A segment on the Discovery Channel’s show “How Stuff Works” caught my eye this week and prompted that question. The segment points out that Xanthan gum, fermented from corn syrup, is used in oil drilling. Xanthan is combined with the drilling mud used to cool drilling equipment, and it helps to clear dirt and rock from the mud as well as maintain a pressure cap on the bore hole.
The primary markets for Xanthan gum are of course food and cosmetic ingredients — check your supermarket shelves for the number of products containing it. But enough is used in oil production that a 2006 Saudi Aramco white paper explored establishment of a Xanthan gum production plant in Saudi Arabia to meet oil drilling needs. The white paper projects the market for Xanthan gum for 2007 and 2008 among the Gulf Cooperation Council countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates), using Saudi Aramco’s exploration and production models. For 2007, the projected need was nearly 15 million pounds, and for 2008, nearly 12.5 million pounds.
Arguments about the diversion of food and land for biofuel fail to consider exactly how many non-food products contain corn.
