Production

• As of 2020, the asset produced 0.9 million m³/y of gas and 0.19 million bbl/y of oil.
• By 2022, production had increased to 1.89 million m³/y of gas and 0.25 million bbl/y of oil.

Facilities and Infrastructure

• The project involves several offshore platforms designed and constructed by Audubon Companies for Helis Oil & Gas. These include:
  • Three 6-pile and one 4-pile, steel-jacketed facilities.
  • Facilities designed for produced water injection, with a capacity for 80,000 barrels of water per day (BWPD).
  • Oil production capacity of up to 6,000 barrels of oil per day (BOPD).
  • Gas production capacity of up to 50 million standard cubic feet per day (MMSCFD).
  • The platforms include 32-man quarters and are designed to Gulf of Mexico (GOM) standards.

Scope of Work

• The scope of work by Audubon Companies included front-end engineering design (FEED), detailed design, facility design, structural design of decks and jackets, and various engineering services such as process, electrical, instrumentation, mechanical, and piping designs.
• Additional services included project management, installation supervision, construction management, and commissioning and start-up support of the facilities.
• Specific systems included compression, gas dehydration, gas lift systems, gas sales, de-sanding and de-oiling hydrocyclones, separation, oil treating, dehydration, and lease automatic custody transfer (LACT) systems.

Environmental and Community Context

• The offshore oil and gas industry in Southern Louisiana, including the Black Bay area, has significantly impacted local communities and ecosystems. The industry has transformed hamlets and towns, and the platforms serve as habitats for fish and other sea life.
