AWE Limited disclosed that as at 06:00 hours (6.00am NZDT) Tuesday, the Pateke-4H development well sidetrack has been drilled to a measured depth of 13,395 feet (4,083 meters) in petroleum mining permit (PMP) 38158 off New Zealand, landing at an angle of 90 degrees and having penetrated the hydrocarbon bearing F10 reservoir sand. Installation of the 9.625 inch casing is currently in progress, following which the well will be drilled horizontally through the reservoir to a planned measured depth of 17,588 feet (5,361 meters).
The Kapuni F10 sandstone objective has already been intersected on prognosis with oil shows and real time logging measurements indicating the likely presence of an oil bearing reservoir. The commercial significance of the oil shows will not be clear until the horizontal drilling is completed and the reservoir size and quality is fully assessed.
The Pateke-4H development well is in PMP 38158 and AWE is the Operator. Located in the offshore Taranaki Basin, New Zealand, PMP 38158 contains the Tui, Amokura and Pateke fields and has been producing since 2007.
Pateke-4H is targeting a mapped northern extension of the currently producing Pateke field. The well is being drilled in water depth of approximately 406 feet (124 meters) with a planned total measured depth of 17,588 feet (5,361 meters), including a 4,173 foot (1,272 meter) horizontal section. If successful, the well will be completed for subsequent tie-back to the Tui FPSO (Umuroa) for production in 2015.
