Development and Verification of Simplified Prediction Models for Enhanced Oil Recovery Application: Steam Flood Predictive Model

摘要

To facilitate the screening and evaluation of reservoirs for the application of steam drive as an enhanced oil recovery process, a simplified predictive model for steam drive performance has been constructed. This model is an extension of existing analytical heat balance models to include fractional flaw characteristics, vertical and areal sweep effects, steam injectivity, and heat losses in wellbores and surface pipes. An economic analysis package is included in the model to allow for estimation of key costs and benefits of potential steam drive projects, and to calculate project profitability. An extensive set of defaults are included to allow execution of the model when only minimal data are available. The Steam Flood Predictive Model (SFPM) is described and demonstrated in this report. 43 references, 22 figures, 9 tables. (ERA citation 10:006360)
