- 13. Conventional Tree SelectionIssues Advantages Completion can be installed after drilling without removing the BOP. This precludes the need to kill the well and install barriers. Swab barriers are gate valves. Tree can be retrieved without disturbing the completion. Riser loading on tree is relatively low. Disadvantages Lack of readily available dual bore Installation / Workover Riser for Deepwater and 15ksi. High weight of dual bore riser inside marine riser exceeds Compensator capacity. Lack of annulus access for mono- bore Risers. Requirement for Completion Guidebase to achieve Tubing hanger orientation. Requires BOP Pin for TH Orientation. Incompatibility between different wellhead and tree suppliers. Does not support large bore completions (> 5-1/2”) and multiple down hole penetrations.
- 14. Horizontal Tree SelectionIssues Advantages Availability of interchangeable rental tools & SSTT packages Availability of lightweight monobore installation riser Passive orientation of Tubing Hanger preset and factory tested Supports large bore completions Supports large number of downhole functions Simple interface between Wellhead and Tree Reduced time for major workover and re-completions. Disadvantages Well clean up and testing requires to be performed inside drilling riser Swab barriers are crown plugs Potentials for drilling mud and completions fluids ingress into Tree valves Riser debris accumulation on top of tubing High drilling riser loads on Tree

Summary – TreeSelection Factors Field Logistics – Drill & Complete vs. separate campaigns Number of wells – drives tooling flexibility Water Depth – limits tooling capability & availability Completion Size & Complexity – HT advantage Planned Major Workovers – HT advantage Artificial Lift – HT advantage Planned Minor Workovers – CT advantage Tree Complexity/Reliability – CT advantage Tree Weight – CT advantage (w/ THS)

- 27. Jack Up DrillingRig Capabilities JUDR are VERY attractive from a cost perspective…… If they can meet the operational need? Primary function is to drill. Not subsea tree completion Surface BOP reduces induced loads allowing use of 13 5/8” systems Relatively shallow water facilitates the use of jack up drilling rigs Jack up drilling rigs generally have reduced capability when compared to a Semi Semi Day rate = $250 – 300k JUDR Day rate = $90 – 120k
