SpecialReport: Horizontal & Innovative Drilling
ing the tool's capability for flow-off surveys
by conducting measurements during connections and allowing the directional driller
to get back on bottom quickly. Downlinks
were coordinated between the drilling and
reservoir navigation groups to save time, and
were executed on-the-fly at faster ROPs.
Drilling parameters were managed actively to control both borehole and downhole dynamics. Since torque and drag were
the biggest constraints to delivering longer
laterals, wellbore quality was assessed and
monitored in real time to minimize downhole dysfunctions, improving overall efficiency. Downhole dynamics data monitoring was executed to minimize and manage downhole vibrations that could damage the bit or tool.
Record-Setting Results
Four of the eight Pad 1 wells achieved
footage rates up to one mile a day (wells
1E, 1A, 1B and 1I), and five of the eight
(wells 1DST1, 1E, 1F, 1J and 1I) remained
in the target zone 100 percent of the
time. Compared with the Pad 2 wells, Pad
1 wells recorded a 7 percent increase in
ROP, a 3 percent increase in total footage
drilled, a 2 percent increase in in-zone time,
and a 9 percent increase in the amount of
footage drilled per day.
Figures 6A and 6B group Pad 1 wells by
chronological order and orientation (southeast versus northwest). Wells 1DST1, 1E
and 1F in the southeast direction drilled less
footage as a result of lease constraints, but
a positive trend of increased footage with

in 2012 as a field engineer in the Marcellus, Upper Devonian, and Utica Shale
plays. Gorr holds a B.S. in civil and environmental engineering from Carnegie

100 percent in-zone time is visible. Figure
6A breaks down some of the KPIs for the
curve and lateral sections, while Figure 6B
includes drilling KPIs, such as the mile-aday records side-by-side with the percentage of time in the target zone.
As Pad 1 wells were drilled, best practices were adjusted for each subsequent
well. The final well drilled on Pad 1-well
1I-is demonstrative of the outstanding results the project achieved. The well 1I lateral was drilled updip targeting the Upper
Devonian Rhinestreet formation, drilling
14,753 total feet in one run. It had a 37 percent longer lateral than the average Pad 2
well, but was drilled with 13 percent
higher ROP, recorded drilling rates up to
5,293 feet/day in the lateral, and stayed inzone 100 percent of the time.

The best drilling rate was recorded on
well 1B, which achieved 5,821 feet/day with
93 percent in-zone time while drilling updip in the Marcellus. The longest well drilled
in one run was 1C, with 15,084 total feet.
The multidisciplinary team approach
combined with HBRSS technology and
carefully defined best practices enabled
flawless execution of the high-BUR curve
and long lateral sections in one-run drilling
operations on the Pad 1 wells, and set a
new standard for future pads on the PIT airport project as well as other locations
across the Marcellus play.

Venari Says Well Extends Shenandoah Play In Gulf
DALLAS-Venari Resources LLC says
its Shenandoah No. 5 appraisal well encountered more than 1,000 feet of highquality oil play in the Lower Tertiary
Wilcox sands. It adds the well, in the Gulf
of Mexico's Walker Ridge Block 51, was
drilled in 5,900 feet of water to a total
depth of 31,100 feet.
The company drilled the well up-dip of
the Shenandoah No. 2 appraisal well, and
was designed to confirm and extend reservoir boundaries. Venari says its next appraisal well, Shenandoah No. 6, is expected to spud later in 2016. Earlier this

year, the company says it increased its
working interest in the Shenandoah Unit
to 17 percent from 10 percent.
"With a high-quality reservoir and
substantial net oil pay, the well results confirm Shenandoah to be a significant oil accumulation," assesses Brian Reinsborough, president and chief executive officer of Venari.
The other Shenandoah co-owners are
Anadarko Petroleum Corp., as operator (33
percent); ConocoPhillips Co. (30 percent); and Cobalt International Energy LP
(20 percent).
