Shell is to pay $1m (£522,000) to the ex-finance chief who stepped down from her post in April 2004 after the firm over-stated its reserves.
The scandal rocked investor confidence
Judy Boynton finally left the firm on 31 December, having spent the intervening time as a special advisor to chief executive Jeroen van der Veer.
In January 2004, Shell told shocked investors that its reserves were 20% smaller than previously thought.
Shell said the pay-off was in line with Ms Boynton's contract.
She was leaving "by mutual agreement to pursue other career opportunities", the firm said in a statement.
The severance package means she keeps long-term share options, but fails to collect on a 2003 incentive plan since the firm has failed to meet the targets included in it.
The revelation that Shell had inflated its reserves led to the resignation of its chairman, Sir Phil Watts, and production chief Walter van der Vijver.
An investigation commissioned by Shell found that Ms Boynton had to share responsibility for the company's behaviour.
Judy Boynton has been helping with "special projects" since April
Despite receiving an email from Mr Van de Vijver which said the firm had "fooled" the market about its reserves, the investigation said, she did nothing to inquire further.
In all, Shell restated its reserves four times during 2003.
In September, it paid £82.7m in fines to regulators on both sides of the Atlantic for violating market rules in its reporting of its reserves.
