There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection. Gas injection, which uses gases such as natural gas, nitrogen, or carbon dioxide (CO2), accounts for nearly 60 percent of EOR production in the United States. Thermal injection, which involves the introduction of heat, accounts for 40 percent of EOR production in the United States, with most of it occurring in California. Chemical injection, which can involve the use of long-chained molecules called polymers to increase the effectiveness of waterfloods, accounts for about one percent of EOR production in the United States. In 2013, a technique called Plasma-Pulse technology was introduced into the United States from Russia. This technique can result in another 50 percent of improvement in existing well production.

Enhanced Oil Recovery
It’s a process for recovering mostly every Barrels of Oil to get out all of remaining oil in it.
And this is done by EOR technologies
Enhanced Oil Recovery
Mainly the following process are done for Enhanced oil recovery
Water injection
Gas injection
Reducing residual oil saturation, SOR (alcohol, polymers, surfactants injection)
Thermal: steam injection (to heating of the reservoir to lower the viscosity)
The efficiency of enhanced oil recovery method is a measure of the ability to provide greater hydrocarbon recovery than by natural depletion, at an economically attractive production rate.

Modern oil and gas field management is increasingly reliant on detailed and precise 3D reservoir characterisation, and timely areal monitoring. Borehole seismic techniques bridge the gap between remote surface-seismic observations and downhole reservoir evaluation: Borehole seismic data provide intrinsically higher-resolution, higher-fidelity images than surface-seismic data in the vicinity of the wellbore, and unique access to properties of seismic wavefields to enhance surface-seismic imaging. With the advent of new, operationally-efficient very large wireline receiver arrays; fiber-optic recording using Distributed Acoustic Sensing (DAS); the crosswell seismic reflection technique, and advanced seismic imaging algorithms such as Reverse Time Migration, a new wave of borehole seismic technologies is revolutionizing 3D seismic reservoir characterization and on-demand reservoir surveillance. New borehole seismic technologies are providing deeper insights into static reservoir architecture and properties, and into dynamic reservoir performance for conventional water-flood production, EOR, and CO2 sequestration – in deepwater, unconventional, full-field, and low-footprint environments. This lecture will begin by illustrating the wide range of borehole seismic solutions for reservoir characterization and monitoring, using a diverse set of current- and recent case study examples – through which the audience will gain an understanding of the appropriate use of borehole seismic techniques for field development and management. The lecture will then focus on DAS, explaining how the technique works; its capability to deliver conventional borehole seismic solutions (with key advantages over geophones); then describing DAS’s dramatic impact on field monitoring applications and business-critical decisions. New and enhanced borehole seismic techniques – especially with DAS time-lapse monitoring – are ready to deliver critical reservoir management solutions for your fields.

Analysis of IFT (Interfacial Tension) and Viscosity of Various Polymer Based ...IRJESJOURNAL
Abstract: - The purpose of this experiment is to determine IFT and viscosity of various polymer based fluid in Enhanced Oil Recovery (EOR). Viscosity is a property of a liquid and it is defined as the resistance of a liquid to flow. Interfacial tension is the force that holds the surface of a particular phase together. Enhanced oil recovery (EOR) is the implementation of various techniques for increasing the amount of crude oil that can extracted from a well. One of the main techniques in EOR is by pushing crude oil by some fluids. Each fluid has different viscosity and IFT. A correct knowledge of IFT and viscosity of fluids using in EOR gives petroleum engineering tool of efficiently manage the production process of field. This study aimed to experimentally investigate the effect of different concentration Sodium hydroxide (NaOH), Potassium hydroxide (KOH) & Xanthangum on fluids using EOR. Four samples of fluids with different concentration of NaOH, KOH & Xanthangum which is mixed with water and carbonated water were used in this study.

Field Experience from a Biotechnology Approach to Water Flood ImprovementBill-NewAERO
Abstract
This paper is based on a field implementation in the United States of a biological process for improving waterflood performance. The Activated Environment for Recovery Optimization (“AERO™”) System is being developed by Glori in collaboration with Statoil and derives its roots from a microbial enhanced oil recovery technology developed and successfully implemented by Statoil offshore Norway. Unique among IOR technologies, AERO implementation requires virtually no capital investment and achieves high performance efficiencies at low operational cost. The simplicity of setup allows pilot project implementation creating a very low risk entry point for the operator.
A pilot project was selected for a controlled investigation of the performance and impact. Robust testing was done in both water and oil phases prior to treatment, confirming the potential for improved sweep and conformance from the project. Subsequent implementation resulted in decreased water cut and increased oil recovery observable both at the wellhead and allocated pilot levels.
This paper summarizes a rigorous analysis of the pilot project‟s performance to date, concluding that the production improvement should be credited to the implementation of the AERO™ System.
New AERO Technology (www.new-aero.com) is a green biotech company focusing on the recovery of oil more efficiently and effectively as well as wastewater treatment, contaminated soil/mud remediation and related data science. The AERO™ (Activated Environment for Recovery of Oil) technology was a recipient of 10 prestigious innovation awards since 2013. Earlier this year, the technology was named the top technology breakthroughs by CNPC and passed technical and projects evaluating phases for a $149 million US DOE LPO for Advanced Fossil Fuels.
The AERO™ is a low-cost, low-risk, easy to deploy bio-technology that builds on successful projects by Statoil and Glori Energy since the 1990s and has proven to be effective in enhancing the recovery of residual oil from active reservoirs that are undergoing waterflood in North Sea, USA, Canada and Brazil oilfields.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
