BP has awarded contracts in the area of application development and maintenance to IBM, Accenture, and three Indian outsourcers.
The oil giant had been outsourcing these services to 40 service providers, and decided to rationalise the number to five, a BP spokeswoman said on Wednesday.
The five providers selected were already offering services to BP, she added.
The total contract value is £1.5 billion over five years, which was 500 million pounds lower than BP had budgeted for the contract.
IBM and the three Indian outsourcers -- Wipro, Infosys Technologies, and Tata Consultancy Services --said separately on Wednesday that they had been selected by BP for five-year contracts, for an undisclosed amount.
IBM said it had bagged the largest among the contracts awarded by BP at the end of a 12 month programme to consolidate its application development and maintenance vendors. The BP spokeswoman declined to discuss the share of each vendor in the total contract value.
Like its Indian competitors, IBM is likely to deliver a significant portion of the work for BP from its Indian operations.
Indian outsourcers have around 40 percent of the global market for outsourced application development and maintenance services, Siddharth Pai, a partner at outsourcing consultancy, Technology Partners International (TPI), said on Wednesday.
