“…Many nanoparticles are investigated to improve drilling fluid properties in the literature. Silica nanoparticles have been employed to decrease water absorption into shale formation and reducing drilling problems such as pipe sticking, shale hydration and wellbore stability [6,[14][15][16]. CMC nanoparticles have been applied for rheology improvement, filter cake thickness reduction and filtration control [9,17].…”

Application of nanoparticles in improvement of drilling fluid properties through effective control of fluid loss and rapid formation of thin, smooth and low permeable filter cake has gained considerable attention in recent years. In this study, calcium carbonate nanoparticle was synthesized by precipitation method and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope (SEM), dynamic light scattering and Zeta-potential measurement. Water based bentonite drilling fluid was used as base fluid. Various concentrations of calcium carbonate nanoparticle (0.025-0.5 wt%) was added to water-based drilling fluid. Fluid loss volume, filter cake thickness and its surface morphology, and rheological properties of both base fluid and fluid containing calcium carbonate nanoparticles was measured and compared. Results show that addition of calcium carbonate nanoparticle greatly affects filtration properties and forms smoother cake surface. Optimum concentration of 0.07 wt% calcium carbonate nanoparticle was obtained which results in reduction of fluid loss volume and filter cake thickness by 26% and 64% respectively while minor change in rheological behavior was observed. SEM image showed smoother cake surface of drilling fluid with calcium carbonate nanoparticle as additive compared to base drilling fluid. Considerable improvement in filtration properties using acid soluble CaCO 3 nanoparticles can help in minimizing fluid leak-off and formation damage of producing layers and more effective well cleanup for fast oil and gas production.

“…As depicted in Figure 1, the spectrum pattern of JAGO presented distinguished differences to that of GO. Specifically, the intensive peaks (in the range of 3,100-2,800 cm −1 ), which were attributed to the C-H stretching vibration of the alkyl group as well as the weaker peaks at 1,463 and 1,380 cm −1 , which were assigned to -CH 2 and -CH 3 (Acik et al, 2010;Huang et al, 2018), were observed in JAGO and not in GO. This was proof for the introduction of dodecylamine to GO.…”

Janus amphiphilic graphene oxide (JAGO), modified by dodecylamine on one side of graphene oxide (GO), was investigated for its novel use as a shale inhibitor. JAGO was synthesized by the Pickering emulsion template technology and was characterized by the Fourier-transform infrared spectra, UV-vis spectra, and transmission electron microscopy. Compared to KCl (5%), polyether diamine (2%), and pristine GO (0.2%), JAGO's highest shale recovery rate (75.2% at 80 • C) and lowest swelling height of Mt-pellets (2.55 mm, 0.2%) demonstrated its excellent inhibitive property. Furthermore, JAGO acted as a perfect plugging agent and greatly reduced filtration loss. Based on the results of X-ray diffraction, contact angle measurements, and pressure transmission tests, we proposed that the 2D nano-sheet amphiphilic structure of JAGO, which enabled it to be effective both in chemical inhibition and physical plugging, was responsible for its remarkable inhibition performances.

“…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.…”

“…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. But the polymer matrix has limited high-temperature resistance performance, leading to bad plugging performances in deep formation.…”

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.
