With a lack of work in the oilfields of Alberta, Canadian companies big and small are increasingly looking to Mexico to get a stake in the billions of dollars being spent in the country's newly opened energy sector.

TransCanada and ATCO already have a presence in Mexico, with other companies like Suncor and SNC-Lavalin showing interest. On Monday, ATCO CEO Nancy Southern described the country as having "vast opportunities available."

Mexico is welcoming private investment after the state-owned company Petroleos Mexicanos (Pemex) has controlled every aspect of the oil and gas business for more than seven decades. Slowly, Mexico has begun inviting private companies to invest in everything from exploration, production, transportation, refining, storage and sales.

The timing is ideal considering the slowdown in Alberta's oilpatch.

"There is definitely a desire. Mexico is shaping up very nice," said Mark Salkeld, with the Petroleum Services Association of Canada. "You get into downturns like this and our member companies start looking international."

Canadian interest

Canadian energy companies have been involved in oil and gas production around the globe for decades. Salkeld himself has worked in Europe, Siberia and Australia during his career.

"You can find a Canadian in just about every oilpatch in the world, either on an individual basis or a company basis," he said.

Since oil prices began tumbling in 2014, tens of thousands of people have lost their jobs in Alberta, Saskatchewan and Newfoundland and Labrador, as corporate revenues nose-dived.

Mexico is much closer than most other foreign locations, as crews can drive down equipment from Canada.

In addition, Salkeld joked, "we have the technology to follow the geology under the Trump wall."

Mexico's Energy Minister Pedro Joaquin Coldwell said Monday in Calgary that the full implementation of the energy sector reform will take seven years, although some parts of the industry have already opened up to private companies.

Mexico's state-owned company has faltered in recent years with declining production and revenue, which led to the reforms. Pemex wasn't able to develop enough technology to unlock the country's reserves.

"We need to develop technologies for the new era of hydrocarbons," said Coldwell.

Creating all the new rules and regulations to unlock the energy sector has not been easy. Both the Alberta Energy Regulator and the University of Calgary are working with Mexican officials to transition to an open market.

"Disassembling that organizational structure as humanely as possible and architecturally designing a marketplace new system is a gargantuan task," said Harrie Vredenburg, with the U of C's Haskayne School of Business.

Billions worth of bids

Suncor is one of the 21 companies signed up to bid for some of Mexico's deepwater properties. Other firms include ExxonMobil, Shell, BP and Murphy Oil. Mexico will accept bids in December and they are expected to generate billions of dollars.

In the last year, Vancouver-based Renaissance Oil won a bid for some small onshore properties from Pemex.

Mexican officials say they are meeting with SNC-Lavalin this week, as the company is said to have an interest in the country's transmission grid expansion.

TransCanada and ATCO are involved in natural gas pipelines in Mexico.

Canadian technology

Mexico's state-run oil company has announced a halt to some of its exploration and production projects, while foreign investors are being welcomed. (Associated Press) Mexico is trying to court international companies because the country lacks the technology desperately needed to boost oil and gas production. In particular, the country lacks expertise in fracking and deepwater drilling.

"[Canadian companies] have a lot of experience in unconventional resources. We have huge potential in that regard that we have not been able to exploit to the fullest," said Fernando Zendejas, head of Mexico's Department of Energy legal unit.

Currently there are no rules in place when it comes to fracking, but they are coming. Zendejas said they will strive to protect the environment but not be as prohibitive as some European countries.

"There are some guidelines already, but it is not formal regulation. That's what we have been working on," he said.

The Canada West Foundation, a Calgary-based think-tank, has cautioned that investing companies will face risks, including violence, crime and uncertainty about the new regulations.
