• At this point, several possibilities were discussed including pump <br />down a thicker plug and/or using a permanent packer. Because of <br />expense and estimated pressures, it was decided to try with a thicker <br />cement plug. National Cementers injected 28 sacks of cement slurry <br />containing 2 percent CaCI to theoretically yield a 144-foot thick <br />plug. However, this plug was also completely washed out, again <br />suggesting much higher pressures and flow rates than estimated. <br />Consequently, a permanent packer was installed by Lynes, Inc. Ten <br />sacks of cement slurry were then pumped down to form a permanent plug <br />above the packer. The next day, neither the cement nor the packer <br />were in place. It was concluded that the packer had failed, since it <br />appeared to have been seated properly prior to cementing. <br />Because of schedule and money considerations, it was decided to plug <br />the entire hole with a fast-setting cement. This was successfully <br />accomplished on May 5 using 100 sacks (100 percent overrun) of speci- <br />• fically formulated cement. An additional 24 sacks of regular cement <br />was pumped in to fill the upper 60 feet of hole after the lower por- <br />tion had set. <br />Testing and Sampling <br />Testing and sampling of the upper two producing zones will be <br />discussed in sections concerning Holes No. 3 and 4. <br />Water from the deepest producing zone was sampled and yielded the <br />following field parameters: <br />Temperature = 18° C <br />p H = 7.5 - 8 <br />Conductivity = 1,550 @ 12° C <br /> <br />
