... a high surface area to volume ratio allowing a greater efficiency for chemical interactions to occur. However, nanoparticle dispersions are often difficult to stabilize in harsh downhole environments. The dispersion can quickly become unstable and agglomerate when the fluid is subjected to changes in pH...

... to optimize the desired structure property relationship. Derivatization or — functionalization" further stabilizes the nanoparticles in different chemical matrices as well as activates them to directly bond/interact with their chemical environment. Thus functionalization is critical to the successful...

Moreover, at the level of NPs added, there was no material impact on drilling fluid viscosity and the fluid maintained its stability for more than 6 weeks. drilling fluid chemistry drilling fluid formulation commercial np formation damage drilling...

... and electrolytes concentration modifies the way that nanoparticles interact with the solution. In this work, the wettability and fluid diffusivity at the molecular level were studied through Molecular Dynamics simulation. We have studied the stability and mobility of functionalized (hydroxylated, PEG and sulfonic...

... Abstract Shale wellbore instability is a complex difficulty encountered during drilling all over the world. And the most important factor to determine shale wellbore stability is the distribution and expansion of micro-cracks in hard brittle shale. The usual ways to avoid collapse of shale...

... of some additives in gel-forming solutions; meanwhile the efficiency of the method remained the same or even better under various formation conditions. Based on earlier results, it was proved that addition of water-soluble polymers to silicates improved significantly the stability and flexibility...
