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
