PA Wellington The Tariki North 1A well, in eastern Taranaki, is to be abandoned as a dry hole, Petrocop said yesterday. During the last week the well was deepened from 2846 metres to 3208 metres.

Hydrocarbon shows were recorded over the interval 2900 metres to 3208 metres. The interval 2904 metres to 3023 metres was cored, and the well was electrically logged at 3208 metres, Petrocorp said. Evaluation of the logs showed the reservoir to be water-saturated and it was decided to plug and

abandon the well as a dry hole.
