Why I belong to the National Drilling Association:

"Despite the distance between Kuwait and the U.S., our membership as a contractor with NDA has opened the gate of knowledge and technology for INCO-LABS. Since INCO-LABS joined NDA, the communication and information exchange became smooth and easy with drilling rigs manufacturers and other testing instruments providers. Moreover, INCO-LABS has improved its HSE management system with the help of NDA safety tips and driller safety guide provided by NDA. Thank you NDA for your continuous support, we will support you as a member at all times."
