“…Improvement in the sealing ability, reduction in mud cake permeability and wellbore stability was observed by adding nanoparticles compared to calcium carbonate as reported by Li et al (2012). Halali et al (2016) used CNT nanoparticle as an additive to drilling fluid for increasing thermal stability of polymeric fluid. The results showed reduction in filtration by 95% at high-temperature conditions and increase in stability and zeta potential of the shale.…”

Since almost all drilling problems directly or indirectly relate to drilling fluid, improvement in drilling fluid significantly enhances drilling operations. Drilling fluid contains base fluid, suspended solid particles and chemicals. Recently, nanoparticles have been widely recommended for improvement in drilling fluid properties. The main purpose of this study was to improve the rheological and filtration properties of water-based drilling fluid through adding new additive carboxyl methyl cellulose (CMC)/polystyrene core-shell nanocomposite. It compares filtration and rheological behavior of CMC, nanoCMC and core-shell nanocomposite. The core-shell nanocomposite was synthesized by miniemulsion polymerization method, and nanoCMC and core-shell nanocomposite were characterized by scanning electron microscope, transmission electron microscopy, particle size analyzer and thermogravimetric analysis. Fluid loss, mud cake thickness, viscosity, weight and pH of drilling fluid with core-shell nanocomposite additive were compared with conventional CMC (bulk CMC) and nanoCMC particles. Results showed a significant decrease in mud cake thickness and fluid loss when the core-shell nanocomposite was used, as compared with conventional CMC and nanoCMC. Viscosity of three additives has same trend with insignificant change while less yield point is obtained for drilling fluid containing core-shell nanocomposites. Mud weight and pH were almost the same for all three additives. Thus, the core-shell nanocomposite can be an alternative additive to control mud cake thickness and fluid loss while maintaining other main properties in an acceptable range.

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.

“…Different properties of WBM can be improved using polymers. Polymers are widely utilized to control filtration, improve rheological parameters, enhance cutting transport capacity, and improve shale recovery (Halali et al 2016). PAC, xanthan gum (XGD), carboxymethyl cellulose (CMC), starch, and partially-hydrolyzed polyacrylamide (PHPA) are the most commonplace polymers in drilling industry (Thomas 1982;Plank and Gossen 1991;Oswald et al 2006;Balestrini et al 2009;Kelessidis et al 2013;Toka and Toka 2015;Villada et al 2017).…”

One of the disadvantages of polymers is their low performance in high-temperature and high-pressure (HPHT) conditions which bring about the degradation of polymers (Halali et al 2016). Thomas (1982) showed that the thermal stabilities of starch and CMC are in the range of 200-225 °F and 275-300 °F, respectively.…”

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.
