The long-term oil price forecasts are very diverse, owing to the high level of uncertainness on a range of crucial elements.

At a the last summit of aficionados in Russia that illustrates the wide range in estimates even just for local supplied crude the Russian Ministry of Energy, or Minenergo, the "official" government estimate has oil prices low - at about $80 a barrel in 2013.
However, there were other estimations put in front. The Ministry of Finance (MinFin) set up what can only be described as a slump approach. This estimate puts oil prices at $62-$65 a barrel.
Then there is the Ministry of Economic Development (MED). MED considered both domestic and external trade considerations. The estimate coming from this ministry was lower than that of Minenergo, but at $75 a barrel was higher than that of MinFin.
Against this backdrop of different forecasts made by conflicting Russian ministries, estimates from the outside including many are also varied but many are tending to the upside.
Granted, all of the non-Russian suggestions cite the three unknowns limiting the cost of crude elsewhere: the fiscal cliff, the Eurozone debt crisis, and the expected levels of productivity and demand coming from China.
A strong consensus did emerge from North American and European experts it will rise
The overwhelming view is that oil prices will be moving very high next year, although the continuing volatility will guarantee that this is hardly going to be a straight line progress.
Even still, there will be a number of grounds that will push Brent and WTI prices as much as 20% higher next year-particularly in the first quarter.
2013 Oil Price Forecast: Oil Prices Are Set to Rise
On the European scene, The aspiration observed in Frankfurt and Warsaw a few weeks ago was more pronounced in Moscow among the Europeans there.
Not a soul believes the weakness in the continental economy will be disappearing anytime soon. But the stark anxieties of a collapse in the Eurozone, so much a staple of the talking heads on media throughout much of 2012, is simply absent as we move into the new year.
As for China, we must agreed that this has been consistent and is not causing the massive fluctuations predicted.
The Chinese economy has "cooled" to an annual rise in excess of 7%. The growing demand level is still there and so is the influence level expected from a quickly expanding Chinese middle class.
These three elements, therefore, are converging in a way to give a result of higher crude prices. All of them are on the demand side of the equation. As each improves, so also will the projections for oil and oil product volume.
Inventory Fundamentals Will Drive Oil Prices Upward
On the sources side, we continue to witness rising costs in both mainstream and alternative crude production.
This development largely results from the smaller fields, inferior quality crude, and accelerating infrastructure expenses associated with drilling. Coupled with these are the ever-present geopolitical struggles in the Persian Gulf, Syria and North Africa.
These considerations translate into higher crude prices .
Should the Iranian circumstance deteriorate, or the standoff between Iraqi central forces and Kurdish provisional militia , the situation in the Persian Gulf alone would add a risk premium to both benchmarks as well.
Most Indicators for the coming year are pointing to a rise with inherent fluctuations but consumers tend only to experience the rises not any short term decreases
