Applied Geomechanics for Conventional & Unconventional Reservoirs
This course covers a broad range of necessary knowledge of geomechanics for conventional and unconventional reservoirs, starting from the fundamental of rock mechanics and how to obtain essential data from experiments, understanding the origin of pore pressure and methods to measure and estimate it, describing the principal stress state and having the knowledge to estimate and validate their orientations and magnitudes. The course then proceeds with applying those data to geomechanically modelling, starting with structural geomodelling concept to its geomechanics application.

A researcher in rock mechanics and geomechanics within the Geodynamics and Sedimentology Research Group at Institut Teknologi Bandung (ITB), with research focusing on characterizing the mechanical properties of shale formations in Indonesia related to hydraulic fracturing applications. He holds a B.S. and M.S. in Geological Engineering from ITB, with academic work covering regional geological cross-sections and fracture characterization in carbonate rocks. He later earned a Ph.D. from the University of Wisconsin–Madison (USA) with a dissertation on the geomechanical study of Indonesian organic-rich shale rocks, followed by post-doctoral research on rock mechanical testing of Indonesian shale.
With around two decades of experience in the geology and energy industry, he has worked with both operator and service companies in the oil and gas sector, including roles involving geological analysis, subsurface evaluation, and geomechanical applications. He also brings extensive experience in consulting and professional training for various reservoir types, including siliciclastic, carbonate, volcaniclastic, fractured, and unconventional reservoirs. His expertise includes communicating complex geological and engineering concepts to diverse audiences, from early-career professionals to senior specialists. His research interests span petroleum, geothermal, mining, civil, and environmental engineering applications, particularly in rock mechanics, geomechanics, time-dependent deformation, structural geology and tectonics, petrophysics, and earth modeling.
