The well is usually full of drilling fluid when the casing is run into the well during drilling operations and prior to cementing operations. During casing placement, the casing will act as a piston or plunger, pushing the drilling fluid into the formation – unless the drilling fluid is able to flow back into the casing. Halliburton offers auto-fill assemblies that allow wellbore fluids to enter the casing as it is being run into the wellbore. Surge reduction float shoes and float collars reduce the effective wellbore surge pressure to help operators avoid losing valuable drilling fluid and damaging the formation.
