Hello Everyone and thank you for joining us weekly during our live Wed(NSI)days! Next week, we're excited to welcome Frank Zamora, Senior Vice President, Operations at Premier Corex who will be sharing a presentation on: Hypothesis on the formation of Gummy Bears aka Shmoo, Goo… Polyacrylamide is widely used in hydraulic fracturing due to its properties as a viscosity enhancer and friction reducer. This presentation aims to evaluate polyacrylamide flowback through a combination of solubility tests, Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) techniques. The solubility test assesses the degree of degradation and recovery of PAM by observing its dissolution in various solvents. Variations in solubility reflect changes in the polymer's chemical structure. FTIR analysis is employed to detect changes in the chemical structure of PAM by identifying characteristic functional groups before and after flowback. XRD is used to investigate the crystalline structure of residual minerals or additives in the flowback fluid that may interact with PAM. This characterization allows for the assessment of possible contamination or changes in the polymer's crystallinity, which could impact its performance and flowback efficiency. By integrating these methods, this presentation provides a comprehensive understanding of the degradation behavior, structural changes, and potential contaminants affecting polyacrylamide flowback. The findings contribute to the optimization of flowback treatment and PAM recovery strategies, ultimately enhancing the sustainability and efficiency of hydraulic fracturing operations. Join us for this insightful presentation and to participate in an engaging discussion!

We are pleased to announce the release of our new study on "Subsurface Hydrogen Storage in Limestone Rocks: Evaluation of Geochemical Reactions and Gas Generation Potential" #Authors: Ahmed Al-Yaseri*, Ahmed Fatah, Ph.D √, Bidoor AlSaif, Sivabalan Sakthivel*, Abduljamiu Amao from King Fahd University of Petroleum & Minerals - KFUPM. Abdulaziz S. Al-Qasim, and Ali A. Yousef from aramco. #The article is available online at: https://lnkd.in/d56vQAQu #Abstract Underground hydrogen storage (UHS) in carbonate reservoirs is a suitable solution for safe storage and efficient hydrogen recovery during the cycling process. The uncertainties associated with potential geochemical reactions between hydrogen, rock, and brine may impact the long-term containment of produced hydrogen in carbonate formations. Despite the current interest in studying hydrogen-rock reactions, only limited work is available in the literature. In this study, we experimentally evaluate the reactivity of carbonate rocks to hydrogen and address the potential of gas generation induced by geochemical reactions. Limestone samples are treated with hydrogen under 1500 psi and 75 °C temperature for a duration between 6 and 13 months using simple reaction cells. Scanning electron microscopy (SEM) analysis is performed to examine the potential dissolution/precipitation reactions induced by hydrogen. In contrast, gas chromatography (GC analyzer) analysis and inductively coupled plasma optical emission spectroscopy (ICP-OES) are conducted to detect gas generation and ion precipitation. The experimental results indicate no significant impact of hydrogen treatment on surface morphology and pore structure even after 6 months of treatment, suggesting that abiotic reactions in carbonate rocks are unlikely to occur during the first stages of UHS. Furthermore, in the presence of brine, there are no apparent indications of geochemical reactions occurring between hydrogen and calcite, and no traces of any other gases are detected after 13 months of treatment. Besides, the solutions’ pH remains almost unchanged, with a minor increase in calcium (Ca2+) ions in the solution, which is attributed to the presence of water, not hydrogen reactions. The results of this work promisingly support the utilization of carbonate reservoirs for long-term hydrogen storage.

News Release: Lomiko Announces Excellent Results from La Loutre Graphite Testing with CRITM Grant and Corporate Update Belinda Labatte, CFA, MBA, ICD.D, CEO and Interim Chair of the Board stated: “Lomiko has now re-confirmed the suitability for the La Loutre graphite for battery anode material at the NRC lab with a comprehensive mandate that will now continue into Phase 2. In this phase, using thermal purification methods and a larger sample size, the electrochemical performance results surpassed the study results from the Polaris tests announced on April 1, 2024. Lomiko has now demonstrated that the La Loutre natural flake graphite performs well using all three standard purification methods: thermal, prepared and tested by the NRC, and alkaline and acid-based (prepared by ProGraphite and Corem), as tested by Polaris LLC.” https://lnkd.in/gVRY4Xwz #graphite #criticalminerals #electricfuture #EVrevolution #miningmatters #miningnews #MiningQuebec

Rainbow Rare Earths said a seventy-day pilot test for the Phalaborwa development project in South Africa had confirmed concentrate recoveries at 66%. A final separation stage pilot plant will further sort the concentrate into rare earth oxides, with this work ongoing in Florida. The separation of two key metals has now reached over 95% purity via an optimised first-stage chromatography step, with the process expected to reach the targeted purity of 99.5% Other key findings from the pilot were a  50% reduction in the expected heating energy requirement while the first-stage impurity leach worked to the desired level.  As a result, the subsequent rare earths leach has been reduced from three stages in the PEA to two stages, while a continuous ion exchange ("CIX") pilot plant operation was conducted at Mintek to recover the rare earths in the impurity leach solution.

The results speak for themselves: ARi delivers the only fully scalable DLE platform that delivers peak performance. #DLE #directlithiumextraction #adsorption #lithium

A really nice review on the technical challenges and financial opportunities associated with #lithium extraction from produced water. I imagine that this will be a prominent topic for discussion at some of the forthcoming #water and #energy conferences Produced Water Society Oilfield Water Management Symposium Permian Basin Water In Energy Conference. Let's keep in mind that precious metals and #REEs represent only a portion of the extractable value that is present in these brines. The team at Infinity Water Solutions and I are excited about extracting all of the goodies. https://lnkd.in/g8yGVwVW
