This dataset is based on U.S. Geological Survey (USGS) resource assessments for “undiscovered” natural gas liquid resources, which are resources that have not yet been extensively proven by drilling (USGS 2014). Individual resource assessments describe the amount of petroleum resources in units with similar geologic features. We quantified the density of natural gas liquid resources by adding together the amounts in spatially overlapping assessment units and dividing these totals by polygon areas. Since assessments for geologic areas used in this analysis were completed at various times, the certainty related to these values is likely to vary according to geologic unit. USGS [U.S. Geological Survey]. 2014. Energy...
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)...

This data release contains the boundaries of assessment units and input data for the assessment of continuous oil and gas resources in the Delle Phosphatic Member of the Mississippian Woodman Formation, western Utah, eastern Nevada and southeastern Idaho. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar...
