    Reminder - Storage Bottom Hole Pressure Surveys

     

     

    The four Storage Fields utilized by Colorado Interstate Gas Company, L.L.C. (CIG) to provide No Notice Transportation (NNT) and Storage Services will undergo scheduled Bottom Hole Pressure Surveys from September 15, 2026 through October 19, 2026. As explained below, this work will impact firm customers' ability to inject during this period by reducing the regular Available Daily Injection Quantity (ADIQ). For informational purposes, CIG has also included an estimate of withdrawal impacts so customers may plan their business accordingly.

     

    The week that maintenance is scheduled for each field is listed below. Each field's maximum injection and withdrawal capability is shown as well as the field's related percentage of total injections/withdrawals and the net injection/withdrawal available for that week. These numbers are based on the projection that storage inventory will be within normal guidelines at the end of September.

    *Note: Flank has two reservoirs which will be tested separately. Flank Morrow reservoir will be tested beginning September 23 through September 30, and Flank Cherokee reservoir will be tested beginning September 15 through September 22. The impact to injection capability will be minimal, and no reductions to customer's firm injection rights will be made during these separate Flank Bottom Hole Pressure Surveys.

     

    During the Bottom Hole Pressure Surveys for FT. Morgan, Latigo and Boehm firm shippers' ADIQ will be reduced by the percentage indicted above consistent with Part IV: General Terms and Conditions (GT&C) Sections 1.2(c) and 11.6 of CIG's FERC Gas Tariff Second Revised Volume No.1. For example, during Ft. Morgan maintenance, shippers will be limited to 61.5% (100-38.5) of the Standard ADIQ

     

    Other Impacts to Shippers:

     

    1. Shippers are asked to manage flowing supplies to keep injections and withdrawals within the adjusted limits. If small injection overruns occur, they will be based on the adjusted limits and will be authorized for NNT customers. However, if operational concerns arise because of higher levels of overrun injections, a Strained Operating Condition (SOC) may need to be implemented, and overruns will not be authorized.

     

    2. During the week of the Ft. Morgan outage, injections under the High Available Daily Injection Quantity (High ADIQ) option described in GT&C Section 1.2 will not be supported.

     

    3. Injections to and withdrawals from interruptible storage accounts will not be scheduled during the period of Bottom Hole Pressure Surveys.
