Nanomaterials are engineered materials with at least one dimension in the range of 1-100 nm. Nanofluids-nanoscale colloidal suspensions containing various nanomaterials-have distinctive properties and offer unprecedented potential for various sectors such as the energy, cosmetic, aerospace and biomedical industries. Due to their unique physico-chemical properties, nanoparticles are considered as very good candidates for smart drilling fluid formulation, i.e., fluids with tailor-made rheological and filtration properties. However, due to the great risk of adapting new technologies, their application in oil and gas industry is not, to date, fully implemented. Over the last few years, several researchers have examined the use of various nanoparticles, from commercial to custom made particles, to formulate drilling fluids with enhanced properties that can withstand extreme downhole environments, particularly at high pressure and high temperature (HP/HT) conditions. This article summarizes the recent progress made on the use of nanoparticles as additives in drilling fluids in order to give such fluids optimal rheological and filtration characteristics, increase shale stability and achieve wellbore strengthening. Type, size and shape of nanoparticles, volumetric concentration, addition of different surfactants and application of an external magnetic field are factors that are critically evaluated and are discussed in this article. The results obtained from various studies show that nanoparticles have a great potential to be used as drilling fluid additives in order to overcome stern drilling problems. However, there are still challenges that should be addressed in order to take full advantage of the capabilities of such particles. Finally the paper identifies and discusses opportunities for future research.

Analiza wpływu nanomateriałów na właściwości osadu filtracyjnego W artykule przedstawiono wyniki badań nad doborem stężenia nanokrzemionki hydrofobowej oraz innych składników do płuczki wiertniczej, zapewniających uzyskanie stabilnych parametrów reologicznych i niskiej filtracji w warunkach otworopodobnych. Opisano badania nad określeniem wpływu dodatku nanokrzemionki i mikrokrzemionki oraz środków powierzchniowo czynnych na parametry reologiczne, filtrację API i HPHT oraz właściwości inhibitacyjne opracowanych płu-czek wiertniczych. W dalszej części artykułu przedstawiono wyniki badań przyczepności kamienia cementowego do skał, na powierzchni których utworzyły się osady z badanych płuczek, oraz skuteczności usuwania tych osadów przez ciecz przemywającą. Na podstawie przeprowadzonych badań zaproponowano składy płuczek zawierających nanokrzemionkę hydrofobową dyspergowaną w poliglikolu w połączeniu ze środkami powierzchniowo czynnymi oraz mikrokrzemionke.Słowa kluczowe: płuczka wiertnicza, nanomateriały, nanokrzemionka, mikrokrzemionka, osad iłowy. Analysis of the effect of nanomaterials on the properties of filter cakeThe article presents results of research on the choice of hydrophobic silica nanoparticles and other components concentration in the drilling fluid, that ensures stable rheological parameters and low water loss in borehole conditions. Studies to determine the effect of nanosilica, microsilica and surfactants additions on rheological parameters, inhibition properties, API and HPHT filtration of prepared drilling fluids were described. The following section presents the results of adhesion tests of cement stone to rocks, on which sediment from the scrubbers was formed, and the efficiency of removing these sediments from the washing liquid. Based on the laboratory study, a drilling fluid composition containing a hydrophobic nanosilica dispersed in a polyglycol in combination with surfactants and microsilica was proposed.

“…The pore diameter of gas shales in China and North America ranges from 5 to 300 nm and 8 to 100 nm, respectively [11][12][13][14][15][16][17]. Therefore, the past decade has seen an increase in NP use to improve wellbore stability in shales [18][19][20][21][22][23][24][25][26][27][28][29][30][31]. To assess wellbore stability in the presence of NP, triaxial failure tests, pressure transmission tests (PTTs), and modified thick walled cylinder (TWC) tests with drilling fluid exposure have been recommended by van Oort et al [32].…”

Abstract:The past decade has seen increased focus on nanoparticle (NP) based drilling fluid to promote wellbore stability in shales. With the plugging of NP into shale pores, the fluid pressure transmission can be retarded and wellbore stability can be improved. For better understanding of the interaction between shale and NP based drilling fluid based on previous pressure transmission tests (PTTs) on Atoka shale samples, this paper reports the numerical simulation findings of wellbore stability in the presence of NP based drilling fluid, using the 2D fluid-solid coupling model in FLAC3D™ software. The results of previous PTT are discussed first, where the steps of numerical simulation, the simulation on pore fluid pressure transmission, the distribution of stress and the deformation of surrounding rock are presented. The mechanisms of NP in reducing permeability and stabilizing shale are also discussed. Results showed that fluid filtrate from water-based drilling fluid had a strong tendency to invade the shale matrix and increase the likelihood of wellbore instability in shales. However, the pore fluid pressure near wellbore areas could be minimized by plugging silica NP into the nanoscale pores of shales, which is consistent with previous PTT. Pore pressure transmission boundaries could also be restricted with silica NP. Furthermore, the stress differential and shear stress of surrounding rock near the wellbore was reduced in the presence of NP. The plastic yield zone was minimized to improve wellbore stability. The plugging mechanism of NP may be attributed to the electrostatic and electrodynamic interactions between NP and shale surfaces that are governed by Derjaguin-Landau-Verwey-Overbeek (DLVO) forces, which allowed NP to approach shale surfaces and adhere to them. We also found that discretization of the simulation model was beneficial in distinguishing the yield zone distribution of the surrounding rock in shales. The combination of PTT and the 2D numerical simulation offers a better understanding of how NP-based drilling fluid can be developed to address wellbore stability issues in shales.
