Saltwater disposal

Get everything you need for your saltwater disposal facilities

Saltwater is a byproduct of oil and gas production. In fact, water cuts often exceed oil cuts in the production stream, especially as wells age and water-to-oil ratios increase. Producers typically dispose of the saltwater by injecting it back into deep, porous rock formations in a non-producing well. This process protects groundwater and surface water from contamination.

SLB designs, fabricates, commissions, and services equipment for saltwater disposal (SWD) facilities. From pump sizing to full designs, SLB has extensive knowledge to engineer and manage SWD surface equipment projects that fully integrate into complete operational facilities.

• SWD injection skids for disposal wells in onshore basins
• Produced water transfer between tanks, vessels, and pipelines
• Truck-unload / offloading where operators require fast turnaround and solids protection
• Filtration trains to remove solids prior to injection and protect downstream equipment

• Get more uptime with complete, matched pump-and-control packages engineered for the application, reducing unplanned trips
• Lower maintenance burden with options like slow-speed auxiliary lube, packing lubrication, and correctly sized dampeners extend service life
• Mitigate solids with backwashable, cartridge, and bag filtration options limit solids carry-over to injection equipment
• Get operational visibility using variable speed drives (VSDs) to improve control and optimize your site

• Injection pump packages:
  • Multiplex plunger pumps
  • Reda HPS™ horizontal multistage surface pumping system
• Charge and transfer pumps: ANSI charge / transfer pumps in horizontal or vertical configurations; coupled / close-coupled; carbon or stainless materials; packing or cartridge seals.
• Truck-offloading systems: Centrifugal or gear pump options plus strainers / filters / hydrocyclones to keep solids out of the system.
• Filtration systems: Backwashable, bag, or cartridge filters; manual to automated operation depending on solids load and maintenance strategy.
• Controls and automation: Tank level, pressure, and flow controls; VSDs; soft starters; automatic bypass valves; gas detection (LEL) integration.
