... fluids. In shales, uncrosslinked polyacrylamides (PAs) at low gel concentrations (0.5-2.0 gpt) have become the dominant fluid because of their lower cost, greater friction reduction, and higher retained conductivity. The use of these fluids is commonly regarded to be limited to unconventional formations...

... Abstract Fracture conductivity is a measure of the success of completion designs and subsurface fracturing treatments from fractured well performance. Conductivity can be evaluated from experimental investigation. Traditionally, samples for conductivity experiments involve fracturing downhole...

Abstract This paper presents a semi-analytical wellbore heat flow model coupled with a formation heat conduction model for rapidly determining output potentials of thermal energy from the open-loop and closed-loop geothermal systems. Energy conservation equations are used to simulate thermal...

... Abstract Good inter-well connectivity and high fracture network conductivity are crucial to the success of any enhanced geothermal system. Distributed fiber optic data from a geothermal fluid circulation test provides a direct measure of hydraulic connectivity of the wells through hydraulic...

... Abstract HF-based matrix acid treatments are beneficial in removing fines damage in sandstone formations and restoring productivity. In a proppant-fractured formation, fines dissolution/formation stimulation and proppant embedment/conductivity reduction can become competing factors after multi...
