TECHNOLOGY BRIEF
Phillip Morgan
CWT Global Operations Manager
What is it?
CleanWell® system technology is
an engineered solution meeting
the well cleaning objectives to
sustain tough drilling parameters.
▌ 26 tools in the product line
▌ Cleans casing ID
▌ Mechanically removes debris
from the wellbore
▌ Provides hydraulic boosting to
increase fluid velocities
▌ Helps reduce mechanical risk
and promote rig time savings
▌ Primary applications include but
not limited to:
 Drilling
 Cleanouts and displacements
 Post perforation runs

How it will Benefit you
▌ Robust, casing-friendly drilling systems engineered to promote downhole
cleaning and debris management.
 Wellbore cleanout solutions help minimize drilling and completion
costs by saving time and trips.
 Tangible savings are typically identified in the planning stages,
intangible savings are realized when it comes to unplanned events or
unexpected debris.
▌ CleanWell® system technology exceeds the weight-down limitations of the
bottom bit or mill, and tensile and torsional values exceed the workstring
connection.
 Required tools can be placed appropriately in the well to help ensure
performance
▌ Consistent debris removal
 Large debris capacity for removal
 Debris extraction tools not a limit for drilling environment

Why it will Help
▌ Unplanned downhole benefits
 Debris inadvertently dropped down hole consistently recovered
− Mag Tech® magnets capturing magnetized components
− Non-ferrous recovery with Vali Tech® filter screen tools alleviating
fishing operations
▌ Planned benefits (combining runs saving money)
 Single Trip Drillouts
− Performing drillout run to establish bottom with displacement tools
deployed
 Saves dedicated drill out run
 Negative Test
− Utilizing the rotational Inflow Tech® negative test packer with
cleanout and displacement run
 Saves dedicated negative test run
 Incorporate polish mills for VersaFlex® liner hangers saving
another dedicated run

Where it Will Work
▌ CleanWell® system technology utilized in all phases of the well
construction
▌ Primary applications include:
 Drilling
− Plug and Abandonment cleaning runs
− Window mill cutting runs
− Tools to ensure drift for casing being run
 Cleanouts and Displacements
− Establish bottom and displace mud to brine in one run
 Fishing Applications
− Debris removal utilizing debris extraction tools and mills
 Post Perforation Runs
− Packer plug retrieval runs utilizing CleanWell® products including
Vac Tech® eductor system

Challenges Addressed
▌ Downsizing debris and debris removal
 Critical link between drilling and completions operations
 Sets the stage for completion success
− Important step for Halliburton / client completion assurance
▌ Best opportunity to get ahead of the debris curve if designed properly
 Provides debris downsizing and removal throughout the well
 Constantly addressing debris beginning in drilling stages provides
for manageable operations throughout
