“…It is generally believed that the low hydration energy and small ionic radius of K + ensure its embedding into the clay. SIAT and Ultrahib are able to enter the tetrahedral layer and compress the diffuse electric double layer of shale due to their small volume [5,7,8].…”

“…In recent decades, various compounds, such as simple inorganic monomeric amines, have been successfully employed as shale inhibitors in WBDFs. However, the temporary and low level of shale inhibition has limited their widespread application [5][6][7]. To overcome the performance-related shortcomings, some copolymers such as HPAM (Hydrolyzed polyacrylamide), hyperbranched polyglycerols, FA-367 (a zwitterionic polymer), PDADMAC (Polydimethyl allyl ammonium chloride) and polyamines have been investigated [8].…”

In this work, a novel low molecular weight zwitterionic copolymer for improving wellbore stability, which is expected to be an alternative to the current shale inhibitors, was obtained by copolymerization of tris hydroxyethyl allyl ammonium bromide (THAAB), 2-acrylamido-2- methyl propane sulfonic acid (AMPS) and acrylamide (AM), initiated by a redox initiation system in an aqueous solution. The copolymer, denoted as SX-1, was characterized by FT-IR, TGA-DSC, and GPC. Results demonstrated that the molecular weight of SX-1 was approximately 13,683 g/mol and it displayed temperature resistance up to 225 °C. Regarding the inhibition performance, evaluation experiments showed the hot rolling recovery of a Longmaxi shale sample in 2.0 wt % SX-1 solutions was up to 90.31% after hot rolling for 16 h at 120 °C. The Linear swelling height of Na-MMT artificial core in 2.0 wt % SX-1 solution was just 4.74 mm after 16 h. Methods including particle size analysis, FTIR, XRD, and SEM were utilized to study the inhibition mechanism of SX-1; results demonstrated that SX-1 had entered into the inner layer of sodium montmorillonite (Na-MMT) and adsorbed on the inner surface, and the micro-structure of Na-MMT was successfully changed by SX-1. The particle size of Na-MMT in distilled water was 8.05 μm, and it was observed that its size had increased to 603 μm after the addition of 2.0 wt % of SX-1. Its superior properties make this novel low molecular weight copolymer promising for ensuring wellbore stability, particularly for high temperature wells.

“…In fact, a wide range of natural polysaccharides has been used as eco-friendly drilling fluids additives with nice viscosity-increasing property and compatibility with other materials. [12][13][14] In addition, as an important environmental protection additive for water based drilling fluids, nanoparticles show a good application prospect in petroleum industry, the benefits of nanofluids in water based drilling fluids include improvement of fluids rheological properties, reductions in filtration loss and friction coefficient, increase of the rate of heat transfer, shale stability improvement, and inhibition of gas hydrate formation. [15][16][17][18][19][20] Tree gums are natural polysaccharides consisted with multiple monosaccharides such as arabinose, galactose, glucose, mannose, xylose and uronic acids.…”

Excessive exploitation of non-renewable energy and environmental damage have forced people's scientific research turn to inexhaustible nature plants. In this work, carob bean gum (CBG) was modified using sodium chloroacetate as the modifier to enhance its solubility and efficiency in water based drilling fluids. The modification conditions were discussed through single factor test and screened as follows: the mass ratio of sodium chloroacetate to CBG was 20.0g/100g with pH 12 at the temperature of 50°C for 6 h. The rheological property and filtration loss of carboxymethylated carob bean gum (CCBG) treated drilling fluids were tested, which demonstrated more excellent rheological property and lower filtration loss than that of CBG. The inhibitive property of CCBG was evaluated by using Na-Bentonite (Na-MMT)-swelling tests and mud ball immersing tests, which showed that CCBG performed a high inhibitive and anti-caving capacities in water-based drilling fluids.
