Nutshells are a product obtained from ground hazelnut shells. The product is used in the technology of oil drilling as a material for preventing and eliminating drilling mud leaks. Ground nut shells are a particularly effective material for liquidation of mud leaks occurring in cracked and fissured rocks.

The product is supplied in three granulations:

  • Nutshells fine – fine-grained granulation with a particle size of 0.5 – 2.0 mm;
  • Nutshells medium – medium grain granulation with a particle size of 1.0 – 3.0 mm;
  • Nutshells coarse – coarse granulation with a particle size of 2.0 – 4.0 mm;


The use of the product depends on the intensity of leaks and the type of rocks. Preventively, we recommend using Nutshells Fine in the amount of 12-18 kg per 1 m3 of drilling fluid.

To eliminate leaks, use Nutshells Medium and/or Nutshells Coarse in quantities of 25-50 kg per 1 m3 depending on the size of the fissures in the rocks and the volume of the leaks.
