Remove debris from existing perforations in permeable rocks and increase productivity or injectivity.
Deliver the best productivity from your completion with the optimal gun system and charges specified by SPAN Rock stressed-rock perforating analysis. This simple yet comprehensive modeling guides the user down a logical path for perforation design and the prediction of well productivity. Input parameters include casing, cement, and rock properties; wellbore geometry (orientation and accommodating up to five concentric casing strings); and completion fluid characteristics. These are matched with performance and positioning data for the gun system and charge to predict perforating performance. Skin can be analyzed as solely perforation skin or as the total skin effect.
Although API RP 19B Section 1 data is useful for determining perforating system performance as a comparative tool, it does not accurately represent the flow performance of rock under downhole conditions. SPAN Rock stressed-rock perforating analysis incorporates hundreds of shaped charge test shots made into a broad range of stressed rocks to accurately predict perforator performance downhole. Our most recent research acquired test data at extreme values of rock strength in developing PowerJet Nova extradeep penetrating shaped charges, the deepest penetrating charge in the industry.
Most technologically advanced perforating system laboratory in the industry.
PowerJet Nova extradeep penetrating charges with the PURE system penetrate 9 5/8-in casing, delivering clean, productive perforations.
PetroChina uses through-tubing perforating technique verified with laboratory testing to effectively stimulate an onshore gas well in China.
Running PowerJet Nova charges and the PURE clean perforations system enhances operations in deepwater reservoir, Southeast Asia.
