CONFORMITY CERTIFICATE

CERTIFICATE OF CONFORMITY TO THE SYSTEM OF VOLUNTARY CERTIFICATION INTERGAZSERT

Mobile units for survey, gathering and processing of wells are designed for automated measuring of well flow rate at various wellhead pressures, as well as separation of oil from gas and water, followed by filling in tank trucks, feeding into the oil&gas gathering system, flare recycling, gas treatment for own use supply to the gas gathering system or electricity generation on site.

Equipment composition:

PKIOS equipment is made in block design on a frame base. 

Parts of mobile units can be installed:
  • on skid
  • on chassis
  • on a semitrailer

Overall view

Advantages of mobile units in comparison with capital construction facilities 

  • flexible system of parameters selection and equipment package;
  • full factory readiness of the complex unit;
  • compact dimensions and aesthetic appearance;
  • mobility and ease of movement;
  • reduced terms of mounting/dismounting;
  • ease of assembly interunit pipes by the quick-release connect;
  • operation in remote maintenance mode without the constant presence of personnel.
