Integrated Reservoir-Wellbore Nodal Analysis Workflow For Worst-Case Discharge Modeling, Florencia Anahi Vasquez Cordoba
Integrated Reservoir-Wellbore Nodal Analysis Workflow For Worst-Case Discharge Modeling, Florencia Anahi Vasquez Cordoba
LSU Master's Theses
According to the Bureau of Ocean Energy Management (BOEM), worst-case discharge (WCD) is the single highest possible daily flow rate of liquid hydrocarbon during an uncontrolled wellbore flow event [49]. The main objective of this research is to develop a workflow to calculate worst case discharge (WCD) volumes for a drilling scenario using an integrated reservoir-nodal analyses approach. Using robust integrated production modeling (IPM) tools, a nodal analysis workflow is developed to compute WCD volumes and rates that operators can use easily if they have IPM, or adapt to using a different software (including excel) in absence of IPM. A …
Two-Phase Flow Regime Map For Large Diameter Pipes And High-Velocity Flows, Matheus Sigaki Capovilla
Two-Phase Flow Regime Map For Large Diameter Pipes And High-Velocity Flows, Matheus Sigaki Capovilla
LSU Master's Theses
Worst-case-discharge (WCD) calculations are a pre-requisite for any new well to be drilled in the Gulf of Mexico (GoM). Models that were mostly developed for production rates prediction are currently used to calculate the WCD rate. These models were mostly developed for pipe diameters and flow velocities much smaller than those expected during WCD events. Therefore, these models may be miscalculating WCD rates.
This study aims at analyzing one of possible sources of errors in these models: the flow regime maps. The influence of diameter change on flow regimes is discussed. A thorough literature review is carried out for different …
