Project Planning
Modern drilling bits are remarkably
sophisticated pieces of machinery, containing their own motors, computerized steering
tools and even sensors that can detect what material lies ahead. Computer operators above
control which direction they drill in, and by analyzing the feedback from the drilling
assembly, pinpoint exactly where they need to go.
In the next millennium, the industry will face
problems and challenges associated with the wellbore and the near-wellbore region.
Drilling Services, Inc. continues to provide value to our customers by focusing on the
enhancement of "smart drilling," such as:
 | "smaller footprint" drilling technologies, |
| "smaller-rig" drilling, |
| "smart-drilling" well technology, |
Drilling Faster... The need for increased efficiency during the drilling phase of
energy production. Recognizing that drilling rig time is the most expensive part of
operation (30 to 35 percent), the objective then becomes to increase the efficiency with
which the well is drilled. This can involve reductions in equipment failure, extension of
drill bit life, and reaching the target zone with the fewest number of course corrections
possible.
Drilling Deeper...The varied and complex geologic environments that exist and affect
the drilling phase. Drilling into these environments requires unique drilling strategies
that use the specific characteristics of the geologic formation itself to assist in
generating a hole. An example of this is the deeper, harder rock formations that contain
natural gas. For those formations, the most efficient strategy is to focus on the brittle
nature of the rock itself. When hit or hammered, this rock will break into large chips.
This is a more effective drilling strategy than to crush and grind the rock into powder,
as would be done using conventional roller cone bits. Other formations are sensitive to
the type of drilling fluid used. In these cases, the best strategy is to use air as the
drilling medium.
Drilling Cheaper...There is still no substitute for drilling. The goal, therefore,
is to develop technology that will allow the most "cost-effective" drilling.
Costs are measured in terms of the least impact on the environment, the longevity of the
wellbore and all its components, and the long-term productivity of the wellbore. This
means drilling a well with mechanical longevity that does not inhibit the entry of fluids
from the reservoir, and that is placed at the precise location needed to achieve the
ultimate recovery of oil and gas from a particular type of reservoir.
Drilling Cleaner... Minimizing the environmental impact of drilling activities. This
can range from reducing the amount of surface disturbance that results from the drilling
phase of energy production, to dealing with the final disposition of used drilling fluids,
drill cuttings, and other waste generated by drilling activities. The use of small bore
"slimhole" wells has led to a 75 percent reduction in the amount of surface
disturbed and the amount of waste generated. Operating costs are also reduced by up to 50
percent.
Drilling for the
21st Century... Finally, there is a need for drilling
systems that anticipate problems and apply the self-correcting adjustments needed to
precisely place the wellbore.
Drilling Services, Inc. works consistently to improve and expand our services to meet our
customers' changing needs. We work with our clients to provide drilling techniques that
meet their specifications. We provide innovative and dependable solutions to difficult or
unusual drilling conditions.
