Norte de Santander is a crude producing department but it has no refineries. It is closer to Venezuelan refineries than Colombian ones and there is a large problem with contraband because Venezuelan gasoline is subsidized and Colombian is not.

Because of the turmoil in its neighbor, the Colombian government has stepped in to assure supply. From a MinMinas press release, translated and with commentary by Hydrocarbons Colombia.
