LLC Kyzylorda Refinery

In March, 2016 objects on TF “The system of collecting GOS and preliminary preparation of oil on the Taur field" are put into operation”:

• Central Processing Facilities (CPF) on collecting and preliminary preparation of GOS with a power - 209,1 tpd (73,19 thousand tons/year.) of oil.
• Oil gathering system from 6 well.

In September 2017, objects on TF "The system of collecting GOS and preliminary preparation of oil on the South Taur field " were put into operation:

• Central Processing Facilities (CPF) on collecting and preliminary preparation of GOS with a power of 542,86 tpd (190,0 thousand tons/year.) of oil.
• Oil gathering system from 21 wells.
• GTPP with a capacity of 0,8 MW to ensure power supply of group of fields of Khairkeldy and utilization of associated petroleum gas.
• GTPP with a capacity of 0,6 MW to ensure power supply of group of fields of Khairkeldy and utilization of associated petroleum gas.
• Total capacity of GTPP – 1.8MW.

As a result of the drilling and testing works of the well Zholtay 1 in January 2018, oil influx was received from the producing horizon M-II-1 aryskum deposits.

The deposit Zholtay was founded.

In April 2018, 6kV HV line from 6kV-SG  110/6kV PS “LLC Kyzylorda Refinery” Taur field power block were put into operation. 6 kV HR line length is 15,34 km.

Currently, LLP “LLC Kyzylorda Refinery” is operating on four fields Taur, Khairkeldy, South Khaikeldy, and North Khaikeldy; the field South-West Khairkeldy is on a trial operation; the fields Zholtay and North-West Khairkeldy are at the stage of estimation works.

In 2019, capital construction facilities were put into operation as part of the operation project “First Phase Equipping of the Facilities of the Kharkeldy Group of Oilfield”.

The project includes:

1. Booster pumping station (BPS) # 3 at the Khairkeldy Severny field with a multiphase pumping station with a pumping capacity of 3,600 m3 gas-liquid mixture per day.

4. The booster pumping station (BPS) # 2 at the Hairkeldy Central oilfield with a multiphase pumping station with a pumping capacity of 600 m3 of gas-liquid mixture per day.

5. Oil pipeline D219mm with a length of 2.06 km from BPS-2 of the Kharkeldy Central field to the D273mm pipeline.

6. Pipeline collection system D89mm with a total length of 36 km from 34 production wells in the Kharkeldy North, Central and South fields.

7. High-voltage power lines VL-6 kV with a total length of 24.4 km to the outfall of 34 production wells.

1.       The technology of dual operation (TDO) was introduced on wells No. 3,8,9 at Khairkeldy North, in order to improve the efficiency of artificial lift;

2.       Pilot field tests were carried out in five areas, in order to reduce operating costs in oil production and to apply new technologies;

3.       Capital construction facilities were put into operation under the Project “Infrastructure development for the Khairkeldy group of fields, 2nd stage”;

a.    Pipeline gathering system D89mm for 10 production wells at the Khairkeldy North, Khairkeldy South fields;

1.       Capital construction facilities were put into operation under the Project “Infrastructure development for the Khairkeldy group of fields, 3^rd  stage”:
