This study illustrates a field application of a robust and reliable approach for assessing geomechanical parameters during drilling operation or as a post-mortem analysis. The methodology leverages surface logging drilling data (such as Rate of Penetration, Rotation Per Minute, Weight on Bit, Torque, Standpipe Pressure, and Flow rates) along with well log data (including Sonic log, Bulk Density log, and Gamma Ray log) as input of the methodology. This model is grounded on the integration of various data processing techniques and machine learning algorithms (encompassing Multiple Linear Regression, Support Vector Regression, Random Forest, Artificial Neural Network, and XGBoost), ensuring a comprehensive and accurate evaluation of geomechanical parameters in the area under evaluation.
The methodology is applied to a dataset of six wells drilled in the same geological units of an area located towards the eastern limit of the Neuquén Basin, north of the ‘Dorsal de Huincul’ (Gonzalez et al. 2016). The results associated with Young’s Modulus, Density, and UCS, here presented, provide evidence of its successful use in a challenging geological context such as the unconventional plays in Argentina.
