A major benefit from polymer injection is CO...

...History Matching History matching aims to determine some plausible model variables m that minimise the misfit between the observed production history and modelled response ( Chen and Oliver, 2010 ). Mathematically, the misfit D can be expressed by the following relation (1) D ( α...

..., injection strategy, well control scheme, slug size aand WAG ratio. A robust proxy model is required in a successful optimization project or history match process to ensure both computing efficiency and accuracy. Thus, powerful approaches to develop robust proxy have gained a lot of attention recently...

... Abstract The work discussed and presented in this paper focuses on the history matching of reservoirs by integrating 4D seismic data into the inversion process using machine learning techniques. A new integrated scheme for the reconstruction of petrophysical properties with a modified Ensemble...

.... Stresses in the MEM were initialized from wellbore stress estimates and reservoir simulation pore pressures. One way and two way coupled simulations were performed using a compositional hydrodynamic flow model and geomechanical solvers. Coupled simulations were performed on history matched primary...

.... Objective We aim to advance the applicability of Bayesian History Matching (BHM) for reservoir studies by offering: A systematic workflow to structure BHM techniques. The workflow is designed to (a) scale up to high dimensional input and output data, (b) secure flexibility on combining diverse...

... with simulations from history-matched reservoir models. Methods, Procedures, Process Permanent downhole pressure gauges are routinely installed in most new wells. The resulting large datasets are usually underexploited, however, because it is near impossible to extract information with conventional techniques...

... Abstract Integration of time-lapse seismic data into dynamic reservoir model is an efficient process in calibrating reservoir parameters update. The choice of the metric which will measure the misfit between observed data and simulated model has a considerable effect on the history matching...

... flood data by adjusting control parameters such as reservoir rock properties and Corey exponents to incorporate potential changes in wettability. The history-matched model was then used to evaluate the feasibility and mechanisms for CO 2 sequestration. We used the maximum residual phase saturations...

MDCV trains the correlation between bottom-hole pressure (BHP) variations from PDG data records and rates variations from daily production history of a given well and other wells around it. This provides a robust...

... According to Jansen et al. (2009) , closed-loop reservoir management (CLRM) is a combination of model-based optimization and data assimilation (computer-assisted history matching), also referred to as ‘real-time reservoir management’, ‘smart reservoir management’ or ‘closed-loop optimization...
