Survey Merge

Merge several input 3D seismic cubes

The user interface allows the user to easily define several input seismic cubes of different sizes, orientation, geometry, amplitude values and sampling rates. It also allows input cube prioritization and definition of a set of polygons to select seismic regions that are more valuable to the user, ignoring dead traces or traces with poor quality.

Plug-in Overview

Merge several 3D cubes of different survey/orientation. Survey Merge plug-in allows the merge of several input seismic cubes into one single output cube defined by the user. It can merge cubes of different sizes, orientation, geometry, amplitude values and sampling rates. It also allows input cube prioritization and definition of a set of polygons to select seismic regions that are more valuable to the user.

Specifications

• Available both as a process and as a work step
• Workflow variables can be used to define output/input cubes and polygons
• It can created a may have distinct Z top values
• The input cubes don’t necessarily have the same Z top value
• Input cubes can be either 8 bits or 32 bits value format
• There is no limit on the number of input cubes and polygons
• When no polygon is defined, the entire input cube is used
• Merge can be used to resample 3D cubes to desired resolution and orientation
• GPU novel approach to increase merging performance
• Traces outside polygons can be initialized with a desired float value
• Different amplitude values range can be normalized to a specified range
• Prioritization of input cubes is supported
• Optimized memory management allows dealing with large output/input cubes

Features

Increase Petrel functionality and performance. It is available both as a process and as a workstep in the Petrel workflow manager. The user can create a new output cube either in the current project folder or in a different folder, if more space is required. Alternatively, the user can overwrite an existing cube with new seismic data. Merge is using a novel GPU approach to increase performance when dealing with complex polygons and millions of traces.
