…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.

Current Phase – Norway Qualification

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…!
