LOPAC™ provides filtration control and stabilizes the rheological properties of most water base drilling fluids. LOPAC™ provides fluid loss control and gives low plastic viscosity values when added to the drilling fluids. LOPAC™ is effective in fresh water and salt based fluids and at low concentrations has the ability to reduce the rheology of flocculated and high solids fluids. LOPAC™ has a strong affinity for clay surfaces and will restrict their hydration and dispersion. LOPAC™ is not susceptible to bacterial attack. LOPAC™ has shown to provide stable filtration control at bottom hole temperatures in excess of 300⁰F (149⁰C). LOPAC™ has a high tolerance to divalent ions and is effective over a wide pH range.

LOPAC™ will control fluid loss in most water base drilling fluid system with little or no effect on viscosity.

Concentrations in the range of 0.25–3.0 lbs/bbl (0.7–8.6 kgs/m³) are required to maintain filtration control with LOPAC™. The actual treatment will depend upon the composition of the drilling fluid and drilling conditions encountered.

Transportation of LOPAC™ 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.

LOPAC™ is packaged in 25 kgs multiwall paper sack.
