WAITARIA 2 EXPLORATION WELL,
PEP 38335, EAST COAST NEW ZEALAND, PREPARING TO RUN A PRODUCTION TEST OVER THE INTERVAL 1402 TO 1412 METRES.
Pancontinental Oil & Gas NL announces that following a review of electric logs run over the open hole interval of 1351 to 2134 metres, preparations to run a cased hole test over the interval 1402 to 1412 metres are now in progress.
The petrophysical interpretation of the electric logs indicated the presence of two zones, over the gross intervals of 1402 to 1412 metres and 1887 to 1893 metres, that indicated the possible presence of hydrocarbons in sandstones with improved reservoir characteristics. The operator recommended that these zones warrant further evaluation and has elected to proceed with the testing of the 1402 to 1412 metre interval.
As reported previously, thick sandstone units with interpreted good reservoir characteristics, known to be present in the Tunanui Formation from coastal and inland outcrop exposures, have yet to be penetrated in this well. The deepening of the well below the original total depth of 1829 metres was aimed at achieving this objective. However, it must be noted that given the distances from the well to those outcrops, estimates of the depth at which those thick sandstone units could be intersected are not precise. Biostratigraphic (fossil) information from the strata at 2134 metres indicate an age that is immediately above that of the strata containing the thick sandstone units.
Deepening of the well will be considered once the results of the production test are known.
Pancontinental Oil and Gas NL announced previously that it had reached agreement with Westech Energy New Zealand to earn a 7.5% equity in PEP 38335, East Coast Basin of the North Island of New Zealand, by contributing 10.0% of the US $1.327 million drilling costs of the Waitaria 2 well. Pancontinental will only contribute 7.5% to additional drilling, completion and testing costs. This agreement is still subject to final Government approval.
The Waitaria prospect has been delineated by a close grid of modern 2D seismic data. The prospect has been mapped by the operator to have 4 way dip closure over an area of 6 square kilometres and vertical closure of 700 metres at a level immediately above the primary Mid-Miocene age Tunanui sandstone target reservoir.
PEP 38335 covers an area of 409 square kilometres and incorporates the regional city of Gisborne. Approximately 50 kilometres to the south-west, in the Westech operated PEP 38329 permit, are the late 1998 Kauhauroa and Awatare gas discoveries, adjacent to the town of Wairoa. The Kauhauroa and Awatare gas discoveries are in Miocene reservoirs and recorded test gas flows of up to 11.5 million cubic feet per day.
Participating interests in PEP 38335 (after earning) are :-
| Pancontinental Oil and Gas NL | 7.5% |
| Westech Energy New Zealand | 27.5% (Operator) |
| Orion Exploration Ltd | 27.5% |
| Indo-Pacific Energy (NZ) Ltd | 25.0% |
| Sun Resources NL | 7.5% |
| Everest Energy Inc | 5.0% |
