Recovery-Impacting Petrophysical Alterations of CO2-EOR Application in Carbonate Formations: Case Study on North Dakota's Upper Red River
Authors: Abes Abdelmalek , Michael Andreas 
Published: April 2024

Abstract
Carbonate-based mineral dissolution and precipitation, driven by carbon dioxide (CO2) injection, introduces complexities into carbonate reservoir systems, triggering interactions that are different than those seen in traditional CO2 enhanced oil recovery (CO2-EOR) applications in siliciclastic/sandstone reservoirs. The thrust of this paper is to couple experimental (laboratory-scale) and numerical (computationally-assisted) analyses in order to assess how CO2-induced petrophysical alterations impact the resultant hydrocarbon recovery from CO2-EOR application in carbonate reservoirs.
The Upper Red River Formation, located in North Dakota's Cedar Creek Anticline (CCA) Field presents significant remaining oil-in-place, albeit a high-water saturation from waterflood operations undergoing since the 1960s. The residual (post-waterflooding), oil saturation, makes the Red River Formation a good target for modern-day CO2-EOR technology. The first part of this study involves a core-scale investigation of dynamic-permeability variations triggered by CO2 injection into three primary-productive zones, designated as "Red River Units" (RRU2, RRU4, and RRU6). The second part involves a compositional reservoir model built in SLB's Petrel software to perform numerical simulations of CO2 injection incorporating pre-established permeability variations that honor our laboratory-obtained results.
Correlations between differential-pressure variations observed during carbonated-brine (CO2/brine) injection were assessed against pore volumes injected (PVI). These pressure fluctuations were induced by dynamic-permeability variations resulting from carbonate-based mineral dissolutions/precipitations. Baseline-permeability variations were established a-priori using nitrogenated-brine (N2/brine) injection in order to correct for physico-chemical effects from the brine. During CO2/brine injection, the recorded permeability increased significantly compared to its original value, peaking before gradually recovering.
The history-matched compositional reservoir model was used to project the production from CO2-EOR through a section incorporating four existing wells, integrating laboratory-derived dynamic-permeability variations into the model, yielding different results due to incorporating laboratory-derived dynamic-permeability variations compared to simulations performed at constant permeability. Reduced reservoir permeability correlated with decreased oil recovery, emphasizing the significant impact of dynamic-permeability variations on CO2-EOR performance.
Carbonate Wettability Alteration: Core Flooding Test Under Reservoir Conditions with Carbonate Rock and Oil Samples from the Brazilian Pre-Salt

Abstract

HIGHLIGHTS
Evaluation of carbonates wettability modifier under Pre-Salt reservoir conditions.
Rock and oil originating from the Brazilian Pre-Salt.
Core flooding test under pre-salt reservoir conditions
Carbonates wettability modifier.
Surface agents can be used in different forms in upstream oil and gas production. One application is to enhance oil recovery by reducing interfacial tension (IFT) or changing the wettability of rocks from oil-wet (OW) to water-wet (WW). They can also be used for flow assurance purposes, preventing the deposition of inorganic scales. However, reducing IFT through surfactant application may lead to the formation of stable emulsions, complicating the separation of water from oil during primary processing. This study aims to evaluate the efficiency of a hydrotrope, specifically the phosphoric ester of glycerol (PEG-H), in increasing the hydrophilicity of carbonate petroleum reservoirs without significantly reducing IFT. The evaluation was conducted through a core flooding test to simulate pre-salt reservoir conditions, with a reservoir pressure of 6200 psi and a temperature of 84°C. The rocks and crude oil used in the test originated from the Brazilian pre-salt. The results demonstrate that the hydrotrope successfully enhances the hydrophilicity of carbonate rocks, resulting in an increased oil recovery factor, while maintaining a high IFT level.

Abstract
The active development of unconventional shale and tight reservoirs worldwide has helped unlock vast quantities of hydrocarbons in recent years. Hydraulic fracturing operations in horizontal wells is the most common method applied to unconventional reservoirs to unlock hydrocarbon resources by undergoing multiple fracturing stages. A common mixture of friction reducer, scale inhibitor, and other situational additives along with a carrier fluid, (brackish or recycled produced water) make up the completion or frac fluid. Often, the frac fluid is a colloidal suspension, as noted by the larger particle size distribution within the fluid. When exposed to reservoir conditions (elevated temperature, high formation brine salinity, high divalent ion concentration), frac fluids can destabilize due to the presence of polyacrylamide acting as a flocculant. Such behavior causes phase-separation and precipitation resulting in formation damage. Another scenario is the rapid production rate decline seen in hydraulically fractured horizontal wells. Typically, their production rates rapidly decline until stabilizing at a low terminal rate. Overcoming these trends to improve recovery is a major challenge. Fracture Fluid Chemistry Optimization (FFCO) technology development focuses on increasing recovery by designing and optimizing fracturing fluids for stimulation of shale formations. This stimulation fluid maintains clean fractures and penetrates deeper into the fracture network, mobilizing more hydrocarbons by altering rock wettability and lowering interfacial tension (IFT). The surfactants also alter the relative permeability to a more favorable state in the propped fractures. This work describes a workflow to optimize treatment fluids for injection into shale and tight rock reservoirs. The workflow incorporates rock and fluid property measurements and compatibility assessments between rock, reservoir fluids and frac fluids at the laboratory scale.
A Comprehensive Approach to Modelling Air Injection Based Enhanced Oil Recovery Processes

Published: April 2024

Abstract
Modelling of air-injection-based processes for enhanced oil recovery is a challenging task, mostly due to the complexity of the chemical reactions taking place. Also, the applicability of currently available kinetic models is limited to the reservoir systems they were originally developed for. The objective of this study is to derive a general chemical reaction framework that could be used to develop a kinetic model for a variety of crude oils (i.e., light or heavy oils).
The work is based on the modelling of high-pressure ramped temperature oxidation (HPRTO) experiments, and combustion tube (CT) tests, performed on three different oil systems: a volatile oil which is near critical at reservoir conditions (44°API), a low-shrinkage light oil (35°API), and a bitumen sample (10°API). A kinetic model was derived for each of the cases based on the history match of a HPRTO experiment. The resulting model was validated by history matching a CT test for each of the oils. An important feature of all these experiments is that they were performed at representative reservoir pressure conditions.
The modelling approach chosen is an extension of the methodology originally proposed by Belgrave et al. in 1993, which is arguably the most comprehensive kinetic model available in the air injection literature. However, their model was developed from experiments performed on Athabasca bitumen, and it fails to represent the air injection process as it occurs in light oil reservoirs encountered at high pressure. For example, Belgrave's model is based on the deposition and combustion of semi-solid residue commonly known as "coke", which is rarely present during the combustion of light oils at high pressure.
As in Belgrave's model, this study also describes the original oil in terms of maltenes and asphaltenes. The main difference lies on the presence and importance of oxygen-induced cracking reactions, as well as the combustion of a flammable mixture, which takes place in the gas phase. Also, a unique feature of these simulations is that, apart from history matching traditional variables such as thermocouple temperatures, fluid recovery and gas composition, they also capture changes in the physical properties of the produced oil, such as viscosity and density, which enhances the robustness of the approach and represents an important step towards the development of predictive simulation models.
This work is unique as it is the first time a single kinetic modelling approach is capable of modelling the in situ combustion of different oil types, which allows the consolidation of a general theory for air injection processes. Moreover, since the pseudo-components representing the fuel are not present in the original oil, the method is not limited to a fluid characterization in terms of maltenes and asphaltenes, but could potentially be applied along with any type of characterization of the original oil.
