Fracturing Fluids and Ultra-Low Interfacial Tension: A Microscopic Revolution in Unconventional Oil and Gas Reservoir Development – Part Two: The Silent Killer – Water Locking Effect and Capillary Resistance Mechanism

Part 2: The Silent Killer — Mechanisms of Water Blocking and Capillary Resistance 2.1 Capillary Pressure: The Absolute Ruler in Nanopores In tight sandstone and shale matrices, pore throat radii are extremely small, typically ranging from nanometers to microns. This…
