Layoffs and inefficiency are far from the biggest risk Aramco and KSA face in he future. Continued low oil prices are a serious risk to the future economic stability of the KSA, a welfare state.
Aside from improving economic diversity, the Kingdom will be forced to go through serious social and economic reforms in the future to maintain its high social standards if oil prices remain low for long. I hope they can weather the coming storms.
The life blood of any country is revenue; the KSA currently needs $80/bbl oil to balance its budget. With world economic growth currently flat, OPEC and friends like Russia will need to cut production by 2-3 million bbls per day immediately to raise oil prices to this level, or wait for the world's economy to grow.
In North America, shale oil production from the Bakken and Eagle Ford will quickly come on stream if oil prices rise to $80 per bbl to buffer price increases and decrease US imports. North America, including Mexico, is becoming internal focused for their energy needs with large proven conventional, heavy and shale oil reserves at hand.
Conventional and shale oil production from Mexico will increase now that foreign companies are allowed to invest and own title to oil and gas reserves. President-Elect Trump has promised to give free rein to US oil and gas development in an attempt to make the US energy self sufficient. He plans to lower corporate taxes and remove barriers to increase pipeline infrastructure to lower transportation costs.
These developments will decrease the need for foreign oil imports in the US and North America. The US currently consumes 19.8 MMbbls per day and is a net importer of 4.7 MMbbls per day. It imports 1.1 MMbbls per day from the KSA.
