| description | To provide techniques that include methods for determining an amount of hydrocarbon recoverable from porous reservoir rock by miscible gas flood, apparatus, and computer program products.SOLUTION: The techniques include the steps of: retrieving a representation of a physical porous reservoir rock sample (porous reservoir rock), where the representation includes pore space and grain space data corresponding to the porous reservoir rock; locating the position of substantially immovable oil blobs or patches in the retrieved representation of the porous reservoir rock; and evaluating the changes in mobility of blobs for two or more iterations at work levels of a given EOR technique to estimate a variation amount of blob mobilization between first and second iterations of the given EOR technique, where the first iteration among two or more iterations expends a first work level and the second iteration among two or more iterations expends a second, higher work level.SELECTED DRAWING: Figure 1
【課題】混和性ガス攻法によって多孔質貯留岩から回収可能な炭化水素の量を決定するための方法、装置、およびコンピュータプログラム製品を含む技法を提供する。【解決手段】物理的多孔質貯留岩サンプル（多孔質貯留岩）の表現を検索するステップであって、表現が多孔質貯留岩に対応する孔隙空間および粒子空間のデータを含むステップと、多孔質貯留岩の検索された表現において実質的に不動の油の塊またはパッチの位置を特定するステップと、所与のＥＯＲ技法の作業レベルでの２回以上の反復にわたって塊の易動度の変化を評価して、所与のＥＯＲ技法の第１の反復と第２の反復との間の塊の可動化の変化量を推定するステップであって、２回以上の反復のうちの第１の反復が、第１の作業レベルを費やし、２回以上の反復のうちの第２の反復が、第２のより高い作業レベルを費やす、ステップとを含む。【選択図】図１ |
