SpecialReport: Wellbore Construction
well, and another study concluded that
a Middle Bakken well could produce a
fracture network that could adequately
drain an unstimulated Three Forks lateral
450 feet away. One may infer that sacrificial
child well fracs can intersect an
understimulated parent well and drain
the same reserves that a parent well refrac
can recover. Nearly half of the
sacrificial fracs in this study resulted
in significant production response in
parent wells.
Most operators face similar depletion
challenges respective of the completion
time difference between parent and child
wells. Although development decisions
remain largely driven by surface constraints,
there are some commonalities
among operators in this study.
Operators have acknowledged parentchild
well FDIs, as evidenced by wider
spacing of child wells in proximity to
parent wells and an increase in parentchild
spacing over time. Operators also
appear to be stimulating nearest the parent
well first where facility or scheduling
constraints do not limit choice.

DARREN SCHMIDT is the assistant
director for energy, oil and gas at the
Energy & Environmental Research
Center at the University of North Dakota.
He leads a team focused on research,
development and commercialization
related to efficient and clean fossil
fuel production, carbon management
and renewable energy. Prior to joining
EERC, Schmidt worked in operations
and research for Equinor in the Williston
Basin. He holds a B.S. in mechanical
engineering.
KYOUNG SUK MIN is a reservoir engineer
at EERC, focused on solving
advanced challenges in conventional
and unconventional reservoirs such
as production mechanisms and enhanced
oil recovery in tight reservoir
rocks, CO2- or produced-gas-based
storage, and production data analysis
and interpretation for unconventional
reservoirs. Before joining EERC, he
served as a senior reservoir engineer
at Anadarko Petroleum, Pioneer Natural
Resources and Eden Geotech.
Min holds an M.S. in mechanical engineering
from the University of Michigan
and a Ph.D. in petroleum engineering
from Texas A&M University.
STEPHEN GUILLOT is a distinguished
reservoir engineer in the subsurface
initiatives group at EERC, where he
interfaces with a diverse team of scientists
and engineers to assess project
uncertainties in oil and gas development
and geologic CO2 storage. Prior to
joining EERC, Guillot was an independent
consultant and a reservoir engineering
advisor for Denbury Resources.
He holds an M.S. in petroleum
engineering from the University of Texas
at Austin and a B.S. in civil engineering
from the University of New Orleans.
