Blowout - Capping - Fracturing - Relief Well, A Full Cycle Workflow, Youssuf A. Elnoamany
LSU Master's Theses
Broaching is defined as the uncontrolled release of hydrocarbons to ocean seafloor after a loss of subsurface well control event. Failed attempts to cap the offshore wells undergoing worst case discharge may lead to hydraulic fracture initiation and subsequent propagation, leading to renewed release of hydrocarbon to the seafloor. During the capping stack shut-in process, pressure build-up will occur along the wellbore, exposing locations of possible fracture initiation to overpressurized fluid, such as directly below the casing shoe, and critical points along the well casing. Shall there be enough build-up pressure to exceed the minimum horizontal stress in an exposed …

Aggregation Of Uncontrolled Fluids During Catastrophic System Failures In Offshore Environments, James Thomas Stiernberg
LSU Master's Theses
Safety culture relating to offshore operations has shifted since the Deepwater Horizon blowout and resulting oil spill. This incident has prompted the research of high volume spills during all stages of hydrocarbon exploration and production. This study particularly covers the interactions of wells and offshore networks as they pertain to situations where a release of reservoir fluids to the environment is occurring. Primary concerns of this investigation are stream confluences, leak modeling, and fluid behavior; the first two will be handled with various numerical software packages (OLGA®, CFD, and nodal analyses) while the later will require more rigorous treatment and …
