Paper presented at the SPE Annual Technical Conference and Exhibition, October 26–29, 2020
Paper Number: SPE-204269-STU
... Abstract Chemical enhanced oil recovery (EOR) is a method that helps to increase recovery of oil in the tertiary stage of a reservoir. Methods such as polymer, surfactant, and microbial injection increase overall recovery by producing unswept or residual oil that remains after a water flood...

Paper Number: SPE-201308-MS
...-pack integrity by interlocking proppant grains in a flexible 3D network. The grains do not require temperature activation and so perform equally well at any temperature below 200°F, both in oil and gas reservoirs. The fibers can be applied with any proppant (sand or ceramic), and they keep the proppant...
