“…As the circulating uid between the downhole drilling tool and the borehole wall, drilling uid plays an important role in reducing friction. [6][7][8][9] The drilling uid forms a lter cake on the surface of the well wall so that the contact between the drill pipe and the well wall becomes the contact between the drill pipe and the lter cake. By improving the lubricity of the lter cake, the frictional resistance to the drill pipe can be reduced.…”

“…Oil-based drilling fluid has many advantages, such as stable performance, strong antipolluting ability, and strong inhibition, and is widely used in China. The cementing quality under this condition is greatly affected by the effectiveness of the isolation fluid. − Cementing displacement has always been a difficulty and key point in cementing research. − For more than half a century, scholars around the world have performed systematic and in-depth studies on the mechanism and process of cement injection displacement …”

The annulus has a wide and narrow clearance due to casing eccentricity in the cementing process and due to the eccentricity of casing in the process of cementing. Because the flow resistance of the drilling fluid in the wide gap is less than that in the narrow gap, the phenomena of a delayed flow or even an overall nonflow occurs in the narrow gap. Based on the existing displacement efficiency calculation model, this paper establishes the cementing displacement efficiency model under the condition of oil-based drilling fluid, explores the residual layer thickness of drilling fluid on the casing side and the sidewall side, and then links the annular displacement efficiency to the injection displacement in combination with the circulating mode resistance pressure drop formula so as to explore the change in the cementing displacement efficiency under different displacements. Considering the change in the physical parameters of annulus fluid, the change in annulus displacement efficiency is obtained. On this basis, the relationship between the wellhead cement injection flow and the annulus retention layer is studied; then, the displacement is calculated. The reasonable cementing displacement is calculated by combining the displacement with annulus displacement efficiency. The results show that the thickness of the annular detention layer increases with the increase in the casing eccentricity in the same well depth, and the growth rate of the detention layer on the wellbore side is greater than that on the casing side at the same circumferential angle. The greater the displacement, the greater the annular circulation pressure drop and circulation equivalent density, thus increasing the cementing risk. The displacement is reasonably designed. The research results in this paper have a certain guiding significance for improving the displacement rate of isolation fluid under oil-based drilling fluid conditions.

“…Typically, water-based fluids (WBFs) are more preferred for fracturing processes. − The WBFs employed for hydraulic fracturing are however challenged by (1) the presence of swelling clays in the reservoir and (2) the low viscous nature of the WBFs. Regarding the first, the clay minerals present in the formation often react with the WBFs, resulting in the swelling of the formation, generating a myriad of issues .…”

In this paper, we present the results of the rheometric properties of a guar-based fracturing fluid containing amino-acid clay stabilizers. Four amino acids, glycine, proline, alanine, and arginine were selected for the study. KCl, a conventional clay stabilizer, was also used for comparison. The fracturing fluid was prepared using tap water (97.3 wt %), guar gum (0.4 wt %), ethylene glycol (0.1 wt %), potassium carbonate (0.2 wt %), and a clay stabilizer (2 wt %). A Discovery Hybrid rheometer with a bob-in-cup measuring system was used to determine the fluids’ viscoelastic and temperature-dependent properties under both static and dynamic oscillatory conditions. The static tests were employed at varying shear rates of 0.001–1000 s–1 from 25 to 90 °C, mimicking both room and reservoir conditions. For the oscillatory measurements, amplitude and frequency sweep tests were done at a strain ranging from 0.001 to 100% and a frequency ranging from 0.01 to 100 rad/s. The rheological characterizations of the fracturing fluids confirmed that amino acids did not negatively affect the base fluid’s viscoelasticity, flow behavior, shear-thinning properties, and pumpability, including its damping factor. Glycine and alanine enhanced the shear-thinning property of the base fluid by 4 and 5%, respectively. All the stabilized fluids displayed significant upsurges in their elasticity as the frequency was increased from 0.01 to 100 rad/s. Proline, glycine, and alanine improved the base fluid elasticity by reducing its damping factor value by 0.37, 0.20, and 0.14, respectively. Alanine on the other hand increased the base fluid’s damping factor value by 0.12. This study provides new insights into the rheological abilities of hydraulic fracturing fluids containing amino acid additives and how their presence in the fracturing fluid contributes to the effective transportation and dropping of proppants. These insights are necessary for evaluating the effects of additives on the fracturing fluid gel structure, proppant carrying and packing capacity, gelling time, temperature stability, and, more importantly, its structural stability.
