Frequently Asked Questions

Q: How can I convert my picture files into JPG (.jpg) or GIF (.gif) format files?

A: If you have a workstation with:

GeoGraphix software, you can click on "Presentation" module and select .jpg as an output file format.

Seismic Micro-Technology software, you can put your montage output file into the Clipboard as a bitmap and then export the bitmap to a Corel Paint or other Photo program that can output a .gif or .jpg file.

Paradigm - SeisX software, you can save your file as a bitmap and then export to a Photo program and convert to a .jpg or .gif file.

A UNIX operating system with Schlumberger - GeoQuest or Landmark Graphics software using Solaris and Common Desktop Environment (CDE), you can click with the third button in an open area. Select Programs and then "Image Viewer". Import your image into the Image Viewer and then go to "File", "Save as..". Under "File Format:" select GIF or JFIF(JPEG).

(Your software vendor is working on the need to make .jpg and other format files straight from the software. You may want to call and ask your vendor if they have their new release for this situation, yet.)

Q: Can I send II&T CAD files (.dxf) to display my prospect with?

A: To save you on costs, please do not send .dxf files. If you do send .dxf files, II&T can convert CAD files (.dxf) to .jpg or .gif files using CPS-3 or GRASS. However, the .dxf file format is not properly implemented by many software vendors (i.e.;may not have the latest version), so II&T may have to send it out to a third party service company for conversion, which has the same software version that you used to write the file.

Q: Can II&T or I send graphical images by e-mail?

A: II&T can send images by e-mail as long as the image size is within the limits of one to five megabytes as set by each Internet provider. If you have a telnet server we can access we can upload or download files of at least several hundred megabytes. For security reasons, we do not at present allow outside persons online access to our network.

Q: What file formats can II&T read?

A: This question has two aspects: physical format, and logical format.

We can read: 8 mm tape (8200 or 8500 format, including XL), DLT tape (I, II, III, or IV), and CD-ROM (ISO9660 with Rock Ridge extensions. Note that neither Apple nor Microsoft adheres to these standards, but we can probably read your CD-ROM anyway).

Logical formats are more complicated. For seismic data, we can read genuine SEG-Y format from tape, and most tape images on disk, or tar tapes of disk images. We cannot read SEG-A, SEG-B, SEG-C, SEG-D or SEG-X. We probably cannot read "SEG-Y" data with ASCII headers instead of EBCDIC, or with a header other than 3200 bytes, or with trace data in some strange floating point format, or with no values anywhere in the binary header. We cannot read 3D seismic data from a SEG-Y file if we have no clue as to the geometry of the 3D grid (actually, we can, but you probably don't want to pay for the time it takes to do this).
Navigation data can be read from any ASCII (or EBCDIC -- but we have never seen one yet) file which gives X and Y values for surface points which can be related to trace number in some logical way. Note that the SEG-Y format does not include Surface Point number or Surface Point X and Y. If you think your file contains this information, it is a non-standard extension, and must be fully documented. Navigation data should refer to the data in the seismic file: if several line segments have been merged in processing, we need merged navigation data to match. We can merge navigation data, but we often do not have all the information we need to do so. 3D data does not need a navigation file, just three points defining the grid.
Well logs can be read in LIS and LAS format. LIS is an extremely complex binary format, originally designed for low density half inch tape, and well documented by Schlumberger. LAS is a straightforward ASCII format designed for MS-DOS floppy disks.
Cartographic data is most readily used in Tobin format, but other formats may be usable.
Horizon and fault data can be imported easily into most software modules provided they are supplied in ASCII files with X, Y, and Z values for each data point, provided the projection for the XY values is fully defined.
