Shell has signed a five-year deal with CGI to support the oil giant's Technical and Competitive IT (TaCIT) unit, which is responsible for providing services across a number of the company's key portfolios.

CGI acquired Logica, one of the UK's largest outsourcing companies, in May last year for an estimated £1.7 billion.

As Shell's lead key application services supplier, it will support TaCIT's critical business and technical applications in three business areas:

"Shell is a leader in developing innovative solutions in the energy industry, and its TaCIT team is key in delivering a vast range of applications and technology capabilities to meet the needs of both its upstream and downstream businesses," said Tim Gregory, president of CGI's UK operations and executive sponsor of CGI's relationship with Shell.

"In our role as a global key application services supplier we will work with Shell TaCIT to enhance their industry position with the right solutions."

CGI will deliver projects and managed services to support Shell globally from four of its primary locations: the UK, North America, the Netherlands and India.
