In this paper, we present a new workflow for interpreting and imaging geomorphological features from seismic data not readily resolved using conventional techniques. The workflow combines a novel interpretation technology using a Relative Geological Time (RGT) model and spectral decomposition imaging. A case study demonstrates the process, in which an interpreted sequence stratigraphic framework is established using a RGT model-derived thickness attribute. This then constitutes the framework for extraction of geobodies, from spectral decomposition cubes, to establish and interpret the environment of deposition.

Fault and Top Seals: From Characterization to Modelling | Year: 2012

A new workflow to enhance seals and faults from the seismic imaging is proposed. Whereas most of the proposed methods for the characterization of seals and faults are obtained from seismic attributes, we have used a novel method based on a geological modeling from the seismic. From this model, new kinds of attributes can be derived to enhance sequence stratigraphy, faults, seals and traps. By computing the vertical derivatives of the geological model, also called the "Thickness" cube, it reveals the instantaneous variations of the geological layers in the volume on each seismic voxel. It is sensitive to the convergence and divergence of the geological horizons and therefore appears to be particularly well adapted to reveal traps, seal, spatial distribution of reservoirs. The fault imaging is obtained from the computation of 3D derivatives of the geological model, which shows a detailed detection of faults even in zones with a low signal noise ratio. Applied on the block F03 in the North Sea, this method has proven to be fast and efficient to evaluate prospects for well placement application and also maximize chance of success in exploration.

Sequence stratigraphy in the seismic interpretation workflow helps in the understanding of the basin analysis and the spatial distribution of reservoirs, seal and source rocks. Classical methods consist in identifying seismic discontinuities corresponding to the reflection terminations downlap, toplap, onlap, and truncation to define stratigraphic sequences and their system tracts. Such task is a labour intensive process mainly based on a limited number of auto-tracked horizons. Recently new approaches have been proposed to optimize this workflow. In this paper, we propose to analyze the thickness variations of a geological model, computed with a global approach based on a minimization process between the seismic relationships Pauget et al 2009. Given the fact, the geological model is continous; the variation of the thickness can be computed for any seismic voxel. The thinning zones of the geological model enhance stratigraphic discontinuities and provides to the interpreter a high level of precision in the identification of the sequences. We have applied this method on the block F3, located in the Dutch sector of the North Sea, presenting relevant large-scale sigmoidal bedding. The analysis of the thickness attribute enhanced zones of convergence of the seismic reflections packages corresponding to the observed downlaps and toplaps. A sub division into stratigraphic sequences could be achieved by mapping and thresholding the thickness values. Convergence zones of the different reflection packages were modeled in three dimensions for a better understanding of the spatial depositional process. This case study has shown the rapidity, robustness and the accuracy of the geo-model approach in the analysis of the stratigraphic sequences. These results suggest that the method could be used to optimize the level of detection of subtle traps, seals and reservoirs, at an early stage in the interpretation process. © 2011 Society of Exploration Geophysicists.

Being a mature basin, the UK Central North Sea area has benefited from the acquisition over time of extensive 3D seismic coverage, both on a speculative and proprietary basis. Maersk Oil UK has acquired data covering most of the Central North Sea over a 15,000 km2 area. Even though such a huge data set brings real advantages in facilitating exploration and new venture efforts, extracting the information and utilising it in a timely manner is challenging. In this work, the interpretation was carried out by applying a novel approach, which generates a 3D Relative Geological Time model directly from the seismic to leverage information contained in large-scale seismic data. The outputs of this workflow applied in a short time frame of 8 weeks were used for different applications such as shallow hazard assessment; strataslicing along seismic attributes; delineation of geological features and basin modelling. This approach has revealed lots of potential from a regional standpoint for further more in-depth and focused interpretation work.

This paper presents the application of a novel method, based Relative Geological Time (RGT) model, for the interpretation of the block K05, a large and complex zone located 120 km offshore Netherlands. The aim of this study was to understand the stratigraphic evolution of the zone, the fault network geometry and the rock properties distribution, in the reservoir level. The RGT method is a computer aided workflow using a grid, where each node is an elementary horizon patch with a constant size. The main challenge consisted in refining the model results below the salt, where the reservoir level lies, by using the well markers. A thinning attribute, derived from the model was used to delineate the stratigraphic units in the reservoir level (middle Permian). Subtle fault detection was done by using the deepest descent gradient, unseen with classical seismic attributes. The fault throw distribution, mapped onto fault planes with a very high resolution, has revealed a compartmentalisation of the reservoir level. The interpolation of acoustic impedance logs, using the RGT volume, allowed to identify heterogeneities related to fine scale gradual deposits variations, in the reservoir level.

After three years of intensive R&D efforts, a novel approach is proposed in seismic interpretation to exploit the three dimensionality of the seismic data throughout the seismic volume. Instead of interpreting individual seismic events this method enables interpreters to build a stack of horizons that follow every event. User intervention is still needed, for example, to ensure that the correct jump correlation is made between horizon patches on opposite sides of a fault. Once an interpreter has identified the correlations, the method will then automatically make an updated and optimized stack of chronostratigraphically indexed horizons. Such technology reduces time cycles, helps in the identification in the geological prospects and minimizes risk for drilling decisions in the E&P process. It has been tested on various case studies to quickly leverage information contained in seismic data at different scales. This approach is ideal when you need to rapidly evaluate a new area from top to bottom.
