Upstream

Upstream is GT’s core business. The company supports the exploration, appraisal and production of oil and natural gas fields through integrated seismic services— from design and data acquisition, through processing and imaging, to interpretation — as well as comprehensive well logging services.

During the seismic data acquisition phase, the company utilises next-generation solutions, including nodal systems supported by its own technological and operational solutions. These enable the acquisition of high-quality data with minimal impact on the environment and allow fieldwork to be carried out safely, efficiently and with respect for the environment and local communities.

In the data processing and interpretation process, GT utilises advanced methods, including velocity modelling, depth migration, full-waveform inversion (FWI), diffraction and seismic attribute analysis, AVO/AVA, seismic inversion, quantitative interpretation (QI), integration of geological and well data, and solutions supported by automation and machine learning.

The integration of seismic, geological and well data with expert interpretation enables the identification of geological formations, the selection of exploration targets, the assessment of reservoir conditions, the documentation of reserves, the planning of production operations, and the mitigation of risks at subsequent stages of the project.

The client is provided with a reliable basis for identifying structures, assessing reservoir potential, planning wells, documenting reserves and making technical and investment decisions.
