Conversion of Drill Cuttings into High-Performance Geopolymer Construction Materials

Abstract Drilling operations in the oil and gas industry produce an enormous number of drill cuttings that create considerable environmental, regulatory and economic challenges. Traditionally in the form of landfilling, reinjection or offshore discharge, drill cuttings are being subject to greater scrutiny because of their environmental footprint as well as long term liability. In parallel, there exist pressures mounting from within the construction industry to curb carbon emissions linked to the production of the iconic material - Portland cement. Against this context, development of use cases on the utilization of drill cuttings for the production of geopolymer-based construction materials offers a viable way ahead for circular resource use and low carbon infrastructure deployment. This study examines the technical feasibility, the environmental characteristics and the material properties of geopolymers prepared from treated drill cuttings. Using mixed experimental-analytical approach, the research experimental and analytical evaluations are conducted for chemical activation mechanism, mechanical performance, durability characteristics, and lifecycle implications of drill cuttings based geopolymers. Results show that re-processed and activated drill cuttings can be useful as valuable primers for high performance geopolymer binders that exhibit compressive strength comparable to conventional materials based on cement and with a considerably lower waste volume and greenhouse gas emissions. The findings make drill cuttings valorization a potential scalable and sustainable solution tackling the interests of waste management and green construction.
