Tetra Technologies has completed the acquisition of Greywolf Production Systems for US $55.5 million in cash, effective July 31.

The acquisition was funded with a combination of available cash and borrowings under the company’s revolving credit facility.

Greywolf is a well testing and flow back company headquartered near Calgary, Alberta, with Canadian operational centers in Crossfield and Grande Prairie, Alberta, and US operational centers in Williston, North Dakota, and Shoshoni, Wyoming.

“We are eager to continue working with the Greywolf team to begin the process of merging our production testing operations, and we are excited to commence the introduction of our expanded service capabilities to both new and existing customers,” said Stuart Brightman, Tetra’s president and CEO.
