Using nanotechnology to prevent fines migration while production
Petroleum, 2021 Formation damage due to fines migration is a major reason for well productivity decline for oil and gas wells. Formation fines are small enough to pass through pore throats causing pore plugging and permeability decline.

Enhancing chalk formation integrity by diammonium phosphate treatment [PDF]
Scientific ReportsFine-grained chalk reservoirs in the North Sea (NS) commonly experience fines migration or particle production, or both, leading to production issues like formation damage and reduced production.

Analysis of characteristics of coal fine production and its influence factors in Baode block [PDF]
Youqicang pingjia yu kaifa, 2023 The issue of coal fine production is increasingly prominent in the development of coal-bed methane. Implementing appropriate measures to control the migration and production of coal fines is crucial for achieving stable and high production of coal-bed ...

Experimental and theoretical investigation on low salinity brine injection timing in high water cut reservoirs for residual oil reduction and improved oil recovery [PDF]
Journal of Chemistry Letters, 2021 In this research, low salinity water flooding was used to investigate its low salinity effect in a high water cut sandstone reservoir to improve oil recovery. The application was done to five different sandstone cores in high water cut levels of 70%, 75%,

Effect of fines migration on oil recovery from carbonate rocks
Advances in Geo-Energy Research, 2023 : We perform single-phase and two-phase flooding on Edwards Brown rock samples. The single-phase injection was of seawater or CaCl 2 brine, at successive salinities 0.63, 0.21, 0.07, 0.05, and 0 mol/L (distilled water). For CaCl 2 brine experimental run,

Journal of Petroleum Exploration and Production Technology, 2022 Re-injection of carbon dioxide (CO2) in deep saline formation is a promising approach to allow high CO2 gas fields to be developed in the Southeast Asia region. However, the solubility between CO2 and formation water could cause injectivity problems such

Numerical simulation study on influence of coal fines migration on porosity and permeability in cataclastic coal [PDF]
Youqicang pingjia yu kaifaDuring coalbed methane (CBM) production, coal fines within the reservoir can migrate, potentially blocking pore throats and resulting in a significant reduction in reservoir permeability. This process adversely affects the final CBM yield. To investigate

Deadlock-free fine-grained thread migration [PDF]
Proceedings of the Fifth ACM/IEEE International Symposium on Networks-on-Chip, 2011 Several recent studies have proposed fine-grained, hardware-level thread migration in multicores as a solution to power, reliability, and memory coherence problems. The need for fast thread migration has been well documented, however, a fast, deadlock-free migration protocol is sorely lacking: existing solutions either deadlock or are too slow and ...
