The company head office and its main Processing Center are located in Tallinn (Estonia). Regional offices are located in London (UK), Manama (Bahrain) and Asuncion (Paraguay).

Information about software

The main software tool for marine data processing is the REVEAL package from Shearewater. We also use software products from other developers (Paradigm, Flatirons, RadEx Pro) depending on client requirements and complexity of geological setting.

Software packages:

Shearewater REVEAL (licensed)
Flatirons (licensed)
RadEx Pro (licensed)

Information about hardware

Main Data Center (Tallinn) consists of more 3520 CPU cores (176 nodes by 20 CPU cores each) and more than 1500Tb of useful data storage. Each node carries at least 128Gb of RAM (112 nodes of that kind) or 256Gb of RAM (64 nodes).

In our IT environment, we rely on the following hardware and software technologies:
