A modified coiled-tubing-conveyed production logging string proved effective for obtaining logs in a short-radius horizontal well in Saudi Arabia’s Ghawar field. The job used a Baker Atlas Polaris ...

Production logging (PLT) determines where, how, and how much each interval in a completed oil well contributes to total well flow in real time under producing conditions. Key outcome: a depth-by-depth ...

Well logging is the practice of recording and analyzing various kinds of data about the rock formations around a borehole during or after drilling. Also called borehole logging, this activity aims to ...

Guidance and recommendations for radiation protection and safety in well logging – the study of geological formations penetrated via a borehole – and accelerator-based radioisotope production are ...

Production logging determines where, how, and how much each interval of a completed well contributes to total flow under actual producing conditions. It diagnoses zonal contributions, crossflow, phase ...
