... and flows up the tubing, eliminating liquid buildup. For production surveillance, this wellbore configuration is not conducive to obtaining conventional production logs. Conventional production profiling techniques involve repositioning the tubing string or removing it altogether. If the tubing remains...

... Abstract The increasing demand for horizontal production logs is driving the use of all possible well-intervention technology approaches to fulfill technical diagnostic requirements and to acquire maximum logging coverage. Maximizing coverage will result in managing and exploiting the reservoir...
