Well Integrity Evaluation with LWD – Quantitative Full Range Cement Bond Index
Available to PurchaseYan Wei Feng, Nick Robinson, Wataru Izuhara, Hiroaki Yamamoto, Shim Yen Han, Yu Guan Cheng, Mu Zhu Lin, Shi Wen Zhuan, Jiao Ming
Paper presented at the SPWLA 22nd Formation Evaluation Symposium of Japan, September 29–30, 2016
Paper Number: SPWLA-JFES-2016-G
... Abstract This paper discusses well integrity evaluation using LWD sonic monopole data. The first part of the paper explains the methodology which enables full range cement bond index determination i.e. 0 to 1; a hybrid method which uses both amplitude and attenuation through a receiver array...

Dispersion Characteristics of Leaky Compressional Mode With LWD Sonic Tool
Available to Purchase
Paper presented at the SPWLA 19th Formation Evaluation Symposium of Japan, September 26–27, 2013
Paper Number: SPWLA-JFES-2013-FF
... sonic tool in 12.25 inch borehole, the dispersive part tends to become invisible due to high attenuation. The presence of the tool also has a strong influence on the slowness dispersion and attenuation. This paper evaluates the effect of those factors and their implications on the sonic tool design...
