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.

In order to effectively solve shale instability problems in the drilling process, the remarkable capillary effect of shale formations cannot be ignored. In this paper, we report the development and characterization of a nanopolymer emulsion (SDPE) as a shale self-imbibition control agent in water-based drilling fluids. Spontaneous imbibition experiments, surface tension measurements, contact angle measurements, particle size distribution analysis, linear swelling tests, and hot-rolling cuttings dispersion tests were conducted to evaluate the comprehensive performance of SDPE. The results show that the water absorption of shale samples in SDPE emulsions is significantly less than in deionized water. At a concentration of 2.0%, the absorption mass decreased from 7.51 to 2.59%. Reducing the surface tension of the testing fluids, increasing the contact angle of the shale samples, and maintaining the nanoscale size were the important considerations for SDPE to greatly decrease the capillary effect. The low swelling rate and high recovery rate indicate that SDPE also exhibits strong shale hydration inhibition performance. Compared with waterbased drilling fluids without SDPE, drilling fluids with SDPE present higher yield point/plastic viscosity values, and also decrease the filtration loss. Based on our findings, SDPE has the potential to be a good shale self-imbibition control agent and to help mitigate the shale instability problems.

“…Zhong et al (2015cZhong et al ( , 2016 proposed the use of polyamidoamine dendrimers and reached very good shale cuttings recovery. However, dendrimers demand laborius multistep synthetic procedures, in contrary, polyglycerols are usually produced in simple one-step procedures (Parzuchowski et al, 2008).…”
