Karun Oil and Gas Company has initiated a project to construct two oil transfer pipelines from the eastern section of the Karun River to the Ab-Timor operation unit, with the aim of increasing oil production capacity. This project includes two 10-inch pipelines, each 3.5 kilometers long, designed to transfer oil from the wells in this section to the operation unit.
Technical Details of the Project
Afshin Arya, Engineering and Construction Manager at the National Iranian South Oilfields Company, explained that due to the necessity of crossing the pipelines under the Karun River, directional horizontal drilling (HDD) technology has been utilized. For each pipeline, 700 meters of drilling has been conducted, totaling 1,400 meters drilled to a depth of 30 meters below the river surface while adhering to safety requirements.

Advantages of Directional Horizontal Drilling Technology
Arya continued that directional horizontal drilling is recognized as a specialized method for implementing pipelines in areas with natural obstacles. This technology allows pipelines to cross under rivers without the need for open excavation, thereby reducing direct interventions in the environment and providing safe and engineered project execution conditions.
This project also includes conducting geotechnical studies, preparing and leveling the route, constructing access roads, performing operations to cross under roads, and implementing cathodic protection systems, as well as providing electricity and installing lighting equipment.
Quality Control and Execution Stages
The Engineering and Construction Manager at the National Iranian South Oilfields Company identified the execution of pigging and hydrostatic tests as key stages in quality control and ensuring the integrity and readiness of the pipelines for operation. Upon completion of this project, the necessary infrastructure for transferring oil from the wells in the eastern section of the Karun River to the Ab-Timor operation unit will be established, enabling an increase in production capacity up to 10,000 barrels per day at Karun Oil and Gas Company.
