Running a mature old field is perhaps like keeping your father in law's farmhouse maintained as he gets old. You don't know where he keeps everything, every task needs specialist skills and specialist items, you have systems developed by people who are long gone, some relationships are important but you don't know which ones. These are not traditional oilfield skills and processes. But this is what we need to master to get the most out of our older fields. Finding Petroleum shares best ideas about how to do it.
