Le macro-gisement Cantarell a prodigué d'importants volumes d'hydrocarbures et de grands bénéfices pour le pays, mais depuis 2004 il est entré dans son déclin affectant la plateforme de production de pétrole.

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Major oil fields have played an essential role in the global hydrocarbon supply, but the majority are now in decline. The Cantarell macro-reserve has produced significant volumes of hydrocarbons and brought countless benefits to the country, but starting in 2004, the exhaustion of the Cantarell supply began to affect the oil production platform. This research studies all of the factors that have had an impact on the performance of this macro-reserve, which are fundamental to explain the current state of affairs. The conclusion is that the management of the Cantarell oil field was less than optimal during the three time periods identified in the paper, as decisions were made on a non-technical basis, which contributed to the decline and the series of challenges facing the oil complex today. These difficulties could, in turn, be mitigated through the use of technology.]]></p></abstract>
