Compressibility Effects in Modeling Two-Phase Liquid Dominated Geothermal Reservoirs
Abstract/Contents
- Abstract
- The use of the Hurst Simplified Model to history match the drawdown behavior of liquid dominated geothermal reservoirs is studied. Liquid dominated reservoirs virtually always have a region of intimately mixed vapor and liquid (two-phase zone). Such regions have high compressibilities up to three orders of magnitude greater than that of liquid only. It is therefore important that a reservoir model remains valid over a large range of compressibilities, and that it not require reservoir compressibility as an input parameter. The Hurst Simplified Model, linear and radial geometries, is formulated for use in liquid dominated geothermal reservoirs. The model is tested on drawdown histories of five reservoirs (Ahuachapan, Broadlands, Ellidaar, Svartsengi, and Wairakei) spanning a large range of compressibilities. The matches yielded reasonable compressibilities and fits to histories in most cases, with the fields at either compressibility extreme introducing only slight problems.
