Issues related to the influence of reservoir properties uncertainty on oil field development modelling are considered. To increase reliability geological-hydrodynamic mathematical model in course multivariate matching, design technological parameters was estimated, and their mutual determined. The optimal conditions for deposit were determined, forecasts made. described approach history matchin...

EAGE Workshop: Integrating Reservoir Engineering with Geology and Geophysics, 26 May 2002 Summary This paper will describe a technique for generating an ensemble of history matching models using the Neighbourhood Approximation algorithm. Using the ensemble of models generated, we demonstrate how uncertainty in reservoir performance prediction can be quantified by sampling from the posterior dis...

The most common data that engineers can count on, especially in mature fields, is production rate data. Practical methods for production data analysis (PDA) have come a long way since their introduction several decades ago and fall into two categories: decline curve analysis (DCA) and type curve matching (TCM). DCA is independent of any reservoir characteristics, and TCM is a subjective procedu...

Streamlines have proven useful for visualizing and solving complex history-matching problems that enhance reservoir description. This paper presents a novel, multiple-scale streamline-based technique that perturbs the reservoir model in a manner fully consistent with prior geological data. Streamlines define dynamic drainage zones around production wells and the mismatch between historical and ...

Handling flow through fractured media is critical for transient pressure and flow analysis in shale gas reservoirs, because gas production from such low-permeability formations relies on fractures, from hydraulic fractures and fracture network to various-scaled natural fractures, to provide flow channels for gas flow into producing wells. This study presents a numerical investigation of pressur...

introduction: in this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. a window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. material and methods: the program was...
