Improving Polymer Flooding Efficiency in Oman Oil Fields0 Downloads2016. SPE179834  This study demonstrates the viability of a cost-effective alternative to what is already used in the Marmul field. This new polymer can be an appropriate candidate to keep chemical EOR in Omani southern fields economically viable.  Download Now!

Novel Associative Acrylamide-based Polymers for Proppant Transport in Hydraulic Fracturing Fluids0 Downloads2013. SPE164072 The properties of novel polymers for proppant transport in hydraulic fracturing operations are discussed. Acrylamide based associative polymers have been synthesized using various industrial production processes. Anionic polymers investigated are acrylamide (AMD) based co- and ter-polymers functionalized with monomers such as sodium

First successful Surfactant-Polymer injection in Hungarian Algyo oilfield0 Downloads2016. EAGE IOR. A long but rewarding R&D work has helped successfully deliver a new surfactant formulation which, along with a stable polymer, has been injected into a preselected part of the Algyő field, yielding outstanding results in terms of extra oil recovery. All the aspects have

Advanced Selection of Polymers for EOR Considering Shear and Hardness Tolerance Properties0 Downloads2016. EAGE IOR.  Polymer flooding has proven to be an effective technique to improve oil recovery from mature reservoirs. The selection of polymer, focusing mainly on its temperature tolerance properties and its ability to propagate in porous media, is key to achieve a

Rheological properties of stimuli-responsive polymers to improve salinity and temperature performances0 Downloads2015. SPE174618. This paper describes a new class of polymers, called “stimuli-responsive”, which has been designed to overcome the aforementioned challenges. This new family of polyacrylamide-based polymers has structurally modified to counterbalance the negative effect of salinity and temperature encountered during the transit through

Inline viscosity monitoring of polymer solutions injected in CEOR processes2 Downloads2013. SPE165249. Bonnier et al. This paper presents recent developments of in-line viscometer which can measure the viscosity at low shear as per real reservoir conditions. OpenSize: 1 MB

Polymer Retention Determination in Porous Media for Polymer Flooding in Unconsolidated Reservoir0 Downloads2021. Polymer flooding is a well-established technique aimed at improved recovery factors from oilfields. Among the important parameters affecting the feasibility of a large deployment, polymer retention is one of the most critical since it directly impacts the oil bank delay and therefore

Design, Characterization and Implementation of Emulsion-based Polyacrylamides for Chemical Enhanced Oil Recovery0 Downloads2016. EAGE IOR. As of today, the vast majority of chemical enhanced oil recovery projects have been conducted using polymers in powder form. The fact that many of these projects – not to say all – have been implemented onshore is probably part

Revisiting polymer selection workflows for chemical enhanced oil recovery5 Downloads2023. EAGE IOR+ The Hague. The workflow used to select and study polymer candidates for polymer flooding has remained relatively unchanged since the first projects were performed in the 1960s. Starting with viscosity curves and filtration test, the polymer candidates are then injected into cores representative

Spreadsheet – shear calculations for vertical perforated wells13 DownloadsThis Excel spreadsheet can be used to understand how shear rates vary in perforated vertical wells. This should help design the perfect completion to minimise mechanical degradation and avoid studying some parameters such as shear-thickening. Download spreadsheet
