When combined with 3D seismic, geological models and appraisal well data, the outcome of this service is an improved estimation of the volume and distribution of hydrocarbons present within the prospect. These factors enable operators to establish, with greater certainty, whether the prospect contains commercially viable reserves.
The service has the potential to reduce the number of appraisal wells drilled, thereby producing significant cost savings.
Technology and products
- Data acquisition is typically performed by towing a high power EM source over a grid of receivers, 0.5-1 km apart,
- We evaluate the data with our 3D modelling and inversion software, where we can incorporate structural information from seismic interpretations as well as resistivity information the existing well logs.
- We deliver 3D resistivity models and EM attributes in industry standard SEG Y cubes. When seismic interpretations are incorporated, we provide one model, which contains both structural and resistivity information.
The integration of EM data with seismic, well data and other geophysical and geological information is enabled, giving explorationists a clearer, more complete understanding of the subsurface and enabling our customers to draw their own conclusions.
