Saudi Aramco reveals sharp output drop at its major fields
When Saudi Aramco on Monday published its first ever profit figures since its nationalization nearly 40 years ago, it also lifted the veil of secrecy around its mega oil fields. The company’s bond prospectus revealed that Ghawar is able to pump a maximum of 3.8 MMbpd―well below the more than 5 MMbpd that had become conventional wisdom in the market.
The Energy Information Administration, a U.S. government body that provides statistical information and often is used as a benchmark by the oil market, listed Ghawar’s production capacity at 5.8 MMbpd in 2017. Aramco, in a presentation in Washington in 2004 also said the field was pumping more than 5 MMbpd and had been doing so since at least the previous decade.
The new maximum production rate for Ghawar means that the Permian in the U.S., which pumped 4.1 MMbpd last month according to government data, is already the largest oil production basin. The comparison isn’t exact―the Saudi field is a conventional reservoir, while the Permian is an unconventional shale, formation―yet it shows the shifting balance of power in the market.
Safaniyah, found in 1951 and still today the world’s largest offshore oil field with capacity of 1.3 MMbpd. In total, Aramco operates 101 oilfields.
Saudi Aramco is able to pump a maximum of 12 MMbpd―as Riyadh has said for several years. The kingdom has access to another 500,000 bpd of output capacity in the so-called neutral zone shared with Kuwait.
While the prospectus confirmed the overall maximum production capacity, the split among fields is different to what the market had assumed. As a policy, Saudi Arabia keeps about 1 MMbpd to 2 MMbpd of its capacity in reserve, using it only during wars, disruptions elsewhere or unusually strong demand.
Aramco also disclosed reserves at its top-five fields, revealing that some of them have a shorter lifespan than previously thought. Ghawar, for example, has 48.2 Bbbl of oil left, which would last another 34 years at the maximum rate of production. Nonetheless, companies are often able to boost the reserves over time by deploying new techniques or technology.
In total, the kingdom enough for another 52 years of production at the maximum capacity of 12 MMbpd.
