With the continuous growth of the world's oil and gas demand, the strategic position of unconventional oil and gas resources has become increasingly important. At the same time, the research on the geomechanics of unconventional reservoirs has achieved rapid development and abundant technical achievements. Geomechanics of unconventional reservoirs is an emerging frontier interdisciplinary research direction, involving multiple disciplines such as structural geology, reservoir geology, and rock mechanics. It aims to solve various mechanical problems that occur during the entire life cycle of exploration and exploitation of unconventional resources. The research on reservoir geomechanics has important practical significance for guiding the exploration (such as stress field simulation, fault sealing evaluation, prediction of fracture effectiveness and activity, etc.) and development (such as well trajectory optimization, hydraulic fracture propagation, drilling and completion methods, etc.) of unconventional oil and gas.

      In order to timely showcase the scientific research progress in the field of "geomechanics of unconventional reservoirs" at home and abroad and the latest related trends, and to provide diversified knowledge services for research in the field of earth sciences, the journal "Advances in Earth Science" specially launches a special column on "geomechanics of unconventional reservoirs". Professor Liu Jingshou, Professor Ding Wenlong, and Associate Researcher He Jianhua will jointly serve as the chief editors of this special column. It is planned to be published (in the regular issue) in the first half of 2024.

I. Scope of Contributions for the Special Column (including but not limited to)

1. Temporal and spatial evolution of the reservoir stress field;
2. Experimental and numerical simulation studies of rock mechanics at different scales;
3. In-situ stress and fault sealing;
