Case Study from the Ordos Basin

• Format: ePub

Produktbeschreibung

Lacustrine Shale Gas: Case Study from the Ordos Basin examines the special sedimentation and formation environment based on the actual exploration of lacustrine shale gas. Using the Chang7 black shale of Yanchang formation in Ordos basin as an example, this book deeply dissects the Lacustrine shale geological characteristics and offers fresh insights into Lacustrine shale geochemistry, shale reservoir, hydrocarbon accumulation and resource evaluation. The book not only enriches, develops and contributes to new theories of shale gas exploration, but also contributes to a new research field, lacustrine shale gas exploration.

Shale gas is the mixed phase natural gas that includes adsorbed phase and free phase gas. It is accumulated in the rich organic matter in shale. In recent years, with great changes in global oil and gas exploration and energy supply situation, shale gas has attracted a lot of attention, becoming the focus of the energy industry.

• Reflects the development of world-leading shale gas exploration technology in China
• Analyzes first-hand experimental data and scientific research methods on the geological characteristics of lacustrine shale gas
• Systematically discusses the theory of lacustrine shale gas exploration, from source rock characteristics, shale reservoir characteristics, and shale gas accumulation, to shale gas resources evaluation
• Provides practical guidance by using the Ordos basin as example
