SPAN Rock

Stressed-rock perforating analysis

Overview

Reliably model perforating performance to optimize well completion efficiency

Get the most out of your oil and gas project with the best perforating gun system and charges recommended by SPAN Rock™ stressed-rock perforating analysis. This easy-to-understand, comprehensive model helps users design perforations and predict how productive a well will be in a wide range of applications.

Input parameters include casing, cement, and rock properties; wellbore geometry (orientation and up to five concentric casing strings); and completion fluid characteristics. SPAN Rock analysis matches these with performance and positioning data for the gun system and charge to predict perforating performance. You can analyze skin as solely perforation skin or as the total skin effect.

Perforating performance testing under real-world downhole conditions

API RP 19B Section 1 data is useful for comparing perforating system performance, but it doesn't accurately represent flow performance through rock formations in downhole environments. That's why we also conduct shaped charge tests on different stressed rocks. This helps predict how well perforators will work underground.

Our PowerJet Nova™ extradeep penetrating shaped charges are the deepest penetrating in the industry, tested for deep penetration in extremely hard rock.
