Product Desciption

Viscoelastic Diverting Agent VDA - Diverter for HCl VDA Acid Fracturing Fluid up to 176 degF
Applications

1.Reservoirs with high permeability contrasts and/or natural fractures.

2.Bottomhole temperatures 176 degF .

3.Carbonate oil or gas wells.

4.Open hole or cased hole intervals, regardless of deviation.
Fluid and petro-physical heterogeneities are encountered in most sandstone and carbonate formations. Chemical diverter technology is one of the methodologies to be used in stimulation treatment to divert treatment fluids from high water cut layers to low water cut layers, and/or from high permeability zones to low permeability zones. Viscoelastic Diverting Agent is a non-damaging chemical diverter used in stimulation fluid systems to improve treatment fluid distributions across formation matrix to increase stimulation efficiency.

Advantages

1.Degrades completely, eliminating risk of costly cleanout interventions.

2.Targets permeability contrasts, allowing superior zonal coverage.

3.Effectively controls leak-off.

4.Requires lower treatment volumes and less well cleanup time.

Features

1.Diverts effectively at low treatment rates.

2.Continues to stimulate as it degrades.

3.Can be bullheaded or pumped through CT.

4.Can be pumped with most common acid stimulation systems.

5.Can be batch mixed for small volume jobs or mixed on the fly for larger treatments.

Chemical Properties and Application
1) Viscoelastic Diverting Agent is a surfactant based chemical diverter which is very effective in distributing treatment fluid homogeneously across treatment zones in stimulation treatment at various well conditions.
2) Viscoelastic Diverting Agent forms viscous micelle structure when its concentration reaches certain level in water or brines. The viscosity breaks dramatically when it contacts with hydrocarbon or crude oils. The in-situ viscous behavior of Viscoelastic Diverting Agent in aqueous solution will divert treatment fluids from high water-cut to low water-cut, from high permeability to low permeability zones of the rock matrix. The matrix is therefore stimulated homogeneously.
3) Viscoelastic Diverting Agent is compatible with most additives in stimulation fluid systems. Some additives such as corrosion inhibitor or solvent may have adverse effect on Viscoelastic Diverting Agent rheological properties. Compatibility testing is generally required when Viscoelastic Diverting Agent is used in stimulation treatment.
