Kalamkas Oil Field Profile

Location

The Kalamkas Oil Field is located in two distinct areas:

• The onshore field is situated in the Mangistau Region in western Kazakhstan.
• The offshore component, known as the Kalamkas-Sea field, is located in the central part of the North-Eastern part of the Caspian Sea, with sea depths ranging from 7-8 meters.

Operator and Ownership

• The onshore Kalamkas Oil Field is operated by Mangistaumunaigaz AO (MMG), a subsidiary of KazMunayGas and China National Petroleum Corp (CNPC).
• The offshore Kalamkas-Sea field is jointly developed by JSC NC KazMunayGas and PJSC Lukoil, with each company holding a 50% stake in the Kalamkas-Khazar Operating LLC.

History and Discovery

• The onshore Kalamkas Oil Field was discovered in 1976, with the first production starting in 1979.
• The offshore Kalamkas-Sea field saw the successful completion of its first exploration well in 2002.

Production and Reserves

• Onshore Field:
  • The field has recoverable oil reserves of approximately 449.52 million barrels as of 2017.
  • Total balance oil reserves are estimated at 3,391.35 million barrels, though the exact data year is not specified.
  • Production peaked in 2015, and based on economic assumptions, it is expected to continue until the field reaches its economic limit in 2068. Currently, it accounts for about 3% of Kazakhstan's daily oil output.
• Offshore Kalamkas-Sea Field:
  • Estimated reserves include 81 million tons of recoverable oil and 22 billion cubic meters of recoverable gas.
  • The general reserves of hydrocarbons in the offshore field are estimated at 104 million tons, with 41 million tons being recoverable.

Geology

• The offshore Kalamkas-Sea field features several hydrocarbon reservoirs in the Jurassic section, starting from a depth of about 1,617 meters.
• The field is described as a long and narrow anticline, approximately 50 km long and up to 6 km wide.

Infrastructure and Development

• Onshore Field:
  • Mangistaumunaigaz AO uses advanced exploration technologies such as progressive cavity pumps and hydro fracturing.
• Offshore Kalamkas-Sea Field:
  • The field is in the front-end engineering design (FEED) stage, with the joint development project scheduled to run from 2022 to 2028.
  • The project involves significant investments of about $6.4 billion and is expected to create 2,000 new jobs during the design and development stage and 200 jobs during operation.

Partners and Agreements

• The offshore project involves PJSC Lukoil and JSC NC KazMunayGas as equal partners in the Kalamkas-Khazar Operating LLC.
• Other partners in the broader North Caspian Oil and Gas Project include ExxonMobil, Royal Dutch/Shell, Total, and ConocoPhillips, although their specific roles in the Kalamkas field may vary.

Current Status

• The onshore field is in continuous production since 1979 and is managed by Mangistaumunaigaz AO.
• The offshore Kalamkas-Sea field is in the development phase, with FEED currently in progress and expected to be completed by 2028.
