WellFracturing: Diagnostics
because of the depletion of the lower parent
well, so those fractures were more likely
to grow into a single dominant fracture
per stage, resulting in larger geometries.
The pressure-based fracture maps also
were used to investigate how volume
pumped influenced fracture growth. In
most of the toe stages, dominant fractures
grew more linearly through the end of
the stages, as illustrated in Figure 3.
For the heel stages of BC1H and
BC3H, the rollover of the growth curves
occurred when ±3,000 barrels of fluid
were pumped. The dominant fracture
slowed or stopped growing after pumping
3,000 barrels, and fracture complexity

continued developing through the rest of
these stages as the remaining fluid was
injected. The black line in each graph
represents the average growth curve for
the stage group. The regions of darker
red shading in the plots indicate where a
higher density of individual growth curves
fall within each group.
The growth curves of the heel and toe
stages of the BC2H did not roll over.
Lower pump rates yield a lower net pressure, and with reduced net pressure, a
smaller stress intensity occurs at the fracture tip. With less stress intensity at the
fracture tip, a smaller ultimate fracture
half-length is likely. In the heel stages,

which are closer to the parent well depletion, this difference in geometry is
likely related to the lower stress field of
the depleted area around BP2H.

Editor's Note: The preceding article
is the second in a two-part feature on
pressure-based fracture mapping. Part I
appeared in AOGR's August issue. For
more information on the technology or
case studies referenced, see SPE 199705,
which was originally prepared for presentation at the Society of Petroleum Engineers' 2020 Hydraulic Fracturing Technology Conference & Exhibition, held
Feb. 4-6 in in The Woodlands, Tx.
