Project name:

4th Injection Compressor Project (4ICP)

Location:

Karachaganak (Kazakhstan)

Contractor:

Bonatti S.p.A.

Client:

Karachaganak Petroleum Operating (KPO)

Year:

2019-2020

Project Description:

The 4th Injection Compressor Project consists of a Compressor Island with a three-stage centrifugal compressor driven, through a speed increasing gear box, by a MS5002D gas turbine, and an associated dry, sour process gas seal system. The compressor final configuration, approximately 220m west of the existing reinjection trains at Unit 2.

The 4ICP will increase re–injection flowrates from an average of 31 MMsm3/d up to an average of 38.9 MMsm3/d. Injection flowrates will be maximised as part of the 4ICP system design optimisation and may enable injection flowrates of up to 41.6 MMsm3/d (during winter months) to be achieved. The new compressor will have dry feed gas supplied from the new KPC 26” Export line, under development by the KGDBN project
