SHALEDRIL™ F Water-
Based Fluid proves
Successful on Troublesome
Fayetteville Shale
Location: Fayetteville, Arkansas, USA
OPERATOR’S CHALLENGE – e Marrowian shale that
lies above the Fayetteville Shale in Arkansas is highly reactive
and prone to fracturing and delamination. It is typically drilled
with an Invert Emulsion fluid, which reduces the chance of
swelling of this formation. e operator wanted to use a water-
based fluid that would allow them to inhibit the clays in the shale
and also allow them to drill horizontally with similar lubricity of
an oil-based fluid while keeping costs down. One offset was
drilled with a competitor’s water-based fluid, but assistance was
needed to run casing. e casing had to be pumped to the bottom,
delaying the operation. Typically a dispersed water-based system
is used to drill wells on the Fayetteville Shale, but has shown
inconsistent results in this region.
HALLIBURTON’S SOLUTION – Having engineered a
system specifically to address the unique drilling needs of the
Fayetteville shale, the Halliburton Team offered SHALEDRIL™ F
water-based system as a solution. is non-dispersed system
uses BDF-440, a highly inhibitive product developed by
Houston’s technical team, as a primary component of its drilling
fluid. is fluid met the criteria of the operator and was extremely
successful in inhibiting the Morrowian shale. e fluid was
tested on core samples supplied by the operator as well as cutting
samples and proved to stand up well against the water sensitive
shale. e fluid has been used successfully on multiple wells in
the field, having no issues while drilling and running casing.
ECONOMIC VALUE CREATED – e SHALEDRIL F
system performed exceptionally well in all aspects of the drilling
operations compared with the competitions similar product,
permitting minimal site remediation and other ancillary costs.
In addition to the decreased environmental concern from using
a water-based fluid, the system provided great lubricity values
for horizontal drilling. e average sliding ROP was 30-50 /hr
and rotating at 100-250 /hr, some points having even higher
averages, allowing the well to be drilled more economically. Per
barrel costs were reduced as well as costs related to cuttings
processing, and there were no fees from oil-based mud disposal.
