Evolution of Dual Pipe
to the swivel, for more downhole
flow capabilities."
Using 15-foot-length drill pipe,
AT40 can carry 360 feet of drill pipe
for reduced cycle times. The machine
includes a patent-pending reversible
pipe box for added job-site versatility.
Maker added that the advanced
AT system also has an enhanced
RockMaster housing for reduced
maintenance and improved longevity. A modular design makes the
housing adaptable to two different
sizes of drill bit using regular API
connection.
The housing has an industry-exclusive, double-layer seal with
high-capacity bearings, as well, for
increased downhole life. This doubles
service -time intervals when compared to previous models.
The current AT lineup ranges
from 30,000 to 100,000 pounds of
pullback.
Deploying Fiber Through Rock
The value of mechanical dual-pipe HDD
technology is demonstrated on the job.
Ditch Witch Product
Manager Cory Maker
describes how a JT30
all-terrain model
(forerunner of the
AT30) was used on a
fiber deployment job
by Oregon contractor
West Pacific Drilling.
"Conditions underground were extreme, with nearly 80 percent of the project being hard rock," he
said. "Fractured rock also was scattered throughout the job site.
"On this portion of the backbone work, a Ditch Witch JT30 was used. Dual-pipe, all-terrain
technology helped to productively make installations through the tough ground and decrease the
amount of fluid often needed for rock drilling. Less fluid volume helped reduce environmental
impact, fluid waste and site cleanup, which helped us complete the work in a tight timeframe."
