Rock Fabric of Tight Sandstone and Its Influence on Irreducible Water Saturation in Eastern Ordos Basin

Mianmo Meng et al.

Summary: In this study, the irreducible water saturation and its controlling factors in the Upper Paleozoic Taiyuan and Shihezi Formations were investigated. The results showed that the saturation was related to porosity, permeability, average pore diameter, and specific surface area in both formations. Furthermore, the saturation can be further analyzed by dividing it into saturation controlled by small throat or capillary force. Overall, this study improves our understanding of the mechanism and controlling factors of water occurrence.

Rock Fabric of Lacustrine Shale and Its Influence on Residual Oil Distribution in the Upper Cretaceous Qingshankou Formation, Songliao Basin

Mianmo Meng et al.

Summary: This study focused on the rock fabric and residual oil distribution in the Upper Cretaceous Qingshankou Formation in the Songliao Basin. Various analysis methods were employed to determine the material composition and pore characteristics. The results showed that the organic matter was predominantly type I, with clay being the main mineral component. Nano-scale inorganic pores and micro-scale organic pores were found, with small pores containing a significant amount of residual oil. This study contributes to the understanding of rock fabric and its impact on residual oil distribution in lacustrine shale.

Insight into Water Occurrence and Pore Size Distribution by Nuclear Magnetic Resonance in Marine Shale Reservoirs, Southern China

Mianmo Meng et al.

Summary: This study investigates the water occurrence and pore size distribution in moderate-shallow and deep marine shales using various experimental methods. The results show that deep shales have abundant organic nanopores, while moderate-shallow shales have few organic pores. The high irreducible water saturation in both types of shales is attributed to the strong capillary force of the nanopores. The study provides insights into the characterization of water occurrence and pore size distribution in marine shales.

A Novel Method To Assess Stimulation of Sandstone Cores Damaged by Fines Migration

Ahmed Hanafy et al.

Summary: Sandstone stimulation faces challenges due to formation heterogeneity and clay mineral sensitivity to acids. Fine migration complicates well-stimulation and reduces productivity. This study aims to locate, quantify, and describe damage from fine migration in sandstone formations and evaluate the composition of clay content and its effects. CT scanning and NMR measurements were used to visualize and analyze pore structure changes. The technique successfully predicted changes in pore structure and enhanced permeability.

Application of a novel amphiphilic polymer for enhanced offshore heavy oil recovery: Mechanistic study and core displacement test

Xiao Wang et al.

Summary: A molecular modified polyacrylamide with Gemini surfactant monomers (HA1) was evaluated as an alternative for offshore heavy oil recovery. HA1 demonstrated advanced functions such as aqueous-phase viscosifying ability, significant interfacial activity, and reduction of heavy oil viscosity. Coreflooding experiments confirmed the increased oil recovery efficiency achieved by HA1 through improved microscopic efficiency and dispersion of asphaltene aggregates.

Displacement behavior and mechanism of long-term water flooding in sandstone oil reservoirs

Ren-yi Cao et al.

Summary: Experimental studies were conducted to investigate the effects of factors such as PV number, viscosity, and displacement rate during long-term water flooding (LTWF) on sandstone oil reservoirs. The research findings indicate that increased viscosity leads to decreased water phase permeability, increased residual oil saturation, and earlier increase in water content rate. Furthermore, higher water flooding rates result in higher ultimate recovery, and higher asphaltene content contributes to higher viscosity and more oil-wet reservoir conditions. Additionally, after LTWF, the wettability tends to become more water-wet, which is beneficial for heavy oil recovery.
