RPS Group plc, an international consultancy and adviser to the natural resources sector, has channelled its latest capital spend into a niche business specialising in environmental monitoring and management for the energy industry.

The acquisition of US consultancy GeoCet Group from its founder directors went through for a maximum $2.3 million (£1.2 million) in cash. The initial consideration of $1.2 million (£600,000) was paid on completion, with the balance, comprising two equal payments, due in April 2009 and 2010 respectively.

GeoCet, together with its 29-strong staff, will be integrated with RPS’ existing energy business in the US. Its founding directors will remain with the business for a minimum of two years.

GeoCet provides environmental advice to the oil and gas and other industries from its offices in Houston, Texas. The company works with oil and gas exploration companies and government agencies writing and implementing protected species watch programmes during geophysical operations and marine construction projects, which has led to specialisation in environmental compliance and mitigation, including marine mammal observation.

RPS chairman Brook Land describes GeoCet as a niche business with an excellent reputation and anticipates the additional skill set will extend RPS’ client support offering in the oil and gas exploration and production sector.

Last year, GeoCet posted revenues of $4 million (£2.1million), profit before tax of $1.1 million (£600,000) and net assets of $300,000 (£160,000).
