bore. The results have shown that the ERA measurement is an important component in the development of reliable reservoir formation data. It enables simultaneous measurement of flow rate, pressure, and resistance for better in-situ static and dynamic reservoir characterization - leading ultimately to maximized recovery of oil and gas resources in the region. "Innovative technology often results from collaboration. Saudi Aramco and Schlumberger have worked side by side in technology; we work seamlessly together, and we get results. We all stand to benefit from the application of FMM technology, and it is gratifying to have played a leading role in its development," explained Mohammed Qahtani, Manager of the Reservoir Description and Simulation Department at Saudi Aramco.
