The important issue is not reserves over production (R/P). That is never the
case. RATE of production is everything. The fact is that we will be
producing oil 300 years from now but we will be producing insignificant
quantities of it. When a field comes on line it produces at it's maximum
rate for a short while (just how long depends on the field and how many
wells are put into it). But as the oil comes out of the ground, pressure in
the reservoir drops and the oil flows more slowly. The decline in the flow
rate is exponential. This means that it takes longer to get the oil out of
the ground than the initial R/P indicates. That is why people who calculate
how long oil will last by means of R/P are so wrong.
We do various things attempting to keep the flow up. We drill wells which
inject water into the field in order to replace the voidage of oil which has
been produced and to repressurize the field. But what happens in practice
is that the pressure comes up but we begin to produce more and more water.
In the North Sea we now produce 80-90% water and only 10% oil. The Forties
Field, here in the UK, produces 17 million gallons per day of water now,
about what Houston, Texas uses in a single day. Since the production pipes
into the ground have a fixed capacity if we fill it with mostely water
rather than oil, we get less oil out of the ground.
What the world faces is a drastic drop in the rate of oil production and an
inability to improve it.
