TYPES OF STORAGE
F | Field storage in depleted oil & gas reservoirs.
A | Aquifers
R | Reef
S | [NAME]
B | Bedded salt
M | Facilities developed in abandoned mines
<> | Storage facilities that are in the conceptual or developmental stage, with in-service dates after the 1997-98 winter heating season.
 | In some cases the chart shows two entries for a single storagae facility.
 | The first entry shows current volumes, while the second shows potential future volumes as a result of planned expansion.
 | <> also designate a few facilities that are current inactive, but are available for future use.
[NAME]
 | Native (or Base) gas
 | Working (Top) gas
 | Third Party Capacity- Available to be leased to third party customers.
 |  | Pipelines have unbundled storage services to allow for third party leasing under Order 636.
 |  | Some distributors have also made storage capacity available.
 |  | Most companies have retained a portion of storage for system supply and balancing.
 | Companies that operate their facilities as a pool:
 |  | ANR Pipline
 |  | CNG Transmission
 |  | Colorado Interstate Gas
 |  | Columbia Gas Transmission
 |  | National Fuel Gas
 |  | Natural Gas Pipeline
 |  | Pacific Gas & Electric
 |  | Southern Natural (Sonat)
 |  | Southern California Gas
 |  | Williams Natural Gas
 |  | Williston Basin
 |  | Transgas (in Canada)
 |  | Third party volumes for individual facilities are prorated based on the facilty's proportionate share of the company's total volumes.
INJECTION/WITHDRAWAL RATES
 |  | With the exception of salt dome formations, injection and withdrawal rates can vary dramatically over the course of the season.
 |  | Highest injection rates posted during times of depletion,
 |  | Highest withdrawals occurring when the field is full and pressure is high.
 |  | Companies have generally provided peak numbers for both injection and withdrawal.
 |  | Because injection figure are not universally available, state and country totals for this column should be viewed as incomplete data.

75 | The interconnect with Amoco is not in use at this time.
76 | All capacity, including expansion volumes, are dedicated to Houston Lighting & Power.
77 | One cavern has been taken out of service, to be releached and expanded.  Injection and deliverability of the releached cavern are estimated and could go higher.  Expected to be on-line October, 1998.
78 | Owned by TriStar Energy but operated by Lone Star.
79 | Lone star allocates a small amount of space for storage customers, which fluctuates from month to month.
80 | MidTex is a partnership of subsidairies of MiCon and NIPSCO.
81 | Subsidairy of Mitchell Energy.
82 | Total and working capacity could be dramatically increased with additional withdrawal/injection.  Tejas Gas Pipline connects to Amoco, HPL, TETCO, MidCon texas, Channel, Valero, Dow and Exxon, with direrct connect ot storge facilities possible.
83 | The first commercial gas well is the State of Virginia was drilled in the Early Grove field in 1930.
84 | Development of future capacity of 3 Bcf from newly created caverns is planned.
85 | Planning an expansion to 18 Bcf working capacity, 850 MMcf/d deliverability by Fall 1999.
86 | A subsidiary of Columbia.  Deliverability for both [NAME] and [NAME] is limited to 48 MMcf/d based on contracted capacity on Columbia's system.
87 | Five potential salt caverns under development, each with 2.5 Bcf working, 1 Bcf cushion, able to recycle 12 times a year.  Numbers on map are for two caverns.
88 | Base gas not published; AEC allocates 64% of its working capacity to storage customers.
89 | About 30% of working gas can be store for others.
