Spartan Energy Partners, which owns and operates gas facilities, agreed to acquire a 23% stake in CSI Compressco, a provider of compression services and equipment for natural gas and oil production, from TETRA Technologies, a geographically diversified oil and gas services company, for $31m. "The TETRA Board and management team continue to focus on taking the necessary actions to unlock shareholder value. TETRA continues to perform well in difficult market conditions, but the consolidated debt of CSI Compressco has represented an overhang and limited the transparency of TETRA's financial position. Following our divestment of CSI Compressco's general partner, the Company will focus on our capital efficient business model that has continued to generate positive free cash flow throughout the cycles, including one of the worst our industry has ever experienced in 2020 due to Covid-19," TETRA Brady Murphy President and CEO.
