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.

Systems and methods for cleaning an internal bore of a tubular member with a pipeline pig include a pipeline pig having a pig body with a fore end and an aft end opposite the fore end. A cup circumscribes the pig body, where an outer diameter lip of the cup engages a surface of the internal bore of the tubular member. A scraper assembly includes a scraper arm extending radially outward from the pig body and a spring biasing the scraper arm in a radially outward direction. A load cell is positioned to measure a movement of the scraper arm in a radially inward direction. A treatment trigger is actuated by a treatment signal from the load cell to deliver a treatment system to the internal bore of the tubular member, where the treatment signal is generated by the movement of the scraper arm in the radially inward direction.

Pipeline pig with retractable scraper

A method and a system for separating and recovering an entire liquid hydrocarbon sample using an accelerated solvent extractor is disclosed. In the method, a filter is inserted into a bottom portion of an extraction cell of the accelerated solvent extractor. An adsorbent is activated via heating in a furnace and then cooled. At least a portion of the adsorbent is then inserted into the extraction cell and a liquid hydrocarbon sample is introduced into the extraction cell on top of the adsorbent. The extraction cell comprising the sample is placed in a cell tray of the accelerated solvent extractor and the saturate, aromatics, and resins fractions of the sample are sequentially extracted using first, second and third solvents, respectively. The entire liquid hydrocarbon sample is extracted as a result of the method.
