Core Workshops for Graduate Students
For the past two years, the PBR programme has been supporting a 1-day training workshop for graduate students, teaching them how to work with and describe industry core. Our first workshop was held in November 2014 in New Plymouth, and we repeated the workshop in November 2015. Both events have been a part of the national Geoscience Society of NZ (GSNZ) conference. We were fortunate to use the CoreLab facility in New Plymouth and the NZ Petroleum & Minerals core store in Featherston on these two occasions, and to have sponsorship from OMV and PEPANZ. Both workshops have been run by Greg Browne and Mark Lawrence. These workshops form part of the activities of the Sedimentology Special Interest Group (SSIG) within GSNZ, a group set up to promote communication and support among sedimentologists and provide a forum for discussion of aspects of sedimentology, stratigraphy and sedimentary geology in New Zealand. If anyone wishes to become involved with this group, please email the Convenor Mark Lawrence.
The core workshop was primarily aimed at providing university students with experience in logging (core handling, description) and interpreting sedimentary cores from industry wells, techniques though that are common when using cores cut for environmental and other studies. Four different cores from the Taranaki Basin, each about 10-20 m in length, representing deep-water to fluvial depositional environments were used. After a 30 minute introductory PowerPoint presentation on core types, handling and marking techniques, students were divided into groups to view and describe each of the cores. At the end of the day there was a 30 minute wrap-up presentation by the participants on each core.

A three-day geological excursion was held as part of the 7th International Symposium on Submarine Mass Movements and Their Consequences meeting held in Wellington in November 2015. Malcolm Arnot and Greg Browne from GNS Science, together with colleagues Lorna Strachan of the University of Auckland and Sabastian Cardona from Colorado School of Mines were field trip leaders for the trip which started in New Plymouth and ended in Auckland. The seventeen participants came from eight countries and after a delayed start to the trip caused by weather problems for the departing flight from Wellington, all participants enjoyed three fantastic days of geology often to remote parts of the New Zealand coastline to view a range of depositional styles in Miocene-aged deep water mass transport deposits (MTDs). The weather too was great and people seemed to really enjoy the seismic scale of the outcrops we visited. We had two days in north Taranaki looking at outcrops within the Late Miocene Mount Messenger Formation, and the final day was spent north of Auckland looking at Early Miocene deposits at Whangaparaoa Peninsula.

- 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.

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:

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.
