In many older oil fields, companies inject gas to keep the pressure in the wells high and the oil flowing. In the case of Cantarell, Mexico injected vast quantities of nitrogen in the past few years. But the gas can only do so much, and using it means the decline in production can be sudden and sharp. In the case of Cantarell, which lies in the shallow waters of the Gulf, experts say that seawater is fast invading the wells.
linkThe days when you could find a supergiant oil field while fishing are over. Cantarell came late, in the oil age. That meant this global giant would receive all the best doctoring modern technology could provide. The result is that Cantarell was pumped out effectively and hard, especially after the technique to re-pressurize the field was adopted. This allowed for a spike high of daily production to be captured for several years, late in its life when a field would otherwise go into gentle decline. The result? Quicker monetization of the oil for the benefit of the Mexican state. But then the price: a catastrophic, fast crash.
linkCantarell was second largest field in the world behind Ghawar. 2 yrs ago it was producing over a million barrels a day. It has now fast crashed, as had been predicted for wells in which enhanced recovery was used.
Yes the decline has flattened somewhat over the last year, but at 400,000 barrels a day, and with seawater invading the well, within months it will no longer be cost effective and will be, for all practical purposes, dead.
Mexico is NOW a net importer. Yes, they claimed it is to increase refinery efficiency, but we see the numbers. We know the real reason.
The death of the supergiants is at hand, and there is nothing to replace them.
