1D Geomechanical Model For Wellbore Stability in Z Field, Y Well Sanga Sanga Working Area, Kutai Basin

This research is about 1D geomechanical model for wellbore stability in Z Field, Y Well Sanga Working Area, Kutai Basin where wells have been drilled. The Purpose of this Research to analyze the well starting from knowing stress regime that occurs, predicting occurrence failure, and determining safe mud weight window next drilling. method use a numerical modelling using log data drilling has obtained then managed Techlog Software. result show magnitude mechanical properties rock obtained, general occurs Field formation normal even though strike slip reverse are inserted at certain depth, based on prediction results failure wide breakout, which lithology with sandstone, finaly can be estimated properly, so it used further value formation,
