Introduction

Greeting you! We are happy that you chose g-Platform software for seismic processing. This tutorial will provide you with the detailed guiding of all the steps of production 2D land seismic processing sequence.

In each chapter you can find answers how to use g-Platform functionality, explore many different features and interactive tools. You will discover friendly and flexible interface, as well as vast number of conventional and advanced processing modules. Geophysicists are able to resolve any problem, have opportunity to build sophisticated workflows and process many types of seismic processing projects such as 2D/3D land and marine, VSP, Depth Imaging, MutiFocusng and Diffraction Imaging and Ultra high frequency data sets.

In this current tutorial, we are going to use a 3D land seismic data set. It is open data, you can download an input set from the following link: https://wiki.seg.org/wiki/Teapot_dome_3D_survey.

Please, pay attention that the main goal of current processing sequence is to show how to use software for new users. Experienced geophysicist is able to create complex workflows: find the best denoise modules and workflows, regularization and migration parameters, post migration and post stack processing and so on. Therefore, you can download the final cube of some of production processing that is free and try to make better result (http://s3.amazonaws.com/open.source.geoscience/open_data/teapot/rmotc.tar).

Teapot dome 3D data set comes with assigned geometry (npr3_gathers.sgy). Usually, the user should provide the navigation information (for land data, traditionally it's SPS) however in this particular data set, we have the geometry information already there in the trace headers. Therefore, we need to read already existing trace headers information from the input data and do the Binning 3D.

Geomage g-Platform is a unique imaging software for processing your seismic data. Our solutions are based on the latest developments in software and hardware technologies. An approach that allow you to concentrate on the processing and getting superb imaging results.

Geomage solutions support a complete utilization of parallel processing capabilities of GPU and multi-core CPU clusters. This allows a reduction in lengthy processing times and gives a competitive advantage to our clients by delivering faster turnaround for their business decisions.

g-Platform is a sleek modern software which makes the life of geophysicists (both on field QC & production) easier with it's user friendly design, simple yet excellent GUI, faster turn around time, less burden on budget and robust algorithms sums up an excellent processing software suite. Geomage's g-Platform software suite is a complete package for both time and depth imaging. g-Platform software is in line with the modern industry technologies and continuously updates/adds the latest advanced technologies into it's portfolio.

g-Platform was launched in the year 2003 with a small team. Geomage's proprietary technology MultiFocusing (MF) Imaging and Diffraction Imaging (DI) are separate plug-ins which are well integrated into g-Platform software suite. These two are not part of the standard software package. g-Platform can run on both Windows 7/8/10 & above, Linux (RHEL/CentOS) 6.x/7.x and above. The minimum hardware requirements for smooth running of g-Platform are as follows.

3. Minimum ~ 1.5 GB disk space is required for g-Platform installation however 500 GB or more (As per the user project requirement) shall be suggested.

4. Good graphic card (Please check with our support team prior to purchase of the graphic card for compatibility).

Geomage's g-Platform software is still very young when compared with industry stalwarts with respect to it's presence however we are proud to say that the capabilities of g-Platform software is not lesser to any one, if not exceeds the expectations of our clientele across the globe.
