Numerous research results have been published on the storage science and technology of CO2 in saline aquifers to address knowledge gaps identified by IPCC Special Report Carbon Capture Storage 2005. Significant progress has made towards developing consistent methodologies for classification determination capacity comprehensive guidelines regarding site selection, characterisation, risk assessment monitoring plans. Although advancements with respect geochemical processes numerical...
We present new interpretations and mapping that define the distribution, extent, sediment thickness of 25 primarily offshore sedimentary basins within New Zealand's Exclusive Economic Zone (EEZ) Extended Continental Shelf (ECS). These cover ∼1.64 million km2 ∼5.8 (∼28%) territory. The formed in different tectonic settings. Most initially during mid- to Late Cretaceous either a rift-related setting Gondwana break-up, or atop paleo subduction margin. Others due onset mid-Paleogene sea-floor...
Abstract Three-dimensional (3D) seismic data reveal the complex interplay between surface topography of a c. 4405 km 3 mass transport deposit (MTD) and overlying sedimentary packages over approximately last two million years. The image part Pleistocene to recent shelf slope basin-floor Giant Foresets Formation in offshore western New Zealand. MTD created substantive topographic relief rugosity at contemporaneous seabed, formed by presence shallow basal detachment surface, very large (up 200...
Clay- and lithic-rich sandstones are difficult to characterize through uncored well sections in terms of their grain size, porosity, mineralogy, all which required for assessing reservoir quality production performance. This paper presents results from a study one such interval shows how combination different techniques can be used better understand rock properties complex reservoirs, thereby helping reduce uncertainty. In this study, mean data laser grain-size analysis comparable...
Abstract This paper describes a multidisciplinary integrated workflow for mapping Late Cretaceous to Recent subsurface structure and stratigraphy, modeling petroleum systems of the Taranaki Basin (74,209 km2), New Zealand. The basin-scale assessment geology fluid flow is aimed improve previous, mostly local, studies. size study area integration over nine-year timeframe large datasets, multiple software disciplines present technical challenges. consists following six main tasks: data...
New LA–ICP–MS U–Pb zircon ages of tuffs, from the northern Taranaki coastal section constrain depositional Mount Messenger Formation to 9.69 ± 0.12 and 9.43 0.17 Ma at Mohakatino Tongaporutu rivers, respectively, Urenui near Waiau Stream 8.45 0.10 Ma. Our preferred new radiometric–biostratigraphic age model comprises lower upper intervals characterised by relatively low high un-decompacted sedimentation rates 102 96 m/Ma (MSWD = 6.0) 1358 144 1.32), respectively. The poor linear fit interval...
A high resolution 3D geological model of the Taranaki Basin, New Zealand's only hydrocarbon producing province, has been completed as part multi-phase, multi-disciplinary 4D Project at GNS Science. The covers an area c. 74,000 km2 and is based on interpretation up to 17 regionally mapped seismic reflection horizons spanning from Late Cretaceous Plio-Pleistocene. Horizons were tied 42 exploration wells, which further used develop a regional velocity model. result digital atlas basin complete...
A resurgent interest in the gas potential of Gulf Papua has been enhanced by recent announcement developing new LNG facilities Port Moresby. Petroleum Geo-Services (PGS) recently acquired a 6,000-km2Multi-Client 3D (MC3D) survey gulf. Although most discoveries PNG are from highland areas, gulf is proven hydrocarbon province with gas/condensate accumulations previously discovered several reef build-ups. It thought that sediments Papuan Fold Belt produced clastic dominated deltas area. this...
The discovery of the giant Maui gas-condensate field in 1969 initiated a long history petroleum exploration offshore Taranaki Basin. large was followed by many smaller finds but also very number dry wells through to present-day. Factors controlling prospectivity are still insufficiently understood despite 400 being drilled. Recent remapping southern Basin as part GNS Science 4D project has identified rapid changes basin evolution and illustrated structural complexity basin. Heterogeneities...
