Analyzing effects of multi-wall carbon nanotubes (MWCNT) & polyethylene glycol (PEG)

July 03, 2018

Nowadays, the maintenance of wellbore stability is a very important activity in the drilling industry. Wellbore stability can be improved by designing proper drilling fluid. Due to the characteristics of shale formations in relation to their ionic composition, clay content and very low Nano-Darcy permeability with very small nanometer-sized pore throats that are not effectively sealed by the solids in conventional drilling fluids, water invasion to these types of formations results in many problems. Choosing appropriate nanomaterials with suitable particle size and concentrations for plugging the nano-sized pores in the shale formations is key in preventing water flow into the shale region. Water base mud performance and rheological properties improve due to the importance and unique properties of MWCNT, such as thermal stability (at temperatures higher than 600 °C), high chemical stability, a significantly large surface area, a high aspect ratio, light weight, larger flexibility, high mechanical strength and superior electrical properties.
