OpenZGY is an open source library of the ZGY file format for 3D seismic post stack data.
ZGY is a file format used for storing 3D seismic trace data. ZGY is the standard format used for seismic interpretation workflows in Schlumberger’s Petrel E&P software platform. Data is commonly converted to ZGY from SEG-Y format.
ZGY utilizes bricking to store multiple resolutions of a data set based on an octree data structure. A brick typically consists of 64x64x64 samples, though brick sizes can vary. The ZGY format also supports compression of data.
