Analysis of the Petroleum Generation Potential of the Previous HitNealNext Hit (Floyd) Shale in the Black Warrior Basin using Kinetic and Basin Modeling

An analysis of the Previous HitNealNext Hit (Floyd) Shale in the Black Warrior Basin will be conducted in order to determine its potential as an unconventional reservoir for natural gas and oil. Focused ion beam milling coupled with scanning electron microscopy will be used to investigate the source of porosity within the shale at four different kerogen maturity levels. Once the source of porosity has been established, a kinetic model of porosity development, along with basin modeling will be used to estimate the type and volume of hydrocarbons that have been generated. A kinetic model based on total organic carbon (TOC), kerogen type and the hydrogen index (HI) will be used to estimate the porosity that has been induced by kerogen decomposition to oil and gas. This porosity will be coupled with basin modeling to determine the type and volume of hydrocarbons that have been generated. The mineralogy of the Previous HitNealNext Hit (Floyd) Shale will be analyzed in order to explore brittleness, a primary factor governing hydraulic fracturing success. If sufficient hydrocarbons have been generated and stored within the shale and the mineralogy is suitable for successful hydraulic fracturing, production of petroleum from the Previous HitNealTop (Floyd) Shale will help produce a source of revenue and jobs for the state of Alabama, while helping achieve the U.S. goal of energy independence.
