Oil production from Mexico’s giant Cantarell offshore complex continued its steep decline in 2007, dropping to a combined average 1.458 million barrels per day (mbpd) of production from all the fields, down 18% from an average 1,776.2 mbpd in 2006, according to statistics from the Energy Ministry available on the Sistema de Información Energética (SIE).
Cantarell accounted for 47.3% of all of PEMEX’s crude oil output in 2007, down from 54.6% in 2006. Mexico’s total crude output dropped 5.3% in 2007 compared to the year before, down to 3.082 million barrels per day from 3.256 mpbd in 2006 according to the SIE statistics.
Production from the Akal-Nohoch field in Cantarell, which accounted for 98% of the output from Cantarell in 2007 and for 46% of Mexico’s total crude oil output in the year, dropped to an average 1.261 mbpd in December 2007, down 16% from December 2006.
The rate of decline remans more rapid than PEMEX had anticipated. In testimony before the Energy Committee of the Mexican Senate in November 2006, PEMEX CEO Luis Ramirez Corzo said that production at Cantarell would decline by an average of 14% per year between 2007 and 2015. (Earlier post.) Cantarell’s production peaked in 2004 at 2.113 million barrels per day, according to SEI data. In 1997, PEMEX began nitrogen injection to maintain reservoir pressure. The injection regimen supported increasing crude oil production from 1.083 million barrels per day in 1996 to the peak in 2004.
