“…Various rheological measurements, including the determination of gel strength, flow curve analysis, and assessment of fluid stability, were performed at ambient temperature. The objective of these rheological measurements was to identify the optimal drilling mud formulation by considering factors such as gel strength and the modification of thixotropic properties of the drilling fluid 24 , 43 .…”

Formation damage is a well-known problem that occurs during the exploration and production phases of the upstream sector of the oil and gas industry. This study aimed to develop a new drilling mud formulation by utilizing eco-friendly bio-polymers, specifically Carboxymethyl Cellulose (CMC), along with nanostructured materials and a common surfactant, sodium dodecyl sulfate (SDS). The rheological properties of the drilling fluid and the impact of additives on its properties were investigated at the micromodel scale, using a flow rate of 20 mL/h. The polymer concentration and nano clay concentration were set at two levels: 0.5 wt% and 1 wt%, respectively, while the surfactant content was varied at three levels: 0.1 wt%, 0.4 wt%, and 0.8 wt%. The results of the interfacial tension (IFT) analysis demonstrated a significant decrease in the interfacial tension between oil and water with the increasing concentration of SDS. Furthermore, following the API standard, the rheological behavior of the drilling fluid, including the gel strength and thixotropic properties of the mud, was evaluated with respect to temperature changes, as this is crucial for ensuring the inherent rheological stability of the mud. The rheological analysis indicated that the viscosity of the mud formulation with nanoparticles experienced a reduction of up to 10 times with increasing shear rate, while other formulations exhibited a decline of 100 times. Notably, the rheological properties of the Agar specimen improved at 150 °F due to its complete solubility in water, whereas other formulations exhibited a greater drop in viscosity at this temperature. As the temperature increased, drilling fluid containing nanostructured materials exhibited higher viscosity.

The capability of drilling fluid to endure high temperature and stabilize shale cuttings is important characteristics of drilling fluids. In this work, a combination of 1,6-hexamethylenediamine and polyanionic cellulose (PAC) was tested to observe the impact of 1,6-hexamethylenediamine on thermal stability of PAC and its influence on the shale cutting stability of drilling fluid. First, rheological parameters and filtration control were examined at four different temperatures (325 °F, 350 °F, 375 °F, and 400 °F). Then, the cutting disintegration test was performed at 250 °F to evaluate the effect of 1,6-hexamethylenediamine on shale cutting stability. Experimental results showed that adding 1,6-hexamethylenediamine to drilling fluids effectively increases the thermal stability of the rheological parameters of drilling fluids such as apparent viscosity, plastic viscosity, yield point, and gel strength up to 350 °F. It was also concluded that when 1,6-hexamethylenediamine is added to drilling fluid, the amount of fluid loss is in acceptable range up to 375 °F. Finally, the results indicated that 1,6-hexamethylenediamine significantly increases the shale cutting recovery.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
