Applications

Geological overview: located in the west side of the West Long Nan nose-shaped structure in the central depression area in the Songliao Basin; sandstone
Wellbore structure: 139.7mm casing
Perforation solution: 4’’ Multi-pulse FracGun and common 4’’ jet perforators are respectively applied in six wells distributed in the adjacent areas in the same zone in the same block
Conveyance: wireline conveyed perforation
Results: The six wells with FracGun witnessed stable production. The total perforation interval depth of the six wells was 28.2m, average 4.7m per well; total daily production fluid was617bbl/d, and total daily oil production was 515bbl/day, with average water content of 21.8%. The average daily production fluid of a single well was 264bbl/d and daily oil production was 34bbl/d. In contrast, for the six wells with conventional jet perforator, the average daily production fluid of a single well was only 5.6bbl/d and daily oil production was only 34bbl/d
