DCM I wouldn't say it's true nowadays because technology has moved on and we have ways to get the oil through the bed, things like water injection and natural gas lift, this wasn't possible years ago so as soon as they lost pressure it will have been capped. There are also specialist companies who take over an ageing platform and upgrade it to get the last of the oil out and then decommission the platform, saying that some platforms are 60 years old. Bp etc are only interested in the initial boom of oil because it's easy they don't like to have to work for it because it costs money. Nowadays it's harder to extract it though and WI is used from the start. And the rigs get moved around to extract from different wells
