A feature about the situation in the state of Tamaulipas in the north-east of Mexico by Argus:
"Over the past seven months, security experts working with oil, gas and renewable energy companies in the region have documented 15 deaths from cross-fire, seven assaults by cartel members fleeing confrontation with a rival gang, 25 kidnappings to extract money or extort information about rival gangs or for fuel theft, as well as numerous cases of vehicle theft and telephone extortion. Despite the high level of criminal activity, charging companies a fee to operate in the state, known as derecho de piso, is not common practice in Tamaulipas as it is in other part of the country.
A handful of illegitimate oil services companies, suspected of being fronts for laundering the profits of fuel theft, are also thought to be responsible for widely documented theft of heavy machinery, valves and pipes from oil field sites.
"Tamaulipas has a very specific security dynamic circled around criminal lookouts," Garcia said. "The groups are not necessarily tracking the companies themselves but are trying to keep track of rival organizations."
Companies operating in the state employ a range of protocols to protect their staff and operations, including daylight-only working hours, maintaining a high industrial profile through the use of vehicles and uniforms clearly marked with company logos, kidnap training for personnel, the use of hotels and apartment complexes that commit to anti-kidnap protocols, and the sharing of real-time data on criminal incidents in order to plan daily personnel movements."
