Abstract
Wellbore stability analysis has been carried out for wells to be drilled in a highly tectonic area, involving overpressured sands,<br>laminated shales and steeply inclined beds, in Eastern India. Data acquired on wells abandoned in the past with 52 to 73%<br>NPT, have been utilized to generate static mechanical properties and in-situ stress information.
