WAITARIA 2 EXPLORATION WELL,
PEP 38335, EAST COAST NEW ZEALAND,
COMING OUT OF HOLE FOR A BIT CHANGE AT 1103 METRES.
Pancontinental Oil & Gas NL is pleased to announce that at 9:00 am (NZST) 8 February 2001, the Waitaria 2 exploration well was coming out of the hole for a bit change at a depth of 1103 metres in a sequence of Late to Mid Miocene age claystones and tight siltstones.
334mm casing was run and cemented to a depth of 557 metres.
While drilling down to 1103 meters, background gas levels have ranged up to 0.2%, with encouraging chromatograph readings up to C4(butane). Mud weights have been increased to 14.5 ppg. These gas and chromatograph readings are consistent with those encountered in the Waitaria 1 well with comparable mud weights.
The well will be drilled to a depth of 1372 metres where 247mm casing will be run and cemented. The target Tunanui sandstone is anticipated below this depth.
The Waitaria 2 well will be drilled to a proposed total depth of 1829 metres, and is located next to the 1997 Waitaria 1 well. Waitaria 1 failed to reach the objective Mid-Miocene Tunanui sandstone due to mechanical problems associated with abnormal pressure. These problems are being addressed in the Waitaria 2 well with more robust casing and mud programs.
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.
The operator has estimated that the potential recoverable reserves of the Waitaria prospect are 88 million barrels oil or 360 billion cubic feet gas.
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.
