Tang-e-Bijar & Kamankuh Gas Field Development – Second Phase
Overview
The Tang-e-Bijar and Kamankuh gas fields are major energy resources located in the Zagros Mountains in the western region of Iran. These fields are strategically positioned about 125 kilometers from Kermanshah and 60 kilometers from Ilam. Both gas fields are currently in production, providing a critical supply of natural gas to various parts of the western provinces of Iran.
The gas produced from these fields is classified as sour gas due to its high content of CO₂ and H₂S. In addition, the formation water associated with production contains a significant concentration of chloride (Cl⁻) ions. Production wells are widely spaced, typically around 15 kilometers apart.
Current Production Phase
Wells
Currently, natural gas is being extracted from five wells: No. 3, 5, 8, 9, and 11.
Processing Operations
Tang-e-Bijar Central Facility (TCF):
Incoming gas, gas condensate, and water are initially separated in a slug catcher.
The separated gas is transported to the ISF facilities via an 18-inch pipeline covering a distance of 40 kilometers.
Gas condensate passes through a three-phase separator for further water removal before being sent to ISF through a 6-inch pipeline.
ISF Facilities:
Gas received from TCF enters a slug catcher at ISF, where any remaining liquids are separated.
The final processed gas is delivered to the Ilam Refinery for further treatment and use.
Project Objectives
Due to several recent incidents, including accidents and explosions at the TCF, the project’s main objective is to enhance both safety and operational efficiency in the following key areas:
Flow Lines from Wells to TCF:
Assess and troubleshoot the existing gas and oil flow infrastructure.
TCF Facilities:
Improve safety standards and optimize the separation and handling of gas and condensate.
Gas Transmission Pipeline (TCF to ISF):
Evaluate the integrity and capacity of the 18-inch pipeline used for gas transmission between TCF and ISF.
ISF Facilities:
Enhance the processing of gas and condensate received from TCF, ensuring safe and efficient operations.
Future Expansion Plans
To support the growing demand for energy and to increase natural gas and condensate output, the project will move into a new phase that includes:
Integrating three additional production wells to boost total gas capacity to 10 MMSCMD.
Re-evaluating Flow Lines:
Updating and adapting current infrastructure to accommodate higher volumes from new wells.
Enhancing TCF Facilities:
Upgrading facility systems to manage increased production of both gas and condensate.
Upgrading Gas/Condensate Pipelines:
Ensuring pipelines can support the new, higher transmission capacity.
Improving ISF Facilities:
Expanding and upgrading ISF capabilities for efficient processing of the additional gas and oil flow.
Deliverables
Basic Engineering Package:
Preparation of a comprehensive, detailed engineering package to support all next-phase development activities, ensuring best practices in gas and oil field development for the western Iran region.
