Subsea 7 has been awarded a contract by the Hess Corporation for installation work in support of the Stampede Project in deepwater US Gulf of Mexico.
The scope of work involves installation of flowlines, steel catenary risers, umbilicals, jumpers and associated subsea architecture which tie-back two drill centers to a tension leg platform (TLP) hosting drill centers, water injection and gas lifts.
Production will be via two 10in. flowlines from each drill centre. The main offshore installation phase is expected to commence in Q3 2016, concluding in Q1 2017.
Stampede, a joint development of the earlier Knotty Head and Pony discoveries, is located in Green Canyon Blocks 468, 511 and 512, approximately 220mi. southeast of New Orleans, Louisiana, in 3500ft of water, anStampede, a joint development of the earlier Knotty Head and Pony discoveries, is located in Green Canyon Blocks 468, 511 and 512, approximately 220mi. southeast of New Orleans, Louisiana, in 3500ft of water, and a reservoir depth of 30,000ft.
Hess says the plan initially calls for total of six production wells and four water injection wells from two subsea drill centers tied back to the TLP. A two-rig drilling program is planned with the first rig beginning operations 4Q 2015. First production is expected in 2018.
The deepwater subsea development will include gross topsides with the capacity to process about 80,000b/d and 100,000b/d of water injection capacity. Hess is estimating recoverable resources in the 300-350MMboe. Craig Broussard, Vice President - Gulf of Mexico, said: “We are delighted to have been awarded this important project from Hess Corporation for installation work in support of the Stampede Project. Having worked with Hess before in the Gulf of Mexico on the Tubular Bells construction scope, as well as on flexible product installation for Hess’ Ceiba Field in Equatorial Guinea, we are pleased to be continuing our work with this important client.”
