120 MMSCFD COMPRESSOR SITE EXPANSION

Supporting Production Growth

LOCATION: Gilette, WY
MARKET: Pipelines & Gathering Systems

THE CHALLENGE

Growing gas production necessitated our client expand one of their compressor stations, doubling the capacity and total installed horsepower. The original design of the low-pressure inlet was originally designed for two slug catchers, leading to concern over liquid management onsite. The high-pressure inlet did not allow for blending for dehydration optimization. Late into execution of the project, the existing high-pressure 3-phase separator was upsized to improve liquid removal and dehydration performance.

THE SOLUTION

Developed a plan and budget:

• Executed onsite visits and as-built documentation of existing facility
• Reviewed operational improvements for the expansion
• Developed design basis to capture required project technical requirements

Source new equipment:

• Low-pressure inlet slug catcher
• High-pressure 3-phase separator
• Motor Control Center (MCC) expansion

Execute value engineering to support the project schedule:

• P&ID generation
• Equipment evaluation
• PSV sizing calculations and safety review
• Engineered valve specification
• 3D modeling
• Construction packages for electrical, mechanical, and civil bids
