Chief executive Graeme Coutts has moved up to become executive chairman of international oilfield service company Expro.
Chief operating officer Gavin Prise is the new chief executive of the firm, which employs about 700 people in Aberdeen.
The changes came as Expro prepares for the next stage of its development.
The £1.81billion sale of the company to private-equity interests went through last July and led to its London-listed shares being cancelled.
The consortium made up of Candover, Goldman Sachs Capital Partners and AlpInvest Partners was successful in its move for the company, despite interest from US giant Halliburton.
Reading-based Expro has a global workforce of 5,000 people in 50 countries.
Under yesterday’s management changes at the firm, non-executive chairman Peter Goode – who works for Candover – becomes a non-executive director.
Expro said his industry experience and leadership qualities had been instrumental in the smooth transition of Expro to private ownership.
Mr Coutts, who had been chief executive since 2003 and is in his 20th year with Expro, said: “Despite the more challenging business environment in 2009, Expro has successfully and smoothly transitioned to private ownership under the experience and guidance of our owners.
“This process has been achieved without any disruption to strategy or performance, and I must thank Peter Goode for his role in the transition.
“For the past three years Gavin Prise has been my chief operating officer and an outstanding member of my executive team.
“Expro’s success has been due, in no small part, to Gavin’s efforts and input and his promotion to CEO is richly deserved.
“I continue to see a very bright future for Expro in a world where fundamental hydrocarbon energy supply challenges continue to increase.
“Therefore, these executive changes are designed to create increased focus on our strategic objectives. Furthermore, these changes serve to demonstrate the depth of management talent within the company.”
Mr Coutts described the private-equity consortium which owns Expro as long-term and very good investors in the business.
