Our ML solutions are here to streamline the processes for your individual business needs and to provide valuable data insights.
ML Fault Interpretation
Fault interpretation is one of the most difficult tasks within a structural interpretation workflow.

Geoplat developed the technology can help to significantly reduce time and resources spent on building a geological model. The use of machine learning based on deep neural networks allows to calculate fault probability distribution, extract surfaces, and eliminate interpretation uncertainties.

The Challenge

Commonly, creating a fault model and tracing faults is a very time-consuming process which requires a detailed understanding of geological characteristics of an area. An interpreter often has to run automatic interpretation workflows with multiple iterations depending on various geological and physical factors.

However, the capabilities of existing fault auto tracking techniques have serious limitations. Some challenges around automatic interpretation are still not resolved: poor data quality, regional and local discontinuity, volume size, reverse or listric faults.

Our Solution

Geoplat AI calculates image segmentation based on previously trained neural network datasets.

Our new generation convolutional neural network is trained on data samples covering multiple fault segments.
During the training process, the neural network generates a fault database that includes presence signs and identifies presence patterns in geological structures.

the initial seismic volume is automatically divided into sets of segments by Geoplat AI. The probability of fault presence at each segment point is automatically calculated based on a set of features generated during the training process.

There is also an option to customise the neural network by training it through manual fault labeling. User’s input is being added to the training set to retrain the network which changes the resulting model.

Finally, the algorithm automatically acquires surface groups using the calculated probability field, enabling a user to further customise the fault extraction parameters.

Application

— Obtaining a detailed fault
model framework

— Generating a fault probability field from the data that highlights fault distribution for all disconnected types within the entire seismic dataset

— Automatically extracting fault surfaces

ML Horizon Interpretation
Horizon interpretation is the core process in understanding the structural features of a geological profile and conduct reliable dynamic seismic analysis.

Geoplat offers a new approach to address automatic horizon tracing. You can trace a single horizon or the whole set, preserving complex fault structures and regional geological features.

Automatic interpretation of structurally complex horizons
The Challenge

The quality of horizon tracking is one of the key challenges in seismic interpretation.

It is also one of the most time-consuming tasks.


Nowadays there is a large number of auto tracking algorithms available. However, addressing a structural interpretation workflow in a complex geological environment still poses considerable technological limitations. This drive both project timings and costs up.

Our Solution

Geoplat AI allows to clean a dataset using machine learning capabilities. Our new generation convolutional neural network is trained on hundreds of thousands of unique synthetic datasets covering a large number of noise effects and types causing artificial seismic responses.

The trained neural network helps to improve the seismic data quality while maintaining the correct amplitude ratio: amplifying the visual display of fault zones, removing noise, restoring ‘removed’ reflections, smoothing effects, etc.

The algorithm picks the contours corresponding to the horizons on the predicted LGT (local geological time) section.

It provides an effective solution to the problem of auto tracking on different kinds of seismic data, preserving input data specifics (including multiple fault zones and complex horizons).

Application

— Automated interpretation of seismic horizons using the following signal features: peaks, troughs, zero crossings

— Automated tracking of stratigraphic horizon sets within a selected interval

ML Seismic Data Conditioning
Low quality seismic datasets often makes it difficult to build a structural framework
and predicting pay zone properties.

Machine learning algorithms developed by Geoplat provide a powerful workflow for interactive and intelligent data conditioning of post stack seismic data. It enables getting instant results considerably saving time on defining functions and workflows.
Increase seismic image quality
Improve the signal to noise ratio while
maintaining vertical resolution
Reduce time spent on parameterization
The Challenge

When processing the seismic data, the desired result is a geologically sound seismic profile, laterally and vertically balanced and with a high signal to noise ratio.

There are many different filtering techniques available to address various types of noise and to improve the quality of seismic data in general. However, dealing with filter settings is time consuming and often gives insignificant improvements in results. Changing the settings may also distort seismic amplitude and frequency spectrums. Thus, selecting optimal post stack procedures in each specific case is a common challenge that is hard to tackle.

Our Solution

Geoplat AI allows to clean a dataset using machine learning capabilities. Our new generation convolutional neural network is trained on hundreds of thousands of unique synthetic datasets covering a large number of noise effects and types causing artificial seismic responses.

The trained neural network makes it possible to improve the quality of seismic data while maintaining the correct amplitude ratio: amplifying the visual display of fault zones, removing noise, restoring "removed" reflections, smoothing effects, etc.

Application

— Removing irregular noise

— Improving the signal to noise ratio

— Boosting the visual expression
of fault zones

ML Salt Bodies Delineation
Common interpretation methods are usually unable to determine the exact positioning of salt body’s boundaries including its top and base.

Our innovative machine learning approach helps to generate a unique volume attribute that predicts the distribution areas of salt layers.


Reduction of misinterpretation
resulting from human bias
Automatic extraction of salt boundaries, including the top and base
Additional seismic attributes
to QC salt interpretation
The Challenge

Accurate salt body interpretation (and other similar stratigraphic objects) usually presents a complex challenge for geoscientists. Extreme dip values, doubtful horizon interpretation (including multi-Z cases), velocity anomalies and poor reflectivity data - all these factors contribute to uncertainties in interpretation.

Our Solution

Geoplat AI generates a salt probability attribute volume based on our
machine learning algorithm.

The algorithm uses a neural network trained on real data. The labelled data
generates a reference dataset that outlines defined top and base positions of
a salt body accurately.

Our new generation multilayer neural network compares fragmented data areas during the training with the desired features. It then assigns the salt probabilities to the original volume segments.

Geoplat AI machine learning algorithm divides the source data into segments, so the trained convolutional network applies a similar procedure and builds a 3D model.

Application

— Automatic horizon interpretation optimised for salt build-ups stratigraphy

— Stratigraphic horizon slicing

ML Channels and
Sand Bodies Detection

The problem of extracting subtle changes from the reflectivity data is often associated with various types of sedimentation responses. Sometimes there is insufficient detail to detect the entire object within the interval formed in the same geological period.

Geoplat AI can generate a complete probabilistic model to detect channels and other geological objects in the entire seismic volume.

of reflectivity expression
The Challenge

In the typical geoscience interpretation workflow, the task of identifying geobodies in the seismic data (channel bodies, bars, fans, etc.) could take a considerable amount of time, depending on data quality and geological uncertainty.

Traditional multi-attribute analysis techniques combined with RGB blending (or other blending variations) allow to identify geological objects in the seismic volume with a reasonable degree of accuracy. However, this approach has major disadvantages, such as false probabilities and the need to run complex and often

time-consuming attribute calculations.

Our Solution

Geoplat AI provides automatic identification of volume attributes that contain values of geobody’s probability distribution.

The main principle is similar to the salt body extraction workflow: it uses a new generation multilayer convolutional neural network which supports a deep learning process on the pre labeled data samples to identify specific objects
like channel bodies.

Based on Geoplat’s technology team experience, this algorithm helps to evaluate areas of interest even in extremely large seismic volumes. It can also be used as a QC tool.

Application

— Probabilistic predictive modelling for channels, sand bodies and other geological objects

— Detailed interactive interpretation

— Automatic geobody extraction
