Mexico’s Natural Gas Deficit. The Path to Energy Sovereignty

Mexico’s natural gas imbalance has become a structural risk with direct implications for national security. As of April 2026, demand is approaching 9 Bcf/d, yet domestic production meets barely a quarter of that requirement. The shortfall, now exceeding 75%, is largely covered by pipeline imports from Texas and Louisiana.

This level of dependency represents a critical vulnerability to international price volatility and climate-related disruptions, a risk further magnified by the fact that natural gas fuels between 65% and 75% of Mexico’s power generation. At the same time, the country’s ability to respond has been eroded by a sustained decline in upstream activity.

Capacity Erosion, Idle Assets

From a services-sector standpoint, Mexico’s production challenge is not about resource availability, it is about execution capacity. The constraint is physical: fewer rigs, fewer interventions, and a shrinking operational footprint.

The country is currently running just 32 drilling rigs, a fraction of the more than 100 units active a decade ago. Predictably, this has translated into a steady decline in active wells. Between 3Q24 and 3Q25 alone, the producing well stock dropped nearly 9%.

The contraction is visible across both oil and gas. In crude, more than 300 wells were shut in over a 12-month period. In non-associated gas, the active base has fallen below 2,400 wells.

The broader picture is even more telling: Of more than 34,000 wells drilled historically, barely 1 in 5 is producing today. In the Southeast Basins, over a third of onshore wells remain shut, representing stranded production that could be brought back online through workovers, stimulation, and enhanced recovery services, if funding and execution capacity were restored.

Meanwhile, the assets that remain active are being pushed harder, often without the maintenance cycles they require. The result is rising operational risk alongside declining output.

Without a functioning drilling cycle and a financially viable services ecosystem, responsible for the vast majority of specialized field operations, production targets become aspirational. What is not drilled, completed, or intervened simply does not produce.

Shale Resources, Mature Fields

Looking ahead, Mexico’s gas strategy hinges on two fronts: unlocking shale resources and stabilizing mature fields.

The resource base is not in question. More than 60% of the country’s prospective gas resources, estimated at 545 Tcf, are located in shale plays across Burgos, Sabinas and Tampico-Misantla. The challenge is execution at scale.

While the Eagle Ford has seen over 25,000 wells drilled, Mexico has yet to reach even 50. Without repetition and scale, there is no cost curve.

Today, a shale well in Burgos can cost roughly 30% more than in Texas, driven by fragmented midstream infrastructure and limited availability of water and proppant logistics. In the Southeast, the contrast is even sharper: HPHT wells can take up to five months to drill at costs reaching US$90 million.

Under a $5/MMBtu sub-US price environment, these economics are simply not competitive.

What is required is a shift toward a manufacturing model, standardized well designs, continuous drilling programs, and real-time data integration. This is precisely where a capable and well-capitalized services sector becomes indispensable.

At the same time, mature fields offer the fastest route to stabilizing production. Decline rates of 10–15% in assets such as Ku-Maloob-Zaap leave little margin for inaction.

Here again, the opportunity is immediate: thousands of shut-in wells with existing infrastructure could be reactivated through relatively well-understood interventions.

Yet, current investment patterns remain heavily skewed. Around 85% of upstream CAPEX is still directed toward sustaining existing production, with limited allocation toward efficiency gains or technology deployment.

Without rebalancing this approach, both shale potential and mature-field recovery will remain underexploited.

From Ambition to Execution

Mexico possesses the geological endowment required to transform its energy reality, with shale resources estimated at 545 Tcf. However, the country is in a critical race against time: proven reserves (1P) provide only nine years of production at current extraction rates.

In this context, energy sovereignty cannot be treated solely as a policy objective; it must be executed as an industrial strategy grounded in operational continuity and technical efficiency.

Success will depend on meaningful administrative simplification capable of reducing project development cycles from the current 30 months to internationally competitive levels below 11 months.

Only through an ecosystem that ensures technical certainty and operational liquidity will Mexico be able to reactivate the 35.3% of shut-in wells in the Southeast and deploy the “factory drilling” model needed to secure long-term power stability and industrial competitiveness.

Ultimately, the path forward depends on rebuilding a functional partnership between PEMEX and the services sector. This is not a tactical consideration, it is foundational to Mexico’s ability to secure its energy future.
