Advantage 2014 – Technical Workshops 4th April Venue: GNS Science in Avalon, Lower Hutt
This full day series of workshops presents a unique opportunity to learn more about research conducted by GNS Science on New Zealand Petroleum Systems. The program includes a mix of talks and interactive discussions on a range of topics related to petroleum (and hydrate) exploration in NZ. Some sessions may be run in parallel. There will be opportunities for participants to provide feedback on research directions, scope and priorities.
The day ends with a poster session, with refreshments, followed by a BBQ.
The provisional range of workshop topics and indicative content includes:
- Reservoir Characterisation
- New Zealand oil-oil and oil source rock correlations
- Unravelling charge histories in offshore Taranaki Basin
- Role of faults in petroleum migration
- Frontier Basin Geoscience
- The next decade of scientific drilling expeditions around New Zealand
- Gas Hydrates
Reservoir characterisation: This workshop will include summaries and excerpts of recent work in developing a digital database on the Farewell Formation, incorporating subsurface (well logs, seismic) and outcrop data, to describe reservoir parameters, stratigraphy, and paleogeography. There will also be discussion of a similar initiative for the Kaimiro Formation, as well as reference to availability of a new comprehensive compilation of data on the Mount Messenger Formation.
New Zealand oil-oil and oil source rock correlations: Recently completed petroleum geochemistry database projects at GNS Science have generated a huge amount of new data and knowledge that provide new insights into New Zealand’s complex and commonly enigmatic petroleum systems, particularly in Taranaki. The objectives of this workshop are to: (1) review the petroleum geochemistry databases now available in Petroleum Basin Explorer; (2) examine the chemometrics-based oil-oil and oil-source rock correlations and calibrations of fluid maturities; (3) discuss direct implications for exploration, as a forerunner to broader analysis of Taranaki petroleum systems in a later workshop; and (4) seek input on future priorities for petroleum geochemistry research.
Biostratigraphy: This workshop will present some key advances in the field of biostratigraphy relevant to petroleum exploration, including: (1) recent developments in calibration and biostratigraphic subdivision of the NZ timescale; (2) dating and paleoclimate trends in relation to sea level change and sequence stratigraphy; and (3) Timescale Creator and other reference databases. There will be opportunities to discuss these topics as well as industry requirements in the field of biostratigraphy.
Unravelling charge histories in offshore Taranaki Basin: Recent exploration and scientific research have shed new light on some aspects of offshore Taranaki Basin’s complex geology and in effect, have provided new pieces of what is undoubtedly a very complex 4D puzzle of petroleum plumbing systems. The purpose of this workshop is to critically examine some of these new pieces of evidence aimed at improving our collective understanding of migration pathways and charge histories in some of the key exploration fairways, such as Tui−Maari and Kupe−Kapuni. Aspects considered will include:
- Petroleum fluids – implications from interpretation of source rock age, organofacies and maturity
- Source rock distribution – where are the rich kitchens and what is the critical timing of expulsion?
- Other critical timings − which events control whether charge occurs?
- Petroleum plumbing systems – what controls where the oil and gas are going?
- Fault evolution – barriers, conduits or seals?
- Uplift and erosion − a fresh look into basin inversion, exhumation and fault block movement: how does it affect generation and accumulation of petroleum?
Role of faults in migration: Faults have the potential to retard lateral flow and enhance the vertical movement of fluids. Because faults may trap hydrocarbons and compartmentalise reservoirs it is important to determine how, where and under what circumstances they are likely to influence fluid migration in hydrocarbon systems. The aim of this workshop is to re-examine the methods used to predict the impact of faults on the migration and accumulation of hydrocarbons. Aspects addressed will include:
- Brief summary of the architecture of fault zones and the methods used to predict their likely influence on hydrocarbon migration.
- The applicability of shale smear algorithms and inferences drawn from outcrops in northern Taranaki on the validity of these algorithms.
- Using regional stress data to predict the impact of faults on hydrocarbon migration - including application of these techniques to the southern Taranaki Basin.
- Role of faults as conduits for flow using tunnel data from the central North Island and the relationships of the results to percolation theory.
Frontier Basin Geoscience: The focus of this workshop is an interactive discussion on some of the outstanding (G&G) issues related to New Zealand’s frontier basins (e.g. Reinga-Northland, Deepwater Taranaki, East Coast, and Canterbury-Great South). A set of updated paleogeographic maps will be used to aid discussion, and topics will include a focus on marine source-rock presence and their petroleum-generative potential, especially in East Coast basins.
The next decade of scientific drilling expeditions around New Zealand: GNS Science is currently involved in the leadership of 6 scientific drilling proposals under the International Ocean Discovery Programme (IODP), and in New Zealand's EEZ. These range from early stage pre-proposals to pending scheduled drilling legs using the IODP drill ships Joides Resolution (non-riser) and Chikyu (riser). This workshop will provide delegates with an overview of the scientific objectives, the planned targets and the pre-drilling surveys already acquired and being planned, including a proposed 3D seismic reflection survey. The topics discussed will include: (1) overview of IODP, how it works, and the proposals in the New Zealand region; (2) Lord Howe Rise proposal, scientific objectives, planned targets and the pre-drilling surveys; and (3) Hikurangi Margin legs, scientific objectives, planned drilling targets and 3D seismic survey.
Hydrates: This parallel workshop will run the whole afternoon and include a series of plenary talks in relation to discovery, geotechnical issues and production modelling for hydrates as well as sessions on (1) elements of the Hikurangi Margin gas hydrates petroleum system; and (2) development of the IODP Complementary Project Proposal.
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.

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.
