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 3

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 ® fishing operations filter screen tools alleviating ▌ 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 4

Unique Features

▌ ▌ ▌ ▌

Primary drillable tools designed for placement directly above the bit allowing single trip drillouts

  Tensile and torsional values exceed workstring connection High flow area around tools for debris passage

Vali Tech® Mag Tech®

 Fluid Interrupter Sleeve (FIS) (Diverter) − Shifting sleeve design  Self modulating by-pass − Eliminates swabbing potential 5

Where it Will Work

▌ CleanWell ® construction system technology utilized in all phases of the well ▌ 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 ® Vac Tech ® eductor system products including 6

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 7
