VersaFlex ® Big Bore Liner Hanger Systems TECHNOLOGY BRIEF

1. VersaFlex® Big Bore Liner Hanger Systems TECHNOLOGY BRIEF James Williford Global Product Champion

2. What is it? • Halliburton’s Big Bore VersaFlex® expandable liner hanger (ELH) system is designed specifically for the deepwater and subsea markets and is ideal for complex well conditions. • The liner hanger is designed to replace the mudline/casing wellhead profile. It is designed to help operators reduce both risk and capital costs. VersaFlex® Big Bore Supplemental CSG HGR

3. How it will Benefit you • Proven reliability • “Set and forget” – design simplicity helps eliminate risks associated with conventional liner hangers • Improves wellbore integrity • Solves issues associated with larger casing strings installed in deepwater or subsea wells • Holds in tension and compression during the life of the well • Sets in deviated wellbores • Improved bypass area for reduced ECDs

4. Why it will Help • Eliminates the need to land casing at a fixed point and provide casing placement flexibility • Improved casing support reliability by allowing setting the hanger at whatever depth that gives best integrity to the string • Provide excellent liner-top seal • Improves cement integrity by providing rotation and reciprocation capability during cementing • Ability to work the pipe gives the best chance to reach total depth. • Mitigate casing placement risks

5. Unique Features • Simplified installation – operational steps cut in half compared to conventional systems • Fully integral hanger/packer design • Minimized potential leak paths • Designed to hang 13 3/8-in. – 18-in. liners • Large radial clearance (clean-form design)

6. Where it Will Work • VersaFlex® Big Bore liner hanger system is designed for subsea and deepwater application with the intention of overcoming failures and complexities intrinsic to supplemental casing adapters. • Big Bore setting tools are designed for high-rate washing, reaming, and even drill-in with liner capabilities where necessary.

7. Challenges Addressed • When running supplemental casing adaptors, operators have less than a two-degree margin-of-error for avoiding leaks while landing this type of adapter. VersaFlex® Big Bore system’s rotation and reciprocation capability eliminate the risk. • VersaFlex Big Bore system’s rotating and reciprocation capability during cementing allows for zonal isolation integrity. • System is ideal for extreme well conditions and its high-torque rating permits reaming through downhole cave-ins, kicking-off ledges from previously drilled segments, and drilling new hole sections.

8. When its Helpful • VersaFlex®Big Bore system is highly praised for its placement flexibility in deep and ultra-deepwater regions. • If the liner is not fully deployed and landed on depth, the supplemental casing hanger does not offer any means for washing or reaming to depth, which presents a potential for millions of dollars to be spent in remedial repairs. With the VersaFlex®Big Bore system, however, operators are not forced to weigh high-risk procedures against liner-cost savings.
