Recently had positive results from two well treatments (inefficient displacements) that doubled natural gas production, more than doubled SI and flowing pressures and increased water production (unrecovered treatment water, not formation water). Considering performing a more efficient displacement. I would like to hear from others with experience treating wells with nano (surfactants or other) that could reverse Capillary Phase Trapping (CPT) damage in tight gas sand formations with sub-irreducible water saturation.
