... of conventional logs. To identify the characteristics of good connectivity reservoirs, advanced logging while drilling (LWD) electrical image data and modular formation dynamic tester (MDT) data were integrated, and the controlling factors were investigated. First, based on LWD electrical image data as well...

... ABSTRACT In the current scenario of project management, where the agility and optimization of operations has been prioritized, the practice of logging while drilling has gained space compared to traditional wireline logging. In theory, acquiring quality petrophysical properties during drilling...
