Diagenetic relationships and reservoir quality implications in Brookian Clastic sequences, National Petroleum Reserve, Alaska

Petrologic and petrophysical investigations of Brookian sandstones and siltstones from wells in the National Petroleum Reserve in Alaska revealed new information about the diagenetic development of these rocks. Several kinds of labile materials are present, and secondary dissolution porosity has been developed to various degrees. Mineralogic, geochemical, and textural characteristics indicate the potential for development of appreciable porosity of this type in equivalent horizons and/or similar materials within northern Alaska.
