Well Commander

Mitigate drilling hazards with the industry’s most versatile drilling valve.

Spot pills and increase circulation exactly where you want, with no impact on the BHA, logging tools or the bit……..

CONFIDENTIAL INFORMATION ©2009 M-I L.L.C.

Well Commander Features• Run in Directional Drilling Assembly above

turbine/mud motor or other BHA components• Generous flow-through area via multiple ports• Ball catcher has a 14 or 18 ball capacity (7 or

9 complete cycles)• Patented Ball Seat Technology utilizes the

same-size ball opens and closes the ports to simplify operating procedures

• Available in 5”, 7” 8-1/4” & 9-1/2” OD w. variety of connections inc. standard & premium

• No internal tool connections• Tool activation mechanism locks into open or

closed position• Tool activation mechanism isolated from

circulating fluids• Ball catcher permits smaller ball and/or

limited wire-line access below tool• Optional shut-off ball prevents coarse LCM

from entering sensitive bottom hole components

Well Commander Benefits• Easy spotting of LCM or WSM while drilling• Cuttings-beds removal, enhanced hole cleaning

and efficient fluid displacement by boosting annular velocities in conjunction with pipe rotation

• Will not function prematurely from high circulation or tripping rates

• Saves tripping time; multiple trips without redressing the tool

• Simplifies reverse circulation through the tool• Boosts annular velocities above an under-reamer

for enhanced hole cleaning• Elevates circulation rates with minimal pressure

drop• Functions in water or invert-emulsion drilling

fluids as well as clear brines• Provides jetting functionality in the BOP• Permits running other ball-activated tools below• Permits limited wire-line access for free-point

indicators or other elements• Promotes filling or draining the work-string while

tripping4

Well Commander Function• Activation ball is pumped down and

lands on ball seat• Pressure is applied which compresses

the internal spring and indexes the tool

the internal spring and indexes the tool

• The ball seat deforms and the ball is ejected into the Bypass Ball Catcher

• The circulation ports are now open to the annulus allowing increased circulation

Advanced Ball Catcher Function• The Bypass Ball Catcher collects the

Activation and BHA Shut-Off Balls• A smaller ball is dropped to activate

another BHA component (under-reamer)

• The ball passes through the Ball Seats without effect

Well Commander - Key Design Features

13

• Short one piece mandrel with no internal connections• Seals remain stationary and port slides past sleeves for increased

reliability• Rotational motion of activation sleeve reduced internal friction• Disc springs provide high compressive strength• Tool internals are oil filled in workshop• Floating Piston equalized tool internal pressure to ensure no ingress of

drilling mud and solids• Floating Piston design prevents possibility of hydraulic locking• Exit port design reduced erosion potential• 4330V material ensures tools high strength confirmed by Finite

Well Commander SummaryA P P L I C A T I O N SExtended-reach drilling, spotting Lost-Circulation Material (LCM) or kill-weight fluid, under-reaming, underbalanced and managed-pressure drilling, conditioning or displacing at high flow ratesP R O B L E M SRestrictive BHAs can limit flow rate and annular velocity preventing effective hole cleaning while drilling or displacing wellbore fluids.These BHAs can also limit the size and concentration of LCM or Wellbore-Strengthening Material (WSM) that can be placed in troublesome zonesS O L U T I O N S The Well Commander mitigates drilling hazards by providing large bypass flow area and up to seven open-and-close cycles in one trip.E C O N O M I C SThe high flow rates reduce circulating time saving money when in spotting effective LCM/WSM treatments or kill-weight fluids and during displacements. High flow rates assist removal of cuttings beds preventing packoffs in extended-reach wells.E N V I R O N M E N T A LWork-strings can be drained or filled during tripping by bypassing BHA. Slugs can work at any angle avoiding spills and promoting a safer work environment.
