Shaped cutters outperform conventional designs in hard limestone: ridge cutters reduce peak force by ~8.7% and MSE by ~34%, enabling faster ROP and more efficient drilling. #openaccess at https://shortlink.uk/1n8uL. #Geomechanics #rockmechanics #basin

New insights into CO₂-N₂-CH₄ interactions in tight sandstone: molecular simulations reveal CO₂ dominates adsorption, while N₂ enhances CH₄ diffusion at high pressure—enabling efficient CO₂-EGR strategies. #openaccess at https://shortlink.uk/1rPKL. #CCUS #EGR #NaturalGas #EnergyTransition

A new 3D CT–fractal method quantifies coal fracability via fracture surface area. Lower stress contrast and CO₂ fracturing boost complexity by up to 50%. #openaccess at https://shortlink.uk/1mfxL
