Civil and Structural Capabilities

We offer the engineer foundations for process equipment, rotating machinery and structures, design of concrete and steel structures and supports, and assessment of existing foundations and structures to incorporate additions to existing facilities.

Modularized Process and Production Equipment

Our team of engineers and drafting technicians design, fabricate and deliver a complete solution of packages that can reduce your field installation costs and have you up and running faster and more efficiently than field-assembled components. We design and fabricate our client’s standards and requirements and provide fully assembled and tested units ready for installation and integration with other units.

LACT_Thumbnails

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.

VRU_Thumbnails

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.

Separators_thumb

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. 

SWD-3D

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. 

Water-Transfer_Thumbnails

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.

Launcher_receiver_01

Launchers & Receivers

Our expansive inventory of rental launchers and receivers are ready to move PIGs through the pipeline,  providing the much-needed services to keep the flow at the optimum and keep the things running.
