-ULW proppant are easy to transport and reduces the damage related to transport.
-Perform sand control treatment by using the composition reduces the fluid loss and improves the wellbore productivity....[Contd]
 ===Information from the Articles=== Pearce et. al., 2002 of The '''Houston Exploration Co '''studied on successfully pushing the limits in tight gas fracturing. A South Texas tight gas field was fractured using '''LPF (Lower-polymer fluid) system'''. LPF system avoided the proppant damage due to less polymer residue, and improved well productivity through increased fracture conductivity. Gupta et. al., 2011 studied Associative polymer systems that extend the temperature range of surfactant gel frac fluids. New thickening system for fracturing was prepared using viscoelastic Surfactant (VES), low molecular weight associative polymer and three or four additives compound. New thickening fracturing fluid showed good clay control, friction reduction, water wetting and post frac fluid recovery characteristics and could be easily converted into high temperature stable foam....[Contd]
