20100265094 | FRACTURING MONITORING WITHIN A TREATMENT WELL - In some embodiments, a method includes receiving a data signal from a sensor that is positioned within a well bore, during a hydraulic fracturing operation. The method further comprising detecting a microseismic event, that is caused by the hydraulic fracturing operation, wherein the detecting comprises performing a noise canceling operation on the data signal. | 10-21-2010 |
20140114892 | APPARATUS AND METHODS OF ANALYSIS OF PIPE AND ANNULUS IN A WELLBORE - Various embodiments include apparatus and methods to provide pipe analysis, annulus analysis, or one or more combinations of pipe analysis and annulus analysis with respect to one or more pipes in a wellbore. The analysis can include application of clustering and classification methods with respect to the status and the environment of the one or more pipes in the wellbore. In various embodiments, the clustering and classification can be used in characterizing borehole annular material including cement bond quality evaluation. Additional apparatus, systems, and methods are disclosed. | 04-24-2014 |
