HDD Fluid Programme by Formation
Clay, sand, gravel, cobble, competent rock and fractured ground require different fluid functions. Use this formation decision center to route the project toward the smallest product system that solves the actual field mechanisms.
Start with the ground condition
Choose the dominant formation to see the main field risks and the product functions that normally become relevant.
Swelling · stickiness · dispersion · high solids
Bore support · filtercake · filtration
Heavy cuttings · bridging · lost circulation
Hole cleaning · friction · fracture losses
Change the product function as the formation changes
Identify clay, sand, gravel/cobble, rock/fractures or mixed ground.
Check hardness, calcium, pH and salinity before judging product performance.
Pilot, reaming and pullback change the dominant fluid requirement.
Returns, solids, torque, fluid loss and whole-mud loss determine the next function.
Reactive clay: separate inhibition from encapsulation
MUDOCLAY-OFF addresses clay hydration/swelling; POLYWELL and DRILL-WELL support encapsulation and reactive-solids control. MUDOZAN is added only where suspension requires more support, and water conditioning comes before all of them.
MUDOCLAY-OFFReactive Clay Inhibitor & StabilizerReactive clay inhibitor and stabilizer for water-sensitive clay and shale in compatible drilling and completion fluids.

View product →Sand: build bore support and control filtration
ALKABEN provides the bentonite base where structural support and filtercake are required. MUDOPAC-LV/HV or MUDOFIL-CMC refine filtration according to how much rheological contribution is desirable.

View product →Gravel and cobble: know when whole-mud loss begins
MUDOZAN supports heavy cuttings, while SEALFIBER and FRACPLUG address larger loss pathways when returned volume confirms that the mechanism has moved beyond ordinary filtration.

SEALFIBERFibrous LCMFibrous lost circulation material for bridging and sealing permeable zones.

FRACPLUGSwelling LCMSwelling lost circulation material for fractures, voids and highly permeable formations.
View product →Rock and fractures: clean first, lubricate second
Competent rock emphasizes heavy-cuttings transport and MUDOLUBE only after cleaning is acceptable. Fractured rock can shift the programme toward SEALFIBER/FRACPLUG if whole mud is being lost.

View product →Mixed ground: use an adjustable function-based programme
A long bore can move through clay, sand, gravel and rock. The base formulation should be adjusted by formation and stage instead of forcing one fixed recipe from entry to exit.

View product →Water and drilling stage modify every formation decision
Pilot, reaming and pullback change cuttings volume and friction. Hard or saline water changes hydration. Use field testing and current returns to decide which function is actually missing.
Do not use one universal HDD mud recipe from entry pit to exit pit
The formation, make-up water, reamer size, returns and solids load change through the crossing. A technically credible programme changes the product function when the dominant mechanism changes.
What Mudolog needs from you
Send the field variables that change the fluid decision. A short, technically complete HDD RFQ is more useful than a generic request for “mud chemical price”.
