DrawWorks designs, manufactures, and sells a family of circulating, fill-up, and flow-back tools for oilfield tubulars, including casing, tubing, and drill pipe. DrawWorks products are designed to reduce risk and save time by simplifying two key drilling processes: running tubulars and handling fluids. DrawWorks' family of products includes the AutoFill™ Casing Fill-Up and Circulating System, the AutoValve™ Mudsaver Valve, the DPC™ Drill Pipe Circulating and Flow-Back System, the SJC™ Single Joint Compensator, and lightweight Drift Bars. We have over 50 years of experience in research and design of "down hole tools". We are very knowledgeable in valve and seal technology, and we are in our third generation of improvement for some of our products. We use the latest technology in Computer-Aided Design, including FEA and flow analysis.
