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 Eight latest Eocene to earliest Miocene stratigraphic surfaces have been identified in petroleum well data from the Taranaki Basin, New Zealand. These define seven regional sedimentary packages, of variable thickness and lithofacies, forming a mixed siliciclastic–carbonate system. The evolving tectonic setting, particularly initial development Australian–Pacific convergent margin, controlled geographic, facies variability. This signal overprinted transgressive trend that culminated...
This paper presents a reappraisal of datasets from Titihaoa-1, an offshore petroleum exploration drillhole that intersects ∼2740 m-thick Holocene to early-middle Miocene sedimentary succession in the Titihaoa Sub-basin, part Hikurangi accretionary wedge. The well provides important datapoint southern subduction margin. We present new and revised foraminiferal biostratigraphic paleoenvironmental interpretations help constrain age, depositional paleo-water depths, sedimentation rates,...
This integrated study focuses on the reservoir characteristics of East Coast and Pegasus basins, located on- offshore eastern North Island, New Zealand. The compilation existing GNS Science knowledge data includes paleogeographic maps, seismic interpretations, petrophysical analysis both conventional wireline FMI image logs in exploration wells, poroperm potential likely Neogene Cretaceous formations, found onshore parts basins. Integration onshore/outcrop analogues with subsurface sets...
Understanding the in-situ stress field in subsurface provides insights on tectonic processes and seismic hazards of a basin. This paper presents observations interpretations present day maximum horizontal (SHmax) orientation from well Ranui-2 located onshore southern East Coast Basin. Fractures identified image log have been divided into distinct subsets based fracture orientation. These correspond general sense, to changes lithology well, which are associated with formations. Analysis shows...
This study provides the first New Zealand-wide assessment of hydrocarbon seal rock potential twenty sedimentary basins and is designed to help evaluate pre-drill risk assessment. Seal quality has been assessed using key petroleum wells seismic lines. Deep-sea drilling research holes provide glimpses stratigraphy in some more distal basins. The Taranaki Basin currently Zealand's only producing basin — all others are frontier many have no or few exploration rather sparse coverage. We produced...
Hydrocarbon exploration on the East Coast of North Island has not yet yielded significant commercial reserves, even though elements a working petroleum system are all present (Field et al, 1997). Exploration focussed shallow, Neogene part succession, built up during plate margin convergence over last ∼24 million years. Convergent margins generally characterised by low-total organic carbon (TOC) source rocks and poor clastic reservoir quality due to sorting labile grains. However,...
Summary Murphy Oil Company operates a number of mature oil and gas fields in the Sarawak Basin, Malaysia. It has been utilizing new generation pulsed neutron tool ("PNT") to help track production related fluid changes identify bypassed oil. This paper summarizes case studies from 2 wells, using PNT for saturation logging interpretation, benefits identified. Field A results include identification displaced gas-leg basal swept zone. The well was successfully recompleted original with 1000 BOPD...
<p>Determining the potential for faults to slip is widely employed evaluating fault and associated earthquake hazards, characterising reservoir properties. Here we use borehole 3D seismic reflection data estimate stress orientations magnitudes, geometries tendency in southern Taranaki Basin, New Zealand. We highlight uncertainties maximum horizontal (SHmax) magnitude calculations from breakout width rock strength. As other settings, uncertain on resistivity images because one...
