“…KCl as an inorganic salt inhibitor, its inhibition effect is not very satisfactory, and the inhibition of shale often requires high concentration, and high concentration of potassium ions will also cause serious environmental pollution and drill bit corrosion. 15,16 For polyamine shale inhibitors, the large molecular polyamine molecular chain can be adsorbed on the surface of multiple sodium-based bentonite(Na-MMT) grains at the same time, and inhibit the expansion of the crystal layer through the bridging effect. At the same time (such as polyether diamine, amine-terminated polyamide, etc.)…”

When oil and gas extraction is drilled into water‐sensitive shale formations, water intrusion leads to hydration expansion and dispersion of shale clay minerals, which in turn leads to well wall instability. Two nanomaterials, PET and PEF, were synthesized using Hyperbranched polyethyleneimine (HPEI) as shell‐coated metal oxide nanoparticles (MONPs), and the nanomaterials were characterized in terms of molecular structure, thermal stability, and particle size distribution. The blocking and inhibition properties of PET and PEF were tested and investigated by analytical methods such as linear swelling experiments, shale rock chip rolling recovery experiments, and American Petroleum Institute (API) filtration loss experiments, the effects of PET and PEF on the rheology and filter loss reduction of water‐based drilling fuilds (WBDFs) were also investigated. PET and PEF have good blocking and inhibition properties, which somewhat ameliorate the effect of NPs on the rheology of WBDFs, while significantly improving the stability of shale in WBDFs.

“…As one of the world’s major energy sources, oil is important for modern industrial development. With the increasing demand for energy and the development of oil drilling technology, deep and ultradeep wells have become important directions for drilling development. − In the process of developing deep well oil and gas resources, wellbore instability is a common drilling accident problem in deep well drilling operations, which has seriously affected the exploration process of oilfield resources. , During the drilling process, shale inhibitors, filtration agents, and other additives are usually added to drilling fluids to prevent drilling safety accidents such as collapse, sticking, leakage, and blowout. − …”

At present, animal bone glue (BG) is being widely used in many fields, but there are no studies reported on oilfield chemistry. In this paper, an environmental water-based drilling fluids additive named bromoethane-modified bone glue (BG) was developed by using bovine bone glue and bromoethane as raw materials, anhydrous ethanol as solvent, sodium hydroxide as alkaline hydrolysis agent, and sodium carbonate as a system pH regulator. The inhibition, filtration performance, and temperature resistance of BG were evaluated. Performance study results show that the linear swelling rate of sodium bentonite (Na-MMT) was decreased from 50.2% (in tap water) to 38.2% (in 4 wt % BG solutions), and filtration loss was reduced from 30 mL (in tap water) to 12 mL (in 5 wt % BG). Hot-rolling experiments show that the BG solution still exhibits good performance even after 16 h × 130 °C. The reasons for BG to achieve excellent performance were analyzed through scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), ζ potential, thermogravimetric analysis (TGA), and microstructure. The results of SEM and FT-IR show that BG can fully dissolve in water and adsorb on the surface of clay particles by relying on its own adsorption functional groups such as −OH and −COOH. When 4% BG was added, ζ potential analysis revealed that the clay particle size declined by 0.502 μm, which indicated that BG can inhibit clay hydration swelling dispersion.

Drilling through shale formations can be expensive and time-consuming due to the instability of the wellbore. Further, there is a need to develop inhibitors that are environmentally friendly. Our study discovered a cost-effective solution to this problem using Gum Arabic (ArG). We evaluated the inhibition potential of an ArG clay swelling inhibitor and fluid loss controller in water-based mud (WBM) by conducting a linear swelling test, capillary suction timer test, and zeta potential, fluid loss, and rheology tests. Our results displayed a significant reduction in linear swelling of bentonite clay (Na-Ben) by up to 36.1% at a concentration of 1.0 wt. % ArG. The capillary suction timer (CST) showed that capillary suction time also increased with the increase in the concentration of ArG, which indicates the fluid-loss-controlling potential of ArG. Adding ArG to the drilling mud prominently decreased fluid loss by up to 50%. Further, ArG reduced the shear stresses of the base mud, showing its inhibition and friction-reducing effect. These findings suggest that ArG is a strong candidate for an alternate green swelling inhibitor and fluid loss controller in WBM. Introducing this new green additive could significantly reduce non-productive time and costs associated with wellbore instability while drilling. Further, a dynamic linear swelling model, based on machine learning (ML), was created to forecast the linear swelling capacity of clay samples treated with ArG. The ML model proposed demonstrates exceptional accuracy (R2 score = 0.998 on testing) in predicting the swelling properties of ArG in drilling mud.
