EpiQC software aims to reduce this time while at the same time increasing QC resolution and hence confidence in the data integrity on land seismic projects.

The Field QC must be able to read and analyse all of the various files and formats. Purva punya marriage this is done the data is then usually cut and pasted into another spreadsheet created specifically for a particular project. Spreadsheet tables and charts are then manually adjusted to match the data for that day. This process can take some time depending on the complexity of the data.

The EpiQC software loads the file into memory, performs all necessary reformatting and then creates a spreadsheet perfectly matched to the data for that particular day. Typically the software can process tens of thousands of lines of data and then produce a spreadsheet in just a few seconds.

Different crew systems and formats are catered for by a settings table which is set up in a few minutes at the start of each new project. Crew data which requires only a single file can be checked in just two mouse clicks.

Press the Open File button clickselect the file click. EpiQC then automatically carries out all reformatting, processing and analysis required to produce the final charts, tables and reports that clearly identify errors and anomalies in the data. All EpiQC programs have a similar look and in almost all cases opening a file for analysis is the only user interaction required to start the reformatting, processing, analysis and display.

Some programs will also need a reference file but this too is simply selected by the user with no further interaction required. These modifications will invariably involve altering spreadsheet cell formulae, which is time consuming and error prone. EpiQC programs have been designed by identifying the aspects of the data that tend to change from project to project and then provide a table of settings which allow these differences to be accommodated.

The following image shows the settings for the Sensor Log Analyser program. All EpiQC settings forms have a similar look and all allow settings to be saved. The following pages give a brief description of some of the features and advantages of using EpiQC software as the standard set of QC Tools on a seismic project.

In the following charts the SMT Analyser shows how geophone specifications were improving as elements were replaced during string rotation. At the start of the project the elements were found to be within specification but tending toward the limit for the resonant frequency test. Failure of this test is an indicator of old elements.

As the project progressed the geophone strings were rotated through the camp. During this process 6cl6 tube data elements were replace with new ones. The chart below shows a marked improvement in resonant frequency with an overall trend closer to the specified 10Hz. The chart below shows the two sets of tests sorted by resonant frequency and overlaid on a single chart.

The chart clearly shows an improvement in resonant frequency after elements were replaced blue line. These two programs read the Sercel instrument test logs directly and provide a fast but detailed report in both text and graphical form. These logs are presented to the client as daily instrument tests. The second of the two daily instrument test analysers. The sensor analyser reads and analyses the geophone test data such as noise, tilt, resistance etc.

This program has the ability to sort the data into receiver line and point number, as shown in the chart below. This ability provides a good indicator of whether line problems are related to location.Wellbore data quality control and reporting. Petrophysical interpretation.

EpiQC Software Overview – The Programs Update

Logtek has established a very powerful and efficient organisation to handle large volumes of data without compromizing the quality of the final product.For example, we can directly load the file Waha8. This can be useful for very small volumes or to extract information from the file and trace headers in the file. It is not recommended to directly load large seismic data sets for visualization because they are normally much larger than the available system and GPU memory.

Note that there is an LDM converter Lewis structure for ncl2 specifically for SEGY files because it is often necessary to give the volume reader more information in order to correctly interpret the file. Also it is often necessary to store additional information in the LDM file header, for example the ranges of line and cross-line numbers.

The SEGY reader provides some convenience methods for retrieving essential information about a survey. For example the range min and max values and step size for inlines, cross-lines and time. The reader also provides a general mechanism for querying the SEGY file header and trace headers, which we will explain in the following sub-section. Given the correct range and step size we can compute the actual number of inlines, crosslines and samples.

This process is the same for any file format and reader, as explained in the previous sub-sections. NET and set the file name.

NET that we can use like the following code. For the Waha8. In fact by default we get 1 to 87 by steps of 1. The problem is that the SEGY reader expects to find the inline number at byte 5 tracr by default. For Waha8. In the next sub-section we will see how to adjust byte positions when loading a SEGY file. The getDataChar get data characteristics method returns the characteristics of the 3D data volume that the reader will extract from the SEGY file. By default this is an arbitrary bounding box computed from the voxel dimensions of the volume.

We will discuss in other sections how to use the actual survey coordinates and how to scale the time axis to give a more useful display. Remember that the SEGY reader loads traces into contiguous memory, so this is samples x crosslines x lines. The getP1P2P3P4Coordinates method returns the coordinates of pronest 2019 install corners of the survey as double precision 2D vectors. It also returns a boolean value indicating if the survey should be interpreted in a left-handed or right-handed coordinate system Note: not in the Java API.

In this case we expect P2 to be approximatelybased on the textual header. But by default the X value of P2 is returned as The problem, as mentioned earlier, is that the SEGY reader expects all trace header values to be integers as stated in the spec and these values are actually stored as floating point.

In the next section we will see how to adjust the data format. Finally, we might want to check what byte positions the reader actually used to determine the inline and crossline numbers. NET object which contains the byte positions of all the trace header fields. Use the getBytePosition method to get the position of a specific header field. As expected, we see that by default the reader is expecting the inline number at byte 5 and the crossline number at byteThere are more than modules allowing all usual steps of seismic reflection processing.

Hence will acoustic impedance be used for tying the logs to the near offset stack, and elastic impedance to the far offset stack.

You are getting prompted to select a project. Since this is the first project, a new one has to be created. Instead, the user gets prompted for this information. Note that the default sample rate is micro seconds, not ms. The CDP spacing is the same as cross-line spacing for this file. The value should be set to 25 m. The origin is the position of the first CDP for a 2D line.

In the last window appearing, the well position is tied to CDP number. As can be seen in the appearing window, the well is highly uncorrelated to the seismic data and the well needs to be shifted to match the strong peak. This peak is the top Cretaceous. The seismic window can be closed. A portion of the near offset stack is automatically shown on the log panel.

The red trace marks the well position. We start with correlation to the near offset stack and continue on with the far offset stack later. In the next window, the time and CDP range for wavelet extraction is assigned. The seismic data are muted above ms, and the well ends at approximately ms. The vagabond romance was located at CDP 37, so selecting the neighboring traces from 25 to 45 should be appropriate.

The extracted wavelet appears in a new window. Click the correlate button in the Elog main window. Elog now computes a composite trace from the neighboring radius of 4 traces on the near volume.

This trace is shown in red at the log panel. The blue trace needs to be scaled down to correspond to the composite trace. This can be achieved by the display options. This should result in the log panel.

The plot appearing suggests to shift the blue trace down. Also, due to the deviated path, it also needs to stretched. Note that the correlation coefficient hopefully increases. By applying a stretch from only one pick shifts the logs.

Picking more events stretches the logs. Note that the blue trace gets automatically updated with the new wavelet. The parameters shown here are only sample values. This process should be repeated with other values to obatin a better wavelet estimate.To properly display this page you need a browser with JavaScript support. SonarWiz 7. User Guide.
