LAKOS desanders have been successfully used to separate solids from water and other liquids in the oil and gas industry. Oil and gas operations are typically divided into upstream applications and downstream applications:

Upstream Applications (LAKOS product focus)
Exploration, Development, Drilling, Production, Gathering, Treating, Disposal, Pipelines, Transportation

Downstream Applications
Storage, Refining, Gas Processing, Petrochemicals, Distribution, Retail Marketing

Produced Water (EPP desander)
Remove sand prior to reinjection or disposal; protect oil-water hydrocyclones; reduce sand accumulation in FWKO tanks and heater-treaters.

Primary Filtration (EPP desander)
Prefiltration to bag filters, media filters, and cartridge filters for produced water and intake water supply.


Secondary Recovery (EPS desander)
For use in waterflood injection and to protect finer filters and high pressure pumps while protecting formations.

Solids Buildup Prevention (EPP desander)

Downhole Pump Protection (PPD desander)
Remove sand from production fluids before it enters a downhole pump; increases the run life and efficiency of pumps.

Produced water system reduces downtime with LAKOS
At a Renaissance Energy site in southwest Saskatchewan, sand in the free water knock out (FWKO) and heater-treater tank was causing an extensive system shutdown every 4-5 months before LAKOS Separators/Desanders were installed to eliminate the sand accumulation and lost efficiency. Savings attributable to the increased productivity exceed $100,000 per year at this site alone. Other sites have all now been targeted for LAKOS installations.

Separator protects oil/water cyclone at waterflood injection site
Replacing a bag filter system with greater efficiency, lower pressure loss and reduced maintenance capabilities, a special 600 psi LAKOS Separator/Desander extends the life of an oil/water hydrocyclone by removing abrasive sand from produced water used for injection well applications.

Sandy river water cleaned with LAKOS for injection wells
Removing sand from river water prior to use for injection wells, a LAKOS Separator/Desander helps Crestar Energy in Alberta, Canada avoid extensive maintenance on their final stage ultrafiltration before high pressure injection.

Waterflood injection wells depend on LAKOS
Over fifty injection well systems at the Denver City, Texas oil fields of Shell Oil Company rely on LAKOS Separators/Desanders to protect their high-pressure injection pumps from sand & grit abrasion. Installed on the discharge of their water well pumps before feeding water to the injection pumps, the LAKOS Separators help maintain the porosity and permeability of the underground formations for optimum oil recovery operations.
