i ~1 <br />4.1.6 Wells Associated With the WRN Project <br />An inlet screen was reinstalled in cavity #3A recovery well 3A-5V when a roof collapse <br />damaged the original screen. This second screen was in operation for a period of <br />approximately two months before it was damaged by another roof fall. Plugging in cavity <br />#4A, recovery well 4A-4V, resulted in it being recompleted as an injection well. A <br />commercial downhole screen and a submersible pump was installed in 4A-tiV and the well <br />placed on recovery. This well had been the injection well for cavity #3A. <br />Shut-in well 26-3C was converted to an injection well. The backside of the well was <br />cemented to surface. The casing was tested to 300 psi to meet UIC requirements <br />following cementing. Short radius technology was used to drill the laterals to connect to <br />the adjacent cavities. Connection was made to cavity #3A but after drilling out 220 feet <br />with the pressure nozzle, no connection was made to cavity #1A. <br />The casing on well 4A-4V was cemented and the well prepared for injection. A plug <br />immediately above the screen was cleared and the well prepared to meet UIC <br />requirements for injection. The well is presently shut-in awaiting future use. <br />Well 1-3A was drilled in late 2001 between cavities #1A and 3A. This well was intended <br />as a recovery well for cavity #1A, and secondly as a recovery well for cavity#3A. Several <br />attempts were made to connect to the adjacent cavities. After repeated failures the <br /> <br />13 <br />
