TORTUOSITY
What is Tortuosity?
– Tortuosity is a property of a curve
being tortuous (twisted; having
many turns). There have been
several attempts to quantify this
property. Tortuosity is commonly
used to describe diffusion and
fluid flow in porous media, such
as soils and snow.

TORTUOSITY
Does your lateral look like this?
Does it Matter?
What about the Surface and Intermediate?
Why is it important to achieve exceptional steering control?
Is the best smooth wellbore one that is not steered?
Should we steer 100% of the lateral or should we focus steering only when needed.

UNDULATING TORTUOSITY
What is meant by Undulations in a Lateral?
How can you measure it?
Does it affect production?
Does it impact drilling?
Does it affect the cement job and zonal isolation?
Does this affect the quality of Stimulation
How about Production? $$$

What about Tortuosity in Directional Drilling?
Measure of deviation from a
straight line. It is the ratio of the
actual distance traveled
between two points, including
any curves encountered,
divided by the straight line
distance. Tortuosity is used by
drillers to describe wellbore
trajectory.

Where’s the Value?
Typically, it takes 2 failures before installing an
optimal AL system for a well with flow assurance /
DLS / tortuosity issues.
Cost of 2 AL Systems
Cost of 2 rig interventions
Cost of Gyro survey
Lost oil due to downtime
