Chemical washes are generally thin fluids and cement spacers are thickened, weighted fluids; both are surfactants that aid in mud removal and are additives that separate the mud from the cement to prevent any compatibility problems. Mud removal for oil and gas cementing can be made easy by using our mutual solvents made specifically for the oil industry and drilling operations. Petrochem has five different types including chemical washes for mud thinning and mutual solvents for ORM removal. Please review our Chemical washes & cement spacers shown below.
Petrochem - Oil and Gas Chemical Wash Liquid (P-CWL2) is used to prepare chemical washes & cement spacers for water-based mud systems. This pre-flush system serves as a spacer between drilling fluid and the cement slurry that prevents mud gelation; which normally happens when cement contacts the drilling mud. A poor bond is created between the pipe and the formation because the cement slurry bypasses through the viscous gelled mud. P-CWL2 has a low viscosity and a zero yield point allowing the chemical to have a turbulent flow at very low pump rates. It is the viscosity eddies from the turbulent fluid that sweeps the side of the pipe and formation resulting in excellent mud removal. The end result of using this additive is a clean surface along the face of the casing and formation; thus increasing the chances of generating a good bond with the cement slurry and the pipe and foundation. Know the following when using this additive:
Petrochem - Oil and Gas Chemical Wash Liquid (P-CWL3) is used to prepare chemical wash spacers for both water-based and oil‑based mud systems.
Petrochem - Laminar Flow Spacer Powder (P-LFS) is a water-based Laminar/plug flow spacer fluid used to the bottom-hole temperatures and are used ahead of cement slurries. This spacer fluid separates the slurry and is designed to be compatible with oil-based drilling fluids. This cement spacer can be used in freshwater or seawater with a 37% salt ratio. P-LFS can be pre-hydrated in saltwater systems, but the salt must be added after complete hydration. It is recommended to add a weighting agent if needed. All spacers are designed to be a higher density and viscosity than the drilling mud. Understanding the following for cement spacers:
Petrochem - Mutual Solvent Liquid (P-MS) design offers a wide range of capabilities and can be used alone or with acid, brine crude oil and other hydrocarbon solvents.
The following are direct benefits of using this mutual solvent:
Petrochem - Cement Spacer Surfactant Liquid (P-NSL4) is a nonionic (cement spacer) surfactant liquid, which is pourable to temperatures as low as 42°F and is a highly effective wetting agent in water or in acid based stimulation fluids. It also has the desirable characteristic of leaving both limestone and sandstone water wet.
The following are direct benefits of using this nonionic (cement spacer) surfactant liquid,
