Erosion by Proppant: A Comparison of the Erosivity of Sand and Ceramic Proppants During Slurry Injection and Flowback of Proppant

SPE Annual Technical Conference and Exhibition, 2004
Abstract During fracture stimulation treatments, particle-laden slurries may damage pumping equipment and have been shown to erode perforation tunnels. During subsequent flowback operations, minor to severe erosion of surface equipment may be observed if formation sand and/or proppants are produced.

Chemical Mitigation of Proppant Flowback

SPE International Conference & Exhibition on Formation Damage Control
Abstract Proppant production from hydraulically fractured shale wells has emerged as a significant source of revenue loss for operators utilizing artificial lift systems. The recent cost-driven adoption of lower-quality local sands has intensified this challenge, as these grains exhibit higher susceptibility to crushing, fines ...

Increased Resistance to Proppant Flowback by Adding Deformable Particles to Proppant Packs Tested in the Laboratory

Proceedings of SPE Annual Technical Conference and Exhibition, 1999
Abstract Numerous proppants, additives and remedial treatments now exist for the control of proppant flowback, yet it continues to be a problem in many oil and gas wells. These approaches to the problem can have certain merits but as a general rule they negatively impact production and are more costly than proppant alone.

Remediation of Proppant Flowback—Laboratory and Field Studies

Proceedings of European Formation Damage Conference, 2007
Abstract This paper presents the results of laboratory studies and field case histories of a remedial treatment technique using a low-viscosity consolidation fluid system that is placed into the propped fractures by coiled tubing (CT) or jointed pipe coupled with a pressure pulsing tool.

A Novel Slickwater System with Strong-Polarity Fibers for High-Efficiency Proppant Flowback Mitigation

Processes
To avoid or mitigate proppant flowback after a massive hydraulic fracturing of tight formations and to reduce its impairment to well productivity, this study developed a new type of fiber material with strong polarity based on polyester fiber. This fiber

Microscopic Mechanism of Fracturing Fluid Flowback Regulated by Coal Bridge-Proppant Wettability Contrast

Symmetry
Fracturing is a key technology for developing deep coalbed methane, in which the wettability contrast between proppants and coal bridges significantly influences flowback efficiency. This study integrates in situ wettability measurements with phase-field

Reducing Proppant Flowback From Fractures: Factors Affecting the Maximum Flowback Rate

SPE Hydraulic Fracturing Technology Conference, 2014
Abstract Proppant flowback under confining pressures is not well understood and difficult to reproduce in a laboratory setting. Improper management of proppant flowback leads to flow restrictions near the well bore, poor fracture conductivity and costly production equipment damage.

Proppant Flowback Prevention—A New Technology for Low BHST Applications

SPE Annual Technical Conference and Exhibition, 2005
Abstract A new phenolic resin system has been developed for proppant consolidation when fracturing low temperature wells. Before the development of this new resin system, which was in response to a global industry need, external chemical activators were necessary to achieve sufficient bond strength of the resin coated sand pack (when ...

Enhanced 2D Proppant Transport Simulation: The Key To Understanding Proppant Flowback and Post-Frac Productivity

Proceedings of SPE Annual Technical Conference and Exhibition, 1997
It has been assumed that along with fluid viscosity and pump rate, gravity dominates final proppant placement in hydraulic fractures. Results here, based on detailed multiphase-flow modeling, show that other factors such as slurry rheology (effect of adding proppant on slurry viscosity), fluid loss and layered fluid loss, and vertical fracture-width ...
