About the Journal

Aims and Scope

Improved Oil and Gas Recovery (IOGR) (Electronic ISSN: 2688-8246) is a fully open access, peer-reviewed international journal dedicated to advancing the science and engineering of maximizing hydrocarbon recovery from subsurface reservoirs. The journal serves as a comprehensive platform for disseminating high-quality original research, reviews, and technical notes across the entire spectrum of disciplines that contribute to improved oil and gas recovery.

Our scope encompasses, but is not limited to, the following key areas:

  • Petroleum Exploration — Basin analysis, petroleum system modeling, play assessment, geophysical prospecting, and seismic interpretation that inform recovery potential and reservoir characterization.
  • Petroleum Geology — Reservoir geology, sedimentology, structural geology, diagenesis, source rock evaluation, and geological modeling for reservoir description and recovery optimization.
  • Petroleum Physics — Petrophysics, rock physics, pore-scale transport phenomena, multiphase flow in porous media, interfacial phenomena, and physical simulation of recovery processes.
  • Petroleum Chemistry — Oilfield chemistry, chemical EOR (polymer, surfactant, alkaline flooding), nanofluid applications, gas injection chemistry, formation damage control, and produced fluid chemistry.
  • Drilling Engineering — Wellbore design, drilling fluids, directional/horizontal drilling, underbalanced drilling, well integrity, and drilling optimization for improved reservoir access and recovery.
  • Production Engineering — Well completion, stimulation (including hydraulic fracturing and matrix acidizing), artificial lift, production optimization, sand control, and flow assurance.
  • Reservoir Engineering — Reservoir characterization and modeling, reserve estimation, numerical simulation, enhanced oil recovery (EOR) processes (thermal, miscible/immiscible gas, chemical, and microbial), waterflooding optimization, and field development planning.

IOGR particularly encourages submissions that address interdisciplinary approaches, novel technologies, and field-scale applications aimed at improving ultimate recovery factors from both conventional and unconventional reservoirs, including tight oil/gas, shale, heavy oil, and coalbed methane. Studies bridging laboratory experimentation, theoretical analysis, and field implementation are given high priority.

By bringing together these interconnected disciplines within a single journal, IOGR aims to foster cross-disciplinary innovation and accelerate the transfer of fundamental understanding into practical recovery solutions that meet the world's evolving energy needs.
