Abstract:
A downhole tubular scraper is run in on slickline with an on board power supply. It features counter-rotating scrapers without an anchor in one embodiment or an anchor with single rotating scrapers. The scraper is selectively operated to conserve power in the power supply. A drive system uses a single driver to obtain counter-rotating motion in the scrapers.
