Product brief Angl.recto Hydroclean - VAM Drilling

VAM Drilling’s patented Hydroclean is a Hydro-Mechanical Hole Cleaning Device (MCD) uniquely designed to
increase hole cleaning efficiencies while drilling primarily large hole sections of in highly deviated wells. The tool
features fit-for-purpose bladed scallops and grooves producing a number of hydro-mechanical effects resulting in
drilling performance improvements. The Hydroclean has two separate design configurations, one in the form of a
drill pipe joint (HDP) and the other in the form of a Heavy Weight Drill Pipe (HHW), both configured as an add-on to the
drill string. When adequately spaced and properly used, measurable performance improvements can be expected.
These are achieved by eroding or eliminating cutting beds buildup which naturally develop with the drilling process.
Consequently wells clean faster and better with less time spent on cleanups.
The Hydroclean system provides full and immediate degradation of cutting beds while keeping more cuttings in
suspension on the high side of hole where fluid velocity is the maximum. The hydro-mechanical hole cleaning functions
are achieved through the combination of:
Scooping of cuttings and mechanical erosion of cutting beds by each Hydroclean element
Maintaining continuous flow of cuttings in the high velocity annular space of the hole
Sustaining the conveyor belt effect for efficient transport of cuttings along the drill string
Each Hydroclean design comes in range 2 or 3 and is integrally machined over the full length of the pipe.
A portion of the tool joint bearing section is machined to a larger OD with a profile to reduce friction.
The dual OD configuration provides several advantages:
Offset of the bladed section from the borehole wall
Improved mud flow pattern around the pipe OD
Less torque & drag friction than a standard tool joint
Increased wellbore stand-off
Re-enforced hardbanding
Application Benefits
Case histories have shown operating cost reductions
with up to 20% less non-productive time thanks to:
Reduced bottoms up circulating time
Fewer wiper trips
Less or no back-reaming
Elimination of sweeps
Better and faster hole cleaning
Lower annular pressure
Trouble-free BHA trips and casing runs
Bigger cuttings
More time spent drilling
Higher ROP
Extended service life of the drill string

Hydroclean - HDP
Hydroclean - HDP is manufactured with a welded construction design featuring a dual OD tool joint and three bladed upsets machined directly onto
the pipe body. Standard casing friendly hardbanding is also applied. On average HDP is 20-25% heavier than standard drill pipe.
HDP is operated with standard rig handling equipment and may require switching top drives in manual mode when operated in automatic.

Hydroclean Heavy Weight - HHW
Hydroclean Heavy Weight - HHW is manufactured in a mono-block construction with two bladed upsets machined directly onto the tube body.
HHW is run with conventional heavy weight drill pipe. Experience has shown that placing HHW as near as possible to the large OD BHA components
can significantly reduce the risk of pack-off in this critical area.
