-//Chart showing closely-spaced biostratigraphic events to warn of the impending arrival of the drill string in the target zone just above the (underpressured) reservoir. When the markers for higher zones like TM7 to TM4 were observed in the samples, the ROP could be controlled to allow closely-spaced samples to be taken to look for markers TM3 d, c, b, a and ax. When markers for TM2 were seen drilling could be stopped quickly without risk of penetrating the reservoir (TM1).//

-The technique was used on the subsequent 12 production wells drilled with no “lost holes” thereby estimating a saving of $24 million by not losing any redrilling time or drilling equipment.

The estimated life span of the field was also increased because of the increased confidence in future safe drilling.
