RADEXPRO PLUS SOFTWARE FREE DOWNLOAD

Their support is excellent. As we can see from the flow structure and the names of the flows, offset VSP data processing before migration is done generally in the same way as zero-offset VSP data processing — data are loaded, first arrivals are picked, components are oriented towards the source point, deconvolution parameters are tested, and a reflected wave field is selected as a result. Now, without closing the Screen Display window, go back to the flow, uncomment the Deconvolution module and run the flow once again. The tutorial covers all standard stages of basic VSP processing, from data input to building a velocity model, tying VSP data to seismic survey data and printing out the results. As a result, the header editor window should look like the following: This includes making sure that the VSP traces are recorded at the same sampling interval as the seismic data, and that they have the same length and similar frequency content.

Information on the theoretical background of VSP and used processing procedures can be found, for example, in the following literature: Save the pick under the name of decon gate. Several algorithms for wave—field separation Convenient velocity modeling tool. We use RadExPro mostly for softwrae analysis as it is highly versatile and gives the user flexibility to build their own custom workflows using a variety of modules available.

It is a basic guideline describing the concept of RadExPro processing projects and giving a step—by—step instruction of how you can create a project plud load seismic data into it which is the very first step in RadExPro before you start any seismic processing.

Llus that are already in the flow can be moved up and down by dragging them with the mouse. Click the Axis button to set up axis parameters.

RadExPro – StableWAREZ

Calculation of various seismic QC attributes for shot gathers and receiver gathers Calculation of combined attributes, their display and analysis on linked cross—plots and histograms. Use the following parameters to obtain a migrated VSP section: The software is both efficient and reliable, and the support provided by Deco Geophysical is excellent. Picking P-wave first arrivals — fbpick Create a new fbpick flow consisting of the following procedures: Testing deterministic deconvolution parameters — deconvolution test.

The software is developed since Convenient, functional and intuitive. Do this by specifying the appropriate value in the New trace length field of the Trace Length module.

RadExPro 2016.3

To determine the amount of shift, you can select the rsdexpro data using the mouse and interactively move it up and down. Seismic reflection CDP data processing.

Building a corridor stack trace — cor stack trace and — cor sum The corridor stack trace is created by stacking the data in the specified window along the first arrival travel time curve. The resulting flow should look like the following: To do this, we will first introduce static corrections to bring the wave to the vertical line, then perform trace amplitude balancing Trace Equalization in the window containing the direct wave, and finally return all waves to their correct times by applying inverse static corrections.

Create a new flow and name it — cor stack trace. Each shot is read only once, to avoid network overload.

The streamers sofrware towed at around 12 m to pls deghosting and reduce the noises.

Tutorial on VSP Data Processing in the RadExPro Plus software

As we can see from the flow structure and the names of the flows, offset VSP data soctware before softqare is done generally in the same way as zero-offset VSP data processing — data are loaded, first arrivals are picked, components are oriented towards the source point, deconvolution parameters are tested, and a reflected wave field is selected as a result. The depth selection range of was chosen to eliminate the uppermost traces with high amount of noise corresponding to cable depths up to m.

Set the selection range in the Selection field: Using two picks, select the window for building a corridor stack trace as shown in the picture below: In general, the procedure of reflected wave separation consists of picking a travel time curve for a noise wave any wave other than the reflected onebringing the noise wave travel time curve to the vertical line using static corrections, subtracting this wave from the wave field using a two-dimensional spatial filter, and introducing inverse static corrections.

The right part displays a library of available routines modules grouped by their functional nature. In this flow we will read the NMO-corrected reflected P-wave field, select the interval along the first arrival travel time curve from the field using top and bottom muting, stack all traces to create a single trace, equalize the amplitude along the trace, and save the obtained results.

By the way, if you place the cursor in the appropriate column and click Set column, the column number will be entered automatically. When we add softwarw module, a dialog box will open, prompting us to specify the data reading parameters.

To do this, we will construct a flow consisting of the following procedures: Demultiple of high—resolution marine seismic data. Fugro use RadExPro globally for the offshore quality control or our seismic data. Detailed information on module parameters as well as an overview of other functions offered by the RadExPro can be found in the RadExPro Plus User Manual available for download from our website.
