Drilling Performance Materials

Our products are used in a wide variety of applications

HDD (Horizontal Directional Drilling), tunnels, special foundations, mines and water wells, and geothermal drilling and waterproofing systems, to name a few.

Tunnelling

The specific characteristics of the special clays present in our products provide an excellent structure to the drilling muds, balancing wall pressure. That’s why they’re the perfect choice for use in tunnel boring machines.

Benefits:

  • Provides stability at the front of the excavation.
  • Excellent detritus carrying capacity.
  • Slurry stabilizer/filler mortars.
  • Improves mortar performance.
  • Allows injections into unconsolidated solids.
  • Increased drilling speed.
  • EPB (Earth Pressure Balance) SYSTEMS – TUNNEL BORING MACHINE
  • Provides stability at the front of the excavation.
  • Allows to conduct hyperbaric works.
  • Slurry stabilizer/compensation mortars.
  • Slurry stabilizer/filler mortars.
  • Spindle lubrication.
  • Increased drilling speed.

Applications:

  • Sludge
  • Tunnel boring machine
  • EPB (Earth Pressure Balance) Systems
  • Waterproofing solutions for large areas of land, ensuring a high safety coefficient for all types of contaminants

Oil & Gas

Tolsa has a wide range of additives specially designed for drilling fluids used in oil and gas exploration works. Our products are made to support water-based sludge as well as synthetic, oily, and saltwater based sludge.

Once incorporated into the drilling fluid, our additives act as high-performance viscous agents that stabilise the well and favour detritus removal. 

Thanks to its rheological properties and environmentally friendly nature, these additives are the perfect choice for hydraulic stimulation or fracking.

The increasingly extreme conditions in which oil exploration takes place makes choosing the correct drilling fluid crucial. Therefore, our solutions range has been carefully developed using various clays extracted from our mines worldwide, making our slurry additives a vital tool for developing conventional and unconventional oil drilling.

Benefits:

  • Acts as a stabiliser for grout used in well cementing.
  • Controlling water loss in permeable areas adjacent to the excavation.
  • Prevents dehydration and the premature setting of the cement.
  • Maintaining a high YP/PV (yield point/plastic viscosity) ratio even in saturated systems such as environments with high seawater or brine contamination.
  • To ensure the rheological equilibrium of sludge under such diverse conditions is due to the different variety of products made from different special clays, including bentonite, sepiolite and attapulgite.
  • Regardless of the water-cement ratio, they can be used in any slurry and show excellent behaviour when faced with high pressures and temperatures.

Applications:

  • Drilling fluids
  • Cementation

Mining

Thanks to its flexible composition, these additives provide water-based sludge systems with the rheological and filtration control properties required during demanding drilling operations.

Benefits:

  • Exceptional terrain waterproofing properties against contaminants for the correct sealing of underground works.
  • Provides water-based sludge systems with the rheological and filtration control properties.
  • Excellent rheological properties, maintaining a high YP/VP (yield point/plastic viscosity) ratio even in saturated systems such as environments with high seawater or brine contamination.
  • The ability to ensure sludge’s rheological equilibrium under such diverse conditions is due to the variety of products made from special clays, including bentonite, sepiolite, and attapulgite.

Applications:

  • Drilling fluids
  • Sealing
  • Tunnelling

Horizontal Directional Drilling (HDD)

Horizontal drilling must withstand greater earth pressure, compromising the stability of the tunnel and making it difficult to carry detritus to the outside of the excavation.

Therefore, for the correct execution of horizontal boreholes, it is necessary to use the appropriate tools that enable a combination of high carrying capacity with adequate stability, especially in certain conditions such as tunnels with huge diameters or in complex terrains.

Benefits:

  • Excellent terrain stabilisation capacity.
  • Optimum carrying capacity to keep the tunnel clean and avoid blockages: It allows the suspension of detritus, facilitating its extraction from the tunnel.
  • Maintains optimum rheology, even in cases of high contamination of sea water (drainage to the sea).
  • There are special grades based on sepiolite for exclusively marine environments.
