The SpringerBriefs series in Petroleum Geoscience & Engineering promotes and expedites the dissemination of substantive new research results, state-of-the-art subject reviews and tutorial overviews in the field of petroleum exploration, petroleum engineering and production technology. The subject focus is on upstream exploration and production, subsurface geoscience and engineering. These concise summaries (50-125 pages) will include cutting-edge research, analytical methods, advanced modelling techniques and practical applications. Coverage will extend to all theoretical and applied aspects of the field, including traditional drilling, shale-gas fracking, deepwater sedimentology, seismic exploration, pore-flow modelling and petroleum economics. Topics include but are not limited to:
Petroleum Geology & Geophysics
Exploration: Conventional and Unconventional
Seismic Interpretation
Formation Evaluation (well logging)
Drilling and Completion
Hydraulic Fracturing
Geomechanics
Reservoir Simulation and Modelling
Flow in Porous Media: from nano- to field-scale
Reservoir Engineering
Production Engineering
Well Engineering; Design, Decommissioning and Abandonment
Petroleum Systems; Instrumentation and Control
Flow Assurance, Mineral Scale & Hydrates
Reservoir and Well Intervention
Reservoir Stimulation
Oilfield Chemistry
Risk and Uncertainty
Petroleum Economics and Energy Policy

1.1 Introduction to Unconventional Reservoirs
Unconventional resources or unconventional reservoirs (UR) refer to a category of underground hydrocarbon deposits which are different in operations and methods of recovery compared to conventional reservoirs. As a matter of fact, such discrepancies originate from their special geological, geochemical, and petrophysical characteristics. The most important feature of URs is their low-permeability nature. Also, some storage and flow mechanisms of these reservoirs are not common in conventional oil and gas deposits. Thus, it can be expected that URs require special studies in order to enhance their efficiency along with an economical production.
