Wood Group's growth in US onshore shale work

A round-up of Wood Group's growth in US onshore shale work

Approximately 2,500 employees supporting contracts in US shale fields

HOUSTON, September 4, 2013- Wood Group's activities to support oil & gas
production from shale fields in the US are growing, with annualized revenue
totaling approximately $500 million. This growth supports our outlook for 2013
shale activities and is being driven primarily by two of Wood Group's
businesses. Together, Wood Group Mustang and Wood Group PSN have around 2,500
personnel providing engineering, operations & maintenance services to US shale
fields.

Wood Group Mustang has supported more than 110 shale projects. Its first
project in what is now a major shale play was a 1995 process study that
examined ways to improve the efficiency and operation of a natural gas liquids
plant in the North Dakota section of the Bakken shale play. Wood Group Mustang
now has around 600 employees supporting shale projects, which include:

gathering pipelines, compressor stations, pump stations, measuring facilities
and other midstream facilities in a number of the US shale plays;

multi-well pad designs in the Eagle Ford, Marcellus, Utica and Bakken shales;

front-end engineering design (FEED) and detailed design for a 250 million
standard cubic feet/day cryogenic turbo-expander gas plant in the Bakken;

greenfield and brownfield engineering services for a gas plant expansion
program; and

automating a chemical injection system for wells in the Eagle Ford.

Wood Group Mustang's shale-related work is performed at four locations in the
US; and in Calgary, Canada; and Bogota, Colombia.

Wood Group PSN, specialists in brownfield production services, increased its
presence in the US shale markets in 2012 with the acquisitions of Duval and
Mitchell's, in the Eagle Ford and Bakken shale regions, respectively.
Delivering operations & maintenance, construction, training & development
programs, and consulting services, Wood Group PSN now employs 1,900 people
across the US shale market.

"Shale production is significantly changing the global energy market," stated
Bob Keiller, CEO of Wood Group. "Wood Group has the knowledge and experience to
support our customers as they increase their focus on shale regions worldwide."
