“…The D 50 (median particle size) was 62 nm, while the D 10 value was 44 nm and the D 90 value was 88 nm. Based on previous reports (Liu et al, ; Xu, Qiu, Huang, & Zhao, ), it can be inferred that the polymer nanoparticles in this size range can bridge and seal the micro‐/nano‐scale pore‐throats developed in shale formations. Finally, a dense plugging film can form on the shale surface, thus further reducing filtrate invasion.…”

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.

“…However, these micron-level plugging agents could not plug nanoscale pores because their size is too large. Considering matching of size and according to many studies (Taha and Lee, 2015;Xu et al, 2017;Huang et al, 2018b), the nanoscale plugging agent is essential to wellbore stability of troublesome formation.…”

“…Some research studied the effect of other inorganic nanoparticles on the wellbore stabilizing performance of drilling fluid such as nano grapheme (Taha and Lee, 2015), nano TiO 2 (Cheraghian et al, 2014), and nano MgO (Alssafar and Al-Mahdawi, 2019). Nano polymers (Xu et al, 2017(Xu et al, , 2018Zhang et al, 2018) having good flexibility could plug irregular shale pores by transformation and have strong interaction with shale matrix. Polymer/inorganic nano composites (Wu et al, 2016;Huang et al, 2018b;Qiu et al, 2018) combining the advantages of polymeric and inorganic plugging agents are another research hotspot.…”

Nanoscale plugging agent is essential to wellbore stability of troublesome shale formation in the drilling of oil and gas wells. In this paper, polymeric nanospheres (PNS) with a double cross-linked structure were synthesized using monomers of styrene (ST), acrylamide (AM), 2-Acrylamide-2-methylpropanesulfonic acid (AMPS), and dimethyl diallyl ammonium chloride (DMDAAC). PNS were characterized by FTIR, SEM and TGA. The plugging performance of PNS was analyzed using nitrogen adsorption experiments and SEM. And compatibility with water based drilling fluid (WBM) was studied. Experimental results showed that PNS had a mean particle size of 133 nm, and could retain about half of the original size after high temperature treatment under 150-200 • C. TGA showed that the initial decomposition temperature of PNS is around 315 • C. After plugging by PNS, both the specific surface area and pore volume of the shale cuttings decreased substantially compared with those of shale samples treated with water. Thus, PNS was thermal stable in WBM under high temperature and could effectively plug shale pores. Besides, PNS was beneficial to reduce both API and HTHP fluid loss of WBM.

“…Recently, various nano-plugging materials have been introduced into WDFs, such as silica nanoparticles, graphite and polymer latex. 18,[23][24][25] Non-modied silica nanoparticles were rst used as plugging agents in WDFs, and they could dramatically reduce the invasion of water into shale. 26 However, they easily aggregate and it is difficult to achieve nano-plugging performance with them.…”

Interest in using nanomaterials to improve shale stability during drilling operations has been increasing.Herein, a polymer microsphere emulsion (PME) as a high-performance shale stabilizer for water-based drilling fluids (WDFs) was prepared via emulsion polymerization. The particle sizes in PME in aqueous solution ranged from 90 to 320 nm. PME was found to exhibit excellent salt tolerance and temperature resistance. The plugging performance of PME was tested through pressure transmission tests. The results indicated that the polymer microspheres in PME could effectively plug shale pores and reduce shale permeability. In addition, rolling recovery tests were used to evaluate the shale hydration inhibition performance of PME. It was found that PME showed great performance for decreasing shale hydration potential. These factors make PME a promising shale stabilizer for WDFs used to drill shale formations.
