... these advantages, the black -oil equations are used often to model many EOR processes, including those where the black -oil assumptions may not strictly apply. Black -oil equations, for example, ... oil rate is declining as from A to B. At B, an EOR project is initiated and, if successful, the rate should show a deviation from the projected decline at some time after B. Incremental oil ... 1-3. Figure 1-3.
