... ). The hardening parameter β becomes: Abstract Compaction Drive consists in the expulsion of oil due to the reduction of pore volume. Generally, unconsolidated sands display an elasto-plastic behaviour during depletion. The limit between the elastic and the plastic behaviour is called the pre-consolidation...

... −6 psi −1 . Recovery factors up to 30% can be achieved if this is an important drive mechanism, making it less attractive to use waterflood. A key point that needs to be assessed in compaction-drive reservoirs is how the recovery attributable to compaction drive might compare to that achievable...

... and subsidence can affect the productivity of the reservoir by increasing the reservoir pressure (i.e., the so-called compaction drive). Intuitively, analyses of production and subsidence should be done in a fully-coupled fashion. However, most, if not all, of the analyses done so far on compacting reservoirs...
