(Rs. in Crore)
Expenditure	Depreciation	Total
34.57	3.95	38.52

(d) & (e) Yes, Madam. Drilling could not be carried out due to drilling complications in the well after depth of 3914 meters. After making several attempts to retrieve the fish and also sidetrack the well, drilling was terminated.

As per the prospectivity analysis, four zones were expected in the Upper Bhubhan and Bokabil formations. However, after drilling of well these zones were found to be having very high water saturation and considered as water bearing. Hence, the well CPAA was abandoned.

(f) Since no lead or discovery could be established in the area, Petroleum Exploration License (PEL) for sixth & seventh year extension has not been granted and PEL was surrendered on 12.05.2009.
