Since buying the club on July 1, 2003, Abramovich has overseen three Premier League titles - Chelsea's first since 1955 - as well as winning four FA Cups, two League Cups, the Champions League he so coveted and last season's Europa League.
And chief executive Gourlay said: "It has been a hugely successful decade for Chelsea Football Club since Roman Abramovich took control, with an unprecedented number of trophies in the last 10 years.
"The club has also taken great strides off the field in that time, adapting to meet the challenges of football's changing landscape.
"Mr Abramovich's early investment in playing staff paid dividends in creating a team admired around the world, but to keep Chelsea among the elite we have always known we must produce our own world-class talent and we are beginning to see the benefits of our Academy, which will help us meet our long-term objectives for Financial Fair Play.
"As we prepare for the next 10 years, I feel we are well positioned to continue the success we have so far enjoyed under Mr Abramovich and everybody here is determined to build on that progress we have made."
