Comparative analysis of binary and conventional seismic assisted history matching

A comparative analysis of seismic assisted history matching techniques using binary image matching and conventional seismic modelling methods is performed. This analysis is conducted on field data from a United Kingdom Continental Shelf (UKCS), and has production data available for ten years. There is a seismic baseline that was acquired preproduction, and six seismic monitor surveys were acquired between one and two year intervals. The production data objective function is calculated using the least squares method between the historical production data and simulation predictions. The seismic data objective function is calculated using the Current measurement metric in the binary approach, and compared to the conventional seismic modelling route. Seismic modelling shows some improvement in the match, but not as significant as the binary approach which demonstrates a better forecasting capability. The study also found that a greater proportion of the parameters converge towards the correct solution when using the binary approach. It is observed that for both methods, combining both production and seismic data improves the history match and reduces uncertainties, as opposed to not combining them.
