High-quality seismic data is the backbone of successful hydrocarbon exploration and development. Structural mapping, stratigraphic interpretation, reservoir prediction, and drilling decisions all depend on reliable seismic imaging. Poor processing, inaccurate velocity models, or inadequate quality control can lead to misinterpretation, increased drilling risk, and significant financial loss. At GTN, we provide independent, geology-driven seismic consulting services designed to enhance data fidelity, improve imaging accuracy, and ensure that seismic volumes are technically robust and exploration-ready.
We provide full-cycle consulting support for 2D and 3D seismic processing, including Pre-Stack Time Migration (PSTM) and Pre-Stack Depth Migration (PSDM). Our services cover data conditioning, multiple attenuation, velocity model building, anisotropy handling, and depth imaging in complex geological settings. The objective is to produce amplitude-preserved, structurally accurate seismic volumes aligned with exploration targets and geological models.
Post-stack enhancement services are focused on maximizing interpretability of existing seismic datasets. Through advanced spectral balancing, noise attenuation, structural smoothing, and frequency optimization, we improve reflector continuity and subtle feature detection. This service is particularly valuable for mature fields and legacy datasets where improved imaging can unlock new opportunities without additional acquisition.
In areas lacking full 3D coverage, we implement Pseudo 3D workflows by integrating intersecting 2D lines into a coherent structural framework. This approach improves fault mapping, horizon consistency, and stratigraphic understanding, offering cost-effective structural risk reduction in frontier or budget-constrained exploration areas.
Our passive seismic services include natural seismicity analysis and microseismic monitoring to evaluate fracture systems, stress regimes, and subsurface dynamics. These studies are particularly relevant for fractured reservoirs, unconventional plays, and CCS/CCUS monitoring, providing insight into reservoir behavior without active seismic acquisition.
We deliver Amplitude Versus Offset (AVO) analysis and both post-stack and pre-stack inversion workflows to predict lithology, fluid distribution, and reservoir properties. By integrating rock physics and well calibration, we enhance quantitative interpretation and reduce drilling uncertainty, especially in subtle stratigraphic and low-contrast plays.
Independent seismic processing QC ensures technical accountability throughout the project lifecycle. We review processing flows, parameter selection, velocity analysis, amplitude preservation, and final imaging quality. Acting as a technical advisor, GTN safeguards data integrity and ensures contractor outputs meet both industry standards and geological objectives.
