Premier Oil shares were up on Thursday after the company updates the market on the successful completion of part of its Zama well appraisal program in the Gulf of Mexico. According to the update, the appraisal revealed 152 metres of net pay encountered above the oil water contact.

The death toll from a fuel pipeline explosion in central Mexico last week rose to 91 as Pemex defended its response to one of the deadliest incidents to hit the state-run oil company in years.

Mexico’s president vowed on Saturday to redouble his fight against an epidemic of fuel theft after thieves punctured a pipeline north of Mexico City, causing an explosion that killed at least 73 people and injured 75 others. The blast underscored the deadly perils of the fuel-theft racket, which has cost the government billions of dollars a year and has been the target of a weeks' long crackdown by the administration of Mexico’s new president, Andrés Manuel López Obrador.

Mexican President Andres Manuel Lopez Obrador said on Tuesday that widespread fuel theft extended to oil drilling platforms and he pledged to take actions to alleviate shortages sparked by his crackdown on gasoline thieves.

Premier Oil has taken advantage of its second consecutive year of record oil production to make larger than expected cuts into its still-significant debts. The London-listed oil and gas developer, with interests in the Falkland Islands, expects its financial results to reveal end-of-year debts of US$2.3 billion, after removing US$390 million from the total following a sharp rise in oil output.

Gasoline shortages in Mexico sparked by a crackdown on fuel theft prompted warnings from business leaders that industries like car making will suffer if the shortfalls persist as lines at gas stations in the capital grew during the week.

President Donald Trump warned of murderers and gangsters spreading across the country during a visit to the US-Mexican border on Thursday to push his demand for a multi-billion dollar wall.

United States president Donald Trump has demanded funding for his long-promised US-Mexico border wall to halt “a growing humanitarian and security crisis”. But in his first TV address to the nation from the Oval Office, Mr Trump did not declare a national emergency to bypass Congress and build the barrier.
