Build pipelines, not walls - American energy firms are enjoying a bonanza south

rlp

But a ham-fisted assault on NAFTA could jeopardise it

A CHEMICAL engineer at Pemex, Mexico s state-owned oil company, opens a tap

atop a maritime platform in this offshore oilfield in the southern part of the

Gulf of Mexico. She decants a jar of heavy Mexican crude that comes, hot to the

touch, from 3,500 metres below the seabed. It looks like a succulent chocolate

sauce, but smells like the back end of a cow. Taste it, she laughs.

The crude that she is testing is pumped a short distance across the sea to a

vast floating storage tank, known as an FPSO, where it is blended with lighter

crude for export. The FPSO stores about 2m barrels roughly the equivalent of a

day s worth of Mexican oil production. A quarter of that is fed into a

supertanker tied alongside, contracted by Chevron, America s second-largest oil

firm. It then sails north across the maritime border to Texas or Louisiana

where the crude runs through refineries. The refined petrol or diesel often

then returns to Mexico.

These transactions are part of a historic transformation of North American

energy that President Donald Trump appears to have overlooked as he fumes over

his country s trade deficit with Mexico and pours scorn on the North American

Free Trade Agreement (NAFTA). In 2015 the energy trade balance flipped (see

chart). Between 2011 and 2016, it swung from an American deficit of $20bn to an

American surplus of $11.5bn. America earned almost as much from exporting

hydrocarbons to Mexico as from cars and trucks.

This about-turn has been caused by several factors, namely America s shale

boom, Mexico s slumping oil output (down by more than 1m barrels a day in a

decade) and energy liberalisation in 2014 that ended Pemex s 75-year-old

hegemony over the domestic oil industry. This shifting landscape has already

had an effect on Pemex: a recent bump in oil prices, combined with

cost-cutting, has led to its first consecutive quarterly profit in six years.

The ripple effect through North America s energy business has also been quick,

and should expand provided it is not derailed by a hamfisted effort to

renegotiate NAFTA.

The cross-border flow of hydrocarbons is the most tangible change. Petrol from

American refineries amounts to about half of Mexico s domestic consumption.

Last month Tesoro, a Texan refiner, became the first private firm to win an

auction to move imported petroleum products through Pemex s own tanks and

pipelines.

Mexico has also become the destination of choice for surplus American natural

gas, produced in the shale revolution. Sales south of the border have almost

doubled since 2014, as Mexico switches its power generation from coal and oil

to cheaper, cleaner fuels. The capacity of natural-gas pipelines crossing the

border is expected almost to double over the next three years. Since Cheniere

Energy became the first firm to export American liquefied natural gas last

year, much has flowed to Mexico.

Investment is also flowing. American oil companies won five out of the eight

blocks auctioned in Mexico s first sale of deepwater oil licences last year.

That forms part of what Pedro Joaqu n Coldwell, Mexico s energy secretary, says

are $49bn-worth of international investment commitments in exploration and

drilling since 2015. Jos Antonio Gonz lez Anaya, Pemex s boss, says he hopes

to encourage American refiners such as Tesoro and Valero to co-invest in some

of Mexico s six refineries. But all were built before 1980, are decrepit, and

lose about $9bn a year.

The changes are becoming visible at the petrol pump. ExxonMobil, America s

largest oil company, announced in May that it would open its first petrol

station in Mexico this year and invest $300m in fuel distribution over the next

decade. Currently, only one petrol station in Mexico is owned by a supermajor,

BP (its enthusiastic pump attendants work for salaries, not tips, unlike those

at Pemex-branded ones).

At a congressional hearing in Washington this month, experts noted that the

United States, Mexico and Canada are on track to achieve North American energy

independence by 2020 meaning the region will produce more liquid fuels than it

consumes. Cheap, abundant energy will boost the region s industrial

competitiveness; it will also reduce its dependence on less stable producers

such as Venezuela and Persian Gulf States.

But in both America and Mexico, uncertainties loom. The process under way to

renegotiate NAFTA could jeopardise energy co-operation if Mr Trump pulls

America out of the treaty, as he has threatened to do. Since Mexico s energy

liberalisation, NAFTA s provisions have helped provide certainty to foreign

investors. Those safeguards could be valuable if Andr s Manuel L pez Obrador, a

staunch opponent of energy reform, wins Mexico s presidential election next

year. He could take issue with the growing dependence on American fuel. A

vibrant network of North American energy markets is taking shape, but it

remains fragile especially with populists blundering about in positions of

power.
