In NGI’s Mexico Natural Gas Prices index we provide cheapest-to-deliver comparisons for the following locations in Mexico: Aguascalientes, El Encino, Guadalajara, Monterrey, Tuxpan and Villa de Reyes. These locations in Mexico are served by multiple pipelines, and the cheapest-to-deliver comparisons simply refer to the least expensive option to move gas to a particular delivery location from those various supply routes.

Our Wahalajara Price table shows the costs of shipping gas from the Waha Hub in West Texas to Guadalajara via the Roadrunner (U.S.) and Fermaca (Mexico) pipeline systems. Although these same prices are available in our main Mexico Spot Gas Prices table, this table allows readers to isolate price changes specifically along the Wahalajara system that has been underwritten by CFE.

Each business day, NGI measures the amount of gas that is exported via pipeline from the U.S. to Mexico, and we display these data in two forms. The first is our Mexico NatGas Flow Snapshot, which shows pipeline exports into Mexico via South Texas, West Texas, Arizona and California, as well as the combined total of these four regions. The second is the U.S. NatGas Pipeline Exports to Mexico chart, which displays these data for the previous 10 calendar days.

NGI obtains these data from the electronic bulletin boards (EBBs) of U.S. interstate pipelines, as well as from the emerging EBBs in Mexico. Intrastate pipelines in Texas are the major source of export capacity into Mexico, and unfortunately, they are not required to have standardized EBBs, and therefore typically do not make their daily flow data available to the public. In these cases, we get flow data from the connecting Mexico pipeline, which we are able to do for the majority of the intrastate systems.here.

The NGI & Gadex Weekly Mexico NatGas Flow Tracker is a weekly table and map designed to capture flows along various key pipeline systems within Mexico. Mexico flow data that are delayed by several days are more reliable than same day figures – Some pipelines in Mexico provide data on a lagged basis, some revise posted volumes several times after the fact, and others publish data of lesser quality. Using data that are several days old allows us to not only reconcile and “make sense” of these disparate data sets, but also include flows for more pipelines than we otherwise would have.

Additionally, this table, with data provided by leading energy consultancy Gadex, includes flow volumes expressed in Bcf/d and takes into account localized btu values to simplify comparisons with border flow data, improved capacity utilization data to identify how much interruptible transportation is available, flows from key production areas within Mexico, and arrows to depict the direction of the flow on the pipelines.
