Modeling Hydraulic Fracturing Initiation And Propagation In Porous Rock Formationsl, Chang Huang
Modeling Hydraulic Fracturing Initiation And Propagation In Porous Rock Formationsl, Chang Huang
LSU Doctoral Dissertations
Hydraulic fracturing has long been introduced to the oil and gas industry since the early nineteenth century for both reservoir characterization and reservoir stimulation. Despite the progress made in the last two decades, many challenges still have not been tackled regarding not only the propagation problem but also the initiation problem due to its complexity. The dissertation is divided into two stages, i.e., before and after fracture initiation. The first stage of the research aimed at improving the accuracy in solving the poro-mechanical response of wellbore during fluid injection before a tensile fracture occurs, which is crucial to determine the …
Investigation Of Subsurface Stratigraphy And Groundwater Dynamics In The Mississippi River Delta, An Li
Investigation Of Subsurface Stratigraphy And Groundwater Dynamics In The Mississippi River Delta, An Li
LSU Doctoral Dissertations
The Mississippi River Delta (MRD) is socioeconomically important to the state of Louisiana and the United States. Various types of land-water system data have been collected in the MRD. However, very few efforts have been made to utilize these datasets in modeling regional stratigraphy and groundwater dynamics in the MRD, especially for the upper 50 m of the depth. In this interval of depth, the Mississippi River and surrounding interdistributary bays intensively interact with the groundwater system. The lack of knowledge in regional stratigraphy and groundwater dynamics hinder an understanding of how hydrogeological setting affects processes such as surface-groundwater interaction, …
