Description
Hao Bai and ten co-authors develop a fracturing fluid in a study from two thousand twenty-four. Deep, hot reservoirs are hard to fracture because standard polymer fluids grow viscous too fast and raise wellbore friction. Their fluid responds to pH, so its thickening can be delayed and controlled.
Tests showed cross-linking runs fast in acid, while alkali slows it and cuts friction. Sodium carbonate proved an effective control agent. Their two-stage recipe keeps viscosity low while cracks form, then raises it to carry sand. Microscopy and spectroscopy showed how pH reshapes the polymer network and charge. Field tests gave lower operating pressures and steady sand transport, with notable oil and gas output.
