Actually, according to commentary on the news last night, the big drop in oil price is not because of oversupply - supply and consumption are pretty closely in balance - but because speculators expect prices to drop sharply because oversupply is expected.
This is probably a little harsh, as a lot of these "speculators" are probably big users who have for years locked in prices under forward contracts, but because they expect prices to drop are not signing more forward contracts, pushing a lot more oil onto the open market, depressing the price of oil traded on the open market (which of course is where the quoted prices come from).
The reality is that oil consumption is, in the short term, very inelastic to changes in price, so drops in price do not see a big increase in consumption, but in general, neither is production very dependent on price in the short term.
Long term (>5 years), oil price changes will change the amount of production available, but in the short term won'[t have much effect. With the exception of some tertiary recovery projects, the major cost of production is capital (exploration and production infrastructure) - and for existing fields, this has mostly already been spent. Lower oil prices mean the venture is no longer economically viable - but as long as the incremental production pays above running costs, the production will probably continue, even if the bank that lent the money forecloses and sells the property for a fraction of what it owed. Similar projects won't get off the ground, but this won't affect production for several years.
Production capacity and reserves are probably the highest they have ever been, but high prices for the last decade and economic stress have led to large scale increases in energy efficiency worldwide, so that demand is likely to drop significantly below capacity despite increasing industrialisation and rising living standards, particularly in India and China. The resulting drop in price will lead to another shortage situation, but this is expected to not be for another ten years or more - simply because of the lag between price signals and new production becoming available.
