3D Wellbore Rendering

• Geology & Reservoir Modeling

• Drilling Target & Anti-collision

• Production Engineering

How can we bring high quality,

interactive wellbore modeling

to production engineers?

Or even field personnel?

Mobile Apps vs. Desktop vs. Webpages

• Everyone knows how to view web pages

• Can target numerous platforms/devices

• Webpages can look more or less the

same across different devices

But we can’t do advanced 3D

graphics in webpages…

The Modern Web Browser

• Increasingly standards based

• Increased performance

• Both desktop & mobile

• Native 3D support

– No plugins, just the browser

Just Technical Semantics What use is all of this?

Why is it so difficult to see a high

resolution, interactive wellbore?

Analogy:

Maps

The problem with statically rendering wellbores

• Long & Slender

– Lose detail

– Lose frame of reference

• Unequal dimensional scaling

– Straight wells appear deviated

• Squished

• Distorted

How to make a straight well look crooked straight

But we can

zoom in!

• Equal dimensions (X=Y=Z)

• Not nearly as bad as

it looked before

• But we can’t really see

any of the details…

High Resolution Survey Data


Denver, Colorado

11

Dog-Leg Severity (DLS)

• Easily see the high DLS sections

on the wellbore

• Color coded

– Red = High DLS

• Perspective on what

the DLS regions

actually look like

• Color coded

– Red = High DLS

• Perspective on what

13

Rod-on-Tubing Wear

• Color coded overlay (Similar to DLS coloring)

• Conventional wear color bands are not ideal

– Correct to green-red

• Still no inherent notion of

“As Run” vs. “As Pulled”

• Can be added to determine

the rod wear incurred from

the current run

Collaboration

• How to ensure everyone is looking

at the same view?

• Synchronous – Screen Sharing

– Complex, High Bandwidth, not suitable

for spotty connections. Software/support

• Asynchronous – Email

– Convenient, but not interactive

– Simple & Ubiquitous

• Distributed view state synchronization

– Live/real-time or snapshot-able

Device Support

• Can I use advanced 3D graphics – Does my

browser/device support WebGL? – Desktop – IE 11, Chrome, Firefox

– Mobile – iOS 8+, Android (Mixed, but generally Chrome works or can be enabled)

• If your PC is at least 5 years old, or if your mobile device

is at least 2-3 years old, there’s a good possibility it’ll work

– May need the latest OS/browser updates

– Anything currently on the market should work

• Otherwise, fallbacks to slower rendering engine

– Still usable, but not as responsive

Conclusion

• Useful & convenient – Easy to access

– Laptops & Most cellphones

• Better analyze downhole equipment

– Placement and performance

• Not quite a commercial product yet (perpetual beta)

– Feedback would be appreciated

– http://deviationsurvey.com/demo

• Drawbacks – Subject to survey data accuracies

– Potentially misleading if inputted data is wrong

– Corporate firewall issues (accessibility)
