Cementing Additives

Cement supports and protects well casings and helps achieve zonal isolation. Critical to safer, environmentally sound, and profitable wells, zonal isolation is created and maintained in the wellbore by the cementing process. Whatever your drilling environment or however remote the location, Midas China innovative cementing technologies offer you a range of cementing solutions to achieve zonal isolation for the life of your well.

Cement Retarder by Midas
Cement Retarders


Cement setting times can be adjusted with retarders. Midas Cement retarders control the time when a slurry will set hard, keeping the slurry viscous and pumpable in expected wellbore temperatures and for the amount of time required to place the slurry.

Retarders decrease the rate of cement hydration, acting in a manner opposite to that of accelerators.  


- Retarder for High Temperature / Low temperature 

                       Salt water / Fresh water

Fluid Loss Control by Midas
Fluid Loss Control Agent (FLC)


Fluid loss Control additives help operators retain the key characteristics of their cement slurries, including viscosity, thickening time, density and compressive strength development.

Sub-Categories :

- FLC for Fresh water / Salt Water

- FLC for High Temperature / Low Temperature

- Available in Liquid form

Oilfield Surfactants  by Midas
Surfactants for Oilfield Cementing


Midas surfactant that is added to the spacer pill to enhance the cleanout of oil substrates through an ultra-low interfacial tension, helps leave the pipe and formation in a water-wet condition, is applicable over a wide temperature range and is environmentally friendly.

Oilfield Cement Spacer and Flushes
Cement Spacer & Flushes

Midas Oilfield Chemicals offers spacers and flushes to help operators improve the probability of returning uncontaminated mud to the surface and securing a successful primary cement job.

Spacer is a viscous fluid used to aid removal of drilling fluids before a primary cementing operation. The spacer is prepared with specific fluid characteristics, such as viscosity and density, that are engineered to displace the drilling fluid while enabling placement of a complete cement sheath.

Cement Dispersant by Midas
Cement Dispersant


Adding dispersants can lower friction and lower pressure during pumping, enhance turbulent flow at reduced pumping rates, and allow operators to mix densified cement slurries. Midas Dispersants can also be used to help reduce pressure exerted when placing cement across unconsolidated sands, depleted or weak formations, possibly preventing lost circulation.

- Dispersant for Fresh Water / Salt Water

Anti Gas Migration by Midas
Anti-Gas Migration


Gas migration is defined as gas entry into a cemented annulus creating channels with the potential to provide a flow path of formation fluids, including hydrocarbons, into the wellbore. This can cause gas/fluid flow in the annulus and can usually be detected by cement bond logs and/or by noticing unwanted pressures. Hydrostatic pressure loss before the cement slurry has achieved sufficient static gel strength to resist gas flow which can contribute to gas migration.

Oilfield Chemical Wash
Oilfield Chemical Washes


A fluid, generally water-based, to thin and disperse mud in preparation for cementing. The chemical wash is pumped ahead of the cement slurry to help ensure effective mud removal and efficient cement placement.

Oilfield Solvents
Solvents for Oilfield Cementing


Midas Mutual solvents serve as water wetting agents, de-mulsifiers, and interfacial tension reducers. The contacted organic films are left water-wet help to eliminate emulsions and particle plugging.
