The paper traces the manner in which an obligation came to be imposed on select industries, requiring them to take account of amenity, wildlife and outdoor-recreational interests in the course of preparing and carrying out developmental schemes. Under pressure from the relevant voluntary bodies, the statutory obligations, first imposed on hydro-electric power development, were generalized to cover 'whole' industries, and then, under the Countryside Acts of 1967-68, were extended to all State utilities. The recent privatization of those industries has provided a further pretext for extending and strengthening the 'amenity' clause. The approach has provided important insights into how industry itself might become...
Woodland caribou (Rangifer tarandus caribou) in Alberta are classified as endangered and apparently have declined. Disturbance from petroleum exploration has been implicated as a possible cause, so we constructed a simple model to estimate the energy costs of multiple encounters with disturbance (i.e., loud noise). Our objective was to estimate if woodland caribou in northeastern Alberta have been exposed to enough disturbance from 1988 to 1993 to cause winter mass loss to exceed either (i) 15% autumn mass or (ii) 20% autumn mass. A single disturbance event costs caribou 3.46-5.81 MJ. Caribou would have to encounter (i) 20-34 (mean = 27) disturbance events to lose >15% mass over winter and (ii) 41-137 (mean = 89)...
How much does real GDP respond to unanticipated changes in the real price of oil? Commonly used censored VAR models suggest a substantial decline in real GDP in response to unexpected increases in the real price of oil, yet no response to unexpected declines. We show that these estimates are invalid. Based on a structural model that encompasses both symmetric and asymmetric models as special cases, correctly computed impulse responses are of roughly the same magnitude in either direction, consistent with formal tests for symmetric responses. We discuss implications for theoretical models and for policy responses to energy price shocks.
This article provides a comprehensive and succinct review of the essentials needed to deal with the disputes encountered in the international energy sector. It begins with explaining the reasons why this sector has more disputes than any other business sector and then discusses how parties can effectively manage that risk. The article covers the kinds of disputes found in the international O&G business, the types of dispute resolution mechanisms available along with their respective advantages, and the legal framework for international arbitration. It explains how to properly draft dispute resolution clauses and what to consider in selecting counsel and in appointing arbitrators. A section is included that specifically...

The time frame for natural attenuation of crude oil contamination in the subsurface has been studied for the last 27 years at a spill site located near Bemidji, Minnesota, USA. Data from the groundwater contaminant plume show that dissolved benzene concentrations adjacent to the oil decreased by 50% between 1993 and 2007. To assess how this decrease is related to benzene concentrations in the crude oil, samples of oil were bailed from floating oil in five wells and analysed for volatile components. Compared to reference oil collected from the pipeline in 1984, benzene concentrations in the well located farthest downgradient in the oil have decreased an average of 50%. Benzene and ethylbenzene depletion are linearly...

Globally, bioremediation is a common choice for remediation of petroleum hydrocarbon-contaminated sites. For application at cold climate sites, bioremediation approaches are appealing because they have potential to be more efficient and cost-effective than alternative, more energy intensive approaches. Several bioremediation approaches have been reported to be successful for petroleum hydrocarbon-contaminated soils at cold climate sites. In contrast, there are relatively few publications on applications of bioremediation for petroleum-contaminated groundwater at cold climate sites. Most of the existing relevant groundwater studies were conducted at sites with either no permafrost, or with sporadic to discontinuous...
