... behaviour to predict stress-strain distributions around the borehole. A set of hollow cylinder experiments was then conducted under different compression scenarios and 3D X-Ray Computed Tomography was performed to analyse the internal structural damage. The results of the proposed analytical solutions were...

Paper Number: SPE-176186-MS
... (GP) logging is a technique traditionally used to evaluate the quality of the gravel distribution in a gravel pack. The measurement is sensitive to silicon around the borehole, hence a technique was adapted to detect sand blockage in the wellbore by logging the pulsed neutron tool inside the tubing...

Paper Number: SPE-158160-MS
... Abstract The measurement of actual wellbore shape in real-time can be considered as one of the key components to detect problems such as borehole instability. Abnormal wellbore shape will allow drawing conclusions on the stress field and the impact on other sensors' responses as part of LWD...
