GILSONITE stabilizes shale formations while reducing torque and drag. GILSONITE helps control HTHP fluid loss by producing a thin, strong compressible wall cake. GILSONITE is stable to temperatures in excess of 350⁰F (177⁰C). GILSONITE is equally effective in both fresh water and sea water drilling fluids.

GILSONITE is primarily utilized as a shale stabilizer in water base drilling fluids.

GILSONITE is normally added in concentrations of 2–4 lbs/bbl (5.7–11.4 kgs/m³) to stabilize troublesome shales.

Transportation of GILSONITE is not restricted by any regulatory agency.

Utilize normal precautions for employee protection when handling chemical products. Utilize appropriate respirator, gloves, goggles and apron. Refer to the Material Safety Data Sheet (MSDS) for this product prior to use.

GILSONITE is packaged in 25 kgs multiwall paper sack.
