Polymer-EOR Worldwide Potential Contribution to Reducing CO2 Emissions
Authors J.L. Mogollon, E. Tillero and F. PerettiSummaryThe anthropogenic CO2 emissions and global warming pose a significant threat and challenge to the oil industry. Frequently, the industry claims that emissions in oil production are a lot less than in other segments of the chain value. While that may be true, it does not mean they are neglectable.
This paper proposes the generalizations and low, mid, and high scenarios needed to estimate the worldwide CO2 emissions due to aqueous flooding projects. The potential emission reduction if polymer flooding projects replace Waterflooding was calculated.
The mid scenario, 80% water cut, yielded the following results:
- Worldwide Waterflooding (WF) injection: 312.5 million barrels per day
- Worldwide CO2 emissions by WF projects: 0.24 million tons per day
- Replacing WF with polymer flooding reduces the emission by up to 64.5%
That confirms that CO2 emissions from Waterflooding are significant. Polymer flooding can reduce them by up to 80%, depending on the scenarios compared. It has the additional advantages of production acceleration and increased recovery with lower water production that must be treated and disposed of.

Petrophysical Changes due to CO₂ - Reservoir Rock Interaction – A Study Case
Authors F. Peretti, S. Gonzalez, J. Mogollon and E. TilleroSummaryThis article analyzes the alteration of petrophysical properties due to the rock-CO2 interaction in saturated Cretaceous sandstone with high geological CO2 content. It is based on the response of different physical principles tools and the data integrated into a workflow previously applied successfully in several mature fields. The knowledge generated sheds light on the causes of oil production of a sand reservoir falling rapidly, up to approximately 25% per month, from more than 1000 bbls/day initial rate.
Specifically, we analyze the impact of CO2 on the petrophysical properties of the rock by integrating X-Ray Diffraction, formation water composition, production history, decline index, stimulation results, Oddo-Thomson’s calcite saturation, and information from conventional and special logs in a typical well. This methodology can be easily adapted to other deposits with similar characteristics.
CO2 distorted the density logs and NMR logs readings. That causes porosity overestimation with the density logs and under-estimation with NMR logs. Therefore, this is an excellent indicator of CO2 presence in the pore space. To obtain the correct effective porosity, we used the density neutron logs.

Microfluidic Pore-scale Analysis of Polymer Flooding Effects of Polymer Molecular Weight and Viscosity
Authors Z. Qi, X. Fan, O. Serediak, A. Abedini, P. Ghosh and R. WiltonSummaryPolymer flooding is a widely applied EOR method to increase oil recovery from heavy oil reservoirs by improving the mobility and conformance control of the displacement process. Core and sandpack floodings have been mostly applied to evaluate the polymer flooding performance for a given reservoir; but the associated pore-scale dynamics with varying polymer MW and chemistry remains unclear in these experiments. Hence, a synergistic approach of coreflood testing along with visual experiments can provide the detailed insight of polymer flow behavior and performance. Microfluidic experiments through accurate representation of reservoir rock properties and several sequences of EOR fluid injections can bridge this gap. In this study, a microfluidic chip analogus to Bentheimer sandstone outcrop was designed for all the injection experiments. Single viscosity injection tests with 2 different polymer MW resulted in improved mobility control and faster and higher ultimate oil recovery with higher viscosity slug compared to lower viscosity. Sequential injection tests of low and high viscosity resulted in higher ultimate oil recovery with lower MW polymer due to improved sweep efficiency. Optical analysis suggested higher residual oil in porous media due to significant pore plugging and fingering behavior with the higher MW polymer compared to lower MW polymer.

How Chemical EOR Can Contribute to Reduce Carbon Footprint While Ensuring Stable and Affordable Energy Supplies?
Authors G. Dupuis and N. PhilipsSummaryToday the oil and gas sector faces a challenge to respond to the call for a transition to clean energy, Net Zero, whilst continuing to produce hydrocarbons to meet demand. Our global economy has a continued and growing dependence on hydrocarbons for existing energy systems and as a key feedstock for many of the products that we all use in everyday life. There is therefore the challenge: how to transition to a Net Zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth. Applying polymer EOR produced water volumes can be reduced significantly with associated reductions the energy associated with treatment and disposal.
The use of EOR polymers enable a reduction of CO2 emissions by around 50 to 70%. With produced water also being reduced by between 70% to 85%. Oil recovery is also accelerated by several years at a cost ranging between $3 and $6 making polymer flooding very attractive to both support operational.
