Geo Applications offers application of DMT seismic tool on clients own seismic data in order to significantly improve interpretation and increase amount of information gained from seismic data. Special combination of DMT and 2D seismic surfaces, DMT Trend Surface provides unique chance to identify structures lost between 2D seismic lines. Realization of trend surface interpolation is possible only with DMT data.

CORE BENEFITS OF DMT SEISMIC TOOL

Seismic refinement

  • Resolve uncertainities in seismic interpretation
  • Sub -basalt and sub-salt interpretation

Examples of Core Benefits

Following examples show the core benefits from exploration projects worldwide. The credibility has been verified by 2D seismic data.

Advanced interpretation of existing seismic data based on DMT

In many areas, seismic exploration reached its limits. One of the example, where additional methods are needed, is the sub-basalt exploration. Using the connection between the DMT technology and seismic data, numerous promising structures might be found below basalt layers.

*Accurate detection of elevated basement below basalts by DMT technology.

Tracking of geological structures out of the 2D seismic data

Resolution of DMT technology has potential to identify promising structures in sedimentary infill. Using limited number of existing data provided by our customer, Geo-Applications can track those promising structures to provide more accurate focus in the next exploration stage.

DMT Trend Surface

Trend Surface is commonly used tool in Petrel software. Its main usage is in numerous geological situations, when horizon correlates with base conformable horizon, but its reflex is not clearly visible in the whole area of interpretation. A similar approach was used by Geo-Applications to correlate DMT and basement surface. High level of correlation between the DMT surface and basement is an absolutely necessary prerequisite.

Example from UK Continental Shelf illustrates the difference in data value, if only one 2D seismic line is used (pic. a and b) and if the same line is used together with DMT Trend Surface (pic. c). Credibility of the results is presented in pic. d, where interpreted horizons on other 2D seismic lines are displayed together with DMT surface.

*Example of DMT Trend Surface from North Rona basin (UK Continental Shelf). Picture (a) shows one seismic line used for interpolation of basement surface (b) from this seismic line. Significant improvement of interpolation is achieved when DMT Trend Surface is used (c). Credibility of DMT Trend Surface was proved by additional seismic sections (d)
