Class Information
Number: 166/309
Name: Wells > Processes > Producing foam or gas in well by foaming or gas producing material
Description: A process comprising introducing a material into the well which by interreaction with fluid already in the well acts as a foaming agent in the well or by its own change of state causes production of gas bubbles or foam.
