Current master thesis deals with petrophysical and geomechanical analysis of the Tensleep formation, Teapot Dome field in Natrona County, Wyoming, United States of America. The main aspect of the analysis is the selection of a suitable location (well) to carry out the injection of CO2 as the last and integral part of the carbon capture and sequestration technology. This is done through a careful analysis of a list of factors that affect the integrity of the caprock, which during the thesis was considered of critical importance. Dominant part of the analysis is performed with two key Schlumberger softwares: Techlog Wellbore Software Platform, which integrates all wellbore-centric data types into multidisciplinary workflows and Petrel E&P Software Platform, which allows to perform well correlations, interpret seismic data, build reservoir models, calculate volumes and others. The well selection process is divided into three key parts: (i) ductility-brittleness maps are created for the caprock zone according to the cross-plots of Young's modulus-Bulk modulus and (ii) calculation of HCPV amounts for the reservoir and (iii) juxtaposing these techniques via six types of constraints that yield a number of possible scenarios, from which the most optimal well can be selected.
