A company with roots back to Oklahoma’s statehood is using its experience in the oil and natural gas business to keep up with the industry’s latest trends.

Lee C. Moore, a Woolslayer Co., has designed a new drilling rig structure to meet the needs of companies working throughout North America.

CEO Tom Wingerter acknowledged the industry is moving toward more pad drilling, but operators still need to be able to move rigs quickly between sites. He said the Tulsa-based company’s design offers the best of both worlds.

Lee C. Moore’s HMR SlotBox rig structure can walk between well bores on hydraulic feet, while the entire box and mast can be packed up into seven truck loads for easy transport.

Wingerter said the company expects to be issued a patent on its latest design later this month.

Lee C. Moore has been in business since 1907. The company displayed the first cantilever at the 1938 International Petroleum Exposition in Tulsa, where the design quickly was accepted throughout the industry.

Wingerter said the company has focused on its specialties of structural design and fabrication.

“We still use parts and pieces from the 1930s and we innovate from there,” he said. The company has manufactured more than 4,000 cantilever structures and 600 offshore derricks at its facilities at the Port of Catoosa. The company worked with Chesapeake Energy Corp. subsidiary Nomac Drilling, which is the fourth- most active drilling contractor in the U.S., to develop the rig structure.
