Analysis Of Refracturing Activities In The Major Shale Plays In The United States, Faisal Shammam

Masters Theses

"Refracturing of existing horizontal multistage wells has increased over the past decade in the oil industry. This work aims to investigate all the refracturing operations in the most active shale plays in the united states (Bakken, Niobrara, Marcellus, Permian, Eagle Ford, Barnett, and Haynesville) in terms of completion technique, candidate selection, treatment types, and refracturing production efficiency. To collect the data of the refractured wells, an advanced data analytics approach was applied to separate the refractured wells from 170,000 wells reported in FracFocus, a public chemical registry for hydraulic fracturing in the United States, and combine it with DrillingInfo database, …

Determination Of Significant Parameters That Drive Fracture Optimization In The Glauconite Formation, Southern Chile, Ghassan Saleh Mahdi Alqatrani

Masters Theses

"The Glauconite Formation in the Magallanes Basin of Southern Chile is a clay- and silica-rich formation with low permeability. As with many of the unconventional resources, the Glauconite Formation requires a hydraulic fracturing operation to enhance the productivity of the wells in this area.

Data and pertinent information of fracturing, completion, and reservoir quality parameters along with post-fracture production data were collected to initiate a database of nearly 70 wells, to be used to develop a better understanding of the fracturing behavior, optimize the well stimulation, and overcome the major barriers in the hydraulic fracturing of the Glauconite Formation. The …

Quantifying Ceramic Proppant Transport In Complex Fracture Networks, Vivekvardhan Reddy Kesireddy

Masters Theses

"Water fracs have become an essential part of unconventional reservoirs to create deeper fracture networks. Proppant transport in water fracs is challenging in terms of fluids ability to carry the proppant deeper into these fracture networks. This experimental study investigates the impact of the flow rates, fracture widths and complexity controlling the ability of proppant to flow into complex fracture networks. This research attempts to nullify the knowledge gap in understanding width heterogeneity in primary and secondary fractures. This study speaks for settling pattern and proppant transport through a slot flow model with a unique approach to understand stage wise …
