Paper: Sucker Rod Type Paraffin Scrapers

Paraffin Accumulation in the tubing of pumping oil wells has been a costly problem since the beginning of the oil industry. Some fields have a severe paraffin problem while others do not have enough paraffin accumulation to ever restrict the production of the wells. Each field has a different paraffin problem all its own. The accepted use of sucker rod type paraffin scrapers to remove paraffin from pumping oil wells is relatively new to the industry. Sucker rod type paraffin scrapers became popular between 1946 and 1950.
