Overview of the Rumaila Oil Field in Iraq
The Rumaila Oil Field in Iraq is one of the largest oil fields in the world, and it has been a significant source of oil production for Iraq for many years. Located in the southern part of the country, near the border with Kuwait, the field covers an area of approximately 1,800 square kilometers. It is estimated to hold around 17 billion barrels of oil reserves, making it a highly valuable asset for the Iraqi economy. The development of the Rumaila Oil Field began in the 1950s, when the Iraq Petroleum Company (IPC) discovered oil in the area. Production started in 1954, and since then, the field has undergone several phases of development to increase its output. Today, it is operated by the Rumaila Operating Organization (ROO), a joint venture between the state-owned Iraq National Oil Company (INOC), BP, and the china National Petroleum Corporation (CNPC). The oil field is divided into three main zones: North Rumaila, Central Rumaila, and South Rumaila. Each zone has its own set of wells and infrastructure, but they all contribute to the overall production of the field. The North Rumaila zone is the largest and most productive, accounting for about 60% of the field’s total output. The Central and South zones, although smaller in size, still play a significant role in the field’s production.Labels | Outside Diameter (d/mm) | T&C (kg/m) | Wall thickness (t/mm) | Type of end-finish | |||||||
