Colorado Interstate Gas Company, L.L.C.
Spring Bottom Hole Schedule 2024 Update #1
Revision:
Colorado Interstate Gas Company, L.L.C is extending the Latigo Storage BHP Survey end date from April 24, 2024 to April 28, 2024.
Withdrawal estimate provided.
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 March 19 through May 10, 2024. 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 April.

Note: Flank has two reservoirs which will be tested separately. Flank Morrow reservoir will be tested beginning March 19 through March 26 and Flank Cherokee reservoir will be tested beginning March 27 through April 3. The impact to injection capability will be minimal, and no reductions to customer's firm injection rights will be made during the Flank Bottom Hole Pressure Survey.
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.
