h'cll SO'd 3S li-2 <br />• Procedure: <br />A falling head slug test was performed on SOM 38 H-2 on September 7, 1982. <br />The slug used measured 14.5 feet by 1.32 inches diameter. After inserting the <br />slug into the well, water level measurements were recorded for 320 minutes. <br />After 151 minutes the water level measuring probe was removed from the well to <br />measure static water level in another well nearby. When the probe was replaced <br />in SOD1 38 H-2 the water level appeared to have risen. As subsequent data points <br />were plotted, the data fell above, but on the same shapped curve as previous <br />points. A correction was made (minus 1.171 feet from measured water levels <br />after 261 minutes) adjusting the late test data to be graphically consistent <br />with early test data. <br />Interpretation: <br />. A relatively good match with the Cooper et. al. type curve indicates a <br />transmissivity of T=0.4 gpd/ft. Late test data was used with the line source <br />• method to calculate T=0.38 gpd/ft., which agrees very closely with that obtained <br />by the type curve method. <br />The well completion report indicates that the well is gravel packed through <br />shale and sandstone of the Barren A1ember. The gravel pack length is approximately <br />185 feet, which is used with T=0.4 gpd/ft. to calculate formation permeability, <br />K=0.002 gpd/ft 2. <br />• <br />s6 ESA Geotechnical Consultants <br />
