Summary Most shale formations contain a large amount of expansile sodium montmorillonite (Na-Mnt), have high water adsorption, and experience hydration swelling, which causes an unstable wellbore wall resulting from formation shrinkage, sticking, balling, time-wasting, well collapse, and, in extreme cases, complex downhole accidents costs. Polyamines, like hexane-1,6-diamine (HEDA), are inhibitors shallow drilling. Inorganic organic K-salts can improve the inhibitory performance polyamine...
Summary Sodium bentonite (Na-bentonite) is one of the most used water-based drilling mud (WBDM) additives due to its unique features for better well integrity. As a hydrophilic clay mineral, it bound hydration expansion, altering fluid properties and causing wellbore instability. Small polyamine treatment agents are often avert minerals, which can minimize dangers reservoir damage Revealing their inhibition mechanisms vital evaluating designing inhibitor molecules by understanding molecular...
Over the last two decades, swelling properties of montmorillonite (MMT) have been studied in many experimental and simulation works, but less attention has given to MMT containing a mixture monovalent/monovalent monovalent/bivalent cations interlayer spaces. We carried out molecular dynamics patterns Na-, Mg-, Na/Cs-, Na/Mg-MMT an isobaric isothermal ensemble (NPT) at T = 300 K p 1 atm. The reproduced pattern curves obtained showed difference between hydration mechanisms type used this...
The comparative study between electrodes as cathode for electrochemical reduction of ammonia from artificial and real wastewater was carried out with Ti/Iro2 anode Cu, Fe Cu/Zn cathode. We studies effect different cathode, the presence absence NaCl temperature such 200C, 300C 400C on wastewater. It shown after 30min treatment under optimal condition which were current density 18.32mA/cm2, space electrode 1.1 cm, amount 0.5g/l COD concentration in municipal 185mg/l a removal 38% total NH3-N...
Abstract Na-bentonite is one of the most used water-based drilling mud additives due to its unique features for better well integrity. As a hydrophilic clay mineral, it bound hydration expansion altering fluids’ properties and causing instability. Small polyamine treatment agents are often avert minerals, which can minimize dangers reservoir damage wellbore Revealing their inhibition mechanisms vital evaluating designing inhibitor molecules by understanding molecular behaviour at sodium...
Abstract Most shale formations, contain a large amount of expansive sodium montmorillonite (Na-Mnt), have high water adsorption, and hydration swelling, causing unstable wellbore wall, resulting from formation shrinkage, sticking, balling, time-wasting, well collapse in extreme cases complex downhole accidents, costs. Polyamines like hexane-1, 6-diamine (HEDA), are inhibitors shallow drilling. Inorganic, organic K-salts can improve the inhibitory performance polyamine inhibitors. Molecular...
In the present study, we performed a molecular dynamics simulation of intercalation poly( N-isopropyl acrylamide) (NIPAM) 3 and N-vinyl caprolactam) (NVCL) trimers into Na-montmorillonite (Na-Mt) to evaluate their effects on interlayer structure stability hydrated Na-Mt. The impact both species properties at different temperatures in canonical ensemble (NVT) were investigated. results showed that electrostatic forces exerted by Na cations H 2 O molecules arrangement are not affected rise...
