Summary This paper presents case studies focused on the interpretation and integration of seismic reservoir monitoring from several fields in conventional offshore and deepwater Niger Delta. The fields are characterized by different geological settings and development-maturity stages. We show different applications varying from qualitative to quantitative use of time-lapse (4D) seismic information. In the first case study, which is in shallow water, the field has specific reservoir-development challenges, simple geology, and is in phased development. On this field, 4D seismic, which was acquired several years ago, is characterized by poor seismic repeatability. Nevertheless, we show that because of improvements from seismic reprocessing, 4D seismic makes qualitative contributions to the ongoing field development. In the second case study, the field is characterized by complex geological settings. The 4D seismic is affected by overburden with strong lateral variations in velocity and steeply dipping structure (up to 40°). Prestack-depth-imaging (PSDM) 4D seismic is used in a more-qualitative manner to monitor gas injection, validate the geologic/reservoir models, optimize infill injector placement, and consequently, enhance field-development economics. The third case study presents a deep offshore field characterized by a complex depositional system for some reservoirs. In this example, good 4D-seismic repeatability (sum of source- and receiver-placement differences between surveys, dS+dR) is achieved, leading to an increased quantitative use of 4D monitoring for the assessment of sand/sand communication, mapping of oil/water (OWC) front, pressure evolution, and dynamic calibration of petro-elastic model (PEM), and also as a seismic-based production-logging tool. In addition, 4D seismic is used to update seismic interpretation, provide a better understanding of internal architecture of the reservoirs units, and, thereby, yield a more-robust reservoir model. The 4D seismic in this field is a key tool for field-development optimization and reservoir management. The last case study illustrates the need for seismic-feasibility studies to detect 4D responses related to production. In addition to assessing the impact of the field environment on the 4D- seismic signal, these studies also help in choosing the optimum seismic-survey type, design, and acquisition parameters. These studies would possibly lead to the adoption of new technologies such as broad-band streamer or nodes acquisition in the near future.

Abstract How does religion or worldview affect business practices and ethics? This tradition of inquiry goes back, at least, to Max Weber who, in the Protestant Ethic and the Spirit of Capitalism, explored the impact of theological suppositions on capitalist economic development. But the connection can also go the other way. So the focus of inquiry can become: How does business ethics or practices affect ethics in a given nation or corporation? This paper inquires into how the political and economic conditions created and sustained by nineteenth-century trading community in the Niger Delta influenced religious practices or ethics of Christian missionaries. This approach to mission study is necessary not only because we want to further understand the work of Christian missions and also to tease out the effect of business ethics on religious ethics, but also because Christian missionaries came to the Niger Delta in the nineteenth century behind foreign merchants.

In this chapter we highlighted the impact of the current economic and political dispensation in Nigeria and its impact on teacher education programs and the means of enhancing teacher education in the Niger Delta region. This paper is a conceptual and methodological breakthrough in Nigeria's academic landscape where qualitative and quantitative experiences highlight issues that are pertinent to teacher education program in the Niger Delta. The chapter proposed that the Niger Delta region's and the entire Nigeria's teacher education programs would be advanced if the component parts of the current economic and political disposition are resolved. This chapter contends that the Niger Delta region has the potential to address the challenges currently faced in the region such as social disruption (violence threat), poverty, hunger, disease, conflict, marginalization, and the achievement and improvement for effective teacher education programs. This chapter is of the immense judgment that successfully addressing the challenges currently faced in the Niger Delta region, teacher education programs will greatly improve qualitatively and quantitatively.

Media reports on Niger Delta (Henceforth, ND) conflicts have reflected a relationship between lexico-stylistic choices and media ideologies. The existing media studies on the discourse have predominantly utilised pragmatic, stylistic and discourse analytical tools in presenting and labelling discourse participants and/or their ideologies, but neglected how media ideologies can be revealed through lexico-stylistic choices made in the reports. This paper therefore examines the lexico-stylistic choices in the reports in order to establish their link to specific ideological goals of the newspapers in relaying the conflict news. Forty reports on ND conflicts, published between 2003 and 2007, sampled from two ND-based (The Tide and Pioneer) and two national (The Punch and THISDAY, labelled) newspapers, were subjected to stylistic and critical analyses, with insights from structural (relational) semantics and aspects of stylistics discourse. Two broad lexical stylistic choices are identified, including paradigmatic (61.8%—indexed by synonymous, antonymous, hyponymous, colloquial, and register items, and coinages) and syntagmatic (38.2%—marked by collocations, metaphors, pleonasms, and lexical fields) features. The features are utilised for three ideological ends; namely, picking out and framing participants as perpetrators of the violence in the discourse, evaluating specific entities and their roles in the conflicts, and reducing the impact of the activities of the news actors. Although there are overlaps, the evaluative ideology is largely associated with the national newspaper, the impact reduction ideology with the ND-based newspapers, while the framist ideology is observed in the two sets of newspapers. With these findings the study has added the lexical stylistics angle to the existing scholarship on ND conflict news discourse. Thus, the newspaper reports on ND conflicts are motivated by their ideological goals to change the reader’s outlook on the issues relating to the conflicts.

The Impact

Levels of heavy metals (mercury, chromium, lead, cadmium and iron) in the water snail (Pilaovata) in the river nun downstream of Yenegoa Town, south-south Nigeria and other parameters (temperature, ph,turbidity, Total Dissolved Solids TDS, oil and grease) in the water column was investigated in an attempt to understand the impact of urbanization and poor waste management practices on downstream communities in non-oil impacted communities in the Niger delta of Nigeria. While mercury was very minute, iron and chromium where within standards for food in the snail, lead (26-27.4 mg/l), cadmium (12.11--12.16 mg/l) and arsenic (6.92-8.41mg/l) concentrations where above the standards for food sources. Turbidity in the water column was above recommended levels for drinking water, aesthetics and aquatic health. The study concludes that the area may also have lost its capacity to support good fish production, and the water source has become a dangerous source of food and water to inhabitants due to hydrocarbon and heavy metal concentrations. Government intervention and environmental education is recommended.
