hedging is a useful tool to protect your bottom line. A bit like you need to buy car insurance or home insurance etc to protect you. As no one can predict what future holds with confidence, the hedge is always the good practice. I recalled Meg mentioned sometimes ago, Wds hedges some portion of product, 10-20%, to prevent from sharp movement of price movements.The long term of Brent price, which Wds used for each project for sale of oil & gas, is kind of hedge as well. So long, they don’t over commit too much production volume, It would make proj development or deployment of capitals more predictable.
