The contract has two two-year extension options and comes in addition to AGR's 45 consultancy clients in more than 40 locations worldwide.
Earlier this year, the company signed frame agreements with several other major operators on the Norwegian Continental Shelf.
"We are very pleased to secure this important frame agreement," AGR Consultancy Norway manager Thomas Veseth Saue said.
"The consultancy division is an important part of what AGR is offering from the Stavanger office, along with our well management, health, safety, environment and quality, reservoir and training services."
