AFES January Talk - Chee Kong Chen from Baker Hughes

Abstract:

Operators often conduct well entries in a well for various purposes, like replacing valves or setting plugs. These well entries present opportunities for data collection for better well surveillance.

In this case history, we present a case where a multifinger-caliper tool (MFC) was run to understand tubing integrity during a DSIV replacement operation in a water injector for a UK North Sea operator. While the MFC data did not show significant integrity issue for the majority of the tubing, a closer examination of the temperature data showed an unusual temperature trend around the wireline entry guide (WEG) of the tubing.

Analysis indicated the potential for crossflow between the reservoir and overburden zones. A further production logging (PLT) survey was planned to confirm the crossflow/leaks and injection profile. The information resulted in a change in operating procedure for the well.
