Lease Automatic Custody Transfer (LACT)

The Lease Automatic Custody Transfer (LACT) unit or Automatic Custody Transfer (ACT) unit is one of the most critical elements in custody transfer for crude oil and petroleum products from the production facilities to trucks, railcars, pipelines or storage tanks.


Vapor Recover Units (VRU)

Our Vapor Recovery Unit (VRU) units are designed to remove unwanted vapors such as gasoline and other fuels that may be present in crude oil or distillate tanks, allowing operators to comply with prevailing emission regulations to reduce noxious and potentially explosive fumes and pollution.


Production Phase Separators

Produced well fluids consist of various amounts of oil, water, natural gas, and sediment.  Our three-phase separators are engineered and fabricated to the highest standards to deliver the necessary performance and help you reduce Lease Operating Expense at shale plays and oilfields. 


Water Disposal & Waterflood

Our Salt Water Disposal (SWD) units help keep your E&P operations on track and operating at peak performance. Our state-of-the-art control logic gives us the unique ability to modulate the flow of your facility to meet varying conditions and gives you superior access to safe and environmentally compliant solutions for your oilfield waste. 


Produced Water Transfer

Whether by pipeline or truck, our extensive knowledge of hydraulics ensures a total water solution for oil and gas exploration and production in the form of permanent pipeline transport facilities and water infrastructure services. With multiple pump technologies available, we select our equipment based on the correct fit for your application.


Launchers & Receivers
