Common pore types in Jurassic carbonate reservoirs in the Gulf Coast include lime grainstones of the Smackover Formation in southern Arkansas and northern Louisiana with interparticle and grain-moldic pore systems, dolomitized pelletal packstones, and grainstones from the Jay field in Alabama and Florida with mainly pelmoldic porosities, and Haynesville oolitic grainstones from east Texas with partial grain-moldic pores. Reservoir quality in all these examples is a function of both primary depositional and secondary diagenetic processes.
