The Mars B Development is by IPA definition an " Industrial Mega Project" that is within the execution phase. The development is focused on the addition of new infrastructure to the Mars Field located in the Mississippi Canyon protraction area of the Gulf of Mexico. The development operated by Shell (71.5%) with BP as a Working Interest Owner (28.5%) can be summarized into three major infrastructure components:The Olympus Tension Leg Platform (TLP)West Boreas/South Deimos Subsea Tie-backDedicated oil and gas export pipelines and the West Delta 143C Shallow Water Platform. The Mars B Development is a first for Shell in the deepwater GOM, in that it represents the first occasion that a second significant production and drilling facility (Olympus TLP) has been installed to complement existing infrastructure (Mars TLP). The Mars Field is a true deepwater giant with close to 4 billion boe hydrocarbons in place. The Mars TLP was brought on production in 1996 and to date (01.01.14) has produced over 700mln boe. The Mars TLP, a 24 well slot Tension Legged Platform with multiple subsea tie-backs, has a significant track record in developing the field. Constraints, such as the number of available well slots and capacity for future subsea tie-backs, limited its expansion. The structural limitation of the Mars TLP was a main driver for the need to install a second TLP, the Olympus TLP. Once the Olympus TLP is brought on production in 2014, the Mars Field Depletion plan can be characterized by the following numbers and the unique challenges of integrating the following:One Deepwater Giant Field50+ discrete Hydrocarbon reservoirsTwo Tension Legged Platforms48 Platform well bores + 6 subsea wellsField life extended to 2050(+) This presents the unique challenges of developing a holistic and evergreen Mars Field Depletion plan that captures the synergies provided by two production and drilling facilities on a single field; and further the ability to extend the Mars Field life to 2050(+) results in a depletion plan that will ensure that we maximize the recovery from a key GOM resource base.
