Unconventional resources have drawn much attention over the past decades. Despite their great potential, economic hydrocarbon production from these resources is hampered by our poor understanding of reservoir geology and limited engineering technology. In recent years, considerable progress has been made in the study of unconventional reservoir geomechanics, due to the commercial development. Unconventional reservoir geomechanics encompasses the fields of structural geology, petroleum geology, rock mechanics, and petroleum engineering, and it aims to solve a wide range of mechanical problems which arose during the exploitation of unconventional resources. Moreover, recent advances in geomechanics-based geoengineering enable scientists to research different scales of unconventional oil and gas reservoir exploitation in laboratories.
The study of reservoir geomechanics is significant for guiding unconventional oil and gas exploration (e.g., stress field simulation, fault sealing evaluation, fracture activity prediction, etc.) and development (e.g., wellbore stability analysis, fracture propagation in hydraulic fracturing, casing damage prediction and protection, etc.). With the in-depth development of multidisciplinary intersections, reverse engineering, 3D printing technology, multi-physical field coupling theory, and other methods that have been introduced to reservoir geomechanics, a number of new research results and technologies have emerged. The purpose of this research topic is to describe new developments and to expound basic theories, technical methods, and field practices in unconventional reservoir geomechanics
This research topic will collect comprehensive review papers and research articles of any scientific work and fundamental study for “unconventional reservoir geomechanics”. It will cover topics of interest that include, but are not limited to, the following:
• Mechanical and fracture stratigraphy;
• Spatial-temporal evolution of the reservoir stress field;
• Experimental and numerical studies on rock mechanics at different scales;
• In situ stress and fault sealing;
• Wellbore stability, fault activity, and trajectory optimization;
• Reactive reservoir mechanics and problems associated with lost circulation;
• Horizontal drilling and multistage hydraulic fracturing;
• Geomechanical responses of unconventional reservoirs with depletion;
• In situ stress in deep and ultradeep reservoirs.
