Brenntag-backed Coastal Chemical, a firm serving the upstream, midstream and downstream segments of the oil and gas industry, agreed to acquire Tech Management from Clearlake-backed Gravity, a provider of energy infrastructure services. Financial terms were not disclosed. "There is a strategic fit between Brenntag and Tech Management, and this sale allows Gravity to increase its efforts on its core, growth focused water logistics and power generation business lines for customers operating primarily in the Permian, the Bakken, and other key basins," José E. Feliciano and Colin Leonard, Clearlake Co-Founder and Managing Partner and Partner and Managing Director.
