Modeling And Analysis Of Thermal Effects On A Fractured Wellbore During Lost Circulation And Wellbore Strengthening Processes, Ze Wang
LSU Master's Theses
To successfully prevent fracture propagation and combat lost circulation, a thorough understanding of the stress state in the near-wellbore region with fractures is imperative. One important factor that is not yet fully understood is how temperature variation during lost circulation affects pre-existing or newly initiated fractures. To address this problem, a 3D finite element analysis was conducted in this study to simulate the transport processes and state of stresses in the near-wellbore region during mud invasion into fractures. To take the thermal effects into account, a thermo-poro-elasticity model was coupled with flow and heat transfer processes. This study included a …
Reliability, Laying The Groundwork In Theory And In Practice, Nicholas Smith
Reliability, Laying The Groundwork In Theory And In Practice, Nicholas Smith
Graduate Theses & Non-Theses
Soils do not have specific properties like materials such as concrete and steel. The goal of this project is to measure these specific properties through field and laboratory tests-and to show how the information relates to engineering analysis and design.
Optimization Of Drilling And Blasting Practices At A Western Us Open Pit Copper Mine, Joel Gadikor
Optimization Of Drilling And Blasting Practices At A Western Us Open Pit Copper Mine, Joel Gadikor
Graduate Theses & Non-Theses
The mining process begins with drilling and blasting activities. The efficiency of blasting affects all downstream operations such as loading, hauling, crushing and milling. Therefore drilling and blasting activities should be designed to ensure that designed parameters produce the desired fragmentation. The Kuz-Ram model is a fragmentation prediction model and is widely used for predicting the fragmentation distribution from blasting in the mining industry. This research evaluates the performance of the Kuz-Ram and Modified Kuz-Ram models to determine the most accurate models applicable to a Western US open pit copper mine’s fragmentation data. The performance assessment was done using the …
Effect Of Pipe Rotation On Casing Pressure Within Mpd Applications, Zahrah Ahmed Al Marhoon
Effect Of Pipe Rotation On Casing Pressure Within Mpd Applications, Zahrah Ahmed Al Marhoon
LSU Master's Theses
Well control is one of the most crucial sectors in drilling engineering. Human lives and safety depend on the correct execution of the engineering design. Managed Pressure Drilling (MPD) is a new technology that has recently emerged in the oil and gas industry. It has special well control abilities supported by the RCD to continue drilling or carry operations that involve pipe rotation, while circulating out a gas kick. This thesis examines the effect of pipe rotation on casing pressure profiles within MPD kick circulation application. The analysis was carried on real scale kick experiments. These experiments were carried in …
