…A Move to MPD Systems – Post-BOP
• RMR® is Pre-BOP….top-hole management and improvement…it is used in open water, before the BOP is run.
• …let’s transfer that RMR® experience….to….EC-Drill® …
• …that is… to subsea MPD Techniques:
EC-Drill® …pre-BOP on Jack Up wells.
EC-Drill® …post-BOP on deepwater floater wells.

EC-Drill® - Floater Rig
• Single gradient when static.
• Single gradient when dynamic, but
with lowered mud level in the riser.
• Precisely controls mud level for
desired BHP…to compensate for
ECD effect.
• Conventional well control.
• Modified Riser Joint to dock SPM.
• Built on RMR equipment/techniques.

• Safer working window.
• Push casing setting depth deeper.
• Save casing string for later.

Feedback from Cuba Operations • 3 wells drilled:
o 1st well - some equipment problems,
o 2nd well - good performance,
o 3rd well - good performance.
• EC-Drill® run in 17-1/2” and 12-1/4” hole sections.
• Manipulated the riser fluid level in a window of 150 to 200m below
RKB with 1650 gpm flow in the 17-1/2 in. section.
• No losses or hole instability issues seen.
• ROP gains observed when BHP reduced.
• No gas recorded at top of riser.
• With planning, reasonable timeframe to implement on floater rig.
• Builds on conventional well control techniques, does not replace
them.
Enhanced Drilling
EC-Drill® Applications
• Real time ECD compensation:
– Drilling
– Tripping
– Running casing
– Cementing
• Well types
– Narrow windows
– Weak zones
– Depleted fields
• Used in conjunction with conventional well control techniques/procedures.

Enhanced Drilling
EC-Drill® Direction
• First 3-well deepwater, Post-BOP wells have been drilled and
lessons-learned gathered for improvements.
• Now working on:
– Pump enhancements,
– MRL improvements to soft line and development of hard line option
integrated into drilling riser,
– Control system enhancements,
– Further competency training programs for AGR personnel.
• These improvements are being implemented in our Norway
Troll Field Project… now - 2013.

From RMR® To EC-Drill®
• AGR has built a significant technology footprint and IP portfolio.
• With many years & many wells of RMR operational experience.
• We have now crossed the threshold into post-BOP, subsea MPD
operations.
• EC-Drill® subsea MPD services are now in use on active
drilling operations…shallow water and deepwater…!
