DETERMINING CASING FLUID CAPTURE CROSS SECTION USING GAMMA COUNT RATE RATIO
A method, in some embodiments, comprises lowering a neutron wireline tool into a cased borehole containing casing fluid, determining a ratio of inelastic count rate to capture count rate using gammas passing through the casing fluid, and calculating a capture cross section of the casing fluid using...

Un procédé, dans certains modes de réalisation, consiste à descendre un outil sur câble à neutrons dans un trou de forage tubé contenant du fluide de tubage, à déterminer un ratio entre le taux de comptage inélastique et le taux de comptage de capture à l'aide de rayons gamma traversant le fluide de tubage, et à calculer une section transversale de capture du fluide de tubage en utilisant ledit rapport. |
