The North Sea is a classic example of a mature hydrocarbon basin. Essentially stated, the large reserves are the easiest to find & are found first. As time goes on further discoveries are increasingly hard to find & at significantly higher cost.

Anyone who thinks that the North Sea will help give the #UK any energy security needs to do their homework (or could people calling for increased N Sea drilling just perhaps be playing politics?). #energy #hydrocarbons
