may be extremely important for reservoirs where slight permeability variations have an effect on hydrocarbon reserve calculations.
    Understanding biogeochemical reactions and burrow-associated diagenesis that ultimately control reservoir quality is necessary if production from ancient bioturbated marine sandstone reservoirs is to be optimized.
