SPE 109975 Estimation of Initial Fluid Contacts by Assimilation of Production Data With EnKF
Much recent work on automatic history matching and data assimilation has focused on the adjustment of simulator gridblock permeabilities and porosities. Here, we show that when production data are assimilated into reservoir models with the ensemble Kalman filter, it is relatively easy to account for uncertainty in the depths of the initial fluid contacts and provide estimates of these depths in...

متن کاملP1.44 The Issue of Data Density and Frequency with EnKF Radar Data Assimilation in a Compressible Nonhydrostatic NWP Model
1. Introduction Since its first introduction by Evensen (1994), the ensemble Kalman filter (EnKF) technique for data assimilation has received much attention. Rather than solving the equation for the time evolution of the probability density function of model state, the EnKF methods apply the Monte Carlo method to estimate the forecast error statistics. A large ensemble of model states are inte...
متن کاملThe Development of a Hybrid Enkf-3dvar Algorithm for Storm-scale Data Assimilation
Many studies have been performed during the past decade aiming to use Doppler radar data for initializing cloud-resolving models. At the Center for Analysis and Prediction of Storms (CAPS), the ARPS Data Analysis System (ADAS, Brewster 2003a, b), with incremental analysis updating capabilities, was developed as the first step towards assimilating radar data and other conventional and remotely-s...
متن کاملParticle filter and EnKF as data assimilation methods for the Kuramoto-Sivashinsky Equation
The Kuramoto-Sivashinsky equation plays an important role as a low-dimensional prototype for complicated fluid dynamics systems having been studied due to its chaotic pattern forming behavior. Up to now, efforts to carry out data assimilation with this 1-d model were quasi totally restricted to variational adjoint methods domain and only Chorin and Krause [26] tested it using a sequential Bayes...
