Advances in Geo-Energy Research (ISSN: 2207-9963; eISSN: 2208-598X; CODEN: AGRDC4) aims to publish high quality papers rapidly in the fields of natural geo-energy (oil, gas, coal geothermal, and gas hydrate), and focuses on combining theoretical, numerical and experimental approaches to the fundamental scientific advances in geo-energy systems. Advances in Geo-Energy Research is an interdisciplinary and international periodical devoted to promoting the interaction and multidisciplinary collaboration among scientific groups from different countries and regions, and both industry and academia. The scope of AGER is to provide an academic medium to researchers who are actively involved in one or more of the fields of geo-energy systems. Advances in Geo-Energy Research is a monthly open-access journal and free to read for all. It accepts original research articles, reviews, and rapid communications in the following domains of engineering, science and technology (but not limited to): (1) Geo-energy exploration, development and production (2) Heat and mass transfer in underground reservoirs (3) Unconventional oil and gas geology and engineering integration (4) New methods and techniques enhancing geo-energy recovery (5) Major theoretical progress and case studies of geo-energy
