... for an earthen embankment dam (IBCE, 1906). They also recommended that additional borings be undertaken at the dam site before finalizing its design, to ascertain the footprint of the filled paleo-channels. The original American scheme in 1903 for construction of a dam along the Chagres River...

... commenced in 2005 with high-angle appraisal wells designed to intersect fractures. These modern wells confirmed that the Clair Ridge area could be developed by up to 36 production wells drilled from a dedicated platform. Detailed planning of the early Clair Phase II production wells started in 2009. A more...

The reservoir sections would maximize connectivity between fault compartments and stratigraphic units, and positioning was optimized with well-site biostratigraphy. Each reservoir section exceeds 4000 ft and maintains at least 1000 ft vertical stand-off...
