:: HORIZONTAL DIRECTIONAL DRILLING
A&L entered the directional drilling market in
1985 when we built one of the industry's first “mini-rigs”, a pit-launched,
but steerable, drilling rig to perform rock drills for the
telecommunications industry. Since that time we have grown to be an industry
leader in directional drilling, capable of handling an entire project, from
initial site investigation through drilling and as-builts. We have
extensive international drill experience in North and South America.
Much of our international drilling work is done in
cooperation or joint venture with local national contractors and we are
always looking for such opportunities. Privet and governmental
participants are welcome to contact us about specific opportunities in the
directional drilling or pipeline markets.
A&L's “pipe-side” capability includes experience with all utility types and
sizes, including polyethylene and steel. By including our pipeline or
gas distribution divisions we can provide customers with a turnkey contract
solution on almost any HDD project whether in the US or international in
scope.

With
trench-less technology, environmentally sensitive areas can be addressed
with minimal disruption and at tremendous cost savings. A & L owns
and operates directional drilling rigs from the very large to the small
mini-rig class, all of which are available to the environmental
community.
Horizontal wells also provide an effective
method for removal of methane gas and enhancing leach-ate collection
systems without sacrificing the integrity of the landfill or other
containment systems.

SIGNIFICANT PROJECTS
Horizontal Potable
Water Well – Des Moines, Iowa .
The
city of Des Moines' infiltration gallery water system was antiquated and
insufficient to handle the expanding population. The city found an abundant
water supply in a shallow aquifer located beneath the Racoon River valley.
Because of the nature of the aquifer and the city's desire to control
draw-down, they chose to install a horizontal well rather than the more
traditional vertical wells.
The city selected A&L Underground to install the well. A&L was
selected because of their reputation, their expertise in HDD and their
track record. A pilot test was initiated to design and install one well. If
it performed at its designed flow of 2,200 gpm, seven other wells would be
installed. A&L did the 1,820 foot horizontal directional bore and
installed 1,229 feet of 12-inch well screen with 300 feet of 18-inch steel
lead pipe and 300 feet of 12-inch steel tail pipe.

SIGNIFICANT PROJECTS
Chevron Pipeline -
Salt Lake City, Utah
Dual pipelines had originally been installed along a residential street
through the City of West Bountiful and a city road project was not going to
require their relocation. After examining options to reroute, the
pipelines' existing location appeared most economical despite stringent
city requirements for their installation.
A&L Underground installed 8,000 linear feet of dual eight inch product
lines with a directionally drilled hole, making this transmission pipeline
rerouting one of A&L's longer single horizontal directionally drilled
projects. Chevron had specified drilling on the job due to a number of
local concerns.
The City imposed time restraints, noise and environmental controls, as well
as depth requirements throughout the residential area. Extremely rigid time
constraints imposed by Chevron's pumping schedule also posed concerns. The
lines were installed in less than four weeks, far ahead of schedule.
Quicker drilling completion was attributed to the use of surface survey
techniques.
