were safely met and exceeded, resulting in
dogleg severities in the range of 11.0 to
13.99 degrees/100 feet where desired. The
bit had minimal wear after drilling 945 feet
in 23.1 drilling hours for an average penetration rate of 40.9 feet/hour. It was dull
graded 0-1-WT-S-X-I-NO-DTF.
Some of the important performance improvements the operator achieved in Granite
Wash wells by using HBUR RSS in the
curve sections are summarized in Figure 4.
It is evident that the rotary steerable system
drills with significantly higher ROP than
motors, and with one exception, finished
these sections in single runs, achieving
considerable improvements in this challenging environment.
RSS also have been used successfully
to drill the lateral reservoir sections in the
Granite Wash. In this part of the well bore,
incorporating an additional mud motor in
the BHA proved essential to further increasing penetration rates while optimizing
drilling dynamics. Combining a high-dogleg
severity RSS with a mud motor provides
the ability to drill curve and lateral sections
with a single system without a BHA trip.
At present, drill bit life is the driving factor
for additional round trips and it is expected
that further system optimization will provide
additional bit durability and minimize nondrilling time.
Decisive Advantages
While the drilling time savings are important, using HBUR RSS technology also
leads to improvements in other aspects of
the well bore delivery process. Its ability to
drill wells more precisely on plan and to
make flexible, smooth adjustments to the
steering target while drilling ahead provide
decisive advantages in placing the well
bore exactly in the right spot of the reservoir

for improved hydrocarbon exposure. Precise
well bore placement combined with realtime geosteering capabilities also serves to
optimize fracturing operations in shale applications.
Figure 5 shows planned versus actual
well paths from another Granite Wash deployment, where the HBUR RSS were used
in the curve and motor-assisted RSS in the
lateral. The well required a buildup rate to
45 degrees inclination, followed by a combined build and turn to land the well in the
reservoir while avoiding existing well bores.
The system's real-time, near-bit inclination
and rotating azimuth measurements, as well
as automated "on-the-fly" downlink capabilities combine critical features to facilitate
effective steering of more complex well
profiles. Tight steering control is especially
important in applications with close well
bore proximity (e.g., pad drilling or multilateral applications). The ability to perform
an oriented kickoff from vertical provides
another valuable improvement.
The target well was drilled precisely to
plan with minimum deviations. To further
illustrate the benefits of the HBUR RSS,
Figures 6A and 6B provide a comparison
of local DLS in this well with a similar
profile drilled with a steerable motor. The
alternating pattern of high DLS and virtually
straight intervals in Figure 6B reflect the
typical alternating sliding-rotating operation
of steerable motors to drill an intermediate
curvature or tangent section. The resulting
effect is significant tortuosity of the well
bore, leading to higher friction, dissipating
energy that is not available for rock-cutting
action, and driving the necessity of frequent
reaming periods.
In a hard and abrasive environment such
as the Granite Wash, tortuosity and high
well bore friction in the curve also can
drive accelerated wear and tear of the BHA
components and of the drill string throughout
drilling operations. The tortuous profile can
complicate the casing process and lead to
additional challenges during completion
and stimulation. Figure 6A shows the results
achieved with the HBUR RSS, where not
only undesirable high local doglegs could
be avoided, but also the smooth and continuous adjustments of steering while following
the 3-D well profile become obvious.
Increased Efficiency
HBUR RSS with dedicated PDC bits
delivered consistent build rates in Granite
Wash curve sections that are extremely difficult to drill with motors and PDC bits,
and achieved high-quality and smooth well
bores exactly on plan. Significant improvements in ROP and well bore quality have
been documented in the case studies and
the system has proven its potential to
increase the efficiency of directional drilling
operations in this hard, abrasive and complex
formation.
The technology has successfully maintained well trajectories according to the
well plans, using downhole closed-loop
control and automatic tool face control,
consistently drilled the curve intervals with
PDC bits and achieved the required build
