After the 1 -hour period had elapsed, the <br />pressure was checked and found to still be 75 psi. This was an acceptable test result and the <br />line was determined to be leak -free and ready for use. <br />For well MLEX-4, the procedure was similar, but the details were somewhat different because the <br />line was connected to the existing discharge line for wells MLEX-1 through -3. When MLEX-3 <br />was constructed a tee with a 4 -inch butterfly valve was installed in the vault for future connection <br />to other wells (MLEX-4 in particular). The valve held pressure well, so it was possible to test only <br />the pipeline section from well MLEX-4 to MLEX-3. A similar procedure to what is described above <br />was performed- the 4 -inch line was filled with water and pressurized to between 85 and 90 psi for <br />a 4 hour period. Wheeler personnel then went to the site to witness the 1 -hour hold period. The <br />line pressure was reduced from 85 psi to 75 psi and held for 1 hour without adding any water. At <br />the end of the 1 -hour hold period, the line pressure was measured at 75 psi, Again, this was an <br />acceptable test result and the line was determined to be leak -free and ready for use - <br />Both of the new well (MLEX-4 and -5) pipelines were therefore determined to be well constructed, <br />leak free, and ready for operation. <br />RA13001133311333 0111333.01 07 (Extraction Weils)1DOCUMENTS12017 Seepage Wells - EPF Certification docx
