1. Gas will be directed through flow and pressure instrumentation and will be <br />initiated down either or both the short 4'/2' tubing or the short 7" casing <br />on the well. Concurrent with the gas injection, fluid from the cavity will be <br />directed from the long 4 YZ" tubing of the well through flow and pressure <br />measurement and combined with the wellfield production fluid and <br />transported by pump to the plant stripping facility. <br />2. ASLLP envisions initiating the test at rates between 10 - 20 gallons per <br />minute of displaced fluid from the cavity for the initial startup. This will <br />allow ASLLP to address any equipment or instrumentation issues that <br />may be present. <br />3. During the startup phase, the well will be temperature logged every 24 <br />hours. At present, it is unknown the degree of resolution that the <br />temperature log will provide. It is anticipated that by shutting in the well <br />for a period of 4 - 8 hours, a measurable temperature difference between <br />the fluid and gas can be observed. <br />4. The initial temperature logs will be performed after 0, 2, 4, 6, and 8 hours <br />of shutting in the well. The "wait time" procedure for the temperature log <br />will be adopted to correspond with the highest degree of gas-fluid <br />interface resolution. <br />5. As information and experience is gained on the temperature logging <br />procedure, the time interval between temperature logs may be adjusted. <br />It is possible that the temperature log time interval could be increased up <br />to 48 hours between logs. <br />6. After completion of the startup phase, the injection rate of the gas and the <br />subsequent flow of displaced fluid will be slowly increased. The flow of <br />displaced fluid will be the operational control. It is anticipated that <br />displaced fluid flow rates of 50 gallons per minute can be achieved and <br />maintained. <br />7. The displacement will continue until a minimum of 10 feet of displacement <br />of the fluid is achieved. <br />8. Upon completion of the displacement, the well will be shut in. The gas <br />pressure from the well will be slowly vented. <br />9. ASLLP will submit a written report of the displacement process including <br />all process variables and calculations of the volume versus depth <br />relationship. <br />ASLLP has several wells that can be characterized. The following sections <br />discuss two alternatives: <br />Alternative 7 <br />Well 29-24 (Figure 1) is on a growth trend which indicates it will be the first <br />well to achieve a 200 foot diameter cavity sometime in the early spring of 2004. <br />As Well 29-24 approaches the 200 feet mine plan diameter, 29-24 can be placed <br />on standby and a downhole seismic measurement can be performed.
