The influence of convergent margin structure on deep-water stratigraphic architecture, pore pressure evolution, and source rock maturation in the East Coast Basin, New Zealand
Abstract/Contents
- Abstract
- The East Coast Basin of the North Island, New Zealand contains active petroleum systems and has been explored intermittently since the late 1800s. Despite a few small discoveries, the basin is non-commercial largely due to stratigraphic and structural complexities associated with its development on the Hikurangi convergent margin. The major petroleum system risks are the presence of reservoir rock and good potential, mature source rock. Additionally, high overpressures have caused significant drilling problems, representing both a financial burden and a safety hazard for exploration. This dissertation investigates the petroleum system elements and processes of the East Coast Basin, and outlines the importance of convergent margin structure on reservoir architecture, overpressure generation and distribution, and source rock maturation. Each of the three chapters addresses aspects of the petroleum system. Chapter 1 focuses on the reservoir rock though stratigraphic and architectural analysis of an outcropping deep-water turbidite deposit, representing a reservoir analog for the basin. Chapter 2 establishes the structural and stratigraphic framework for the basin through geologic time, providing a means to understand and predict the development of overpressure. Lastly, Chapter 3 assesses the source rock maturation in the East Coast Basin through evaluation of the paleo-basal heat flow and structurally-controlled burial history. This dissertation integrates data from a variety of disciplines (sedimentology, structure, geomechanics, geochemistry) and scales (well samples, well logs, outcrop, seismic data) in order to provide a robust basin analysis of the East Coast Basin.
