Consortium Profile

HWCG LLC is a consortium of deepwater operators and non-operators in the Gulf of Mexico who have come together with the common goal of expanding capabilities to quickly and comprehensively respond to a subsea well containment event to protect people, property and the environment. 

HWCG is made up of a diverse and experienced group of deepwater operators and non-operators, representing two-thirds of the deepwater operators in the Gulf of Mexico.

Each HWCG member is committed to safe and responsible offshore drilling and prevention of a deepwater incident. 

As a member of HWCG, each company provides expertise and resources that collectively help achieve HWCG’s ultimate goal of rapid intervention, response and containment. 

Each company has made a financial investment to support the development of the group’s deepwater containment response system and committed to a mutual aid agreement, sharing assets and resources in the event of an incident.

What We've Achieved

These milestones represent a selection of our achievements:

  • First permit to resume deepwater drilling in the Gulf of Mexico after the Macondo well incident
  • First permit from a permanent facility
  • Full operability at depths of 10,000 feet
  • An expanded flow back capacity of 130,000 bfpd and 220 million cubic ft. of gas per day
  • Faster response times: deployed equipment and capped a test well in just six days, compared to the eighty-seven days needed to contain Macondo
