Prestack Data Enhancement toolkit
Prestack Data Enhancement toolkit
The Sharp Reflections PRO toolkit, built for high-performance computing, brings processors and interpreters together to seamlessly QC and condition huge volumes of seismic data for specific interpretation purposes.
The PRO processing tools operate on full prestack gathers and on stacks, and let you quickly and flexibly optimize the reliability of your full-area seismic data—data that will be used throughout the life of the reservoir. No need to limit your working area.
Process, condition and QC full-fidelity prestack or poststack seismic data, and integrate with advanced interpretation tools, all on a single HPC-powered platform.
Working on a single software platform that integrates inversion, azimuthal or 4D time-lapse data, you have the power to run multiple conditioning iterations, and see for yourself the impact on your final results, in minutes or hours rather than days or weeks.
Extract and explore the amplitude evolution on any event throughout the processing workflow, without compromise. Link stacks, full-fold gathers and map viewers, and explore all angles of new prospects. In development and producing fields, calibrate to new well data and remove noise on repeat seismic surveys to track fluid movement with greater precision.
Benefits
Quickly and manageably assess data quality, and interactively improve pre- and poststack data using the power of HPC
Tune parameters, explore possibilities by merging processing and interpretation expertise, up front.
Gain confidence in your prospects by performing volumetric QC of conditioning results at the well level, on layers, or on the full area.

PRO toolkit
Unlocking the value of multi-dimensional data
Generate complex processing workflows and automate execution
Make repetitive tasks easy and efficient. When exploring a huge dataset, you want to try different parameters, and “what if” scenarios. The workflow manager makes it easy to set up and repeat tasks.
Try, try again—until you are satisfied that you have the best results.

The data enhancement toolkit includes a range of advanced tools and techniques for improving the quality, accuracy, completeness, and usefulness of data. Some common examples of advanced data enhancement tools include
- Demultiple
- Random noise reduction
- Gather flattening
- AVO-compliant scaling and wavelet harmonization across offset or angle
- Q compensation and spectral shaping
- Time-depth conversion
- Conversion of offset gathers to angle gathers and vice versa

Sharp Reflections software makes it easy to generate workflows in batches of unlimited volume size. It provides a powerful and intuitive tool for processing and analyzing large datasets. After interactively testing conditioning processes, our software provides a user-friendly interface and intuitive workflow generation tool that allows users to create and manage complex processing workflows.
In addition, the software includes built-in optimization features and scalable architecture, allowing it to handle large volumes of data efficiently and effectively.
Does the PRO toolkit truly allow me to work interactively?

In-memory architecture is particularly well-suited to interactive testing and QC processes. In-memory systems store data in RAM (random access memory), rather than on a disk or other slower storage media. By storing data in RAM, in-memory systems provide fast access to data, allowing for near-instantaneous processing and analysis of large datasets.
As a result, you are able to
- test and validate data quickly and efficiently to ensure its accuracy and completeness
- perform real-time analytics and other time-sensitive tasks
- rapidly create iterations and test new data models and algorithms.
Can I process only narrow azimuth datasets? How do I condition my WAZ datasets?

All the algorithms have been extended to azimuthal (wide azimuth datasets), time-lapse data, onshore and offshore, providing you with a smooth experience.
The processing tools are adapted to handle directional data, including common offset vector and common offset/common azimuth data. These datasets may be used to map the orientation and properties of subsurface geological features, such as fractures and faults.
The processing toolkits are also adapted to multivintage datasets, giving access to extra features to ensure full time-lapse conditioning, which can then be used to monitor changes in subsurface properties, such as fluid pressure, temperature or seismic activity over time.
Can I process my data if I only have angle stacks or does your software work only with prestack gathers?

Improving your QI or inversion attributes from angle stacks is also possible with the Sharp Reflections PRO toolkit. For example, noise reduction and stack alignment algorithms can be used to improve your final attribute quality. You can use the flexibility and the interactivity of the software to get the best of your input data whatever it is, from offset gathers to stacks.
How can I QC my dataset on the full area, and be sure that the data is optimal not only on my test line?

Thanks to its in-memory architecture, Sharp Reflections software allows you to do interactive and extensive QCs. The QC maps can be linked to prestack data to better assess the data quality and to better define the conditioning sequence.
Health checks are an important aspect of seismic data processing. They help to ensure that the data being analyzed is of sufficient quality and accuracy to support reliable interpretation and decision making. To assess the seismic data quality on the full area, health checks can be performed at various stages of the processing workflow.
Some key health checks that may be performed include the following.
- Noise and distortion analysis—to assess the level of noise in the seismic data, which can impact the accuracy and reliability of subsequent interpretations or QI studies.
- Data consistency and completeness—to assess the consistency and completeness of the seismic data, ensuring the AVO fidelity.
- Quality control of seismic attributes—to assess the quality of such attributes as amplitude, frequency and phase, to ensure that they are consistent and reliable across the full area.

The PRO toolkit can be used to get a better and a more reliable interpretation. It offers advanced noise reduction algorithms to attenuate random and coherent noises and help remove unwanted artifacts, resulting in higher quality seismic data.
The stack response can be enhanced by using time and spatially variant mutes, as well as weighted stack techniques to use only the data with the best S:N ratio.
How can I be sure that the data is fit for my QI or inversion study?

The PRO toolkit streamlines the integration of the conditioning with QAI and inversion workflows. It allows you to assess in real time the effect of the conditioning on final products. The high-performance speed of Sharp Reflections software means you can assess the effect of individual processes on the attributes used for interpretation.

Sharp Reflections turns huge datasets into assets instead of roadblocks. Our software helps clients explore their seismic data—every terabyte—to develop deeper, purer views of their reservoirs.
Sharp Reflections is the industry’s only software platform built on a powerful compute and display engine designed specifically for high-performance computing (HPC), on premises or in the cloud.
Our integrated platform enables users to start analyzing and interpreting seismic data as soon as processing begins. No information is wasted as users reduce uncertainty and fine tune their reservoir characterization to help achieve trustable exploration, drilling and production decisions.
