Wellbore integrity analysis for wellpath optimization and drilling risks reduction: the Vaca Muerta Formation in Neuquén Basin
The Vaca Muerta Formation of the Neuquén Basin is an emerging shale play with extensive lateral extent and thickness up to 300m with significant anisotropy and heterogeneity throughout the basin. Stress analysis obtained using drilling induced tensile fractures and breakouts indicate a steadily orientated stress tensor and principal stress magnitudes consistent with the normal faulting stress regime. Analysis of wellbore integrity and limited number of wells drilled imply that horizontal wells drilled in the north-south direction in the Vaca Muerta Formation are the most productive. An integrated ...
