EC-Drill® Dual MPD

Rapid influx suppression, Controlled riser gas handling, Influx Management (IME), Dynamic Pore Pressure testing, Dynamic FIT and LOT
Reduce casing strings in the well design with the dual gradient effect which has saved USD 5 million+ per reduced casing string. This will also increase production with larger hole size in the Reservoir
Precise Volume Control during all well operations, even in harsh weather conditions. Providing early kick and loss detection. Influxes are detected faster, reduce influx volume and time required to safely deal with them, as well as ensuring quickly response to and mitigation of losses
Save rig time and improve operational efficiency. Faster, and safer tripping. Avoid time consuming mud displacements; change effective mud weight in minutes not hours
Achieve barrier requirements with Managed Pressure Cementing. Easy to apply to challenging cement operations. Improved well integrity. Replace expensive and complex specialty cements (Foam Cement, Lightweight blends and chemicals)
Increase production and achieve completion goals. Complete wells that cannot be completed conventionally, releasing stranded reserves. Perform text-book Open Hole Gravel Packs, even in depleted reservoirs. Proven increase in production by 20% to 40% compared to offset wells
Save Rig Time and Improve Efficiency. Well control studies have found that up to 70% of kicks occur when tripping. Tripping and Running with adjusted riser fluid level: Precise monitoring of volume in riser; Adjust fluid level in riser as required to compensate for surge/swab; Trip faster and safer regardless of depth and pipe size
Adjust Riser Fluid Level when tripping, cementing, and drilling instead of displacing the well. 6 to 12 hours saved per displacement. Avoid having multiple mud systems on board
Adjust the Bottom Hole Pressure (BHP) to manage depletion, pressure-ramps, narrow windows. Change BHP in minutes not hours

Adding SBP functionality to CML, with he SBP advantages:

Rapid influx suppression
Controlled riser gas handling
Influx Management (IME)
Dynamic Pore Pressure testing
Dynamic FIT and LOT

While avoiding the SBP disadvantages:

Flat time with deployment and changeout of RCD (To be able to drill ahead with SBP a Riser Closure Device (ACD or DA) would be required)
Underbalanced drilling MW
Added time for stripping and displacements
Large pressure variations between dynamic and static

And maintaining the CML flexibility and advantages:

Quick detection of influxes and losses
Volume control in all conditions (static and open hole)
Remove rig motion effects
Overbalanced fluid – fails to safer state
Surge mitigation while running casing/liners
Managed Pressure Cementing
Managed Pressure Gravel Packing
High uptime
Low OPEX
