An Experimental Investigation of Feasibility of Gas Huff and Puff for Recovering Crude Oil with Different Viscosities

Investigating multi cyclic gas (N2 and CO2) huff and puff have been conducted by long sandpack simulations with four different crude oils from Jiangsu oilfield. According to the production differential pressure and the production regularity during huff and puff, the production process was divided into three sections; the first one is free gas production section; the second section is low viscou...

3d Analysis of Huff and Puff and Injection Tests in Geothermal Reservoirs

Heat extraction from deep, hot rocks for energy production is based on water circulation through a man made fracture or natural fractures. As multiple and non-planar fractures in a stress field affect the geothermal reservoir behavior, so the capability to simulate multiple fractures and joints is needed to help reservoir design and operation. A 3D model is developed in this work to simulate an...

Integrating Embedded Discrete Fracture and Dual-Porosity, Dual-Permeability Methods to Simulate Fluid Flow in Shale Oil Reservoirs

Abstract: The oil recovery factor from shale oil remains low, about 5 to 7% of the oil in place. How to increase oil recovery from shale oil reservoirs is attracting more and more attention. CO2 huff-and-puff was historically considered one of the best approaches to improve the oil rate. Most previous simulation studies have been based on dual porosity, but simulation results from dual-porosity...

Using Huff n’ Puff with a Recycled Hydrocarbon Gas as a Means for Enhancing Oil Recovery in a Liquid-Rich Shale Reservoir APPROVED BY SUPERVISING COMMITTEE:

Vocalization During Huff

Only one healthy volunteer reported feeling no nasal discomfort while inhaling dry oxygen; all the other subjects reported some degree of discomfort and irritation. These data clearly demonstrate that humidification of oxygen reduces nasal discomfort that can occur in both young healthy volunteers and older patients with pulmonary disease, particularly at flows 3 L/min. Two limitations of this ...
