...’ uncertainties and improves historical fitting accuracy by increasing ensemble numbers. The Ensemble Kalman Filter (EnKF) algorithm, proposed by Evensen, is widely used in reservoir history matching for its computational efficiency and ease of implementation ( Evensen, 2003 ). Following EnKF's sequential data...

... probability distributions used to sample representative models for planning purposes. Probabilistic maps of connectivity were generated using streamline simulation to guide both history-matching and well-placement activities. Decision criteria were developed that integrated model-based technical and economic...

... For L-Field case, we are focusing to formation damage during well intervention and during production phase. Damage is often created during workover operations. Workover history must be investigated thoroughly to uncover one or more possible damage contributors, including the following: Use...

... acquisition. The technique delivers formation pressure history and productivity index history in tested well reconstruction. It is also proficient to reconstruct cross-well interference and estimate cross-well transmissibility from offset wells towards the tested well. Another result is evaluation...

... and forecasting tool for unconventional oil and gas assets is a challenging task. This is mainly due to the high number of wells involved and the limited predictability of detailed individual well performance until there is sufficient production history. Current methods to optimize and forecast production rely...

... Abstract This paper presents an automated method to speed-up the process of history-matching simulation models. A new tool "History Match Process Optimizer– HMPO" was developed to allow local modification of simulation model property arrays around any given well type. Deployment of this tool...

However, owing to the poor quality of oil production...

.... To achieve full field history matching, the final geological model was upscaled to serve as input data in dynamic history matching. An excellent and nearly perfect history matching with a least mismatch was obtained between the measurement and simulated bottom hole pressure from well test and production...

To support this strategy, an integrated optimization study with reservoir simulation model was used instead of analytical method to obtain more reliable production forecast. History matching was carried out...
