Damage of Green Synthetic Cement Slurry to Clastic Rock Reservoir by Meng Xu, Xin Tan, Libo Yang, Hanlie Cheng, David Cofell

“…The research results show that the average porosity of the clastic rock reservoir in the study area is 15%, the permeability is high, the average pore size of the reservoir is between 37 and 56 μm, the microfractures are developed in the reservoir section, and the porosity and permeability conditions are good; high-valent cations and inorganic ions in the filtrate generate inorganic scales such as CaCO3 and Mg(OH)2 and cross-link with dissolved polymers to form flocculation substances, which cause the filtrate to damage the reservoir, and at the same time, the cement particles in the pore throats in the near wellbore zone are lost along with the leakage. …”

Three-dimensional mapping of the altermagnetic spin splitting in CrSb by Guowei Yang, Zhanghuan Li, Sai Yang, Jiyuan Li, Hao Zheng, Weifan Zhu, Ze Pan, Yifu Xu, Saizheng Cao, Wenxuan Zhao, Anupam Jana, Jiawen Zhang, Mao Ye, Yu Song, Lun-Hui Hu, Lexian Yang, Jun Fujii, Ivana Vobornik, Ming Shi, Huiqiu Yuan, Yongjun Zhang, Yuanfeng Xu, Yang Liu

“…Tight-binding model analysis indicates that the large altermagnetic splitting arises from strong third-nearest-neighbor hopping mediated by Sb ions. The large band/spin splitting near Fermi level in metallic CrSb, together with its high T N (up to 705 K) and simple spin configuration, paves the way for exploring emergent phenomena and spintronic applications based on altermagnets.…”
