Drilling Mud Zero Discharge Treatment

Drilling mud from different stages goes through solid-liquid separation, stable solidification and liquid recycling through chemical and physical methods. The system is highly integrated with modular skid mounted equipment for different needs.

Drilling mud is produced in reservoir exploration and development. The waste mud consists of a large quantity of hydrocarbons, heavy metals, minerals and macromolecule organic compounds,  which can cause potential damage to the surrounding soil. Currently, two methods are commonly used in mud treatment, but none of them are perfect. The solidification and landfill technique cannot treat the mud completely and such a method may take up arable land. The other way of constructing treatment plants may give rise to much cost in transportation and secondary pollution. Alternatively, Haimo ESG has developed a new mud control technique and treatment, resulting in no contact between soil and waste mud, which has been applied to most of the major fields in China.

The large grains from the Shale Shaker produces solids and liquid mud after flushing and dehydration. This liquid, in addition with other liquid from the Desander, Desilter and the Centrifuge; undergoes destabilization dosing, and separates through the filter press. The resultant liquid returns to the Mud Circulatory System, where the solids are treated safely together.

Treated liquid:
pH7.0-8.5
Mud Density≤1.08g/cm3
Sand Concentration≤0.15%
Funnel Viscosity≤25s
Treated Solids(Extract)
pH6~9
CODcr≤100
Heavy MetalQualified
Hydrocarbon≤10
  • Treatment is conducted while drilling - ensures no damage to the surrounding soil.

  • Flexible treatment methods - different unit combinations can be applied according to specific well site, drilling stage and mud system.

  • Good treatment results - stable solidified products can be used for site substructure and roadbed construction, whereas the liquid could be used to prepare drilling mud.

  • Skid mounted - standard size, easy transportation and fast installation.
