Nanoparticle-stabilized microemulsions for enhanced oil recovery from heterogeneous rocks

Surfactant-stabilized microemulsions (MEs) are often used to reduce the capillary forces responsible for trapping residual oil inside rocks. Recent studies showed that the presence of nanoparticles (NPs) in ME could enhance oil recovery, however their interfacial interactions and the impact of rock characteristics is still unclear. The objective of this study was to understand the effect of microemulsions stabilized by nanoparticles (MENP) on pore-scale fluid displacement mechanisms in a heterogeneous rock such as Arkose. A novel method was developed to synthesize silicon oxide in-situ in a ME. These nanoparticles had less tendency to agglomerate compared to nanopowders and promoted the formation of Pickering emulsions. The impact of ME and MENP on oil displacement in Arkose was examined using microtomography integrated with miniature core flooding. Aged cores were subjected to flooding with different aqueous solutions to investigate the effectiveness of ME and MENP in enhancing oil recovery. We found that ME promoted oil mobilization by reducing IFT and enhancing emulsification. The ability of ME to solubilize adsorbed oil layers contributed to a wettability alteration from oil-wet to weakly water-wet. Therefore, ME could remove 20.0% of additional oil after waterflooding. The incremental oil removal with MENP compared to waterflooding (34.3%) was higher than that of ME due to the emulsification of oil into even smaller droplets where NPs and surfactants synergistically interacted at the interface. The small oil droplets could penetrate small capillary elements of the rock that were inaccessible to ME, leading to stronger wettability alteration especially in carbonate cement

Pore-scale dynamics of nanofluid-enhanced NAPL displacement in carbonate rock

This study presents a pore-scale investigation of two-phase flow dynamics during nanofluid flooding in subsurface formations containing non-aqueous phase liquids (NAPLs) such as crude oils. The goal was to gain fundamental understanding of the dominant displacement mechanisms of NAPL at different stages of nanofluid injection in a carbonate rock using x-ray microtomography integrated with a miniature core-flooding system. The nanofluid consisted of surfactant-based microemulsions with in-situ synthesized silica nanoparticles. After establishing its initial wettability state, the carbonate core sample was subjected to various pore volumes (PV) of nanofluid flooding (from 0.5 to 10) to examine the impact on NAPL flow dynamics. We found that most NAPL mobilization occurred within the first PV of injection, removing nearly 50% of NAPL from the rock. The nanofluid invaded into larger pores first due to a sharp decrease in NAPL/brine interfacial tension (from 14 to 0.5 mN/m) and contact angle (from 140 to 88°). With higher amount of nanofluid delivered into the pores through advection, over 90% of NAPL droplets were emulsified and their size decreased from 9 to 3 μm. Subsequent nanofluid injection could further remove NAPL from the smaller pores by altering the thickness of NAPL layers adsorbed on the rock. This dynamic solubilization process reached equilibrium after 5 PV of injection, leading to a reduced layer thickness (from 12 to 0.2 μm), a narrower in-situ contact angle distribution around 81°, and an additional 16% of NAPL removal

Pore-scale Modeling of Viscous Flow and Induced Forces in Dense Sphere Packings

We propose a method for effectively upscaling incompressible viscous flow in large random polydispersed sphere packings: the emphasis of this method is on the determination of the forces applied on the solid particles by the fluid. Pore bodies and their connections are defined locally through a regular Delaunay triangulation of the packings. Viscous flow equations are upscaled at the pore level, and approximated with a finite volume numerical scheme. We compare numerical simulations of the proposed method to detailed finite element (FEM) simulations of the Stokes equations for assemblies of 8 to 200 spheres. A good agreement is found both in terms of forces exerted on the solid particles and effective permeability coefficients

Altered RECQ Helicase Expression in Sporadic Primary Colorectal Cancers

AbstractDeregulation of DNA repair enzymes occurs in cancers and may create a susceptibility to chemotherapy. Expression levels of DNA repair enzymes have been shown to predict the responsiveness of cancers to certain chemotherapeutic agents. The RECQ helicases repair damaged DNA including damage caused by topoisomerase I inhibitors, such as irinotecan. Altered expression levels of these enzymes in colorectal cancer (CRC) may influence the response of the cancers to irinotecan. Thus, we assessed RECQ helicase (WRN, BLM, RECQL, RECQL4, and RECQL5) expression in primary CRCs, matched normal colon, and CRC cell lines. We found that BLM and RECQL4 mRNA levels are significantly increased in CRC (P = .0011 and P < .0001, respectively), whereas RECQL and RECQL5 are significantly decreased (P = .0103 and P = .0029, respectively). RECQ helicase expression patterns varied between specific molecular subtypes of CRCs. The mRNA and protein expression of the majority of the RECQ helicases was closely correlated, suggesting that altered mRNA expression is the predominant mechanism for deregulated RECQ helicase expression. Immunohistochemistry localized the RECQ helicases to the nucleus. RECQ helicase expression is altered in CRC, suggesting that RECQ helicase expression has potential to identify CRCs that are susceptible to specific chemotherapeutic agents

Study on biological status of the Gorgan Bay

Present study carried out between September 2011 and October 2012 in 19 sampling sites in order to investigate the trophy level, productivity, and natural dominant living conditions in the Gorgan Bay. According to the provided maps from the shoreline, depth, and sediment, the total area and volume of Gorgan Bay is 466 square meters and 905.33 million cubic meters respectively. Also the physic-chemical parameters including: water temperature, EC, salinity, transparency, DO, BOD_5, pH, Ammonia, Nitrate, Total hardness, Total alkalinity, and phosphate are determined and studies. 3 main phylum, 12 orders, 6 classes, and 12 families from bottom living organisms (macro-benthos) were identified in this region. Standard deviation in TSI was from minimum 37 in March up to maximum 65 in September and the annual average was 53. According to the average TSI in different months, for five months namely as March, April, June, August, and February the dominant situation was eutrophy. For the rest of months namely as May, September, October, November, December, and January the dominant situation was Meso-trophic in the Bay. Based on calculation, minimum and maximum productivity in the Bay were 92.26 and 700.66 Kg per hectare in October and July respectively. The annual average of productivity was 195.10 Kg per hectare

Different forms of informal coercion in psychiatry: a qualitative study.

OBJECTIVES: The objective of the study was to investigate how mental health professionals describe and reflect upon different forms of informal coercion. RESULTS: In a deductive qualitative content analysis of focus group interviews, several examples of persuasion, interpersonal leverage, inducements, and threats were found. Persuasion was sometimes described as being more like a negotiation. Some participants worried about that the use of interpersonal leverage and inducements risked to pass into blackmail in some situations. In a following inductive analysis, three more categories of informal coercion was found: cheating, using a disciplinary style and referring to rules and routines. Participants also described situations of coercion from other stakeholders: relatives and other authorities than psychiatry. The results indicate that informal coercion includes forms that are not obviously arranged in a hierarchy, and that its use is complex with a variety of pathways between different forms before treatment is accepted by the patient or compulsion is imposed

What is the potential for replacing monocultures with mixed-species stands to enhance ecosystem services in boreal forests in Fennoscandia?

The boreal forests of Fennoscandia are largely dominated by Norway spruce and Scots pine. Conifer monocultures have been favoured in forest management during the last decades. Recently, concern has risen that forests consisting of only one tree species could be vulnerable to biotic damage. Additionally, environmental and societal changes are placing new demands on forest utilization, thus shifting the focus to alternative forest management options providing a wider scale of ecosystem services. It has been proposed that mixed forests are better than monocultures with respect to biodiversity, risk management and recreational value. By synthesising research studies, we provide an overview of current knowledge on how to combine wood production and other ecosystem services in mixed boreal forests in Fennoscandia. We addressed the following questions in more detail: what are the effects of mixed forests on soil properties, understorey vegetation, biodiversity, wildlife, resistance to and resilience against damage, forest productivity and the multiple use of forests? Furthermore, what are the silvicultural possibilities for establishing and managing mixed forests?Based on this review, mixed forests appear to provide a higher output of most ecosystem goods and services, including higher biodiversity and improved risk management, soil properties and multiple-use values. The most serious challenge is the browsing by cervids, which damages sapling stands. There is potential to establish single-storied mixed forests with current regeneration methods and material. Further research is particularly needed on the silvicultural practices suited for mixed boreal forests
