The oil industry has, in the last decade, seen successful applications of nanotechnology in completion systems, completion fluids, drilling fluids, and in improvements of well constructions, equipment, and procedures. However, very few full field applications of nano particles as an additive to injection fluids for enhanced oil recovery (EOR) have...
The stability of nanoparticles at reservoir conditions is a key for a successful application of nanofluids for any oilfield operations, e.g., enhanced oil recovery (EOR). It has, however, remained a challenge to stabilize nanoparticles under high salinity and high temperature conditions for longer duration (at least months). In this work, we report...
Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine are two crucial parameters regarding safety issues, as the timescale for dissolution corresponds to the same time over which th...
A simple and straightforward approach to synthesize oil-in-water (O/W) emulsions under high salinity and temperature using zwitterion functionalized latexes are presented in this work. First, well defined functionalized latexes were synthesized by emulsifier-free emulsion copolymerization in the presence of precursor sulfobetaine comonomer using br...
Altering the wetting state of a rock surface to more water-wet has been proposed as an enhanced oil recovery (EOR) mechanism for nanoparticles. However, how nanoparticles achieve this is not well understood. The objective of this study is to fill this knowledge gap by using advanced 2D and 3D visualization techniques.
In this study, advanced visual...
Wettability alteration is proposed as one of the enhanced oil recovery (EOR) mechanisms for nano particle fluid (nano fluid) flooding. The effect of nano particle adsorption on wettability alteration was investigated by wettability index measurement of Berea sandstone core injected with nano fluids and by contact angle measurement of a glass surfac...
Surfactant flooding process is one of the chemical methods widely used for enhanced oil recovery (EOR) from petroleum reservoirs that utilizes chemically synthesized surfatants. Such surfactants are not bio-degradable and hence pose environmental concerns. Because of stringent environmental restrictions, it is a high time for petroleum exploration...
To be effective enhanced oil recovery (EOR) agents, nanoparticles must be stable and transported through the reservoir. However, the stability of a nanoparticle suspension at reservoir salinity and temperature is still a challenge and how it is affected by reservoir rock and crude oil is not well understood. The objective of this study is to invest...
Oil and gas industry is witnessing a rapid increase of interest in application of nanotechnology. Since last few years, nanotechnology is being studied as an alternative enhanced oil recovery (EOR) method and laboratory experiments have shown its potential. However, the adsorption behavior of nanoparticles in porous media and underlying mechanisms...
CO2 dissolution is considered as one of the most promising mechanisms for trapping of free-phase CO2 into brine. It causes an increased density of the brine and initiation of gravitational instability that eventually leads to density-driven natural convection in saline aquifers. Correct estimation of the onset time for convection and the rate of di...
Integration of thermal systems improves the energy efficiency and reduces the carbon emissions. In this paper, a novel trigeneration system, which integrates the organic Rankine cycle and vapor compression–absorption cascade refrigeration cycle is proposed. The cascade refrigeration system combines the advantages of the conventional stand-alone vap...
Thermodynamic analysis of a micro-scale Organic Rankine Cycle (ORC) is performed, to assess its energetic and exergetic performances. The unique feature of the present study is that the performance of ORC is studied with modified Gouy–Stodola equation and the results are compared with the classical approach of exergy evaluation. The expressions are...
At Brahmakumaris (Shantivan Complex), Mt. Abu, Rajasthan an attempt is made to find possible applications of solar energy to construct the first 1 MW solar thermal power plant with thermal storage of 16 hrs. The plant is designed as a captive power plant (off grid) in co-generation to provide electricity and heat for the World Renewable Spiritual T...
This paper presents investigation on the relationship between rock wettability and oil recovery with low salinity water injection as secondary recovery process. Coreflooding experiments have been performed at room conditions on Berea cores with four different wettabilities ranging from water- to oil-wet. Brines and n-decane were used as displacing...
This paper presents the experimental and numerical simulation study of waterflooding of a very low permeability limestone outcrop. Continuous pressure measurements during waterflooding is carried out to estimate the permeability heterogeneity. Waterflooding experiments have been performed with vertical injection–vertical production (VI–VP) and vert...
This study presents an investigation on the effects of various polar components of a crude oil on its recovery by high and low salinity waterflooding and correspondingly on some of the suggested mechanisms in the literature. Coreflooding experiments were performed on several Berea core plugs aged in four different variants of the same crude oil wit...
Laboratory studies of low salinity waterflooding (LSW) have been performed to evaluate the potential of improved oil recovery at the Frøy field. Coreflooding experiments were conducted at high temperature and low pressure on reservoir core samples to determine the potential of LSW as an enhanced oil recovery (EOR) process for the field. Experiments...
This paper presents the changes in wetting conditions of Berea outcrops after low salinity waterfloodng (LSW) and its relation with the improved oil recovery. Coreflooding experiments were performed on neutral- and water-wet Berea core plugs of different permeabilities. Amott-Harvey test was used to characterize the wetting conditions of the core p...
The present work focuses on the effect of reservoir stratification (reservoir with layers of different permeability) on a water flood (immiscible displacement) process. Two-dimensional experiments have been performed on a visualization cell packed with sand particles of different sizes to form layers of different permeabilities. A total of four set...
Laboratory studies along with field tests conducted over the decade reveal that reducing the salinity of water injected into reservoirs improves the oil recovery. Different phenomena e.g. increase in pH (alkalinity), fines migration, multi-component ionic exchange, etc., have been proposed by researchers for improved oil recovery during low salinit...
Experimental and numerical study is conducted to investigate the performance of a horizontal well during waterflooding of a sandstone outcrop.

Dear Research community,
I am using a micro computed tomography (CT) for drug tablet quality check and quantification of some of its ingredients. The tablet contains some ingredients for which no reference gray values are available. In this case, what is the best way to quantify? Do I need to create references for respective constituents and determine the average grey values by performing scans with same scanning parameters that are used for tablet scan? Your suggestions/advise would be highly appreciated. Thanks.
I have aqueous suspension of salts with total TDS of ~ 38,000 ppm (NaCl + MgCl2 +CaCl2 + SrCl2), Silica nanoparticles (~2000 ppm) and polymer (~2000 ppm). I need to know the change in polymer concentration of such suspension after the process. Is there a reasonably accurate method to determine the polymer concentration in such aqueous suspension?
