bination of wellbore cleanouts utilizing
a workover rig and by installing sand
screens and desanders to prevent blockages
and damage to the downhole pumps, "
Fenley explains. " Crescent Pass has also
designed a pump-in treatment to clear
heel section blockages that do not require
a rig or well intervention. "

With fairly well-defined crude oil, wet gas and dry gas hydrocarbon windows linked to
the thermal maturity and depth of the shale, the Eagle Ford gives operators optionality
to focus drilling investments on the parts of the play with the most compelling
economics. The play's flexibility, coupled with its ample pipeline takeaway capacity and
short-haul proximity to nearby premium Gulf Coast markets, also gives it the ability to
quickly respond to improving price margins for all product streams.

of 2021. Its refrac program resulted in a
year-end 2022 exit field production rate
that was 15% higher compared with the
original base production forecast, according
to Tyler Fenley, co-founder and chief
executive officer of Crescent Pass.
" We are executing refracturing techniques
to improve recovery factors, including
experimenting with a variety of
proppant diverter technologies deployed
at specific points in the fracture treatment
to create near- and far-field diversion, "
he says.
The private independent company has
completed eight successful bullhead refracs
on existing wellbores. " The results so far
have surpassed expectations, yielding internal
rates of return greater than 65%, "
Fenley reports.
As a lower-cost alternative to refrac
designs using liners or other mechanical
isolation methods, bullhead refracs pump

verters. The technique has offered an
economic way to improve the eight
wells' incremental and production rates
and overall recovery factors, according
to Fenley.
Crescent Pass also is preparing to conduct
refracs using liners to isolate existing
perforations and stimulate untreated lateral
segments in two wells. " We are planning
to continue our bullhead refrac program
in some wells, and perform two cemented
liner refracs this summer, " he says.
But when initiating production of a
refractured well, Fenley says one of the
most challenging hurdles is mitigating
potential proppant flowback damage
during the initial restart phase. If not
properly managed, sand production can
degrade the integrity of rod pump artificial
lift equipment and restrict wellbore
flow, thereby reducing the well productivity
improvement that a refrac is designed
to achieve.
" We have addressed both inherited
and new sand production through a comLight

has developed an early detection strategy
utilizing real-time pump dynamometer
tracking to identify sanding issues before
they can become significant problems.
" Real-time monitoring and diagnostics
of the rod pump operation allows us to
optimize performance, " Fenley offers.
" Our engineers in Houston and our well
operators in the field have access to
real-time data through their mobile devices
with custom alarming features set
on a well-by-well basis so they can respond
immediately to any anomaly the
data presents. "
Crescent Pass, which is financially
partnered with Talara Capital Management,
is keeping an eye open for bolt-on acreage
acquisition opportunities in the Eagle
Ford, Fenley adds. " Our long-term plan
is to continue growing through accretive
acquisitions where we can focus on operational
excellence and create value for
our shareholders, " he concludes.
Infusion Of Innovation
With a large chunk of assets changing
operator hands in the most recent round
of Eagle Ford dealmaking, the play's
future no doubt will be shaped by the
same forces that have driven activity
during the 15 years since its commercial
discovery: an infusion of innovative
thinking and new technology application
to optimize the productivity of oil and
gas wells in the shadows of Gulf Coast
market centers.
INEOS Energy's entry in the play encompasses
172,000 acres and 2,300 wells
producing 36,000 barrels of oil equivalent
a day. The acquisition is expected to
close in the second quarter, with an effective
date in October 2022.
