Calibration of a poroelastic rock physics model from well logs and cuttings: a case study from Inoceramus shale, Austral basin, Argentina

The evaluation of elastic and geomechanic coefficients in reservoir rocks at well scale is needed for their characterization and also for planning drilling and production strategies. This is very important in unconventional organic rich shale reservoirs such as Inoceramus formation, the main source...
