GEOGALS is a seismic data processing company, incorporated in 2011 in Tallinn, Estonia. As an independent service provider, GEOGALS uses modern processing software and powerful hardware to process large volumes of 2D and 3D seismic data acquired in various geographic and geologic settings — land, transitional and marine environments.
01People
GEOGALS employs 15–20 specialists — geophysicists, geologists and IT staff with a strong professional record. The combined expertise of our people and decades of experience across a wide range of petroleum provinces allow us to carry out projects of any complexity and size. We are experts in cutting-edge procedures such as 3D SRME, WEMA, 5D regularisation, RTM, FWI, Q-PSDM and ES360.
The company head office and its main Processing Centre are located in Tallinn, Estonia. Regional offices are located in the United Kingdom, Dubai (UAE), Manama (Bahrain), Tbilisi (Georgia) and Asuncion (Paraguay).
REAL PHOTO02Software
The main software tool for marine data processing is the REVEAL package from Shearwater. We also use software products from other developers — Paradigm, Flatirons, RadExPro — depending on client requirements and the complexity of the geological setting.

04Availability & reliability
The infrastructure is designed to ensure a high level of availability, fault tolerance and service continuity.
Critical components — compute nodes, storage systems and network infrastructure — are deployed with redundancy to eliminate single points of failure.
The Proxmox VE cluster supports live migration and automatic restart of virtual machines in case of hardware failure.
The BeeGFS distributed filesystem ensures data replication and fault tolerance across multiple storage nodes.
Redundant Arista switching and InfiniBand fabric minimise bottlenecks and ensure low-latency communication.
Continuous infrastructure monitoring enables proactive detection and resolution of potential issues.
Maintenance activities are scheduled to minimise service disruption and are communicated in advance.
05Security
The infrastructure is designed in accordance with industry best practices to ensure the confidentiality, integrity and availability of data and services.
Segmentation of management, storage and compute networks; controlled access via firewalls and ACLs.
Role-based access control across all systems. Administrative access is restricted on the principle of least privilege.
Centralised authentication mechanisms — FreeIPA integration — are used where applicable.
Data is protected through access policies, filesystem-level controls and secure storage configurations.
All administrative access is performed over secure protocols such as SSH and HTTPS.
Regular updates and security patching are applied to operating systems and software components.
System activity and access logs are collected and retained for auditing and incident investigation.
Regular backups and archival procedures ensure data recoverability in case of failure or data loss.
06Facility
The data centre of Levira in Tallinn is a highly reliable and secure infrastructure facility, compliant with international standards for quality and information security — ISO 27001, ISO 9001 and ISO 14001 — as well as national ISKE requirements.
The physical and engineering infrastructure is designed in accordance with high availability and business continuity principles. Full redundancy is implemented across all critical systems, including power supply (multiple independent feeds, UPS and diesel generators), cooling systems and network infrastructure. The facility architecture ensures fault isolation and resilience against external disruptions.
The data centre demonstrates a high level of operational reliability and is designed to support strict SLA commitments, backed by extensive experience in delivering mission-critical services for the telecommunications and media industries.
The network infrastructure follows a carrier-neutral model, with connectivity to multiple independent providers and diverse fibre routes.
