The ripple bands occurred in a confined and patchworked region...

... PSV reduces (from 40% for the G3 eastern North Island greywacke to 24% for the G1 Whangarei greywacke). There is very little difference in the final level of ESR as measured by the DFTester for the five natural aggregate samples (range from 0.39 to 0.46μ, except for the less lithified and more...

The rig was scheduled to start on an extended drilling campaign for various companies early in 1975. Meanwhile, semidetailed to detailed offshore seismic...

... will retain title to the condensate and pump it through a 33-mi, 6-in. pipeline to New Plymouth. From New Plymouth the condensate will be shipped to the Whangarei refinery north of Auckland. The use of the Kapuni gas and condensate will save New Zealand more than $2.8 million a year in foreign exchange...

...) to the Whangarei refinery. Production at year end was approximately 15 MMCFGD and 1,400 b/d of condensate. This amount should increase, according to the original schedule, to about 40 MMCFGD and 3,500 b/d of condensate. Reserves at Kapuni are calculated at 400 Bcf of gas and 26 million bbl of condensate...
