Abstract: Methods and apparatus for installing deepwater completions and performing well intervention from a vessel that can perform other duties while not running completions or performing interventions. The system for installing deepwater completions and performing well intervention may comprise a surface pipe handling and deployment package including a horizontally operated rig that may also be operated in a slanted mode. Deepwater completions may be deployed from the vessel via a buoyant horizontal riser (BHR), which may be supported by a submerged buoyant tensioning system (BTS). In this manner, the cost of performing completion or intervention operations may be significantly reduced compared to such operations run from a drilling rig.

Abstract: Disclosed and claimed herein are e,e,e malonic acid/acetic acid tri-adducts of buckminsterfullerene of the general formula C60R3, wherein each R is independently selected from groups of the formula ?CR1R2 wherein each R1 and R2 is independently selected from the group consisting of —H and —COOH, provided, however, that at least one of the R1's and R2's is a hydrogen. Processes for preparing and uses of the same for treating neuronal injury and for life-extension are also disclosed and claimed herein.
