After 8 months of production (last available data point)
After 10-years of production (forecast)
Because of the very low mobility, even after 10
years we have hardly reached any further from
the well itself. This is in consistency with the
theory of “SRV” stimulated reservoir volume:
even if the well is drilled in a large reservoir
area, it will only produce from a much more
restricted volume (the SRV) during its
operational life, because it would take an
unrealistic time period to reach the actual
reservoir boundaries.
However this may not always be the case
depending on the reservoir permeability and is
not strictly restricted to the area defined by
the fractures, thus a nonlinear numerical
MFHW simulation is necessary to observe the
drainage pattern.
