Much work has already been undertaken by various operators throughout the industry to explore frontier areas and drill into ever-deeper geological horizons. High pressures and temperatures in the range of 15,000 psi and 450-F need to be handled to safely drill and produce these targeted reservoirs.

This paper illustrates the experience of an E&P operator in the exploration process of a deep Ultra HPHT field offshore east India.
