Sharp Reflections announce expansion of its 4D capabilities with PreStack Pro 6.2 07 May 2021 The software update is set to dramatically improve interpretation efficiency and increase oil recovery from large fields. By accelerating the identification and mapping of production-induced seismic changes, the new 4D features will enable operators to find oil in bypassed or poorly-drained sections of their reservoirs. Interpreters need no-longer manually compute the differences between vintages on each stack Pre-stack ‘gathers’ can now be used to store collections of stacks from different seismic vintages With everything in a single volume, interpreters can see the differences between stacks without ever having to calculate them, vastly improving efficiency in interpretation activities
