  • This paper examines one of the key factors that give New Zealand coals their capacity to generate and expel oil. Globally, coals have traditionally been regarded by the major exploration companies as gas-prone and this has been a major impediment to attracting sufficient exploration investment to New Zealand, because coaly rocks are the primary source rock type in most New Zealand basins. The motivation for this paper was to demonstrate that the total oil potential and oil expulsion efficiency of New Zealand coals have been considerably enhanced by marine influences within the coal-forming depositional environment.

Our staff on the radio

Rob Funnell, head of the Petroleum Geoscience department, was interviewed on Newstalk ZB about the implications for the petroleum industry after the Anadarko Romney-1 well was plugged and abandoned. Listen here.

Newly Added to Petroleum Basin Explorer (PBE)

  • East Coast Basin Source Rock Properties Database - This new database provides Rock-Eval pyrolysis and vitrinite reflectance data for 1115 well and outcrop samples of Cretaceous to Neogene rocks from the East Coast Basin of New Zealand. It represents an update of the earlier database of Hollis & Manzano-Kareah (2005). Various sample stratigraphic assignments have been updated and additional data have been included from public domain reports, university theses, and unpublished GNS Science data sets.
  • Downloadable Science Reports - A range of GNS Science Reports relevant to petroleum exploration are now available for free.
  • Regulatory Map - This new map shows This map shows government, iwi, and environmental data relevant to petroleum exploration. The DoC layers are very large data-sets, so be patient as they load.

GNS Science at the Advantage 2013 New Zealand Petroleum Conference

Geological Transect Across the Wairoa Area

Insights into elements of the East Coast petroleum system

GNS Data Series 11a product compiles industry and research data on the Wairoa area of northern Hawke's Bay and summarises interpretations and conclusions relating mainly to the hydrocarbon reservoir potential of the Middle Miocene Tunanui Formation. Aspects addressed include clastic and fractured reservoir quality, seal quality, seismic interpretation and facies, faults and fault seal and the present stress regime.

Updated Paleogeographic maps of the Taranaki Basin and surrounds. 

As part of the facies characterisation objective of the 4D Taranaki (4DT) Project, a regional reassessment of the paleogeographic evolution of the Taranaki Basin and surrounding areas has produced a set of 31 maps spanning the Late Cretaceous to present day, which expand on those from previous studies and incorporates significant new data. These maps capture the most important aspects of the tectonic and sedimentary evolution of the Taranaki Basin, and form the basis for ongoing detailed paleofacies mapping and basin modelling studies.

GNS Data Series 5a

The product is available in two GIS geo-databases:

Results from high-resolution seismic surveys collected over several decades at the University of Otago has recently been published in the NZ Journal of Geology and Geophysics. One of the authors Matt Hill from GNS Science, was instrumental in writing the code that digitised the original analogue data collected by the single-channel boomer seismic surveys, and converting these into SEG-Y format. This enabled digital processing of the data such as deconvolution, spatial filtering and migration, as well as more effective archiving of the data.

Greg Browne wins Harold Wellman Prize.

Greg Browne won the Harold Wellman Prize at the annual New Zealand Geoscience Society Conference held in Auckland in December 2010. Greg was the first to discover dinosaur footprints from New Zealand, and published these findings in the New Zealand Journal of Geology and Geophysics in 2009. LINK . The discovery is also the first record of dinosaur remains in the South Island. The find was made in tidal deposits of the Late Cretaceous North Cape Formation in northwest Nelson, and comprise a series of localities where a range of footprint sizes and morphologies are present. They were all formed by sauropods, large herbivorous dinosaurs with rather club-like feet. Full abstract.

Paper on Late Cretaceous shallow marine sandstones published.

A recent paper published in the journal Marine and Petroleum Geology LINK reviews the geology of Late Cretaceous rocks of Taranaki Basin. Authors Karen Higgs, Malcolm Arnot, Greg Browne, and Liz Kennedy have integrated outcrop and subcrop data in this review paper, which emphasises the characteristics of these potentially significant reservoir facies. GNS workers in related papers, have described much already about these sediments with respect to their source rock potential. In this paper the sedimentology of Rakopi and North Cape formation rocks are described, integrating wireline logs and biostratigraphy, petrographic data, and reservoir quality, with revised paleogeographies for the entire offshore portion of the basin (including 17 wells from Ariki-1 in the north to Cook-1 in the south). Full abstract.
