Integrating Pyrolysis and Geochemical Techniques for Unconventional Reservoir Assessment and Development Optimization

Summary The analysis and interpretation of the Makhul Formation through deviated wells, core acquisition, and production tests have provided a more detailed understanding, challenging the initial perception of the reservoir as too tight for exploration. This comprehensive study has accurately estimated the Total Organic Carbon (TOC) content in extractable hydrocarbon zones, shaping future development strategies for the Makhul Formation as an unconventional reservoir. The investigation focused on the interval from 11495 ft. to 12620 ft., revealing distinct sub-layers within the Makhul Formation based on inorganic geochemistry data (XRF & XRD) and organic geochemical analysis (Pyrolysis). The Upper Makhul layer comprises mainly calcite and clay, with decreasing Kerogen proxies downward. The Middle Makhul layer shows evolving dolomite and clay content, while the Lower Makhul layer exhibits increased dolomite and Paleredox proxies, indicating a different Kerogen presence. The HAWK PAM analysis of multiple intervals provides valuable insights into the organic composition and geological characteristics of the Makhul Formation. The study provides novel insights by integrating advanced techniques such as HAWK pyrolysis and XRF/XRD geochemical analysis to characterize the Makhul Formation.
