This coring operations reference handbook is intended as a practical guide for the logging geologist to procedures, activities, and responsibilities required when bottomhole or sidewall coring is performed at the wellsite. Not all of the operations described are common practice in all logging units; however, familiarity with them is a necessary part of general ex ploration knowledge and professionalism. Chapter 1 discusses the concepts of porosity, permeability, and saturation, how these properties are determined in core analysis, and their significance in controlling rest:rvoir performance. Chapter 2 deals with the various techniques used in coring. Chapter 3 ex plains the routine role of the logging geologist in core retrieval, sampling, and qualitative evaluation. Chapter 4 details operating procedures for quantitative wellsite core analysis equipment. 1 INTRODUCTION 1. 1 GENERAL 1. 2 QUANTITATIVE CORE ANALYSIS The primary purpose of coring is to obtain rock samples of a sufficient size to obtain estimates of critical reservoir properties.

This book is a practical guide to downhole rock sampling and coring concepts, methods, systems, and procedures for practitioners and researchers. Its chapters are based upon years of extensive studies and research about the coring methods and via direct and continuous communication and consultation obtained from various service and operator companies such as Baker Hughes GE, NOV, OMV, and Sandvik. The contributors discuss the state-of-the-art coring methods and systems (mainly used in the petroleum industry), which include: · conventional coring; · wireline continuous coring; · invasion mitigation coring (low invasion, gel coring, sponge coring); · jam-detection, anti-jamming, full closure; · safe-coring and tripping; · oriented-coring; · pressure/in-situ coring; · logging-while-coring; · motor coring; · mini-coring; · coiled Tubing Coring; and · underbalanced coring. The contributors provide practical and applicable understanding of the procedures of these coring methods and systems, as well as the specific core barrel components, working mechanisms, and schematics of the tools and processes used. Because Coring Methods and Systems analyses and compares the core barrels used in both petroleum and mining industries, it enhances the communication and may allow knowledge transfer between the two industries. As core damage is a serious issue during coring and handling jeopardizing correct calibration of exploration data, Coring Methods and Systems has greatly focused on its identification and its mitigation. Therefore, it can be used as an ideal source for geologists, core analysts, and reservoir engineers, to ensure the retrieval of high-quality cores.

Störfälle in technischen Anlagen sind Zufallsereignisse; deshalb kann man sie nicht gänzlich vermeiden. Wohl aber lassen sich die Wahrscheinlichkeit ihres Auftretens und das Schadensausmaß verringern. Im Buch werden ausgehend von Gefährdungen durch Stoffe und Betriebsbedingungen mögliche technische und organisatorische Maßnahmen aufgezeigt, Gefährdungen zu mindern. Qualitative Analysemethoden zum Auffinden von Schwachstellen und zur Erhöhung der Sicherheit sowie Modelle zur Abschätzung von Störfallfolgen werden dargestellt. Die quantitative Bewertung der Wirksamkeit von Maßnahmen zur Verbesserung von Anlagentechnik und Sicherheit wird erläutert. Dabei spielen Unsicherheiten eine Rolle; sie folgen aus dem Zufallscharakter des Störfalls und aus Kenntnislücken bei einigen der zu behandelnden Phänomene. Der Leser wird mit Methoden der Störfallsimulation sowie Sicherheits- und Risikoanalysen vertraut gemacht und lernt, Möglichkeiten und Grenzen mathematischer Modellierung einzuschätzen. Als Grundlage sicherheitsrelevanter Entscheidungen wird die Risikoermittlung u.a. auf die Beurteilung der „funktionalen Sicherheit“ und die Bestimmung „angemessener Abstände“ zwischen Industrie und Bebauung angewandt. Zahlreiche ausgearbeitete Beispiele und Fallstudien realer Anlagen und Situationen vertiefen die Inhalte und erleichtern das Selbststudium.
