This book chapter examines the social and environmental costs resulting from natural gas exploitation in the Peruvian Amazon basin with a special focus on the case of the ‘Camisea Natural Gas Project Block 88’ in the Peruvian Amazon basin.

This research drew from a comprehensive source of secondary literature data on the Camisea Project Block 88, complemented by an ethnographic research approach based upon observation, conversation and semi-structure interviews with native community members of the indigenous communities of Shivancoreni and Shimmaa in Cusco-Peru.

The study’s findings illustrate that it is evident that the threats from hydrocarbon development endangers the habitat of indigenous communities and accelerate the destruction of the Peruvian Amazon basin. A business commitment towards a sustainable investment approach coupled with reinforcing and adopting appropriate laws and regulations concerning the environmental protection of the Amazon basin are required in order to preserve one of the most diverse and threatened biological place in the world – the Amazon.

The Amazon is the largest natural biodiversity reserve in South America. Yet, it has experienced habitat degradation and displacement of various indigenous tribes of Amazon. As a result, the legacy of indigenous knowledge and the sustenance of indigenous peoples’ habitat are at stake.

This study provides historical context for the hydrocarbon sector of Peru, particularly in the Peruvian Amazon basin. It also provides insights into the Peruvian hydrocarbon law and regulations and the implications, roles and responsibilities of multinational natural gas companies and their environmental impacts of their business operations in Peru.

The purpose of this paper is to develop an easy and robust tool to develop a decision support system (DSS) for the inspection staff of oil pipelines. The aim is to predict “the class” of each spillage, with respect to some relevant variables such as, mechanical failure or system malfunction. The management will then be able to define which pipelines to monitor and to choose the most suitable monitoring policies, based on the decision tree analysis outcome.

A non‐parametric technique based on rule induction is proposed for the identification of the expected spill cause category of cross‐country oil pipelines. In particular, the classification and regression trees approach is used to automatically generate inspection or maintenance decision rules. The analysis that is described is based on an extended database concerning information about spill cause category in cross‐country oil pipelines in Western Europe.

The proposed technique represents an interesting added value tool for the management. The proposed methodology extrapolates rules for determining the expected spill cause category of cross‐country pipelines, depending on the boundary conditions.

The methodology here presented will assist maintenance managers of oil pipeline to better plan maintenance activity. In particular, the procedure makes it possible to determine which parts of a pipeline have to be submitted to a monitoring action or particular protection, with the aim of improving the efficiency and reducing the risk of spillages.

Effective planning, coordination, and scheduling of the maintenance function can be, and for many years was, accomplished without computer support. The proposed procedure may be included in an information systems tool (sound Computerized Maintenance Information Management System (CMMIS)), for more efficient and effective maintenance/inspection scheduling activities.

The purpose of this paper is to review oil spill incidents and pipeline vandalism in Nigeria between 1970 and 2006 and to examine the potential danger posed by such activities to public health.

The approach adopted to achieve this objective is questionnaire administration on health impacts. Also secondary sources of information come from textbooks and journals. However, data from natural resources exploitation and hazards are collated and analyzed.

It is evident that, out of the 1,000 reported oil spill incidents analyzed, some hundreds of thousands of barrels of oil are lost to the environment. Graphic pictures of typical oil spill through acts of vandalism in Ishiagu, Ebonyi State, Nigeria are analyzed and reviewed. The run‐off and sedimentation of this pollutant in fresh water systems severely degrade water quality, affect fish spawning and aquatic invertebrates' habitats, thus lowering food web productivity. Incidentally the spill‐over effect on humans who directly depend on fish and other aquatic food as an alternative protein supplement is quite inundating. The effects on humans include irritation, dermatitis, cancer, occurrence of abortion, organ failure and genetic disorder.

The limitations encountered in this research work include logistics problems, poor response and uncooperative attitude from respondents, transportation difficulties and restricted access to impacted sites by law enforcement agents and funding. Therefore subsequent researchers in this area should be equipped adequately with both the necessary protective gadgets and increased funding to meet challenges of this nature.

The practical implication of the study is that oil spill incidents should be documented and reported early enough for prompt attention by the regulatory agencies in order to protect and enhance the quality of the environment.

The value of the paper is that oil spill and pipeline vandalization devastate the environment, pollute dependable potable water sources such as streams and rivers and should be seen as a serious threat and negation to the attainment of the United Nations Millennium development goals.

The research activity presented in this paper has the objective of developing models for the evaluation of technological risk and loss of production due to failures, which are among the criterions that enable the choice of optimal scenarios for energy supply. This activity is based on the European Project “Risk of Energy Availability: Common Corridors for Europe Supply Security” (REACCESS), which aims to develop an analytical tool to analyse scenarios for future secure European Union (EU) energy supply.

The paper proposes an innovative approach, since nowadays a generalised analytic model for risk assessment in large‐scale energetic systems does not exist. In particular, the methodology adopted includes models to assess risk for people safety, risk for the environment and availability for corridors and the related infrastructures. As regards technological risk, accidents producing loss of lives in the population and environmental damage are taken into account; while for the loss of production primary attention is paid to technical failures and maintenance.

Since the analytic models developed perform a large‐scale assessment, they must be flexible and simplified to adapt to different situations and to be easily updated when different future scenarios are investigated. Details of the analysis depend on the precision of data collected and inserted in the models. The damage assessment is affected by deficiency and uncertainties related to territorial and statistical data. Nevertheless, the outcomes obtained for each energy commodity are reasonable and often comparable to literature data.

Based on this study output, technological risk can be considered, more systematically than in the past, in the selection of EU strategies for future energy supply. The corridors social cost is included in future strategies selection, in addition to purely economical and environmental evaluations.

This study aims to develop a framework that enables the identification of sustainability factors from industry-specific environmental issues, and it proposes that these factors, in turn, can influence the corporate environmental performance (CEP) of firms in such an industry. It also validates the factor identification aspect of the framework.

The paper starts by reviewing relevant literature extensively and then developing an issue-based environmental sustainability framework to highlight the structural relationship of industry-specific sustainability factors with CEP. By involving 131 participants from academics in Niger Delta, the paper uses exploratory factor analysis techniques to reduce industry-specific sustainability factors from several environmental and socio-economic issues in the Nigerian oil and gas (O&G) industry.

Environmental risk originates from business environmental issues, and it triggers community reaction, which impacts negatively on corporate image. The nature of firm’s strategic responsiveness to these factors determines CEP.

The study draws from the perspectives of academics on environmental issues in Niger Delta to validate the factor identification aspect of the framework. The views of other stakeholders are not included, and hence, it should be applied with caution.

Useful in identifying and managing industry-specific environmental issues, and thus, achieving some sustainable development objectives.

Although most previous studies have focused on generic CEP drivers, this study proposes sustainability factors that can originate from industry-specific environmental issues as crucial drivers of CEP in such an industry. It provides empirical evidence of such credible sustainability factors emerging from the Nigerian O&G industry’s environmental issues.

The key purpose of conducting this review is to identify the issues that affect the structural integrity of pipeline structures. Heat affected zone (HAZ) has been identified as the weak zone in pipeline welds which is prone to have immature failures

In the present work, literature review is conducted on key issues related to the structural integrity of pipeline steel welds. Mechanical and microstructural transformations that take place during welding have been systematically reviewed in the present review paper.

Key findings of the present review underline the role of brittle microstructure phases, and hard secondary particles present in the matrix are responsible for intergranular and intragranular cracks.

The research limitations of the present review are new material characterization techniques that are not available in developing countries.

The practical limitations are new test methodologies and associated cost.

The fracture of pipelines significantly affects the surrounding ecology. The continuous spillage of oil pollutes the land and water of the surroundings.

The present review contains recent and past studies conducted on welded pipeline steel structures. The systematic analysis of studies conducted so far highlights various bottlenecks of the welding methods.
