Assisted history matching in the presence of frequent well intervention using generalize travel time inversion

Assisted history matching in the presence of frequent well intervention using generalize travel time inversion

Journal of Petroleum Science and Engineering 78(2): 415-430

In this paper we propose an efficient and novel technique that handles production discontinuities through a resampling of the production data, eliminating high frequency production details in a transformed domain. The technique also reduces non-monotonic behavior and results in a response more suitable for the GI based misfit calculations. Our proposed approach has been applied to an offshore turbidite reservoir with extensive well intervention resulting in highly detailed production responses. The static model contains more than three-hundred-thousand cells, complex sand depositional distribution combined with fault structures, four pairs of injector-producers, deviated producing wells and more than 8years of production history. Research highlights: Method for production data integration using the generalized travel time inversion in the presence of active reservoir management and highly detailed schedules. The proposed approach robustly calculates the best time shift and does not exhibit a sensible behavior with respect to the selected threshold criteria. Comparison of the proposed resampling of the production data with the traditional equal time interval filtering is presented showing a greatly improved performance with a very simple implementation. The applicability of the proposed approach is demonstrated using a real field application with active production management characterized by many shut-in's and several recompletions at different sands. The final calibrated model is used as a diagnostic tool in order to identify places with potential interpretation problems either in terms of reservoir quality (net to gross) or sand thickness.
