DESCRIPTION:Speakers: Tianyuan Zheng (Helmholtz Centre for Environmental R
esearch)\nCO$_2$ injection into a saline aquifer leads to a two-phase flow
system (supercritical CO$_2$ and brine)\, which often involves large spat
ial and temporal scales that require high computational cost. To address t
he computational challenge\, in the past decade\, a series of simplified m
odels based on vertical integration of the full multi-dimensional governin
g equations have been developed. These vertically integrated models either
assume a rapid segregation between CO$_2$ and brine due to strong buoyanc
y (i.e.\, vertical equilibrium assumption) or solve the one-dimensional ve
rtical two-phase flow dynamics as fine-scale problems on top of the (coars
e-scale) vertically integrated equations. The former is ofen referred to a
s vertical equilibrium (VE) model\, while the latter relaxes the VE assump
tion and is called dynamic reconstruction (DR) model [1\,2]. The major com
putational cost of the VE and DR models comes from solving the coarse-scal
e vertically integrated equations while the computation associated with th
e vertical reconstructions (either VE or DR) is minor. As such\, they are
much more computationally efficient than full multi-dimensional models and
have been used to answer many important engineering questions. However\,
the vertically integrated VE or DR models are often limited to aquifers wi
th homogeneous or layered heterogeneous properties. Thus\, for aquifers w
ith strong 3D heterogeneity\, the computationally expensive 3D models are
to date the only robust option. \nIn this talk\, we present a hybrid multi
layer framework to couple full multi-dimensional models with the various v
ertically integrated models. Such a framework allows us to use full multi-
dimensional models in highly heterogeneous layers of an aquifer where full
multi-dimensional model is the only robust option\, while applying simpli
fied vertically integrated models in layers with homogeneous or layered he
terogeneous properties. We develop algorithms to couple the full multi-dim
ensional model with vertically integrated models (VE or DR)\, as well as a
lgorithms for the coupling between the VE and DR models. In addition\, we
develop a local criterion to adaptively switch between VE and DR reconstru
ctors [3]\, i.e.\, use VE reconstructor when the two fluid phases are in e
quilibrium while use DR reconstructor to capture vertical dynamics when th
e fluids deviate from vertical equilibrium. Comparisons with full multi-di
mensional models (MRST [4] is used in our work) show that our adaptive hyb
rid multilayer model is much more computationally efficient than full mult
i-dimensional models while providing results with similar accurary\, makin
g this hybrid model an attractive tool for modeling of CO$_2$ injection an
d migration in highly heterogeneous saline aquifers.\n\nhttps://events.int

DESCRIPTION:Speakers: Quanlin ZHOU (Lawrence Berkeley National Laboratory)
\nThe injection and storage of supercritical CO2 (scCO2) have been conduct
ed in fractured sandstone reservoirs at In Salah\, Algeria and Snøhvit\,
Norway\, and planned in fractured sandstone\, carbonate\, and dolomite res
ervoirs at Longyearbyen\, Norway\, Hontomin\, Spain\, and Kevin Dome\, USA
\, respectively\, with matrix permeability varying from 0.01 to 60 md. For
densely fractured reservoirs with low matrix permeability (e.g.\, at Long
yearbyen\, Norway)\, injected scCO2 can dissolve into the resident brine a
t fracture-matrix interfaces and the dissolved CO2 (dsCO2) can diffuse int
o the rock matrix making solubility trapping the dominant trapping mechani
sm. For fractured reservoirs with intermediate matrix permeability (e.g.\,
at In Salah\, Algeria)\, the storage of scCO2 in the rock matrix dominate
s with strong fracture-matrix interactions observed through field monitori
ng at In Salah. We developed a comprehensive conceptual model for enhanced
CO2 storage to account for global migration of scCO2 in the fracture cont
inuum\, local storage of scCO2 and dsCO2 in the matrix continuum\, driving
forces for scCO2 invasion and dsCO2 diffusion from fractures\, and brine
outflow through connected matrix blocks. \n\nFor the dominant matrix scCO2
storage\, we developed high-resolution fracture-matrix models for individ
ual matrix blocks\, homogeneous columns of fractures and matrix blocks\, a
nd heterogeneous REVs consisting of multiple columns of matrix blocks with
varying flow properties and sizes. The multiscale modeling results show t
hat the equilibrium efficiency of local scCO2 storage strongly depends on
matrix entry capillary pressure\, matrix-matrix connectivity\, and reservo
ir thickness\, while dynamic efficiency and transfer function are also sen
sitive to fracture spacing and matrix flow properties. The transfer functi
ons calculated for various REVs were used along with reservoir-scale dynam
ics of scCO2 plume flow in fractures\, showing that the preferential migra
tion of scCO2 through fractures is coupled with bulk dsCO2 storage in the
rock matrix that in turn retards the scCO2 fracture plume. The bulk matrix
storage is mainly driven by buoyancy between fracture scCO2 and matrix br
ine and facilitated by matrix-matrix connectivity that allows displaced br
ine to outflow\, enabling the rock matrix to act like an open system. Conv
entional dual-continuum models cannot capture these processes because they
model isolated matrix blocks with no capillary continuity\, thereby under
estimating storage efficiency.\n\nFor the dominant matrix dsCO2 storage\,
we developed the unified-form equations of diffusive flux of dsCO2 into br
ine-bearing matrix blocks of varying shapes (i.e.\, spheres\, cylinders\,
slabs\, squares\, cubes\, rectangles\, and rectangular parallelepipeds) an
d sizes (Zhou et al.\, 2017a\, b). We then applied the flux equations to a
fractured reservoir with various scenarios of matrix blocks by assuming 1
-D and 2-D radial scCO2 flow in fractures and by using diffusion of dsCO2
from fracture-matrix interfaces into matrix blocks as the sink for scCO2 i
n fractures. For each scenario\, the dynamic dsCO2 plume with different ma
ss fraction was produced analytically\, showing that solubility trapping i
s significant in fractured reservoirs with low matrix permeability and sma
ll fracture spacing.\n\nhttps://events.interpore.org/event/2/contributions

DESCRIPTION:Speakers: Taehyung Park (Korea Advanced Institute of Science a
nd Technology (KAIST))\nInjection of carbon dioxide (CO2) into deep geolog
ic formations has been widely proposed as an effective way for the permane
nt storage of CO2. Modification of the interfacial properties of CO2 in mi
nerals by using surfactant has been proposed aiming on increasing the mobi
lity of CO2 through porous media. Surfactants are proven to effectively al
ter the interfacial tension and wettability in both CO2/water/mineral syst
em\, improving the displacement and sweep efficiencies of CO2 in porous me
dia. In the meantime\, biosurfactants have been drawing much attention as
an alternative to the chemical surfactants for their biodegradability\, ec
ological suitability and low toxicity. However\, the question as to the ex
tent of microbial alterations in fluid wettability and interfacial tension
under reservoir pressure and temperature conditions still warrants furthe
r investigation. Therefore\, this study investigated the role of lipopepti
de biosurfactant on wettability and interfacial tension alterations in a C
O2/brine/mineral system for different CO2 phases during the growth of ther
motolerant and barotolerant bacteria\, Bacillus subtilis\, and the product
ion of lipopeptide biosurfactant\, surfactin. Quartz\, mica and carbonate
substrates were selected and used as representative minerals. While monito
ring the changes in the interfacial tension and wettability with pH\, flui
d samples were acquired from the brine phase\, and the concentrations of g
lucose\, nitrate\, ammonium and surfactin in the acquired samples were qua
ntitatively assessed using various assays and spectroscopic methods. As a
result of surfactin production by B. subtilis\, we observed the reductions
in interfacial tension and increases in contact angle at all tested cases
. The concentration of surfactin and the rate of wettability alteration di
ffered with the experimental conditions. The modification of CO2 wettabili
ty was the greatest for liquid CO2 while the least of modification was obs
erved for gaseous CO2. The obtained results allow in-depth assessment of t
he feasibility of using biosurfactant-producing bacteria for effective geo
logic carbon storage practices.\n\nhttps://events.interpore.org/event/2/co

DESCRIPTION:Speakers: Ioannis Zacharoudiou (Imperial College London)\nInje
ction of CO2 deep underground into porous rocks\, such as saline aquifers\
, appears to be a promising tool for reducing CO2 emissions and the conseq
uent climate change. During this process CO2 displaces brine from individu
al pores and the sequence in which this happens determines the efficiency
with which the rock is filled with CO2 at the large scale. The aim of this
work is to better understand the impact of different flow regimes\, durin
g immiscible two-phase flow\, on the displacement and storage efficiency o
f CO2 deep in saline aquifers. Using multi-GPU free energy Lattice Boltzma
nn simulations we directly solve the hydrodynamic equations of motion on a
three dimensional geometry reconstructed from micro-CT images of Ketton l
imestone and consider fluid flows in a range of capillary numbers Ca and v
iscosity ratios. We first verify the existence of the three typical fluid
displacement patterns\, namely viscous fingering\, capillary fingering and
stable displacement [1]. We examine how these distinctively different flo
w regimes can affect the displacement efficiency\, defined here as the fra
ction of the defending wetting fluid that has been displaced from the pore
matrix when the injected non-wetting phase reached the outlet of the doma
in. Continuing the injection beyond this point we establish the maximum di
splacement efficiency or storage capacity. Our results indicate that the m
aximum displacement efficiency decreases with decreasing Ca. As capillary
fingering becomes the dominant displacement process at low Ca\, storage ef
ficiency converges to a limiting value irrespective of the viscosity ratio
. \n\nParticular focus is given to the low Ca flow regime\, where displace
ments at the pore scale typically happen by sudden jumps in the position o
f the interface between brine and CO2\, Haines jumps. We demonstrate that
the method reproduces the expected features of the jumps\, i.e. sharp incr
ease in the non-wetting phase velocity\, abrupt drop in the pressure signa
l and significant fluid rearrangement. We quantify the degree of fluid red
istribution associated with these sharp events by identifying each event f
rom the pressure signal. Preliminary results from this analysis suggest th
at pressure fluctuations and waiting times between the jumps follow an exp
onential distribution\, in agreement with theoretical predictions\, while
the same also applies for the event filling volumes probably due to the ex
tensive fluid redistribution. More importantly a significant decrease in s
torage efficiency is observed\, irrespective of the direction of the jump
relative to the overall flow direction\, contrary to the arguments by Yama
be et al. [2]. This is due to irreversible fluid rearrangement during Hain
es jumps that alters the displacement pathways and renders regions of the
porous rock inaccessible to the injected non-wetting fluid. This has impor
tant implications in the context of geological sequestration of CO2\, as H
aines jumps become a limiting factor in the storage process.\n\nhttps://ev

SUMMARY:The impact of heterogeneity on the flow and trapping of CO2 in tar

DESCRIPTION:Speakers: Samuel Jackson (Imperial College London)\nThe Bunter
sandstone formation in the Southern North Sea and the Captain sandstone f
ormation in the Northern North Sea represent two of the largest potential
CO$_2$ stores in the UK\, with estimated capacities of up to 14 Gt and 1.7
Gt respectively [1\, 2]. With current UK CO$_2$ emission totalling ~400 M
t/yr [3]\, the Bunter and Captain formations alone have the potential to s
tore UK emissions for many years.\n\nIn order to determine the long-term f
ate of the injected CO$_2$ in these systems\, accurate characterisation of
the multiphase flow behaviour and trapping is needed [4]. Conventionally\
, multiphase flow functions\, namely relative permeability\, capillary pre
ssure and trapping\, are derived from viscous limit core flood experiments
\, measured at high flow rates on subsurface rock cores preferentially sel
ected for homogeneity [5]\, and either used directly in field scale modell
ing or for further upscaling. \n\nHowever\, for modelling low potential fl
ows characteristic of buoyantly driven CO$_2$ plume migration\, it is impo
rtant to derive properties that capture the impacts of rock heterogeneity.
Sub-metre scale capillary pressure heterogeneities will control local flu
id distribution\, resulting in equivalent relative permeabilties which are
dependent on the flow direction\, rock heterogeneity\, and the capillary
number [6]. Modelling studies have estimated that this can have a signific
ant impact on plume migration and trapping from the mm-km scale [7\,8]. H
owever\, no experimental protocols have been developed to inform the model
s with appropriate properties measured on heterogeneous rock samples in th
e laboratory.\n\nTo address the impacts of small scale heterogeneity on la
rge scale flow and trapping of CO$_2$\, we present a combined experimental
and numerical study on rock cores from the Bunter and Captain sandstone f
ormations. We analyse 38 small rock cores covering the entire 100m interva
l of the Captain D reservoir unit in the Northern North Sea\, and a smalle
r selection of cores taken from the Bunter Sandstone in the Southern North
Sea. We use a recently developed characterisation approach [9] to create
a 3D numerical model of heterogeneous rock cores\, based on laboratory obs
ervations. We incorporate hysteresis into the characterisation by building
on the recent approach developed by [10]. Once characterised\, the numeri
cal cores can accurately predict equivalent relative permeabilties and tra
pping\, dependent on the capillary number and direction of fluid flow.\n
\nThe numerical models are then used to investigate multiphase flow hyster
esis and trapping across the range of conditions estimated to prevail in t
he CO$_2$ storage reservoirs. Under these conditions\, we systematically e
xplore the impact of hysteresis and heterogeneity on flow and trapping at
multiple scales. The migration of CO$_2$ may be significantly enhanced by
heterogeneity when flow can align with the direction of layers. This situa
tion may arise in gravity currents of plumes underneath a confining caproc
k layer. In contrast\, flow is impeded by heterogeneity when the dominant
direction crosses bedding layers\, as may occur in predominantly upward bu
oyantly driven migration. In this case\, the lowered mobility results in s
ignificant spreading of the plume and residual trapping is also enhanced.\

DESCRIPTION:Speakers: Yiheng Tao (Princeton University)\nInjection of CO2
into a saline aquifer leads to a two-phase flow system\, including a super
critical CO2 phase and a brine phase. Various modeling approaches\, includ
ing fully three-dimensional (3D) models and vertical-equilibrium (VE) mode
ls\, have been used to study the system in unfractured formations. Three-d
imensional models solve the governing flow equations in three spatial dime
nsions and are applicable to generic geological formations. VE models assu
me rapid and complete buoyant segregation of the two fluid phases\, result
ing in vertical pressure equilibrium and allowing integration of the gover
ning equations in the vertical dimension. This reduction in dimensionality
makes VE models computationally much more efficient\, but the associated
assumptions restrict the applicability of VE model to formations with mode
rate to high permeability. \n\nIn this presentation\, we extend the VE and
3D models to simulate CO2 injection in fractured aquifers. This is done i
n the context of dual-continuum modeling\, where the fractured formation i
s modeled as an overlap of two continuous domains\, one representing the f
ractures and the other representing the rock matrix. Both domains are trea
ted as porous media continua and\, as such\, can be modeled by either a VE
or a 3D formulation. The transfer of fluid mass between fractures and roc
k matrix is represented by a mass transfer function connecting the two dom
ains. Because the fracture domain is usually much more permeable than the
matrix domain\, we apply VE modeling to the fracture domain but not the ma
trix domain. We refer to the resulting model as a hybrid VE-3D model\, wi
th the VE model applied to the highly permeable fractures and the 3D model
in the less permeable rock matrix. \n\nOur hybrid VE-3D model includes bo
th dual-porosity and dual-permeability types. The dual-porosity model conc
eptualizes the rock matrix as sugar-cubes that are isolated uniformly by v
ertical and horizontal fractures\, or as match-sticks that are isolated by
vertical fractures through the entire thickness of the aquifer. In contra
st\, the dual-permeability model explicitly represents the 3D flow dynamic
s in the rock matrix. We derive mass transfer functions that couple the VE
model in the fracture to the different models in the rock matrix. We then
apply the hybrid VE-3D model to simulate CO2 migration in fractured salin
e aquifers and compare with 3D-3D models where both the fracture and rock
matrix are modeled in 3D. The hybrid VE-3D models are much more computatio
nally efficient while providing results that are close to those from the 3
D-3D models. These vertically-integrated dual-porosity and dual-permeabili
ty models provide a range of computationally efficient tools to model CO2
storage in fractured saline aquifers.\n\nhttps://events.interpore.org/even

DESCRIPTION:Speakers: Layachi Hadji (The University of Alabama)\nWe examin
e the linear and weakly nonlinear stability analyses of the dissolution-dr
iven convection induced by the sequestration of carbon dioxide in a geolog
ical formation. The mathematical model consists of Darcy's equation\, the
conservation of mass and the conservation of solute equations. The model a
ccounts for anisotropy in both carbon diffusion and permeability which is
modeled by a decaying exponential function of depth. The presence of a fir
st order reaction between the carbon-rich brine and host mineralogy is als
o included. We prescribe either Neumann or Dirichlet boundary condition fo
r the concentration of carbon dioxide at the rigid upper and lower walls t
hat bound a layer of infinite horizontal extent. We consider a Rayleigh-Ta
ylor-like base state consisting of a carbon-rich heavy layer overlying a c
arbon-free lighter layer and seek the critical thickness at which this con
figuration becomes unstable. With this approach\, standard mathematical me
thods that were successfully used in the study of Rayleigh-Benard convect
ion can be applied to this problem. We quantify the influence of carbon di
ffusion anisotropy\, permeability dependence on depth and the presence of
the chemical reaction on the threshold instability conditions and associat
ed flow patterns using the classical normal modes approach. The critical R
ayleigh number and corresponding wavenumber are found to be independent of
the depth of the formation. The weakly nonlinear analysis is performed us
ing long wavelength asymptotics\, the validity of which is limited to smal
l Damk\\"{o}hler numbers. We derive analytical expressions for the solute
flux at the interface\, the location of which corresponds to the minimum d
epth of the boundary layer at which instability sets in. We show that the
interface acts as a sink leading to the formation of a self-organized exch
ange between descending carbon-rich brine and ascending carbon free brine.
Plots of the high order perturbation terms for the concentration successf
ully reproduce the fingering pattern that is typically observed in experim
ents and full numerical simulations. Using the derived interface flux cond
itions\, we put forth differential equations for the time evolution of the
upward migration of the interface as the dissolution process progresses.
We solve for the terminal time when the interface reaches the top boundary
thereby quantifying the time it takes for an initial amount of injected s
uper-critical Carbon dioxide to be completely dissolved. We also consider
the case where the interface migration is accompanied by interface deforma
tions that conform to the convection pattern.\n\nhttps://events.interpore.

DESCRIPTION:Speakers: Amir Ghaderi (SINTEF Petroleum Research)\nUnderstand
ing the relation between CO2 saturation/distribution and velocity/attenuat
ion of acoustic wave propagation is fundamental for an accurate and reliab
le quantitative interpretation of (seismic) CO2 monitoring data.\n\nQuanti
tative interpretation of geophysical data requires understanding of the re
lationship between the physical properties of the rock\, the microstructur
e of the rock\, and the spatial distribution of the fluids saturating the
pore space. A large number of laboratory acoustic measurements on rocks ha
s been carried out in the past 10 years\, with indirect assessments of how
the saturation distribution is formed under in-situ conditions from ultra
sonic range (Mavko et al\, 1994) to seismic frequency scale (Tisato et al
.\, 2014). However\, there are almost no efforts towards quantitative meas
urements of how saturation distributions affect the acoustic measurements.
In particular\, no direct experimental link has been demonstrated between
the quantitative distributions of saturations at pore scale and the acous
tic properties of the saturated rock.\n\nThe relationship between elastic
wave velocities and fluid saturations (brine/CO2 and brine/oil/CO2 mixture
s) is strongly dependent on the spatial saturation distribution\, i.e.\, w
hether distribution is heterogeneous (patchy) or homogenous (uniform). The
saturation distribution in turn has a strong signature on attenuation and
dispersion of propagating waves\, even at seismic frequencies\, in the po
rous media due to wave-induced fluid flow mechanisms (Müller et al.\, 200
4 and 2010). Hence\, predicting saturation effects on the seismic response
requires a fundamental understanding of how attenuation and velocities ar
e affected by fluid distributions. Seismic quantitative interpretation of
CO2 monitoring data can be largely flawed if such mesoscopic phenomena are
not taken into account\, both for amplitude-based methods (due to attenua
tion) and waveform-based methods (due to attenuation and dispersion) (Dupu
y et al.\, 2017). The correct quantification of saturation and pore pressu
re levels require understanding the fluid distribution and physical proper
ties (Rubino et al.\, 2011).\n\nThe relationships mentioned above are diff
icult to predict and highly case-dependent. We present preliminary results
on a technique for establishing the relationships by core studies based o
n acoustic measurements in the ultrasound scale on CO2-brine saturated roc
ks. The experimental setup is simultaneously imaged in X-ray CT-scanner wh
ere the rock\, its microstructure\, and the fluid distribution at pore sca
le are visualized. This is a first step in the effort to study in laborat
ory the time resolved (4D) and spatial relationships between microstructur
es\, physical properties and saturation distribution of reservoir rocks ex
posed to CO2-bearing fluids.\n\nhttps://events.interpore.org/event/2/contr
