Ultra-Block®

instant filtering composition
Solving problems of loss of full or partial circulation of drilling fluid in the drilling process.

Benefits:

  • Fractured rocks and highly permeable formations.
  • Creating an impermeable for drilling fluid plugging screen.
  • Independent of time, pH, activators product.
  • Easy to prepare.
  • Basis can be any technical water: fresh, reservoir, mineralized

Important: there should be no polymers in the water used that are filtration reducers.

Ultra-Block® – process simulation

  • Filtration process and compaction screen impermeable to drilling fluid.
  • While maintaining pressure, water is filtered from the drilling fluid.
  • A filter crust is formed on the surface of the impenetrable screen.

Ultra-Block® - Instant Filtration

  • The screen is a "plug" permeable to water and impermeable to the drilling fluid.
  • Standard cementing equipment is used at installation - USO and TsA-320.
  • The creation of pressure during installation is created by sealing the wellhead (for example, to close the blowout preventer).
