GAS PRODUCTION MORE THAN 55%

46% Propel SSP Tail-In
vs. Slickwater Frac
ESCONDIDO FORMATION, RICH GAS PLAY
INTRODUCTION
An operator working in the Escondido formation in Webb County, Texas, recorded
a 60-day initial production increase of more than 55% using Propel SSP compared
with the slickwater offset well. The operator also eliminated fluid sweeps,
decreased fluid additives, and reduced pumping time, all of which enhanced
production success. These results were achieved in a low-permeability sandstone
well with Propel SSP tail-in as 46% of the total proppant volume.
Propel SSP technology was coated on 30/50 Northern White sand compared with
uncoated 20/40 Northern White sand used in the offset well. The operator also
used 100-mesh and 40/70 Northern White sand in both wells. The smaller-mesh,
lower-conductivity frac sand coated with Propel SSP outperformed the
larger-mesh, higher-conductivity frac sand, based on the production results,
by maximizing the fracture surface area.

WHAT IS PROPEL SSP
PROPPANT TRANSPORT
TECHNOLOGY?
The self-suspending proppant
technology, which resists settling
in a low-viscosity fluid, uniformly
distributes proppant throughout
the full length of a created
hydraulic fracture. Ultimately,
this better transport increases
stimulated reservoir volume
to reduce cost per BOE.
The technology requires less
pumping time because of
the higher capacity to carry
proppant compared with
slickwater. An operator can
eliminate fluid sweeps because
of the hydrogel-coated
proppant’s lower effective
specific gravity, in addition
to using less fluid additives
because less fluid volume
is needed.
THE RESULTS
After 60 days, cumulative gas production increased more than 55%. Gas production for the
offset well was 85,207 Mcf compared with 132,678 Mcf for the Propel SSP technology well
even with the lower-conductivity sand.

Besides this greater production value with Propel SSP technology, the operator reduced
stage pumping time by 25%. The operator used 15% less fluid additives, including friction
reducer, biocide, clay stabilizer, and surfactant. With the eliminated fluid sweeps and higher
sand concentration, water consumption decreased 10%.
