A new environmentally friendly water-based drilling fluids with laponite nanoparticles and polysaccharide/polypeptide derivatives

Study on the Dispersion Stability and Plugging Performance of Dopamine-Modified Multiwalled Carbon Nanotubes

“…However, OBDFs are costly and not environmentally friendly. 3 Under the double pressure of economic benefits and environmental protection, high-performance, environmentally friendly water-based drilling fluids (WBDFs) and additives have become one of the important directions for the development of the drilling fluid industry. 4 However, compared with OBDFs, WBDFs are prone to intrude into the formation along fractures.…”

“…These fluids have strong inhibition and good lubrication performance and cause less damage to oil and gas formations. However, OBDFs are costly and not environmentally friendly . Under the double pressure of economic benefits and environmental protection, high-performance, environmentally friendly water-based drilling fluids (WBDFs) and additives have become one of the important directions for the development of the drilling fluid industry .…”

Molecular simulation of the rheological properties and shear thinning principles of supramolecular drilling fluids at different burial depths

“… 13 Li et al designed new environmentally friendly water-based drilling fluids by adding LAPONITE® nanoparticles and polysaccharide/polypeptide derivatives. 14 In recent years, some scholars have proposed developing supramolecular drilling fluids with special rheological properties by supramolecular chemistry-related theories, which can significantly improve the shear dilution and pollution resistance of drilling fluids and the efficiency of injection drilling. 15,16 Supramolecular chemistry explores the interaction between two or more molecular chains via intermolecular forces to form supramolecular systems with specific structures and functions, including structures and functions of entities formed by the joining of two or more chemical species.…”

Electrochemical Determination of Epinephrine in Pharmaceutical Preparation Using Laponite Clay-Modified Graphene Inkjet-Printed Electrode

“…Clay minerals can be used to increase the local analyte concentration on various solid electrodes due to their ordered structure formed mainly by aluminum phyllosilicate polyhedra organized in a two-dimensional stable network with intercalation ability to entrap certain guest molecules [ 18 ]. Laponite (La), for instance, is a synthetic clay mineral with a structure and composition close to that of the natural clay mineral hectorite [ 19 ]. Its disk-like shape has a thickness of 0.92 nm, an exchange capacity of 50–55 mmol/100 g and an average diameter of 25 nm, with a surface area of up to 370 m 2 ·g −1 .…”
