On 28 April Pemex released a report on Q1 2015 security developments that revealed alarming data on hydrocarbons theft in Mexico. Compared to the same period last year, the number of new illegal siphons discovered nationwide rose from 767 to 1,211 – an increase of nearly 58%. The states with the highest incidence of illegal siphons included Tamaulipas (207 siphons), Guanajuato (151), Puebla (144), Tabasco (140) and Jalisco (115). Tabasco’s inclusion in this list is striking: during the same period in 2014, the state only reported 33 illegal siphons, and was considered relatively safe for oil products transport. The Pemex report signals that the negative security trend in the Mexican oil and gas sector has not been reversed.
