... design includes the flare tower installed in the fore part, where the accelerations induced by the hull girder global vibrations are the highest. If the natural frequency of the flare tower is close to the natural frequency of the hull girder, significant flare vibrations might occur. In addition, spread...

Considering high frequencies used and proximity between electrodes, the tool provides very shallow measurements, which makes it impossible to evaluate the virgin zone in most reservoirs. Due to these characteristics, the tool was widely employed in low mobility hydrocarbon formations, where...
