After sidetracking, the well was drilled to a depth of approximately 5,500 feet TVD and seven-inch casing was set just above the interval where high mud gas and overpressure was encountered in the previous well bore.

Previously, the Jatayu-1 well was drilled to a depth of approximately 5,920 feet true vertical depth (TVD). Strong overpressure estimated at approximately 600 pounds per square inch and extremely high mud gas readings of up to 80 per cent were observed between approximately 5,530 and 5,920 feet TVD with difficulty maintaining adequate mud weight from 5,631 feet due to the influx of gas.
