“…Simultaneously, the cationic in formation water will penetrate into the annulus cement slurry in the period of waiting on cement (WOC), especially for the cementation in high salinity wells in oil field. The traditional copolymer used as fluid loss agent usually shows a curly state in ionic liquids, which will affect the fluid loss controlling performance of polymer and cementing quality . Therefore, it is necessary to evaluate the salt‐tolerance of the zwitterionic copolymer.…”

The present investigation deals with the problems of unsatisfactory high-temperature resistance, inferior salt tolerance and poor comprehensive performance for the domestic fluid loss additives. In this study, a zwitterionic polymer, 2-acrylamido-2-methylpropanesulfonic acid/diallyldimethylammonium chloride/N,N-dimethylacryl amide/ acrylic acid used as fluid loss agent for oil well cementing, was synthesized by free radical polymerization in aqueous solution with ammonium persulfate and N,N,N 0 ,N 0 -tetramethylethylenediamine as initiator. The optimal synthesis conditions were obtained via singlefactor variable analysis. The compositions, microstructural morphologies, and thermal-stability of polymer were characterized by FT-IR, 1 H NMR, SEM, DTG, and DSC techniques. The results manifested that the synthetic polymer cement slurry exhibited prominent advantages such as excellent fluid loss control capacity, thermal stability (up to 2008C), salt-tolerance (saturated brine) and rheological behavior. Even more strikingly, the zwitterionic polymer showed less impact on hardening cement and accelerated the post compressive strength of set cement, verified through the ultrasonic method. Additionally, the mechanism of fluid loss control was found to rely mainly on improving the filter cake quality and the polymer chemisorptions on the surface of hydrated cement through SEM, permeability and TOC analysis. In consequence, the zwitterionic polymer enhanced the comprehensive properties of cement slurry and had great potential to apply in high temperature and high salinity oil-well cementing. POLYM. ENG.

The Nubian sandstone aquifer's hydrogeophysical and natural radioactivity parameters at the Northwestern part of El Ain village, Sharq El Oweinat, Southwestern desert, Egypt are resolved using geophysical well logging and natural radioactivity techniques. The study aims to monitor the phenomenon of appearing an unusual high gamma-ray at a zone of high resistivity record. A nest of well logs is collected to assess how the phenomenon is widespread. Results of correlated well logs are clarified that this phenomenon at zone between 80 and 100 m and zone of 200 and 230m depth is noticed. The petro-physical properties are estimated from the recorded well logs. The results showed that the percentage of the average of effective porosity % varies between 20 and 28.2%, while average vary from 2 to 12.5 %, which indicates that the aquifer of Nubian Sandstone is classified as a clean aquifer. The natural radioactivities of the studied area in the rock samples were evaluated using high-purity germanium (HPGe) detector. The results indicated that the average value of Th-232 is (51.32 ±4.92%) Bq/kg, Ra-226 is (29.03 ± 4.68%) Bq/kg while the radioactivity concentration of K-40 exists only in one sample with low concentration.

“…Many techniques by destructive procedures such as ICP-AES, ICP-MS, Atomic Absorption, and UV, have been used to determine the elemental compositions in the solid samples [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Neutron activation analysis (NAA) stands out among the highly precise and sensitive analytical methods currently in use in that it does not require prior sample preparation, such as acid digestion, which greatly improves both precision and accuracy in determining the content of major and trace elements in rocks [3,30].…”

The current work was carried out to characterize rock samples of mudstone, sand, and limestone collected at different depths from Northwestern Coast, Ras El-Hekma -Egypt. The samples were subjected to neutron activation analysis to determine the elemental composition and to better understand the geochemistry of the rocks. The abundance of 17 elements was determined. Bivariate and multivariate statistical analyzes were performed to investigate the origin of rocks and common geochemical characteristics (i.e., type, origin, geological history, major and trace composition, weathering, and alteration). The normalized results obtained showed that the abundances of Ca and Sr were significant compared to the corresponding values in the literature. The enrichment factor (EF) was calculated to obtain more information about the sources of the increased abundances of the metals. The results obtained can provide baseline data for the surveyed region and can be utilized by the government, policymakers, and interested parties for future research and development endeavors and planning.
