BaraECD™ Customized Weighting Materials
Less than 4 micron d-50
Small particle size slows settling rate
Acceptable settling rate with reduced fluid rheology
Micronized weighting agents
Describes relationship of viscosity with density and particle size
Does not consider any interactions of components within the fluid
Uses principles of Stokes law
Vs = Particle settling velocity
R = Particle Radius

Case Histories – BaraECD™ Fluid Wells Drilled
15© 2014 HALLIBURTON. ALL RIGHTS RESERVED.
CHALLENGE: Gulf of Mexico well with increased sag potential, high angle
wellbore Elevated ECD, 6.5-inch hole, window milled out of 6.625-inch
ID casing Differential Sticking and lost circulation hazard, depleted sand
9.3ppg EMW, 3,000 psi overbalance Increased potential of fracture-induced lost circulation, 13.7
ppg surface mud weight, 14.8 ppg fracture gradient in depleted sand
SOLUTION: BaraECD™ Fluid System applied Halliburton Hydraulic Shear Unit used to pre-condition fluid
RESULT: BaraECD fluid reduced ECD by 0.47 ppg and stayed below
fracture gradient Section was drilled successfully with no indications of barite
sag Losses were mitigated with no differential sticking issues
Case History – BaraECD™ System Location: Gulf of Mexico
