CUSTODY TRANSFER SYSTEMS

 

Коммерческий учет нефтиOne of the legacy activities of Quantor Group is commissioning, maintenance and metrological support of commercial oil & gas custody transfer systems. An accurate measurement of consumed energy is now becoming increasingly essential due to inevitably growing energy tariffs.

Maintenance of oil and gas custody transfer systems is essential in failure reduction, due to timely preventive and routine procedures, a regular inspection of the facilities, recommendations for the customer, and contribution to upgrade and retrofit project development.

We plan and carry out activities in strict compliance with the approved scopes and maintenance schedules, relying on the following guidelines:

  • Oil Weight Definition Recommendations for Metering Operations Using Oil Quality and Quantity Measuring Systems; and
  • MI 3081-2007, Quality and Quantity Measuring Systems of Crude Oil, Light Oils and Liquid Hydrocarbons. Maintenance and Repair. General Provisions.

Quantor Group:

- carries out survey and initial exploration of hydrocarbon custody transfer systems,

- makes up a technical assignment for customer approval and further approval with the National Research Metrology Centre,

- carries out detailed design engineering,

- carries out metrological and industrial safety expert review,

- has the design registered with the local Rostekhnadzor branch,

- selectes, integrates and delivers equipment,

- carries out construction, installation, electrical installation, and commissioning,

- develops equipment operation manuals,

- performs pilot operation,

- provides customer personnel training,

- provides maintenance of oil and gas custody transfer systems,

- provides metrology services (instrument verification, development of measurement procedures, registration with the State Register).

 

Quantor Group offers a wide scope of metrology services for metering systems (hydrocarbons and petroproducts, gas, heat, water).

The Company is proud of its long-standing cooperation with the national authorities and metrology centres in Russia and Kazakhstan, including Kazakhstan Institute of Metrology (KIM), National Centre for Expertise & Certification (NCEC), Mendeleyev Institute for Metrology (VNIIM), All-Russian Research Institute of Flow Metering (VNIIR).

МетрологияQuantor Group owns metrological and verification laboratories for instrumentation verification, calibration and repair. The accreditation scope covers :

  • liquid flow transmitters,
  • temperature & pressure transmitters,
  • level transmitters,
  • oil moisture meters,
  • density and viscosity transmitters,
  • gas analyzers, etc.

The instrumentation stock includes high-precision portable reference standards manufactured both abroad and in Russia, auxiliary instruments, and calibration gas mixtures. There are approximately 400 units of test and measuring equipment enabling performance (mostly on-site) within the accreditation scope: 

  • pyknometers (H&D Fitzgerald Ltd),
  • coulometers (Mettler Toledo),
  • vibration level device calibration rigs (ВСВ-131),
  • waterdraw systems (Potok-1),
  • versatile calibrators (types MC5-R, TRX-II),
  • portable pressure, temperature, electrical and current calibrators.

 

We ensure better accuracy of hydrocarbon measurements, as the metrological services include:

- upgrade of standard equipment,

- development of new or modification of measurement procedures followed by registration with the State Register of the Republic of Kazakhstan.

 

Quantor Group is a current contractor of the Caspian Pipeline Consortium for maintenance and metrology services of oil custody transfer systems of the Tengiz-Novorossiysk oil pipeline.
