Tullow Oil has concluded its current drilling campaign in India with completion of the latest well in Block CB-ON/1. The F1 well failed to encounter hydrocarbons and has been plugged and abandoned.
Drilling operations at F1 commenced on September 30 and the well reached a total depth of 2,164 m on October 18. No significant porous zones were encountered in the primary Olpad objective and sands in the secondary Kalol objective were poorly developed. No evidence of hydrocarbons were encountered in either zone during drilling or logging operations.
F1 was the third and final well in the 2008 drilling campaign. The CB-ON/1 partners have agreed to release the rig while they reassess the remaining prospectivity of the block using data from the recently drilled wells.
Aidan Heavey, Chief Executive, said, "The recent drilling campaign has completed our agreed license obligations on CB-ON/1 but unfortunately results did not meet with our expectations for the area. The information and data gained from the three wells will now be fed into our regional model enabling us to focus on the forward exploration program for the acreage."
