Modeling Approach to Mechanical Gas Dewatering of Filter Cakes With Non‐Uniform Cake Height

Chemical Engineering &Technology, Volume 48, Issue 1, January 2025.
This study explores how non‐uniform cake heights affect gas dewatering of filter cakes. By applying conservation laws and pre‐measured capillary pressure and relative permeability functions, predictions align well with experimental data. Abstract Gas dewatering of filter cakes with non‐uniform cake height is investigated.

Investigating Enhanced Oil Recovery Techniques in Ultratight Reservoirs Through Coreflooding Experiments

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
This study explores the efficacy of various enhanced oil recovery (EOR) techniques, including water alternating gas (WAG), gas alternating water (GAW), alkaline surfactant polymer (ASP), and chemical WAG (CWAG) injections. Through coreflooding tests and analysis, we assess their effectiveness in mobilizing and displacing trapped oil in reservoirs.

Experimental Study of Imbibition Characteristics During the Soaking Stage After Fracturing in Tight Reservoirs

Energy Science &Engineering, Volume 12, Issue 12, Page 5418-5428, December 2024.
ABSTRACT The soaking stage is vital for oil production after fracturing in tight reservoirs. However, the roles and contributions of spontaneous imbibition (SI) and forced displacement imbibition (FDI) during this stage are poorly understood. This study gave an in‐depth insight on the imbibition characteristics during the soaking stage under non‐zero ...

Boosting Barlow Twins Reduced Order Modeling for Machine Learning‐Based Surrogate Models in Multiphase Flow Problems

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract We present an innovative approach called boosting Barlow Twins reduced order modeling (BBT‐ROM) to enhance the reliability of machine learning surrogate models for multiphase flow problems. BBT‐ROM builds upon Barlow Twins reduced order modeling that leverages self‐supervised learning to effectively handle linear and nonlinear manifolds by ...

Community responses of arbuscular mycorrhiza fungi to hydrological gradients in a riparian Phragmites australis wetland

Ecology and Evolution, Volume 14, Issue 4, April 2024.
AM fungal community in rhizosphere soils of Phragmites australis exhibited obvious variation under different hydrological gradients. AM fungal community in Phragmites australis roots were not significantly affected by water regime. Abstract The hydrological regime is considered to be the major factor that affects the distribution of arbuscular ...
