Geo Suite Tool Kit

Geo Suite Tool Kit

Geo Suite comprises a total of 11 interlinked tools running on a Microsoft Windows platform (6 for O & G seismic QA/QC applications).  The tool kit is designed for the geo-spatial geomatics engineer and is specifically tailored to perform operations on data types related to oil and gas exploration and development.  The tool kit provides a series of functions that ensure the full geodetic integrity of data is maintained in compliance with standard international practices and uses recognized algorithms and geodetic authorities to conduct its data manipulation.

The main features of Geo Suite tool kit include:

Recognizes all common data types with a geo-spatial content associated with exploration and development activities, for example:

  • 2D Seismic positioning data (All UKOOA / OGP P1 exchange file formats)
  • 3D Seismic positioning data (All UKOOA / OGP P1 exchange file formats, SEG-Y format)
  • Full fold bin grid definitions (All UKOOA / OGP P6 exchange file formats)
  • Well surface positions (standard .txt or .csv formats)
  • Well bore surveys (.LAS and UKOOA / OGP P7 exchange file formats)
  • Block boundaries and concession blocks (standard .txt or .csv formats)
  • Pipeline and platforms (standard .txt or .csv formats, .shp files)
  • Geo hazard survey positioning data (All UKOOA / OGP P1 exchange file formats)
  • Raster and Vector mapping formats (.dxf, .shp, .jpg, .bmp, .GeoTIFF, .TIFF, .txt, .csv, .xls, etc.)
  • Digital terrain models (USGS format, GeoTIFF)
  • Full recognition of EPSG codes and ISO nomenclature.

Geo Suite Tool Kit is essentially divided into three sections:

  • Geo Suite Essentials – providing all geodetic parameters and computations.
  • Geo Suite Mapper (& database) – providing  mechanism for import, storage, viewing and export of the data sets recognized within the inventory.
  • Geo Suite Seis QC – providing the QA/QC for data integrity checks of seismic related data sets.

 

 

The QC functionality aims to directly determine the suitability of seismic positioning data associated with the seismic trace data.  Although further details of the QC functions are provided in the link above the salient details of these utilities are given here:

 

Seis Line 

It provides QA/QC functions to check seismic positioning data acquired along a pre-plot survey line regardless of the number of seismic streamers or sources being towed.  Therefore, the QA/QC functions suites both 2D and 3D seismic surveys for land and marine environments, and caters for towed, OBC, OBN, Geo Hazard Surveys.  Its functions include:

  • Full QA/QC analysis of the imported seismic navigation files, line by line and event by event.
  • Analysis is performed for the following general categories of error:
    • Increment
    • Distance
    • Azimuth
    • Interval (time based)
  • Further analysis also determine duplication with respect to
    • line names
    • point numbers (source and receivers)
    • point coordinates (source and receiver)
  • Error type are color coded within the tables, graphs and text reports for ease of identification.
  • QC checks are performed against a set of user-defined tolerance levels.
  • Full QC analysis of receiver records associated with the 3D marine streamer data (3D Seis), including:
    • Feathering
    • Streamer and source separations
    • Streamer and source depth control
  • Provides map and graphical displays (time series plots) for all aspects of the data.
  • Provides editing functionality to remove errors identified from the QA/QC analysis.
  • The Export wizard enables the user to export navigation data.  These features include:
    • Selection of industry standard data exchange format to which the data will be written
    • Selection of coordinate reference system to which the data will be referenced
    • Inclusion of header blocks to compliment to data blocks
    • Ability to select which lines within a multiple line data set are exported.

Seis Grid

  • Capable of defining 3D seismic Bin Grids – by  any one of the following combinations:
    • UKOOA P6/98, P6/11 formats
    • 4 points (inline, xline, x, y, CRS), 3 points  (inline, xline, x, y, CRS),
    • 2 points  (inline, xline, x, y, CRS) where the two points are not on the same inline or xline and
    • 1 point  (inline, xline, x, y, CRS) + survey azimuth, inline/xline spacing, survey orientation (left or right handed).
  • Bin Grid QA/QC
    • Determine rectilinear nature of grids.  If not, indicate the magnitude of resulting uncertainty
    • Compute bin grid attributes:  inline/xline spacing, survey azimuth, L/R handedness
    • Determination of error in redundant information and computation of  best-fit grids
    • Reprojection of corner points to a new CRS.
    • Readjustment of corner points to rectilinear grid (what-if scenario testing)
    • Display bin grid corners against a backdrop of cultural info
  • Derive Bin Grid from Navigation File
    • Import a navigation file which could be all bin center locations, line end points, or a collection of points across the survey
    • Compute a bin grid which best fits the data (least squares)
    • Display error plot showing amount of difference between bin grid results and input data locations
  • Visualize Bin Grid and 3d Survey Subsets
    • Plot bin grid based on 3/4 points that are entered, or based on a user defined polygon, or based on navigation file extents
    • Allow user control of display parameters (decimation, labeling, etc).
    • Plot over a backdrop of cultural data (including ability to use live web service base maps.
  • Compare 2 Bin Grids
    • Compare / Display differences between two bin grids entered by the user
  • Export Bin Grid / Nav File
    • Write fully populated P6/98 and P6/11 files
    • Write fully attributed Load Sheets
    • Export Grid as Key files
    • Export Grid as SQBINR parameter file
    • Export a P1 navigation file with full headers allowing user control over decimation and clipping to a polygon.
