In Khanty-Mansi Autonomous Area (Western Siberia), a joint Russian-Swiss project to introduce a new type of gas compressor equipment for oil and gas production complex facilities has been implemented.



At the BPS-2 of Konitlor field of the Komsomolskneft oil and gas production department (Surgutneftegas PJSC), the Enerproject small gas compressor unit (SGCU) is transferred to routine operation. The SGCU became part of the low-pressure booster compressor station designed for the pumping of associated gas with inlet pressure close to vacuum (0...0.09 MPa).

The pilot operation stage lasted 10 months and completed with a set of final tests to assess the state of the SGCU and its compliance with the declared characteristics. In the course of the testing, the functioning of process, compressor, and electrical equipment and automated control system were checked under various modes of unit operation.



The SGCUs are designed on special (individual) projects and have a set of advantages in their operating segment: transportation by standard trucks; low pre-start costs; minimum commissioning period; low operating and maintenance costs; affordable price.

The implemented engineering solution makes it possible not only to operate such units in a stationary mode, but also to consistently use one SGCU at different sites. It is important to note that when you move the unit to another facility, you do not need to re-adjustment.

The "small" compressors can operate at facilities without complex infrastructure. There is provided the way for connecting supply lines with flexible pipelines, which makes it possible to integrate SGCU without retrofitting the existing gas pipeline system.

At the Konitlor oil field, the unit with capacity of 350 m3 / h carries out fine purification of associated gas from the end separation stage, its compression and injection into transport gas pipeline under pressure of 0.85 MPa.



The completed project has confirmed the operability and efficiency of this type of equipment in the climatic conditions of Western Siberia and its compliance with the operational requirements adopted at the facilities of Surgutneftegas.

Designing and production of SGCU were performed by the Swiss company Enerproject SA. The step-by-step commissioning of the unit (erection supervision, adjustment works, pre-start testing) and control over its pilot operation were conducted by the leading engineers of the ENERGAS Group which is exclusive partner of the Enerproject SA in Russia and the CIS countries.

The set of final tests has been carried out by the Surgut branch of the ServicENERGAS Company and was held with the participation of specialists of Surgutneftegas PJSC.
