Special Issue Information

Dear Colleagues,

Energy supply from fossil fuels and geothermal resources, geological disposal of waste and sequestration of CO2 play important roles in our world, and these entities have interactions in common with the subsurface environment as part of the process. Hence, drilling wells, production operations and plug and abandonments are among the technical challenges across these sectors. In drilling and production operations, suspension systems such as drilling, fracturing and well completion fluids; and cement slurries are needed to drill the well and manage the flow safely and favourably. The dynamics and rheology of such suspensions and their performance are critical for efficient and economic operations. Recent advances in particle technology have shown promising outcomes regarding the use of the nanomaterials in suspensions (e.g., in drilling and completion fluids) to mitigate issues such as high-temperature conditions, frictions in flow and environmental concerns. In this Special Issue, the aim is to provide a platform to share advances in adapting the novel suspension systems for applications in drilling and fracturing fluids, blocking agents, cement slurries, and other fluids that are used downhole. Their dynamics and physiochemical characteristics are vital for the industry to consider their use in field operations. We would like to invite authors who have conducted theoretical, field trial or experimental studies of nano-enhanced fluids for oil and gas drilling, and production applications share their outcomes with the industry and scientific community in this Special Issue.

Esters were found to be promising alternatives to oil, as a constituent of drilling fluids, due to their biodegradability and bioaccumulation attributes. In this study, we used ethyl octanoate ester (EO) as a low molecular weight synthetic oil for formulating an ester-based drilling fluid (EBDF). Aluminum oxide nanorods (nanoparticles) were introduced as a Pickering emulsion stabilizer. Like the commercial emulsifiers, they showed that they stabilized the invert emulsion drilling fluid in our study. The rheological and filtration properties of the EBDF were tested at normal pressure and three temperatures: low temperature deepwater (LT) conditions of 2.6 °C, normal pressure and normal temperature (NPNT) conditions of 26.8 °C, and elevated temperature conditions of 70 °C. To enhance the stability and filtration properties of the drilling fluid, aluminum oxide nanoparticles (NPs) were used. An optimum concentration of 1 wt% was found to provide superior rheological performance and higher stability than samples without NPs at NPNT, LT, and elevated temperature conditions. Steadier gel rheology was exhibited at elevated temperature conditions, and a slow rate of an increasing trend occurred at the lower temperatures, with increasing NP concentrations up to 1.5 wt%. Filtration loss tests presented a reduction of fluid loss with increasing the NP concentration. The results demonstrate that a reduction of up to 45% was achieved with the addition of 1 wt% NP. These results show that nano-enhancement of ethyl octanoate drilling fluids would suffice to provide a wider range of operational temperatures for deepwater drilling operations by providing better thermal stability at elevated temperatures and maintaining stability at lower temperatures.
