Modelling of hydrogen gas generation from overmature organic matter in the Cooper Basin, Australia

Autor: Christopher J. Boreham, Dianne S. Edwards, Andrew J. Feitz, Andrew P. Murray, Nicolaj Mahlstedt, Brian Horsfield

Publikováno v: The APPEA Journal. 63:S351-S356

A significant portion of planned energy and mineral resource investment into Australia is now for hydrogen (H2). Whether from fossil fuels with carbon capture and storage or from electrolysis of water using renewable energy, there is a price premium

Heavy End Evaluation in Oils and Associated Asphaltene Deposits from Two Adjacent Reservoirs by High-Resolution Mass Spectrometry

Autor: Mareike Noah, Julia Forsythe, Rolando di Primio, Sabine Mehay, Oliver C. Mullins, Nicolaj Mahlstedt, Brian Horsfield

Publikováno v: Energy & Fuels

The formation of viscous oil and tar mats in oilfield reservoirs has substantial consequences in the production of oil. For example, aquifer sweep can be precluded in such an occurrence, impacting field development planning. Several processes can giv

Insights into organic metagenesis using Raman spectroscopy and high resolution mass spectrometry: A case study of the Shahezi formation, deep Songliao basin, China

Autor: Shuangbiao Han, Linfeng Xie, Xin Du, Chaohan Xiang, Jie Huang, Zhiyuan Tang, Chengshan Wang, Brian Horsfield, Nicolaj Mahlstedt

Publikováno v: International Journal of Coal Geology

The maturity of sedimentary organic matter is a key parameter for evaluating oil and gas resources. Existing maturity indicators have different evaluation principles and application scopes. This study investigated samples of high to overmature lacust

Chemostatistic allocation of shale oil production using acidic heterocompounds

Autor: Brian Horsfield, Yuanjia Han, Nicolaj Mahlstedt, Mareike Noah

Publikováno v: AAPG Bulletin

Hydraulic fracturing is routinely used to release and produce petroleum from multistacked shale layers. Although it is known that some shale layers are more productive than others, actually allocating produced oil volumes to individual reservoirs is

Molecular hydrogen from organic sources in geological systems

Autor: Nicolaj Mahlstedt, Brian Horsfield, Philipp Weniger, David Misch, Xiangyun Shi, Mareike Noah, Christopher Boreham

Publikováno v: Journal of Natural Gas Science and Engineering

We have recently shown that molecular hydrogen generation from organic matter occurs at high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the Songliao Basin. To evaluate and extend these implications to a wider range o

Intraformational migration of petroleum: Insights into the development of sweet spot in the Cretaceous Niobrara shale-oil system, Denver Basin

Autor: Heather LaReau, Brian Horsfield, Yuanjia Han, Nicolaj Mahlstedt

Publikováno v: Marine and Petroleum Geology

The Cretaceous Niobrara Formation is one of the latest unconventional exploration targets in North America. In this paper, an overall Type-II marine organofacies with some variability is present within a core which consists of alternating marls and c

PhaseKinetics for assessing the compositional evolution of petroleum generated from the early to Late Miocene source rock, Belait Formation, Brunei-Muara district, Brunei Darussalam

Autor: Aminul Islam, Nicolaj Mahlstedt, Mohamed Ragab Shalaby, Liyana Nadiah Osli

Publikováno v: Journal of Petroleum Science and Engineering

The Early to Late Miocene Belait Formation in Brunei-Muara district has been investigated using the PhaseKinetic approach for compositional petroleum generation kinetics. The source rock characteristics of the selected coal and coaly shale samples in
