Seismic-driven Fracture Analysis from Full-azimuth Subsurface Angle Domain Data: A South Texas Case Study
Featured technologies:  QSI, EarthStudy 360™

High density full-azimuth seismic acquisition may record data revealing information about subsurface fracture and stress orientation and intensity. This information is useful for prospecting tight reservoirs.

This session will show a methodology for extracting fractures from a South Texas dataset. In two formations with seismic-scale fracture system (Austin Chalk and Olmos Formations), the vertical fractures appear to be associated with the major tectonic faulting that occurred in this area. Identifying those local areas within a play with higher probability of natural fracture corridors can be vital for asset portfolio management and horizontal well placement.

The entire fracture characterization process is carried out in the Local Angle Domain (LAD), a domain that describes subsurface image points by two polar angle systems that capture full-azimuth reflectivity and full-azimuth directivity. The data parameters are measured in situ over all reflection angles and azimuths, making data more relevant for fracture analysis.

What you will learn about in this lecture:

  1. Fracture analysis methods
  2. Seismic velocity variation with azimuth
  3. Seismic imaging in the Local Angle Domain

Improving your Structural and Stratigraphic Interpretation using Seismic Attributes
Featured technologies:  SeisEarth™, Seismic Attributes

Recent advances in seismic acquisition, processing and visualization enable us to extract more value from seismic data than ever before. Physical attributes may be used as direct hydrocarbon or lithologic indicators, while geometric attributes facilitate the definition of both the structural and stratigraphic framework of the seismic interpretation. Fast on-the-fly computation, multi-volume visualization, image processing through advanced merge and voxel opacity, are some of the techniques that enable the efficient use of seismic attributes.

In this workflow-based presentation, we will show how geoscientists can use Emerson’s latest technologies to provide details of the structural, stratigraphic, and fluid framework not readily visible in normal seismic amplitude image,s to derive new insights into the subsurface.

In this lecture, you will learn about:

  1. Extracting geological information not readily visible in regular seismic data
  2. Visualization techniques for the efficient use of seismic attributes
  3. The Principal Component Analysis workflow

Enhanced Seismic Interpretation from Diffraction Energy​
Featured technologies: EarthStudy 360™ + Epos™-based seismic interpretation software

Although diffracted energy is recorded during data acquisition, it is suppressed by conventional processing and standard imaging algorithms, where summations and averaging processes are applied, resulting in the loss of high-resolution structural information.  Current processing workflows rightly focus on high specular amplitudes to enhance the continuity of seismic reflection events, thus improving the structural mapping of the subsurface.  Consequently, in a traditional seismic interpretation workflow, some derived discontinuity attributes (e.g. coherence, curvature or fault likelihood) may carry only partial information.

This presentation will describe the decomposition of the full wavefield, and the benefits of separating reflection and diffraction energy fields through various case studies, to provide geoscientists with high-resolution subsurface images containing different types and scales of discontinuous geometrical objects. The objective is to leverage the traditional seismic interpretation workflow by integrating information relative to diffraction energy like any another poststack attribute to be interpreted.

In this lecture, you will learn how to:

  • Decompose the full wavefield and the benefits of separating reflection and diffraction energy fields.
  • Leverage the diffraction energy recorded at data acquisition to improve seismic interpretation.
  • Obtain high-resolution subsurface images.

Deep Learning for Automatic Geological Feature Detection and Classification
Featured technologies:  EarthStudy 360™, SeisEarth™

Modern 3D data-rich surface acquisitions sample an equally rich set of subsurface information, resulting in different wavefields associated with different subsurface features and conditions. These wavefields carry signatures related to fractures, faults, edges, points, and other structural discontinuities, features not always easy to resolve because of size and low illumination energies. When isolated, these wavefields can be used to produce feature-targeted images of unprecedented resolution and clarity.

To capture all these wavefields, a full-azimuth prestack depth imaging procedure is used that maps data into a multi-dimensional prestack directional angle gather consisting of thousands of traces (directions) illuminating each subsurface point from a rich spectrum of angles. When combined with Principle Component Analysis (PCA), deep learning filters can be applied to these directional gathers to extract subsurface features (e.g. faults, stratigraphic edges, karsts) that are often lost or heavily attenuated with standard seismic processing and imaging methods. 

In this lecture, you will learn about:

  1. Resolving low energy faults and edges
  2. Applying Principal Component Analysis (PCA) to decompose seismic data
  3. Applying deep learning to classify and extract geologic features such as reflectors, edges, faults, and organized noise from multi-dimensional seismic data

A Flexible and Robust Time-Depth Conversion Workflow Using Various Velocity Sources
Featured technologies:  Explorer™

Velocity modeling is a critical step in accurate time-to-depth conversion and hydrocarbon volume estimation. Consequently, a comprehensive and intuitive solution fully integrated into the main interpretation platform is crucial for workflow productivity.

The time-depth conversion process is required in several steps of typical G&G workflows, such as structural mapping and volumetric calculations, QSI activities, well log data domain conversion, and well planning.  To support these multiple objectives, a single, shared window implementation is required to build velocity models consistently, combining different velocity sources in a more straightforward way. 

In this presentation, we will show how the Global Velocity Model can enable velocity workflows that use many kinds of velocity information, spanning simple to complex geology, in cases where there are few or no wells to many wells, and from a single seismic survey to multi-survey cases.

In this lecture, you will learn how to:

  • Create velocity models through an easy-to-use, one-window interface.
  • Define and QC a velocity model using various velocity sources
  • Adjust your velociy model to Checkshots

Enhancing Reservoir Prediction by Strengthening Seismic Attribute Analysis with a Waveform Classification Workflow​  
Featured technologies:  SeisEarth™

The waveform analysis and classification technique is useful for extending attribute analysis to determine geologic similarity and variability from seismic data. Attribute analysis assumes that the attributes used are descriptive reservoir changes. While true generally, it alone can lead to false positives through insufficient risk reduction in exploration and development; and false negatives, making potential prospects become overlooked. Waveform classification takes a different approach, as it analyzes the attribute waveform throughout the interval before reducing it to one value. The results provide a richer understanding of reservoir rock properties and spatial delineation. 

In this lecture, you will learn how to:

•    Reveal more geology from seismic data
•    Expand seismic investigation toolkit
•    Improve confidence in reservoir prediction and delineation

Seismic Depth Imaging in the Presence of Azimuthal Anisotropy
Featured technologies:  EarthStudy 360™

Orthorhombic velocity modeling and imaging provide key alternative technologies for recovering natural fractures. However, the determination of orthorhombic parameters is challenging and requires special methods to obtain in-situ azimuths with rich sampling. Additionally, proper orthorhombic imaging in the depth migration domains, rather than time migration domain, requires interval parameters instead of simple effective parameters.

In this session, we present a methodology where the entire orthorhombic imaging process is carried out in the Local Angle Domain (LAD), a domain that describes subsurface image points by two polar angle systems that capture full-azimuth reflectivity and directivity.

In order to build an orthorhombic velocity model for imaging and fracture characterization, other workflow steps are needed to ensure a more stable and reliable outcome. These include shallow velocity modeling, surface noise attenuation, and data regularization for low fold acquisitions. This session will also cover other processing steps that are pre-requisite for a successful outcome. 

In this lecture, you will learn about::

  • Image quality uplift post-orthorhombic imaging
  • Advantages of seismic imaging in the local angle domain

Optimizing Petrophysics to Solve Mineralogical Complexity in Conventional Reservoirs​
Featured technologies:  Geolog™

Petrophysical analysis provides vital input to most, if not all, geoscience workflows. While a deterministic approach to formation evaluation will provide values for shale volume, porosity and saturation, taking into account mineral and fluid volume complexity can offer more insight into the distribution of your petrophysical properties.

In this session we will look at:

  • The theory behind the Multimin optimized petrophysical method in Geolog™
  • Utilizing the Monte Carlo method as part of the Multimin workflow
  • Probabilistic model switching

Get More from Your Image Logs : Borehole Image Processing and Interpretation 
Featured technologies:  Geolog™

Borehole image logs provide very high resolution images of the borehole. We often use this data to interpret structural dip of bedding, fractures, breakouts, etc. Beyond looking at the structural geology, borehole image data can also give us a better understanding of rock texture that can lead to deeper insight of the depositional environment of the reservoir.

In this session, we will look at:

  1. The borehole image processing workflow
  2. Image upscaling for statistical and facies analysis
  3. Textural analysis using 2DSOM and MRGC

Well-to-Seismic Calibration: How to Get the Most from your Seismic Data
Featured technologies:  SeisEarth™ 
Well-to-seismic calibration is a critical step for appropriately mapping logs, markers, and the well trajectory to seismic data. It’s a means of understanding the seismic waveform relation to the subsurface geology and selecting meaningful seismic events to pick horizons.

A synthetic seismic trace (synthetic seismogram) is calculated from elastic property logs (velocity, density and time-depth) and a wavelet, then converted from depth to time. The synthetic seismogram is correlated and compared with seismic traces to determine a goodness-of-fit at the well location. You then calibrate (stretch & squeeze) the synthetic seismogram to improve the match with the seismic data.

In this lecture, you will learn how to:

  1. Avoid common pitfalls
  2. Incorporate a more rigorous approach to well-ties
  3. Improve results from workflows that rely on integrating well and seismic data

Well Bore Analysis, Geomodeling and Seismic Attributes for Enhanced Fracture Detection
Featured technologies:  Geolog™, SKUA-GOCAD™, Epos™

Maximizing hydrocarbon recovery in fractured reservoirs requires a deep understanding of the subsurface, fracture network connectivity, and the interaction between the matrix and fracture networks, whether fractures are naturally occurring or induced.This presentation addresses challenges, objectives, and responses from seismic, well and modeling by illustrating an effective cross-domain technology-based workflow for fractured reservoir imaging. Structural attributes paired with automatic fault extraction and RMO(z)-AVA(z) or diffraction energy detailed interpretation set the main framework, while wellbore fracture characterization sets the vertical resolution for the subsurface model to image the stimulated and natural fracture networks, support fracture and SRV analysis, and derive a realistic mechanical model.

In this lecture, you will learn how to:

  1. Define which seismic attributes are used to detect and characterize fractures
  2. Understand the geomechanical conditions (stress and strain) affecting oil and gas reservoirs
  3. Evaluate the impact of fractures for optimizing well placement and production
