Pemex is taking matters into its own hands. The recent tender for the construction of the 340 kb/d Dos Bocas refinery was declared void – all participating companies proposed a longer and more expensive project. Unsatisfied, the Mexican government has announced that Pemex will carry out the project with the help of Mexican subcontractors. But many are doubtful of the plan. So far, few project details have been disclosed meaning many questions remain. • Is the Dos Bocas refinery necessary for Mexico to be self-sufficient in gasoline? • Can it be built for US$8 billion and within three years? • Will the refinery add value to Pemex's portfolio?
