Data Processing

Soliton team has designed a flexible workflow that provides for detailed analyses of EM and seismic data with high contribution to the decision-making process for well location.

From the early stages of feasibility to the final interpretation, it is critical to make use of all the available data.

Working closely with our customers, our overall goal is to produce an interpretation that is consistent with all the known geology and data types.

Integrating geophysical data types can provide information on a reservoir that is either not available using any one data type alone.

HREM  technology is still at a development stage and improvements related to all components (hardware, software, acquisition, processing and integration  techniques are common.

Data QC and Processing

QC Processing flow chart includes:

  • Re-format of input data to processing system format.

  • QC analyses

  • Navigation data processing.

  • Field transforms analyses

  • Apparent resistivity section design

  • Selective 1D inversion

  • Onboard processing hardware and software includes:

  • Computer     IBM-PC

  • High Resolution EM data

    Vibor ѻ, licensed program, that provides real geoelertric media modeling with any type of source impulse and  also processing in 1-D and 2-D format inversions.

    PrWork - application package that provides data processing for IP, TS, conversion to Excel, Seg-Y formats

    Received and preprocessed onboard data daily was transmitted to computer center via communication satellite system.

    Processing and interpretation of field data is carried out by computer center simultaneously with field work that has significantly reduced finishing of work time.
