Study of Conditions for Polyacrylamide Use in Petroleum Reservoirs: Physical Flow Simulation in Porous Media

Abstract

This article describes the reservoir's average shear rate calculation and the rheological study of the polymer dispersion under the target reservoir conditions. It also identifies and quantifies the rock-fluid interaction parameters with this reservoir, including the total adsorption, residual resistance factor. The results confirm that the selected polymer is suitable to the target reservoir.

Porous polymer oil sorbents based on PET fibers with crosslinked copolymer coatings

“…4 Such sorbents are typically made of polymers, while polymers also have other applications in the petroleum industry. [5][6][7][8] We have tested the capability to absorb petroleum as well as toluene; toluene has the advantage of being a good solvent for asphaltenes which are contained in crude oil. 9 These facts are the starting point for the present work, plus the nding of Kim and coworkers 10 that non-woven polyethylene terephthalate (NWPET) based sorbents might be useful for oil-spill recovery in marine environments, but only aer modication with hydrophobic polymers.…”

Avaliação de bancos de gradação viscosa na injeção de polímeros para a recuperação de óleo pesado

“…De acordo com Jennings (1971), o RRF ajuda a controlar a digitação entre a água e o banco polimérico causada pela diferença entre as mobilidades bem como pelas heterogeneidades presentes no reservatório. Além disso, Silva et al (2010) afirmam que o fator de resistência residual é mais frequentemente usado do que o fator de resistência em função das limitações operacionais para medir a permeabilidade ao polímero.…”
