Paper presented at the IADC/SPE International Drilling Conference and Exhibition, March 5–7, 2024
Paper Number: SPE-217705-MS
..., thereby stopping further fluid losses. TALCMs can be employed as additives in drilling fluids, in dedicated treatment pills, or mixed with cement for dedicated squeezes. TALCMs are a new type of temperature-tunable material that can be engineered to mitigate severe losses in a variety of geological...

...-in. outside diameter (OD) window. Despite never having performed an installation in this size of expandable liner, the provider had a run history for exits with similar modifications and extra trips to enlarge and elongate windows. Job challenges included thin-wall, channeled cement; limited flow rates...

... The concept, presented in this paper, relies on the experience of utilizing passive noise recordings and spectral analysis to determine active flow through cement barrier defects ( Maslennikova Y, 2012 ). It aims to show that spectral noise logging (SNL) is effective when there are minor defects...
