Integrating forward modeling into reservoir simulation

Using time-lapse seismic monitoring to identify trapping mechanisms during CO2 sequestration

“…The porosity is calculated using a porosity-depth relationship derived from normally pressurised North Sea sandstones (Sclater and Christie, 1980) and is assumed to be constant throughout the sand interval. Whilst the horizontal permeability is determined from the porosity using the Tixier equation (Schlumberger, 1991), the vertical permeability is assumed to be one tenth of this value; a ratio which has been used in other simulation studies (Fanchi, 2001). Relative permeability and capillary pressure curves for CO 2 and brine (Fig.…”

Geophysical evaluation methods for buried hill reservoirs in the Jiyang superdepression of the Bohai Bay basin, eastern China

“…Seismic forward simulation serves as a bridge between geological model and seismogram (John 2001, Anatoly et al 1999 and provides us with an effective method to completely investigate the distribution of features in a reservoir. Based on the rock petrophysical parameters, we build an accurate geological model and then compute the seismogram by forward simulation, thereby defining the seismic characteristics of the reservoir.…”

Experimental Evaluation of the Petrophysical Algorithm in an Integrated Flow Model

“…One advantage of including the petrophysical algorithm in a flow model is to facilitate the calculation of seismic attributes for integrating time-lapse (four dimensional [4D]) seismic observations in reservoir flow modeling (Fanchi, 2001). The emergence of 4D seismic monitoring increases the benefits of IFM over traditional flow simulation and expands the use of seismic analysis from identification of hydrocarbon structures to include estimation of fluid types and flow patterns (Wang, 1997;Fanchi and Batzle, 2000).…”
