Migration Pathways

Understanding the CO2 storage potential and petroleum prospectivity of the Gippsland Basin are critical to managing the resources of this region. Key controls on determining the prospectivity for CO2 storage and petroleum include understanding the fluid migration history and reservoir characteristics in the basin. Gippsland Basin hydrology, reservoir characteristics and petroleum systems are being studied to better understand how CO2 can be safely stored in the subsurface. Hydrocarbon migration pathways have been delineated using petroleum systems modelling. The latest hydrocarbon charge history data has been acquired to test the containment potential of individual structures along these migration pathways. The charge history results indicate the Golden Beach gas field has had a complex hydrocarbon fill history, and that early charge has migrated through the regional seal. The results also indicate that early oil charge was very common in the basin, including large structures that are now filled with gas (e.g. Barracouta). The results allow the regions with good CO2 containment potential to be delineated for further storage investigations. A new evaluation of the reservoir characteristics of the Latrobe Group—through porosity/permeability analysis and automated mineral analysis (AMA)—has provided insights into CO2 injectivity and capacity. The AMA results constrain the mineralogy and diagenetic history of the reservoirs and seals. In addition, the data highlights the presence of carbonates, glauconite and K-feldspar that are potentially reactive with injected CO2.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Stemmerik, L., Dam, G., Noe-Nygaard, N., Piasecki, S., & Surlyk, F. (1998). Sequence stratigraphy of source and reservoir rocks in the Upper Permian and Jurassic of Jameson Land, East Greenland. Geology of Greenland Survey Bulletin, 180, 43-54. https://doi.org/10.34194/ggub.v180.5085 _______________ Approximately half of the hydrocarbons discovered in the North Atlantic petroleum provinces are found in sandstones of latest Triassic – Jurassic age with the Middle Jurassic Brent Group, and its correlatives, being the economically most important reservoir unit accounting for approximately 25% of the reserves. Hydrocarbons in these reservoirs are generated mainly from the Upper Jurassic Kimmeridge Clay and its correlatives with additional contributions from Middle Jurassic coal, Lower Jurassic marine shales and Devonian lacustrine shales. Equivalents to these deeply buried rocks crop out in the well-exposed sedimentary basins of East Greenland where more detailed studies are possible and these basins are frequently used for analogue studies (Fig. 1). Investigations in East Greenland have documented four major organic-rich shale units which are potential source rocks for hydrocarbons. They include marine shales of the Upper Permian Ravnefjeld Formation (Fig. 2), the Middle Jurassic Sortehat Formation and the Upper Jurassic Hareelv Formation (Fig. 4) and lacustrine shales of the uppermost Triassic – lowermost Jurassic Kap Stewart Group (Fig. 3; Surlyk et al. 1986b; Dam & Christiansen 1990; Christiansen et al. 1992, 1993; Dam et al. 1995; Krabbe 1996). Potential reservoir units include Upper Permian shallow marine platform and build-up carbonates of the Wegener Halvø Formation, lacustrine sandstones of the Rhaetian–Sinemurian Kap Stewart Group and marine sandstones of the Pliensbachian–Aalenian Neill Klinter Group, the Upper Bajocian – Callovian Pelion Formation and Upper Oxfordian – Kimmeridgian Hareelv Formation (Figs 2–4; Christiansen et al. 1992). The Jurassic sandstones of Jameson Land are well known as excellent analogues for hydrocarbon reservoirs in the northern North Sea and offshore mid-Norway. The best documented examples are the turbidite sands of the Hareelv Formation as an analogue for the Magnus oil field and the many Paleogene oil and gas fields, the shallow marine Pelion Formation as an analogue for the Brent Group in the Viking Graben and correlative Garn Group of the Norwegian Shelf, the Neill Klinter Group as an analogue for the Tilje, Ror, Ile and Not Formations and the Kap Stewart Group for the Åre Formation (Surlyk 1987, 1991; Dam & Surlyk 1995; Dam et al. 1995; Surlyk & Noe-Nygaard 1995; Engkilde & Surlyk in press). The presence of pre-Late Jurassic source rocks in Jameson Land suggests the presence of correlative source rocks offshore mid-Norway where the Upper Jurassic source rocks are not sufficiently deeply buried to generate hydrocarbons. The Upper Permian Ravnefjeld Formation in particular provides a useful source rock analogue both there and in more distant areas such as the Barents Sea. The present paper is a summary of a research project supported by the Danish Ministry of Environment and Energy (Piasecki et al. 1994). The aim of the project is to improve our understanding of the distribution of source and reservoir rocks by the application of sequence stratigraphy to the basin analysis. We have focused on the Upper Permian and uppermost Triassic– Jurassic successions where the presence of source and reservoir rocks are well documented from previous studies. Field work during the summer of 1993 included biostratigraphic, sedimentological and sequence stratigraphic studies of selected time slices and was supplemented by drilling of 11 shallow cores (Piasecki et al. 1994). The results so far arising from this work are collected in Piasecki et al. (1997), and the present summary highlights the petroleum-related implications.

Migration history has made some major leaps forward in the last fifteen years or so. An important contribution was Leslie Page Moch's Moving Europeans, published in 1992, in which she weaves the latest insights in migration history into the general social and economic history of western Europe. Using Charles Tilly's typology of migration patterns and his ideas on the process of proletarianization since the sixteenth century, Moch skilfully integrates the experience of human mobility in the history of urbanization, labour relations, (proto)industrialization, demography, family history, and gender relations. Her state-of-the-art overview has been very influential, not least because it fundamentally criticizes the modernization paradigm of Wilbur Zelinsky and others, who assumed that only in the nineteenth century, as a result of industrialization and urbanization, migration became a significant phenomenon. Instead, she convincingly argues that migration was a structural aspect of human life. Since then many new studies have proved her point and refined her model.

Written Sources

It is well known that indigenous contemporary written documentation exists for the precolonial and early colonial history of some of the coastal societies of South-Eastern Nigeria. The best known example is Old Calabar, for which there exists most notably the diary of Antera Duke, covering the years 1785-88, a document brought from Old Calabar to Britain already during the nineteenth century. More recently John Latham has discovered additional material of a similar character still preserved locally in Old Calabar, principally the Black Davis House Book (containing material dating from the 1830s onwards), the papers of Coco Bassey (including diaries covering the years 1878-89), and the papers of E. O. Offiong (comprising trade ledgers, court records, and letter books relating to the period 1885-1907). In the Niger Delta S. J. S. Cookey, for his biography of King Jaja of Opobo, was able to use contemporary documents in Jaja's own papers, including correspondence from the late 1860s onwards. In the case of the neighboring community of Bonny (from which Jaja seceded to found Opobo after a civil war in 1869), while earlier historians have alluded to the existence of indigenous written documentation, they have done so only in very general terms and without any indication of the quantity or nature of this material.

Humans and elephants have historically shared the forested mountain ranges of Zomia, a geography defined by the regular movement of people and an ecology shaped by the movement of its elephant population. This article will examine how free-roaming elephant pathways facilitated human mobility in the highlands defining the Indo-Myanmar border. It will analyze the more-than-human agency that emerges when following elephant trails and the varying role this forest infrastructure might have played in the social and political history of the region. The article will explore two historical examples. First, the migration of a Lisu community in Upper Myanmar who utilized elephant paths to navigate their passage. Second, how the British Empire exploited a network of elephant-human tracks to subjugate the peoples living in Mizoram, northeast India. In these regions the patterns of migration, history of colonization, and identities and practices of communities must be understood in relation to wild elephants.

Oil was discovered in large quantities in Nigeria in 1956 and exploration began in the same year. Before oil, agriculture and fishing had assured the Niger Delta people of a bright future. Since 1956, oil has been extracted from the Niger Delta with destructive consequences on the environment, bringing about environmental degradation and destruction of the people’s primary means of livelihood. Land and water were badly polluted, and the health of the people affected because of leaks from oil pipelines, gas flaring and acid rains. Several petitions and non-violent protests by Delta communities, women and youth against environmental destruction failed to receive attention. Rather, opposition to peaceful protests earned the people military invasions of their communities, clampdowns and jailings. The rise of militarism and terrorism in the Niger Delta was the result of the Federal Government and Oil Companies’ clampdown on non-violent protests for environmental justice in the Niger Delta. This paper discusses the history of oil exploration in the Niger Delta, oil laws, effects of oil exploration in the region, and the rise of militants and terrorists in the area. The paper uses the term, ‘environmental Justice’ to denote unfair treatment and destruction of the Delta environment resulting from oil exploration, non implementation and enforcement of environmental laws and regulations, and abuse of human rights.The paper suggests solutions for peace in the Niger Delta.
