Abstract
A system for surveying internal pipeline scaling includes a control system, a gauge cutter, a scale recorder, and a wireline. The control system communicates with the scale recorder to obtain scale recorder data and acoustic images. The gauge cutter dislodges scaling debris from an interior wall of the pipeline and includes a fluid permeable screen which collects the dislodged scaling debris. The scale recorder obtains scale recorder data and acoustic images, and includes an ultrasound wave transmitter, an ultrasound wave receiver, a processor, a memory, and a communication interface. The wireline lowers the gauge cutter in the pipeline and is coupled to the control system and the communication interface.
