This dictionary covers terms related to oil and gas drilling and drilling and recovery techniques. Care has been taken to incorporate terms and expressions used, by gathering information from reliable scientific and technical documents such as manuals, guides, brochures, specialized glossaries and diagrams. The fact that different companies and manufacturers use varying terms to describe similar objects or operations has not been overlooked.

Special attention has been devoted to important areas such as geology, drilling methods and equipment, logging, sampling, well servicing, mud engineering, offshore and permafrost conditions and preparation for shipping and monitoring; the dictionary therefore facilitates communication between those involved directly and indirectly with the development and management of energy resources. Oil companies, engineers, equipment manufacturers, students, translators and interpreters, and all those involved in the field of energy production will find this dictionary an invaluable reference tool.
