With the experience of the field work on well AS 28-21, these issues can be <br />easily resolved. <br />Well AS 28-21 performed very well during the displacement test. At <br />the time the test was ended, there were no issues with the displacement <br />procedure. With the experience gained from this test, full displacement of <br />the fluid from an ASLLP solution mined cavity is very achievable. <br />7. Application of Characterization Results <br />The right cylinder cavity diameter calculation based upon <br />production tonnage for well 28-21 is 164.8 feet. The seismic model volume <br />from the cavity characterization is 6% greater than the right cylinder <br />volume, The seismic model has a maximum diameter of 302 feet located <br />within the Greeno bed of the lower ore zone. The ratio of the maximum <br />cavity diameter to the calculated right cylinder diameter is 1.83. <br />In the absence of additional data, an unsupported estimate of <br />maximum cavity diameter can be extrapolated by multiplying the right <br />cylinder diameter by a factor of 1.83. <br />By assuming the maximum diameter will occur within the zone that <br />sustained the longest time period of injection, a further extrapolation can <br />be made as to the position within the cavity of the maximum diameter. It <br />is assumed that a well operated by injecting into the top of the cavity <br />(Tops Mode) would result in a maximum cavity diameter located at the <br />Love bed within the upper ore zone, It is assumed that a well operated by <br />injecting into the bottom of the cavity (Bottoms Mode) would result in a <br />maximum cavity diameter located at the Greeno bed within the lower <br />ore zone. It is assumed that wells operated by injecting into both the top <br />and bottom of the cavity would result in higher than average diameters in <br />both the Greeno bed located in the lower ore zone and the Love bed <br />located in the upper ore zone. <br />To estimate the maximum cavity diameter for each well, ASLLP <br />developed the following selection criteria: <br />Wells operating in Tops Mode greater than 60% of operating time results in <br />the maximum diameter in the upper ore zone. <br />Right Cylinder Diameter * 1.83 =Maximum Diameter <br />Wells operating in Bottoms Mode greater than 60% of operating time <br />results in the maximum diameter in the lower ore zone. <br />
