Special Issue Information

Dear Colleagues,

The trajectory of industrialization is tightly correlated with geo-energy. Academics place a high value on all kinds of cutting-edge studies. Every breakthrough, whether theoretical or in engineering, has the potential to significantly advance society. This Special Issue seeks frontier and innovative research on the low-energy development of geo-energy resources. Several research studies are presently being conducted on EOR flooding materials, such as polymer, CO2, air, steam and composite methods. Additionally, the study of some low-energy and promising heating reservoir technologies, such as nuclear energy, solar energy, in situ upgrading, and electromagnetic heating, has also gradually increased. Of course, with the continuous innovations in computer and information technology, numerical simulation technology and big data analysis methods also play pivotal roles in the development of high-efficiency and low-energy geological energy.

This Special Issue aims to present and disseminate the most recent advances related to the newest advances in low-energy processes for geo-energy development.

Topics of interest for publication include, but are not limited to, the following:

  • Intelligent well technologies;
  • New technologies in ROP improvement;
  • New technologies in cold production;
  • New technologies in waterflooding for geo-energy resource development;
  • New technologies in polymer flooding;
  • New technologies in emulsion flooding;
  • New technologies in enhanced CO2 injection;
  • New technologies in enhanced air injection;
  • New technologies in enhanced steam injection;
  • New technologies in heating geo-energy reservoirs;
  • New technologies in geo-energy reservoir simulation;
  • Low-energy processes for shale oil recovery;
  • Low-energy processes for tight oil recovery.

Process Optimization of Amphiphobic Surfactant Treatments for Mitigating Water-Lock Damage in Shale Gas Reservoirs

Water blockage severely restricts gas transport in deep shale reservoirs, while effective mitigation requires a precise balance of multiple operational variables. This study utilizes core-flooding experiments to optimize the treatment processes of an amphiphobic fluorinated copolymer, focusing on the coupled roles of surfactant concentration, injected volume, and shut-in duration. The results show that permeability damage decreases rapidly with surfactant concentration, optimizing at 0.5 wt.%. Conversely, excessive liquid retention beyond a critical injection threshold of 1.0 PV triggers secondary water-blocking. Extending the shut-in duration to 8 days facilitates surfactant redistribution and interfacial equilibrium, gradually reversing rock wettability to a stable amphiphobic state. Crucially, the concurrent reduction in interfacial tension markedly lowers capillary resistance, allowing trapped water to detach and flow back under significantly lower driving pressures. This optimization effectively minimizes the energetic barrier for fluid displacement and creates a gas-preferential flow environment. The proposed laboratory operational window balances surfactant dosage, injection volume, and shut-in duration under the tested conditions, providing an experimental reference for optimizing post-fracturing cleanup, controlling liquid retention, and improving early-time gas flowback in shale gas reservoirs.

To address the issue of CO2 leakage induced by microcracks in cement sheaths during geological CO2 storage, this study developed a multi-crosslinked CO2-responsive preformed particle gel (MCCR-PPG) system. Using vinyl silica nanoparticles (VSNPs) as nano-crosslinkers and reinforcing agents, combined with CO2-responsive monomers, sodium alginate, organic crosslinkers, and ionic crosslinkers, an intelligent plugging material with a quadruple crosslinking network was constructed. The optimal formulation was determined through single-factor experiments: the molar ratio of DMAA, VIM, and NVP was 2:2:1; the dosages of crosslinker MBA and initiator APS were each 0.5% of the total monomer molar amount; the concentration of CaCl2 solution was 0.1 mol/L; and the VSNP content was 1 wt%. The results showed that the equilibrium swelling ratio of MCCR-PPGs in CO2 acidic solution reached 3200%, which was 4.27 times that in deionized water, demonstrating excellent CO2 responsiveness. Fracture plugging experiments further confirmed that the swollen gel formed a stable barrier within fractures, effectively preventing CO2 channeling with a breakthrough pressure differential of 2.008 MPa, indicating excellent plugging performance. This study provides a critical material solution for wellbore integrity in CCUS applications and holds significant engineering value for preventing CO2 leakage and ensuring storage safety.
