Enhanced Recovery Technologies for Unconventional Oil Reservoirs

摘要

Unconventional resources have transformed the landscape of the oil and gas industry.The primary oil recovery factor ranges from 2-8% for the various shale plays throughout the US.Hence,it is imperative to develop the vast potential of unconventional reservoirs and increase the recovery factors beyond primary depletion by implementing IOR/ EOR methods.This article describes the role of effective reservoir management and summarizes the detailed review of the advances in IOR/EOR technologies applied to unconventional oil reservoirs,as performed by the Energy Industry Partnership Team(EIP)at the University of Houston(Balasubramanian et al.2018).That review included: 1.A thorough review of the pertinent published literature on IOR/EOR;2.Results of EOR application to unconventionals shared by various operators in their investor presentations and from press reports;3.Classifying IOR/EOR studies as laboratory experiments,numerical modeling,and field laboratory trials(pilots);4.Analysis of field trials based on the representative shale plays.
