Short presentation that reviews mud losses and how these can be avoided with new technology. By strengthening the wellbore with the right amount of Lost Circulation Material (LCM) you can increase your drilling margin (extend the envelope of your margins). The presentation gives a quick overview of the NCS market and its challenges, and most importantly - how to solve it!

3. PRODUCT BEING PROMOTED
Would you like to stop lost circulation during drilling before it occurs?

4. The Case
Lost Circulation (see http://petrowiki.org/Lost_circulation) comprises a
major drilling cost, whereby Wang, et al, report that, globally, 45% of wells
use casing strings to isolate lost circulation and 19% to 20% of wells
encounter lost circulation after applying extra casing strings.
In addition, to the safety issues of lost circulation and associated rig time
spent treating lost circulation, valuable drilling fluids are also lost.
In 2016: the combined losses of fluid in Water Based Mud (WBM), was
between 25%, and Oil Based Mud reached 32-37% of the total amount
used (Norwegian sector). Regardless of the mud window in which drilling
occurs, the consequences of lost circulation are significant.

10. Cost Analysis
Barite, being a scarce commodity has increased over 100% in a 10 year period, the
drilling mud has increased with 40% over the same time period.

12. The LCM Generating Stabilizer

13. How It Works

14. Wellbore
Strengthening
Fractures will open when the
wellbore exceed its maximum limit.
In this case the Formation has
exceeded it’s limit in σ1 direction,
and starts to deform and there next
starts to crack/fail.
The fluid pressure will propagate
this fracture, just like a axe in a log.
The formation
can’t support
the pressure,
and start to
build a micro
fracture.

15. Sealing Micro fracture
By filling the fracture with
proper sized LCM, making
it possible for the mud to
screen out, and build a
filtrate cake.
The fluid piston, is now
removed from propagating
the fracture.
LCM: 250-600 micron Mud cake buildup
after the fracture has
been filled
