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
