Simultaneous Joint Inversion

As exploration for hydrocarbon resources moves to increasingly complex geological environments, the integration of multiple physical measurements is needed to build improved earth models. Nonseismic methods are helping reduce exploration risks and improve development decisions by providing additional information for building a more accurate earth model.

Integrate datasets

The simultaneous joint inversion (SJI) of multiple geophysical datasets (e.g., seismic and gravity, and seismic and magnetotellurics) is a new technology that allows integration of different geophysical datasets at the inversion level. SJI collects seismic and nonseismic information into a single-objective function to be inverted.

Advantages of the SJI approach include

• reduced uncertainty in the interpretation result through integrating independent geophysical measurements into a consistent earth-property model
• mitigated weaknesses of each single domain dataset through the strengths of the other dataset(s).
