The success of field management depends on the accuracy and availability of well performance data. Continuous monitoring provides information so that corrective action can be taken in a timely manner to better manage expensive well assets by maintaining well potential, managing water conformance and increasing the well life. Accurate water-cut monitoring can significantly reduce the dead well number by providing the data to implement timely corrective action. Methods for measuring water-cut values range from conventional hand sampling to cutting edge technology. Saudi Aramco's traditional well testing practices, utilizing a test trap at a GOSP, limit the information available due to the infrequent tests for an individual well, usually exceeding one month or more. Test trap data also has inherent error built in, due to averaging and human error. What is needed is real-time, in-line and accurate water-cut monitoring. When considering technologies for monitoring watercut, factors such as accuracy, data transfer rate, and cost play major roles. This paper presents how an infrared meter provides an accurate and cost effective means to monitor water-cut in complex wells. The infrared monitoring device is an in-line real-time monitoring system that provides accurate water-cut even, in very challenging flow conditions. A pilot test of the infrared water-cut meter was successfully conducted in a major oil field in Saudi Arabia. Results from this test will be included in the paper. |
