COSL Completed a High-quality Workover Integrated Operation with a Semi-submersible Rig
China Oilfield Services Limited (“COSL” or the “Company”), has smoothly completed its first workover integrated operation with a semi-submersible rig, NH5 of the Company, in South China Sea waters. There were huge challenges for this workover operation stemming from the swinging trunk of the semi-submersible rig due to the winter monsoon in South China Sea. Guided by excellent environmental protection concepts, NH5 developed appropriate measures and cooperated closely with the partners and tackled difficulties in precision positioning of the equipment and seamless matching of the operation procedures. NH5 completed this workover operation smoothly, thereby established a solid foundation for the timely resumption of production of the well for the client. With this outstanding operation, NH5 has not only helped COSL generate revenue, but also won full recognition and endorsement with relevant praise from the client.
