14 MMSCFD Gas Lift Compression at recently upgraded CTB. We installed a compressor station with 3 Cat 3516’s, 4″/6″ gas lift pipelines, and scrubbers, supporting 14 wells. No shutdown needed, H2S management with Triazene, and provisions for future expansion. Total AFE: $3MM.
Project Spotlight: 14 MMscf/d Gas Lift Compression Installation
We are excited to showcase our recent work on the Gas Lift Compression Station installed adjacent to a Central Tank Battery (CTB) that we previously performed a large expansion on. This project successfully provided gas lift support for the University Lands Wells, which includes three legacy wells and 11 newly drilled or ongoing wells.
Project Overview:
-
The Gas Lift Compressor Station was connected to the well pads via a 4”/6″ FlexSteel pipelines, which had been proactively installed during the oil effluent pipeline project.
-
The design capacity for the Gas Lift Station was 14 MMSCFD, with 1 MMSCFD allocated to each well. The design included design considerations to double the facility throughput to 28 MMscf/d.
-
Compressor suction pressure was set at approximately 50 PSIg, with a discharge pressure of 1,050 PSIg. Pipeflo simulation was used to ensure the target wellhead pressure of 1,000 psig was obtained.
-
Three (3) Cat 3516’s were installed for a total compression horsepower of approximately 3,600 BHP.
- A suction scrubber and discharge scrubber were included in the design.
Key Features and Scope:
-
No Shutdown Required: The project integrated tie-in points to the previously upgraded CTB, ensuring no additional shutdowns were necessary.
- H2S Management: A 96″ Triazene contactor was installed to mitigate the H2S in the produced gas, due to no sour service compression being readily available in the Delaware.
-
Pipeline Installation: The gas lift pipeline was successfully installed, with the piping terminating at the proposed pipe rack location.
-
Lease and Location: A 100’ x 220’ lease space adjacent to the upgraded CTB was secured for the compressor station.
-
Hydrate Control: Glycol dehydration was recommended, however our client chose to mitigate hydrates with methanol injection.
-
Efficient Air Receiver: A dry air receiver was installed for efficient and environmentally friendly compressor startups.
Opportunity and Future Considerations:
-
Provisions for future expansion were incorporated, allowing for an additional compressor to be installed in the future.
- Tie-in points for compressor drains, blowdown, air, and feed gas were integrated during the CTB upgrade, effectively preventing the need for another shutdown.
Exclusions:
-
A compressor discharge scrubber was included in the scope as part of the project design.
Total AFE Value: $3MM
