This paper describes a set of tools that allows a developer to instrument a C/C++ program to log data at run-time and then analyze that data to verify correct behavior. The logging tools provide the developer with a means to log a variety of di erent data to a variety of di erent outputs. They also allow for synchronized logging of data from distributed programs. One logging output option is an...

Nowadays, due to the increased user requirements of the fast and reliable data management operation for mobile applications, major device vendors use embedded DBMS for their mobile devices such as MP3 players, mobile phones, digital cameras and PDAs. However, database logging is the major bottleneck against the fast response time. There has been a lot of work minimizing logging overhead but no ...

One of the crucial steps geological object exploration is interwell correlation. The correlation matches similar parts different wells helping to construct models and assess hydrocarbon reserves. Today, a detailed relies on manual analysis well-logging data: process prone significant time consumption subjectivity. Alternative automation attempts include rule-based, classic machine learning, mor...

-This paper based on crossplot and core data,analysis the Pu Xi oilfield ,Putao Hua oil layer ‘s conventional logging response characteristic.Based on the describe of the three cored wells, Putao Hua oil layer is mainly made up with siltstone, muddy siltstone, silty mudstone,. First normalized the well logging curves, elimination the influence of the nongeological factors to the well logging cu...
