When the U.S. Department of the Interior released its 1989 estimates of how much undiscovered oil and gas remain in the United States, a controversy ensued. Some members of the petroleum industry charged that the estimates were too low. This book evaluates the scientific credibility of the statistical and geological methods underlying the estimates.

""" This book has been written as a guide to the management and use of formulated feeds in intensive fish and shrimp culture. While its focus is on the use of commercially pro duced feeds in intensive production systems, it is anticipated that many of the practical issues covered will be of equal interest to those fish farmers who make their own feeds and to those who use formulated feeds in less intensive systems. Feeds and feeding are the major variable operating costs in intensive aquaculture and the book is primarily in tended to aid decision making by fish farm managers in areas of feeding policy. The dramatic increases in aquaculture production seen over the past 15 years have been made possible, in large part, by gains in our understanding of the food and feed ing requirements of key fish and shrimp species. A global aquaculture feeds industry has developed and a wide range of specialist feeds is now sold. The new options in feeds and feeding systems, which are becoming available, necessitate continual review by farmers of their feeding policies, where choices must be made as to appropriate feed types and feeding methods. While growth rates and feed conversion values are the prime factors of interest to farmers, other important issues, such as product quality and environmental impacts of farm effiuents, are also directly related to feed management practices.

This book is a guide to the management and use of formulated feeds in semi-intensive and intensive fish and shrimp culture. Feeds represent the major variable operating costs in intensive aquaculture, and optimizing their use represents an opportunity for many farmers to increase or maintain the profitability of their enterprise. Fish farmers have an ever widening range of feed types and feeding methods from which to choose, and must carefully monitor the use of feeds in order to control costs. This book includes details of those biological, environmental, and nutritional factors which influence the feeding, growth and survival of fish and shrimp, and of which some understanding is essential in the establishment of effective feeding practices. Details are given of feed handling and storage methods, and the various methods available for feeding fish are described and their relative methods appraised. Methods for selection of the appropriate feed types, ration sizes, and feeding schedules are included, and details given of how to measure performance of feeding programs. Throughout the text reference is made to key areas of current research, and examples are drawn from different sectors of the industry to illustrate the general principles of feed management.

Presented in this publication are the results of a major study of the petroleum resources of the world as analyzed by Total Petroleum Systems. The distribution and volumes of resources available in these systems are critically important for the future of the world's economies. Geologic insights gained from studying these 149 systems and their constituent assessment units in 128 provinces and 96 countries, exclusive of the United States, allow a new look at petroleum accumulations and the rocks that are intimately associated with them.

Unconventional Petroleum Geology, Second Edition presents the latest research results of global conventional and unconventional petroleum exploration and production. The first part covers the basics of unconventional petroleum geology, its introduction, concept of unconventional petroleum geology, unconventional oil and gas reservoirs, and the origin and distribution of unconventional oil and gas. The second part is focused on unconventional petroleum development technologies, including a series of technologies on resource assessment, lab analysis, geophysical interpretation, and drilling and completion. The third and final section features case studies of unconventional hydrocarbon resources, including tight oil and gas, shale oil and gas, coal bed methane, heavy oil, gas hydrates, and oil and gas in volcanic and metamorphic rocks. - Provides an up-to-date, systematic, and comprehensive overview of all unconventional hydrocarbons - Reorganizes and updates more than half of the first edition content, including four new chapters - Includes a glossary on unconventional petroleum types, including tight-sandstone oil and gas, coal-bed gas, shale gas, oil and gas in fissure-cave-type carbonate rocks, in volcanic reservoirs, and in metamorphic rocks, heavy crude oil and natural bitumen, and gas hydrates - Presents new theories, new methods, new technologies, and new management methods, helping to meet the demands of technology development and production requirements in unconventional plays
