IOR (Improved Oil Recovery)
IOR = Improved Oil Recovery.
IOR refers to any practice to increase oil recovery. That can include EOR processes, as well as practices to increase sweep such as infill drilling, horizontal wells, and polymers for mobility control or improved conformance. In practice, such items as reservoir characterization or simulation (which are nearly always part and parcel of any recovery concept) are included in planning, execution, and analyzing the technical and economic results. Arguably, such defacto supporting activities should also be recognized within the definitions. But this approach muddies the definitions considerably, and we recommend they not be included.
