  • METHOD FOR INTERVENTION OPERATIONS IN SUBSURFACE HYDROCARBON FORMATIONS
    Publication number: 20120175120
    Abstract: Nanoparticles are added to a fluid containing a wetting agent and the fluid is pumped down a well to enhance wetting of solid surfaces in and around the well before pumping an acid solution down the well. After acid is pumped, a fluid containing nanoparticles and wetting agent is again pumped down the well, leading to improved flow capacity of the well.

  • METHOD FOR INTERVENTION OPERATIONS IN SUBSURFACE HYDROCARBON FORMATIONS
    Publication number: 20120168165
    Abstract: Nanoparticles are added to a fluid containing a wetting agent to enhance wetting of solid surfaces in and around the well and removing a water-block from the well. The wetting agent and nanoparticles combine to produce a wetting of the surfaces of the rock that allows recovery of the excess water near the well (water block).
