The foam used in foam drilling with Amrfeo is created by mixing a surfactant (foaming agent) with water and air. This mixture produces a stable foam that is injected into the wellbore. The foam acts as a medium to carry the drilled cuttings to the surface, allowing for easy removal and preventing them from settling back into the borehole. The foam also helps maintain borehole stability by exerting enough pressure to prevent the walls from collapsing while avoiding excessive pressure that could d
