SL-DEM01 is used in acid fluids. It is a good emulsion-preventing agent to be used to prevent emulsions caused by acid mixing with the produced oil. The flowback rate can be also improved efficiently.

De-Emulsifiers SL-DEM01
In the process of fracturing and acidizing of oil wells production operations, working fluid flows through the reservoir at high speed, forming the emulsion with the crude oil. And then the reservoir’s permeability declined. This matter seriously affects the well fluid flowback velocity and the oil well production.

Product Description
Technical & Engineering Information
SL-DEM01 is a surface-active substance that relies on chemical action to destroy the structure of emulsified oil-water mixed liquid to achieve the purpose of separating the phases in the emulsion.
SL-DEM01 works by firstly removing the emulsifying agent and secondly coalescing the water droplets that then separate by gravity, achieving dry oil with low salt content as well as minimal oil in the separated water.
SL-DEM01 is designed to give rapid separation of oil and water along with a sharp interface and good water quality and can be designed to desalt crude if required.
SL-DEM01 is compatible with most additives in stimulation fluid systems. It is also readily biodegradable and presents lower toxicity to organisms than other surface-active agents.

Recommended Treatment
SL-DEM01 is generally injected into produced fluids at a point, upstream of the 1st stage separator.
Field experience shows that typical dose rates are in the region of 5 - 50ppm, based on the total volume of produced fluids.
Formulating the correct demulsified to maximize water removal should always be performed in the field using fresh emulsion, as every emulsion is unique and related to the field as well as process conditions. Emulsions also age, becoming more difficult to break over time, meaning a delay during transportation of crude is not viable.
Normal practice is for a field trial to be carried out prior to bulk purchase.
Packing and Storage
SL-DEM01 be packed in 200L HDPE or 1000L IBC.
Be kept away from moisture and possible damage of the packages in transportation, stored in cool places and away from direct sunlight.
Shelf life: 1 year.
