Sustainable Materials for Oil-Well Cementing Project (SMOC)



In this project, NCEL is collaborating with BRRI-CSIR to develop sustainable cementitious material purely from locally available feedstock that can replace up to 60% of Portland cement in oil-well cement slurries, reducing carbon footprint by over 56%.

A major source of CO2 emission from the oil and gas industry is the use of materials with high carbon and energy footprint, with Portland Cement been the notable. Portland cement production is responsible for about 5% of global CO2 emission and about 2% of global energy consumption. The oil and gas industry uses mainly Portland cement for oil-well cementing, each well consuming up to about 5 tonnes of Portland cement, depending on the depth of the well and other factors. Africa is home to five of the top 30 oil-producing countries in the world, contributing about 9.6% of the total world output. Yet, no single African country produces its own oil-well cement. The SMOC project is using locally available materials to develop, optimize, and standardize a low-carbon nano-based material capable of supplementing up to 60% of Portland cement in oil-well cement slurries. The success of this project will contribute significantly to the Net-Zero agenda of the E&P industry, fight against climate change, earn the country significant economic benefits and position Ghana as the first country in Africa to locally produce API standard oil-well cement.
