If, requires a 20 percent reduction in pressure then capacity could be reduced by up to 20 percent and capacity through. The company is planning to build two pipelines of the same size in West Texas – the Trans-Pecos Pipeline and the Comanche Trail Pipeline. Genscape’s Natural Gas Notices & Maintenance portal consolidates hundreds of maintenance and notice events from electronic bulletin boards (EBBs) to help natural gas traders streamline their daily processes and stay informed of unavoidable events impacting the market. Texas Eastern can transport 13.06 Bcf/d and offers approximately 74 Bcf of gas storage. Eric Fell TETCO increased volumes flowing southward on Leidy by increasing its storage withdraws from about 100 MMcf/d up to about 650 MMcf/d. Senior Natural Gas Analyst, Erik Fabry The Texas Railroad Commission (RRC) says the explosion of a 42″ natural gas pipeline near the town of Cuero, Texas in June 2015 was caused by a “material failure” on part of the pipeline.

This information should not be relied on by shippers in making or confirming commercial transactions. Flows beginning at the Delmont compressor (the western boundary of the M3 zone) have been cut to zero, and the flow impacts radiate eastward from Delmont. Along with Genscape's unparalleled analyst support and insight, Genscape's Natural Gas Real-Time (RT) service provides the most comprehensive view of public data.

With 8,835 miles of pipeline, Texas Eastern Transmission connects Texas and the Gulf Coast with high demand markets in the northeastern United States, supplying fuel for electric generation facilities and helping to meet peak-day demands. That is being used to increase flows through the Bedford compressor, where flows are up into the 200 MMcf/d range after running around 155 MMcf/d last week.

The amount of time it takes to repair a large diameter pipeline ruptures are usually a matter of days (not weeks). On February 10 and 11, the segment returned to normal rates of approximately 1.3 Bcf/d. TETCO must repair or replace pipe or coating where necessary. Sign up for industry expertise and market news, Copyright © Genscape, Inc. & Genscape International, Inc. 2002-2020, Impacts of TETCO's Natural Gas Pipeline Explosion. Columbia Gas Transmission (TCO) Columbia Gulf Transmission (CGT) Crossroads Pipeline (XRD) Central Kentucky Transmission (CKT) Hardy Storage Company (HRD) Farther east flows are less affected. Last June, a 42” Energy Transfer line near Cuero, TX exploded was returned to operation in three days. The RRC regulates the oil and gas industry and investigated the Cuero explosion shortly after it happened.

The pattern of corrosion suggests a possible flaw in the coating material applied to the girth weld joints following construction welding procedures at the time. If PHSMA requires a 20 percent reduction in pressure then capacity could be reduced by up to 20 percent and capacity through Delmont would be permanently reduced from 2.6 BCF/D to around ~2.1 BCF/D.


The part of the line that exploded was shut off and isolated, but according to the RRC’s report, it was repaired and back in operation about three days after the explosion. The initial impact on flows is significant (see Genscape's Natural Gas Real-Time (RT) TETCO flow map below). TC Energy Office. Informational Postings; Customer Support. There is a chance that TETCO is required to operate at reduced pressure after the repairs are completed. On April 28, just prior to the explosion, flows through Delmont were around 1.3 BCF/D relative to 2.6 BCF of capacity (~50 percent utilization). For after hours business support, please contact Volume Management at 713-627-5059. The rupture occurred in a vacant field a few yards east of Pike County Road 43. Cheyenne Plains; Colorado Interstate Gas; Elba Express; El Paso Natural Gas; Horizon Pipeline; KM Illinois Pipeline; KM Louisiana Pipeline; Midcontinent Express; Mojav While the return of all four lines may take longer than the 1-2 weeks Genscape initially estimated, it appears that at least partial capacity through Delmont is likely to be restored next week (per TETCO’s latest notice). Phone: 1.403.920.2000 Toll-free: 1.800.661.3805 Emergency Numbers. Second: similar events on other pipelines in the US and Canada have taken just a few days to repair. First of all, there are parallel lines adjacent to the ruptured one that may be able to come back into service soon. The southern line has more production tied into it. Based on the timeline of similar large diameter pipeline explosions in the past, Genscape believes repairs are likely to take between 5-15 days, but clearly it could take longer. There have been a number of large diameter pipeline explosions over the years. Liquids Pipelines and Storage TETCO has also been compensating by reducing its deliveries to interstate interconnects. The other lines must also be exposed at least to girth welds in both directions from the point of failure and undergo the same process as the ruptured line.

Genscape collects notices from over 200 pipelines that are fed into the platform within minutes of their availability on the pipeline websites. 22-Oct 15:51 Station 4B South Capacity for October 24 - 26, 2020 Revised (#53866) 21-Oct 17:39 November 1, 2020 Entitlements Available on CI (#53865) Genscape does not know if a pressure reduction will be required. On Saturday, April 30 and Sunday, May 1, TETCO did report backward flows through Delmont of about 180 MMcf/d, though none for today. , PSHMA issued a corrective action order yesterday (summary below). Those two points had been producing about 250 MMcf/d prior to the event. link® system terms of use. Interstate. Informational Postings Customer Support For LINK® application support, please call 1-800-827-LINK (5465), 713-989-LINK, or email the LINK® Help Desk . However, according a critical notice posted to the website, the Force Majeure on Segment 300 remains in place. There are six major power consumers captive to the system that collectively had been consuming roughly 550 MMcf/d.

Please refer to the Operationally Available Capacity under Informational Postings. Corrosion at a weld is the likely culprit, although a final determination has not been made. 1-2 weeks to repair the line(s) from the initial event is our best guess. Alliance Pipeline Limited Partnership (Canada) 25-384-6620: Alliance Pipeline L.P. (USA) 80-978-7513

Deliveries to power plants so far appear relatively unaffected. While there has not been confirmation the other lines have been damaged, TETCO has shut them down as a precautionary measure.
