Special Issue Information

Dear Colleagues,

Gas capture, separation and storage play critical roles in energy utilization efficiency, a key issue that must be addressed in traditional petrochemistry and emerging industries aiming at net-zero CO2 emission. The development of industry and technology has brought higher requirements and challenges to gas capture, separation and storage materials and technologies.

The Belt and Road Initiative proposed by China is a common aspiration of all countries along their routes to achieve sustainable development of the environment, economy, society, and people's livelihood. To mitigate global warming and carbon emissions and reach carbon neutrality, CO2 capture and geological storage, hydrogen production, transport and storage project and hydrocarbon/coal recovery must be realized. The development of nanomaterials with desired combination properties and corresponding methods for target applications, which can minimize the environmental impact by gas capture, separation and storage, has attracted increasing attention over the last few decades. Green and eco-friendly techniques focus on the relevant mechanisms and technology, which reduce the use of hazardous substances and non-renewable sources. Nanomaterials for gas capture, separation and storage are considered to be energy efficient, low cost, renewable, and environmentally friendly for a sustainable future.

This Special Issue shall present the latest research updates related to CO2 capture, utilization and storage (CCUS), petrophysics, geology and other areas. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • CO2/CH4/H2 geo-storage;
  • Gas transport in nanoporous media;
  • Advanced nanomaterials for gas capture, separation and storage;
  • Mechanisms of gas capture, separation and storage.

We look forward to receiving your contributions.

Conventional coalbed methane (CBM) reservoir models for injection fall-off testing often disregard the quadratic pressure gradient’s impact. This omission leads to discrepancies in simulating the transient behavior of formation fluids and extracting critical reservoir properties. Accurate determination of permeability, storability, and other properties is crucial for effective reservoir characterization and production forecasting. Inaccurate estimations can lead to suboptimal well placement, ineffective production strategies, and ultimately, missed economic opportunities. To address this shortcoming, we present a novel analytical model that explicitly incorporates the complexities of the quadratic pressure gradient and dual-permeability flow mechanisms, prevalent in many CBM formations where nanopores are rich, presenting a kind of natural nanomaterial. This model offers significant advantages over traditional approaches. By leveraging variable substitution, it facilitates the derivation of analytical solutions in the Laplace domain, subsequently converted to real-space solutions for practical application. These solutions empower reservoir engineers to generate novel type curves, a valuable tool for analyzing wellbore pressure responses during injection fall-off tests. By identifying distinct flow regimes within the reservoir based on these type curves, engineers gain valuable insights into the dynamic behavior of formation fluids. This model goes beyond traditional approaches by investigating the influence of the quadratic pressure gradient coefficient, inter-porosity flow coefficient, and storability ratio on the pressure response. A quantitative comparison with traditional models further elucidates the key discrepancies caused by neglecting the quadratic pressure gradient. The results demonstrate the proposed model’s ability to accurately depict the non-linear flow behavior observed in CBM wells. This translates to more reliable pressure and pressure derivative curves that account for the impact of the quadratic pressure gradient. Full article
