DRAINAGE BEHAVIOR OF AQUEOUS, POLYMERIC, AND OIL-BASED NITROGEN FOAMS: THEORETICAL AND EXPERIMENTAL INVESTIGATION
Govindu, Abhishek (2019-08-01)Foams can be formulated to have a wide range of densities and viscosities. This unique behavior makes foam suitable for underbalanced drilling where pressure exerted on formation is maintained below pore pressure and at ... -
Effect of fluid rheology and flow rate on wellbore cleanout operations in horizontal and deviated wells
Naik, Sarvesh (2015)Solids like milled plugs, produced sand or residual proppant are deposited in the wellbore during fracturing operation. These solids can impair hydrocarbon production or cause operational problems, and hence should be ... -
Effect of Oxygen Content on Soot Formation in a Co-Flow Diffusion Flame Fueled with Canola Methyl Ester and Diesel
Prado Carbonell, Stephanie (2021-05-14)The release of carbon particles (or soot; nanoscale sized carbon spheres) during a combustion process is the sign of hydrocarbon fuel not burning completely. The physical property (nano scaled) and chemical compounds ... -
Effects of Fuel Unsaturation on Pollutant Emissions from the Laminar Flames of Prevaporized Petroleum and Biodiesel Blends in Air
Balakrishnan, Arun (2017-05)Biodiesels, considered as alternative fuels to petroleum diesel, are defined as fatty acid methyl or ethyl esters derived from triglycerides of vegetable oils or animal fats. The utilization of biodiesels reduces greenhouse ... -
Evaluation of Turbulence Model Performance for Simulation of Low Prandtl Number Fluids in Nuclear Reactor Cooling Systems
Jock, William Daniel (2020)Nuclear energy is a promising alternative to fossil fuel energy sources. With advances to current cooling technology, nuclear energy can achieve more energy production and run more efficiently than earlier reactor designs. ... -
Experimental and numerical evaluation of shape memory polymer for lost circulation treatment in geothermal wells
Mohamed, Abdelmjeed (2022)Lost circulation presents formidable challenges to drilling operations, especially in high-temperature and fractured formations. Lost circulation events increase the nonproductive time (NPT) and the total cost of drilling ... -
