Profits at international oil companies are lower for a number of reasons. At Exxon the refining margins dropped 27% in 2007 compared to 2006. Cost for drilling, oil rigs and oil personnel are up sharply, and the production sharing agreements for Exxon in West Africa mean that the higher the oil price the less oil Exxon gets. The govenments of oil producing countries are taking a larger share of dollar coming from oil in their countries, and Exxon recently pulled out of Venezuela- the production at Exxon actually declined by 2% and at BP and Royal Dutch Shell by 4%. This decline will continue as the reserve replacement ratios of these oil companies are in a big decline as oil prices go higher. Most of the countries producing oil are renegotaiting their contracts at the first opportunity. Nigeria is about to do this, and even Alberta and the US government are doing this.
