Graphite Lubricant & Viscosifier

PRODUCT DESCRIPTION

The primary function of Deep Black XE™ is to work as a solid lubricant. Deep Black XE™ can bring viscosity in fresh water drilling fluids and in salt water drilling completion fluids.

  • Deep Black XE™ is part of a family of additives consisting of stabilized dispersion of graphite in an environmentally friendly oily medium (low BTEX).
  • Deep Black XE™ provides all functions of graphite lubricants and secondary viscosifier for fresh and salt water drilling fluids.

BENEFITS AND USE

  • Deep Black XE™ uses the new technology concept which means to treat solid particles with a teflonized derivative.
  • Deep Black XE™ with a slippery surface tension free ability to coat the well bore and drill bit and therefore reduces torque and drag which in turn increases ROP.
  • Deep Black XE™M is non-toxic, non-combustible and contains no heavy metals or environmentally hazardous chemicals.
  • Deep Black XE™ provides for high drilling efficiency and minimization of well costs in vertical, inclined and horizontal wellbores, completion and work-over operations, as well as coiled tubing.
  • Deep Black XE™ does not generate damage formation.

ADDITIONAL ADVANTAGES

  • Optimizes lubrication, especially at higher temperatures
  • Inhibits hydration of the clay fraction in shale
  • Reduces wellbore damage, especially vibration induced formation damage resulting from the stick-slip phenomenon
  • Stabilizes rheological properties, leading to greater borehole efficiency
  • Slicks the entire open-hole, casing and drill-string; reducing frictional forces
  • Reduction of torque and drag values
  • Reduction or elimination of bit and BHA balling
  • Significant reductions in tubular and drilling equipment wear.
  • Improved tripping, logging and casing run times
  • Provides additional viscosity to WBM

TREATMENT

  • Deep Black XE™ is easily dispersed and may be added via a hopper directly into the active system or through pre-mixing.
  • Concentration should vary dependent on mud types, density, well path design (anticipated torque and drag) and anticipated formation.
  • Field experience has shown that a treatment of 3.5- 8 ppb to be effective in reducing torque and drag due to brittle formations and pressurized shale.
  • Treatment on maintenance of daily addition of between 0.25 and 0.50 ppb should be made.

PACKAGING

  • 55 Gallon Drum
  • 275 Gallon Tote

PERFORMANCE TESTS

In 4% KCl Base
These test show that additions of Deep Black XE™ from 2.7 to 5.3 gal/m3 can help to get acceptable rheology parameters.
