A Scottish oil and gas ­consultancy is on course to grow turnover 50% this year after ­capitalising on a big increase in spending on new developments in areas like the North Sea.

Aberdeen-based ADIL expects to increase sales to £31 million in 2013, from £20m last year after enjoying strong growth in the first half of the year.

The privately owned company's success provides another example of how booming investment by oil and gas firms in new facilities off Scotland is fuelling strong demand for services across the supply chain.

Founded in 2006, as Asset ­Development and Improvement Limited, the company provides services ranging from helping oil and gas firms plan drilling campaigns, to advising them on commercial strategies.

The company says it is providing field development services for projects that will involve in excess of £2.5 billion investment. Around 75% of turnover recorded this year has been generated in the UK.

The company has people based in Norway, Dubai, Korea and China. It has been involved in other projects in Denmark, Tunisia and Ireland. The success had led to the company creating a significant number of high-value jobs.

ADIL increased employee numbers to 162 at July 31, from 109 at the same point last year. It also opened an office in London.

A spokesman for the company said ADIL intends to continue with "reasonably heavy recruitment activity" to the end of 2013.

The company has strengthened its board to help maintain growth.

John Moody has been appointed commercial director with a brief that includes overseeing the development of new business products for the oil and gas industry.

Mr Moody joined ADIL as general manager in 2010, following a 28-year career with Conoco­Phillips. James Paton, managing director of ADIL, said: "John's considerable commercial experience will be invaluable to us."

He added: "We have already experienced major growth in the past few years and we are confident his appointment will see this continue."

Mike Fuery has been appointed general manager. He joined ADIL in 2011 as developments consultancy manager following 28 years at Shell.

ADIL said David Raeside has been recruited as commercial manager after holding senior roles with the ASCO, KCA Deutag and Sparrows Group oil services operations.

The company had £13.8m ­turnover in 2011.
