Ennor Muds And Chemicals

• EN- CA - R1 (Low Temperature Retarder) : This is the low temperature retarder EN-CA-R1 used widely for effective application as these do not take excess time for thickening and does not forms viscosity humps (high viscosity after heat up). This is highly recommended for API cements or for that cement that has high salt or gel concentrations and do not react against other cement retarders.

• EN- CA - RHT (High Temperature Retarder) : Our array of EN-CA-RHT high temperature retarder is used exhaustively for all kinds of cementing operations such as casing cementation, cement plugs and squeeze cementing that has high temperatures.
  

• EN- CA - FR1 ( Friction Reducer) : Our range of EN-CA-FR1 friction reducer is used for those cement systems that has more than 18% salt concentration than the exact weight. This allows high density slurries to be mixed and pumped.
  

• EN- CA - FL8 (Fluid Loss Control) : Our array of EN-CA-FL8 is a fluid loss control compound that is used widely for cementing operations to provide effective water loss control in saline water slurries. These are used widely exhaustively in the following applications:

• Primary cement operations i.e., casing string cementation
• 'Squeeze' cementing, i.e., lost circulation problems,
• Casing repairs,
• Performation sealing
• Setting cement plugs (especially across permeable formations)

This stabilizes cement systems for use in deep, high temperature wells and slurries used for cementing geothermal wells or where thermal recovery will be used in the future. This is beneficial in preparing low density slurries where settling can take time and hence is preferred for compressive strength or in highly dispersed cement that allows coarse silica to settle. This is compatible with all API class cements and is used commonly as additives.
 

• EN- CA - MS (Microfined Silica) : This is EN- CA - MS   Microfined Silica used widely in cementation and it differs from silica flour in the mesh i.e microfined silica’s mesh size about 1000 to 1200 mesh.

This allows larger quantities of mix water without free water separation. This produces a lower density and a higher slurry yield that enables cement to be mixed from 11.4 to 17.0 lb/gal. Further this accelerated the strength development of the cement.
