Project Description

The Anadarko Salt Creek Production Facility is an Enhanced Oil Recovery facility treating oil production from a CO2 flood. The target production is 6,400 BOPD associated with 64,150 BWPD and 14.8 MMSCFD gas. At the production site, manifold locations separate CO2 gas from the produced liquid stream at 400 psig. The liquid stream then flows to the treatment equipment to ensure water is treated to discharge specifications for Salt Creek.

There are two (2) trains of equipment required for the Salt Creek facilities to dehydrate the oil to 0.4% BS&W. Each train is designed for 75% of the total produced fluids.

The facility includes the following equipment to separate the gas, oil and water to commercial specification:

  • Flow Splitting: Porta-Test® Tee Splitter
  • Primary Separation System: Low Pressure 3-Phase HLF Separators
  • Produced Water Treatment System: Water Skim Tank

The design and performance of the equipment is based on using patented and proprietary NATCO devices including: Porta-Test Revolution®, Performax®, Porta-Test® Flow Splitter (patent pending) and Skim Tank Internals designed using Computational Fluid Dynamics (CFD)

Scope of Supply

NATCO Process Solutions Team conducted a FEED study followed by a project award to supply process design, detailed engineering, equipment fabrication for the Porta-Test Tee Flow Splitter and two trains of 3-Phase separators to be installed in the Salt Creek EOR facility.

The project was managed between NATCO and AMEC Paragon for Anardarko. All equipment was fabricated at NATCO, New Iberia, LA facilities. The vessels were internally coated are all the stainless steel internals are removable. The vessel high performance internals include Porta-Test Revolution as inlet device and Performax coalescing media, as the coalescing media.
