DrawWorks designs, manufactures, and sells circulating, fill-up and flow-back tools and systems for oilfield tubulars, including casing, tubing, and drill pipe. The company was founded in 2000 by Gus Mullins, an engineer with 40 years of experience with Schlumberger Well Testing, Baker Oil Tools, and Gus Mullins & Associates.

Who is DrawWorks?

While in his previous positions, Mullins designed drilling, completion, and surface equipment. Mullins also became highly knowledgeable in casing-to-tubing sealing technology, valve design, and the corrosion and erosion aspects of the drilling and completion environment. Armed with this knowledge and aware of both the strengths and weaknesses of existing circulating, fill-up and flow-back tools, Mullins determined to improve the offerings in this area by designing and selling products that are either superior to those currently on the market, such as the AutoFill and AutoValve, or entirely new to the industry, such as the DPC. Conveniently, all are simple to maintain and operate.

Q: What is the Relationship between DrawWorks, L.P. and DW Rentals & Service, L.P.?
A: Owned by the same partners, we are sister companies. DrawWorks, L.P. manufactures, engineers, and develops equipment for the rental equipment fleet at DW Rentals & Service, L.P.

Q: Can the AutoValve™ take flowback (returns)?
A: Yes, once inserted in the casing the AutoValve is fully opened and mud can flow in or out of the AutoValve. The AutoFill™ seal should also be stabbed in the casing when taking flowback.

Q: What does your SJC™ Single Joint Compensator do?
A: The SJC is used with a single joint elevator to balance a joint or stand of pipe while stabbing or removing it during tripping.

Q: How does the SJC differ from other systems?
A: The SJC is a pneumatically-operated system with a long, balanced stroke that reduces the possibility of damage to threads when stabbing or removing a stand or joint of pipe.

Q: How do you balance the pipe with an SJC?
A: Once the SJC operating pressure is set, no more is required of the crew.

Q: What are the rig requirements for using the SJC?
A: A minimum of 80 psi of rig air is required.

Q: What is the capacity of the SJC?
A: The SJC capacity is from 200 to 8,000 lbs.

Q: Do you provide the control panel?
A: Yes, there is a special control panel that has been designed to operate both the SJC and the DPC Drill Pipe Circulating and Flow-Back system.

Q: Do you provide slings?
A: Yes, we have slings for handling tubing, drill pipe or casing elevators.
