... and ongoing hole enlargement and thus the method has shown a new application. Further work linking PTR and T 2 distribution to sedimentary features observed on scanning electron microscopy energy dispersive spectroscopy (SEM-EDS) is required to fully understand the pore space system and thus determine...

.... They are equally useful for diagnosing operations issues, for example by identifying loss zones, investigating wellbore enlargement and creating pseudo calipers for cementing calculations. The paper will demonstrate that the total value which can be delivered from time lapse LWD far exceeds that derived from...

Paper presented at the SPWLA 31st Annual Logging Symposium, June 24–27, 1990
Paper Number: SPWLA-1990-G
... ABSTRACT Formation density measurements made while drilling can be adversely affected if the hole becomes enlarged before the density measurement is made. This can occur even if a stabilizer is used to exclude mud from in front of the source and sensor windows. The position of the rotating...
