Schlumberger SPAN Rock

836 Schlumberger SPAN Rock v9.1.5 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 solely as 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 downhol
