This book is about exploration for oil and gas and focuses particularly on seismic exploration in the hunt for hydrocarbons. The first part, "The Hunt for Hydrocarbons," gives general background informa tion, with an introductory chapter on the beginnings of the oil business followed by three chapters that in clude elements of petroleum geology, geophysical methods, and drilling and logging. The second part, "Seismic Exploration for Hydrocarbons," consists of two chapters that describe rudiments of the seismic method and velocity measurements; two chapters dis cussing theory based on wave propagation and the convolutional model; and a chapter devoted to each of the three phases of seismic exploration: acquisi tion, processing, and interpretation. I have concen trated on seismic exploration because most of the oil and gas that has been found has been located by this method, and it is the only method that has the poten tial for the increased precision needed in what Hal bouty (1982) calls "the deliberate search for the subtle trap. " In contrast to elementary and introductory books that present the seismic method superficially and qualitatively, this book develops the method quanti tatively, using only elementary mathematics (algebra and trigonometry), so that readers should be able to do things afterwards that they couldn't do before, and thereby get a deeper appreciation of the business of hunting for hydrocarbons. The book also probes into some sophisticated topics that wouldn't be mentioned IX x use in short courses at a variety of levels.
“Provides an incredible insight into not only the majestic and beautifully lined Hunter, but also to RAF operations in insurgent wars.” —Flight Line Book Review Based on official records held at the National Archives and other published sources, Hunters over Arabia presents an in-depth account of the operations performed by the Hawker Hunter squadrons policing the desert wastelands and high mountain ranges of the Middle East. Copiously illustrated with color and black and white photographs, a high percentage of operations performed by this versatile British ground attack and reconnaissance fighter are described in detail. Using a chronological format, the narrative focuses on the period during which the Hunter served in the Middle East, from 1960 to 1971. Further chapters are dedicated to the three Hunter variants most closely associated with the Middle East, the FGA.9, FR.10 and T.7, together with their respective allocation dates. A short background to Aden, its historical links to Britain, and RAF airfields administered by Middle East Command complete this factual account. “Will be referenced for years to come as the authoritative source of operations across the troubled Middle East at the end of British influence.” —Aircrew Book Review “Fantastic color and black and white images and beautifully written with great use of National Archive documentation. This book will thrill and inform all enthusiasts of the Hawker Hunter.” —Vintage Airfix
Author Ray Hunziker, longtime editor of Tropical Fish Hobbyist magazine and lifelong fish keeper, is the ideal tutor for aquarists looking to take a dive into the saltwater end of the tank! Marine Aquariums begins with a discussion of seawater and water quality, the most critical part of keeping marine fishes happily swimming (and breathing) in their tank. Hunziker continues with a step-by-step explanation of setting up a marine aquarium, discussing aquarium types, the number of fishes for the size tank selected, siting the tank, stands, substrates, temperature, lighting, filtration and décor. The chapter on stocking and maintaining the tank discussing purchasing healthy, vibrant fish, acclimatizing them to the tank, feeding them, and monitoring the tank on a regular basis. An elaborate chapter on the various types of saltwater fishes available, “Ideal Fish for Your Marine Aquarium, “details and illustrates nearly 70 fishes divided into the following categories: moray eels, squirrelfish and soldierfish, lion fish, groupers, cardinalfish, butterflyfish, angelfish, damselfish, hawkfish, wrasses, jawfish, gobies, surgeonfish, and triggerfish. The final chapter discusses keeping fish healthy, including the signs of illness, treating various ailments, and setting up a quarantine tank for affected fish. Resources, glossary, index included.
In the fall of 1978 Ray Ordorica packed everything he thought he would need into his Toyota LandCruiser and drove north to Alaska. He came to a land he had never seen, to find something he wasn't even sure existed: a wilderness cabin he could use for a year or more to live, think, relax, read, and write. Ordorica found his cabin, fixed it up, and, although it was just an un-insulated 12- by 16-foot one-room log structure, he spent three winters in it in relative comfort. Ordorica’s life in that cabin fulfilled a dream he had had for more than ten years. During his long winters in Alaska, it occurred to him that there must be many others who have put off an extended wilderness visit to out of ignorance or fear. They have as many questions about Alaska as he had before he arrived: How do you cope with 40 below? How do you get water? Is it totally dark in mid-winter? These questions and many more gave Ordorica the idea to write the Alaskan Retreater’s Notebook, an epic memoir about one man’s journey into the Alaskan wilderness. With his wisdom, you will learn how to live with the country, and not against it.
Efficient energy management and effective conservation procedures have been very important considerations for our society for many years. An oil embargo in the 1970s and early 1980s brought about a new awareness of energy conservation. Because of various factors like loss of tax credits and efficiency standards imposed by the government, public interest dropped considerably in regard to energy conservation. A revival in energy conservation among the general public occurred following the Persian Gulf War in the early 1990s. What does the 21st century hold? Conflicts in the Middle East, high prices for petroleum, and increasing population worldwide will all be significant influences on energy and its conservation. Considerable discussion of climate change, global warming, and increased concerns in regard to our electricity supply have provided motivation for building energy demand to be more flexible. Energy Management and Conservation, Fourth Edition, provides a very practical discussion of how energy can be managed and saved in most types of buildings. This edition not only updates the previous edition but adds updated content concerning energy cost reduction/going green to improve the environment. The authors of this book have written several books that use the systems approach. Through the use of the systems approach, the reader will be able to grasp how different parts of a building fit together to form a unit that uses energy efficiently. This text provides a thorough and practical discussion of the operation of systems that are found in most types of buildings. Each system is discussed with energy management and conservation in mind/going green to save money and improve the environment. There are many ways to manage a building to accomplish efficient energy conservation. Several of the chapters have checklists at the end to summarize ways of conserving energy that relate to the chapter. Important changes in this edition include coverage of governmental requirements from agencies such as Environmental Protection Agency (EPA), United States Department of Energy (USDOE), and American Society of Refrigerating, Heating and Air-Conditioning Engineering (ASHRAE), updated as of 2022 standards. Instrumentation updates include types of sensors and the concept of "smart" devices such as meters. Addition of computer building maintenance management systems and new updates for renewable energy resources are included. Enhancements to existing systems content (such as variable frequency drives for pumps) have been carefully added.
