Announcing: Advantage NZ: 2014 Geotechnical Petroleum Forum
New Zealand Petroleum & Minerals, in partnership with GNS Science, is pleased to announce the launch of Advantage NZ: 2014 Geotechnical Petroleum Forum. This forum will provide a venue for interaction and sharing of information between oil and gas professionals in Government and industry.
This new technical forum will focus on subsurface geological, geophysical, geochemical and petrophysical elements of petroleum prospectivity in New Zealand. It will feature the release of new technical data and results of the latest research in the sector aimed at supporting the anticipated launch of Block Offer 2014.
Visit the Advantage NZ website for more information.
GNS Science Pre- and Post Conference Field Trips
We are running a range of pre- and post-conference field trips.
This four day pre-conference field trip will examine a wide variety of source, reservoir and seal lithologies exposed in the northern South Island, outcrop analogues for similar units in the offshore basins. The trip will include both classic and not so often visited localities that are representative of Late Cretaceous to Neogene sedimentary units of the Great South, Canterbury and Pegasus basins of the eastern South Island.
This one day pre-conference trip to southeastern Wairarapa will take in several stops encompassing a range of source and reservoir rocks near Castlepoint. This trip will have an appeal to those interested in eastern North Island and Pegasus Basin geology. Stops will include Paleocene-aged source rock units, Miocene turbidites, and Pliocene carbonates, as well as spectacular coastal scenery.
This post-conference trip will examine some of the aspects of the active Wellington Fault in and around the Wellington urban area. A considerable amount of investigation has been undertaken on the fault, principally as New Zealand’s capital city and associated Lower and Upper Hutt cities lie along its length. Frequent earthquakes, most recently emanating from the adjacent offshore Cook Strait and northern Marlborough regions are features of the Wellington area. Town planning and human activities live with these geological issues, and this trip will stop at several classic locations to view fault related features.

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.
The product is available in two GIS geo-databases:
Strogen, D.P. (compiler), 2011. GIS project: Updated paleogeographic maps for the Taranaki Basin and surrounds - Cretaceous-Paleogene: early rift to maximum flooding. GNS Science data series, 5a.
Strogen, D.P. (compiler), 2011. GIS project: Updated paleogeographic maps for the Taranaki Basin and surrounds - Neogene: active margin tectonics. GNS Science data series, 5b.
Both of the above are combined on one CD priced at $30 plus postage.

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.
