L & TD has used this equipment since 1988 in hundreds wells. These wells were located at Bach Ho, Dai Hung and Rong oil fields. The angle of wells may have been to 70 degrees and the depth up to 5000 m.
This equipment can be uesd without cutting off electric supply.
Wireline perforation has been used very safely in our oil field’s. Advantages of wireline perforation is the gun can not fire if hydrostatic pressure less 10 atm and the length of the gun may be from 3 to 8 meters. |
