THE CHOICE OF OPTIMAL TECHNOLOGY OF MEASUREMENT AND PROCESSING OF BOREHOLE ACOUSTIC DATA IN OPEN AND CASED WELLS
(Shubin A.V. Gorodnov A.V. Chernoglazov V.N. Ryzhkov V.I. Dobrynin S.V. Logovskoi V.I. )
The article presents the results of a comparative analysis of the tools and processing algorithms used for borehole sonic. The authors have studied acoustic data obtained in the same wells (both open and cased) by the following manufacturers: XMAC («Baker Hughes»), Sonic Scanner and DSI («Schlumberger»), MPAL («CPL», China), AVAK-11 («Neftegazgeofizika», Tver, Russia). The processing results done by service companies and by authors have been analyzed. Data quality assessment was conducted on the basis of integrated interpretation of log and core data and rock physics modeling.......
