TL;DR: In this article, a meta-model analytic framework is applied to perform sensitivity analysis and explore the interactions of assumptions on model output to derive functional relations that describe the likely contribution the collection of destroyed assets would have made to future production in the Gulf of Mexico.

TL;DR: It is concluded that offshore platform-based mariculture may be commercially viable under favorable assumptions, that its viability requires economies of scale and depends principally on the yield per unit of cage volume achieved.

TL;DR: In this article, the authors reviewed pre-hurricane production and revenue characteristics for the collection of destroyed structures and estimate production at risk, and predicted that 198 million BOE, or nearly 95% of reserves in place, are likely to be redeveloped.

TL;DR: In this article, the authors describe the productivity characteristics of Haynesville Shale wells, project future production from the inventory of active wells, and assess production potential based on drilling scenarios.
Abstract: Louisiana’s Haynesville Shale is one of several unconventional gas plays that have been discovered in the U.S. in recent years and promise to dramatically change the course of future domestic energy development. The Haynesville Shale is the deepest, hottest, and highest pressured shale among the big four plays in the U.S. with drilling and completion cost ranging between $7 and $10 million per well. The average Haynesville well has an initial production rate of 10 MMcfd and declines rapidly, producing 80% of its expected recovery during the first 2 years of production. The purpose of this article is to describe the productivity characteristics of Haynesville wells, project future production from the inventory of active wells, and assess production potential based on drilling scenarios. We offer statistical analysis of the wells drilled to date and construct type profiles to characterize the play. We estimate that the current inventory of Haynesville wells will produce 3 Tcf over their lifecycles, and within the next 3 years, cumulative build-out in the region will range between 3 and 9 Tcf. To maintain current gas production levels in the state, we estimate that about 550 shale gas wells per year will need to be brought online over the next 3 years.

TL;DR: In this article, the authors argue that the switch from coal to natural gas for electricity generation will reduce sulfur, nitrogen, mercury, and particulate air pollution, but the question of whether natural gas will displace coal compared with renewables is open.
Abstract: Unconventional oil and natural gas extraction enabled by horizontal drilling and hydraulic fracturing (fracking) is driving an economic boom, with consequences described from “revolutionary” to “disastrous.” Reality lies somewhere in between. Unconventional energy generates income and, done well, can reduce air pollution and even water use compared with other fossil fuels. Alternatively, it could slow the adoption of renewables and, done poorly, release toxic chemicals into water and air. Primary threats to water resources include surface spills, wastewater disposal, and drinking-water contamination through poor well integrity. An increase in volatile organic compounds and air toxics locally are potential health threats, but the switch from coal to natural gas for electricity generation will reduce sulfur, nitrogen, mercury, and particulate air pollution. Data gaps are particularly evident for human health studies, for the question of whether natural gas will displace coal compared with renewables, and fo...

TL;DR: A review of potential solutions to a range of resource and environmental problems in aquaculture, including novel culture systems, alternative feed strategies, and species choices, and identifying easily adoptable solutions and promising technologies worth further investment.
Abstract: Aquaculture is currently the fastest growing animal food production sector and will soon supply more than half of the world's seafood for human consumption. Continued growth in aquaculture production is likely to come from intensification of fish, shellfish, and algae production. Intensification is often accompanied by a range of resource and environmental problems. We review several potential solutions to these problems, including novel culture systems, alternative feed strategies, and species choices. We examine the problems addressed; the stage of adoption; and the benefits, costs, and constraints of each solution. Policies that provide incentives for innovation and environmental improvement are also explored. We end the review by identifying easily adoptable solutions and promising technologies worth further investment.

TL;DR: It is suggested that the vast amount of space suitable for marine Aquaculture presents an opportunity for countries to develop aquaculture in a way that aligns with their economic, environmental and social objectives and shows that space in coastal areas is unlikely to limit the potential for aquacculture.
Abstract: Marine aquaculture presents an opportunity for increasing seafood production in the face of growing demand for marine protein and limited scope for expanding wild fishery harvests. However, the global capacity for increased aquaculture production from the ocean and the relative productivity potential across countries are unknown. Here, we map the biological production potential for marine aquaculture across the globe using an innovative approach that draws from physiology, allometry and growth theory. Even after applying substantial constraints based on existing ocean uses and limitations, we find vast areas in nearly every coastal country that are suitable for aquaculture. The development potential far exceeds the space required to meet foreseeable seafood demand; indeed, the current total landings of all wild-capture fisheries could be produced using less than 0.015% of the global ocean area. This analysis demonstrates that suitable space is unlikely to limit marine aquaculture development and highlights the role that other factors, such as economics and governance, play in shaping growth trajectories. We suggest that the vast amount of space suitable for marine aquaculture presents an opportunity for countries to develop aquaculture in a way that aligns with their economic, environmental and social objectives.

TL;DR: In this article, the authors present a systematic review and examination of the technical and economic evaluation techniques for the development of shale gas to provide an overview of their current status and suggest that these techniques need to be further improved to assess the economic feasibility of developing shale gas for assisting investment decisions effectively.
