GOWell Petro introduced its latest generation array-noise tool (ANT) for deployment on electric line or slickline. GOWell’s ANT tool is a leak-detection technology that uses high-sensitivity acoustic sensors packaged within a 111/16-in.-outer-diameter wireline tool. The combination of a vertical array of differential acoustic measurements when coupled with advanced processing provides sensitive leak detection while logging. Rejection of unwanted road noise has typically been a major challenge with noise logging, which has only been solved by taking stationary measurements. However, the design features of the ANT overcome this limitation and provide an enhanced ability to detect leaks and other downhole noise sources such as completion anomalies or reservoir behavior. When the ANT noise tool is combined with GOWell’s Magnetic Thickness Detector (MTD) electromagnetic pipe-inspection tool, a comprehensive leak evaluation is possible. The MTD identifies the location of pipe connections in multiple casing strings and other completion items that can be prone to leaking. The ANT tool can be run alone or, when combined with a range of well-integrity or production-logging tools, can provide comprehensive diagnostics of well problems.
