An Experimental Investigation of Immiscible CO2 Flooding Efficiency in Sandstone Reservoirs: Influence of Permeability Heterogeneity

Published: April 2018

Abstract
This paper presents the results of an experimental study on the effects of various CO2-injection modes on immiscible flooding performance in heterogeneous sandstone porous media.
Core flooding experiments were conducted for n-Decane – synthetic brine – CO2 systems at 9.6 MPa backpressure and 343 K to attain immiscible flooding condition (Minimum miscibility pressure (MMP) of CO2 in n-Decane is 12.4 MPa). For this purpose, two sets of heterogeneous sandstone core samples were assembled with heterogeneity in either parallel (layered samples) or perpendicular (composite samples) to the flow. The results obtained for both composite and layered core samples indicated that heterogeneity tremendously influences the outcome of the CO2 enhanced oil recovery (CO2–EOR). Oil recovery decreases dramatically with increase in the heterogeneity level or permeability ratio (PR). For instance, a recovery of 76.04% in a homogenous sample decreases to 72.15%, 65.97% and 54.71% when in layered samples the PR increases to 2.5, 5, and 12.5, respectively. In addition, the crossflow in layered core sample is found to have a noticeable effect on the ultimate oil recovery (increasing oil recovery up to 5%). It is also worth noting that for the composite samples when we arranged the plugs by putting the low permeability segments closer to the sample outlets the recovery factor increased (e.g. the recovery of 68.32% for Low-High-Low arrangement versus 64.37% for High-Low-High configuration). However, regardless of the segment arrangements, the recoveries in composite cores are less than that obtained from the homogeneous core sample (76.04%)).
Reservoir heterogeneity plays a critical role in determining the successes of the EOR processes, but its effect has rarely been comprehensively quantified in the laboratory. The limited experimental studies conducted to date seem to suffer from a number of deficiency mainly associated with sample preparation and experimental setup. In the present work, in addition to investigating a number of factors rarely studied experimentally before (e.g. effect of crossflow), attempts have been made to overcome the deficiencies of previous studies. Thus the results of this study can be insightful in overcoming the current challenges in capturing the importance of geological uncertainties in the current and future EOR projects.
MICP-Based Elastic Rock Typing Characterisation of Carbonate Reservoir

Published: April 2018

Abstract
A workflow applied to achieve a multi-scale characterisation of a carbonate reservoir is presented. Carbonate rocks are strongly heterogeneous due either to complexity of the primary fabric or to diagenetic over-printing. The combination of these features leads to complicated pore systems, thus a proper definition of pore types using either pore size or pore throat size distributions, is important to indirectly capture diagenetic modifications and to get a link to dynamic properties.
A new approach was developed in order to define a Rock Type classification (RRT) each time the approaches based on Winland's and Hydraulic Flow Unit methods do not give a reliable core facies characterisation when moving to the log scale. Moreover, the proposed workflow accounts for stratigraphy and seismic since RRT are linked to the elastic properties.
In the new MICP-based Rock Typing workflow, RRT are identified by describing dominant pore types using mercury injection (MICP) curves parameterisation and routine core data (RCA). Clustering and subsequent extrapolation of MICP derived RRT to RCA samples, are the first two stages to achieve a predictable classification into the log domain. Log RRT are then defined at the log scale using curves of elastic properties, like Poisson's Ratio (PR), Frame Stiffness (fk) and Flexibility (γk) Factors. These elastic parameters (calculated with the Extended Biot Theory), can capture the effects of pore structure on the petrophysical properties and link RRT prediction at well position to seismic attributes. Since the RRT are characterised in the elastic space, the facies model – properly upscaled – represents the basis to classify elastic attributes from seismic inversion in a Bayesian framework. The seismic classification can then be used as a driver for RRT distribution in the inter-well space into the 3D model. A further benefit is the direct relationship to the original RRT porosity/permeability distributions, when modelling petrophysical properties.
This new workflow was a successful solution to define homogeneous reservoir intervals in a carbonate environment characterised by the lack of a significant relationship between depositional facies and petrophysical properties.
Faecal contamination and visual clarity in New Zealand rivers: correlation of key variables affecting swimming suitability
Authors: Davies-Colley Rob , Valois Amanda , Milne Juliet 
Published: April 2018

Abstract
Swimming is a popular activity in Aotearoa-New Zealand (NZ). Two variables that strongly influence swimming suitability of waters are faecal contamination, as indicated by the bacterium Escherichia coli, and visual clarity as it affects aesthetics and safety with respect to submerged hazards. We show that E. coli and visual clarity are inversely related overall in NZ rivers (R = −0.54), and more strongly related in many individual rivers, while similar (but positive) correlations apply also to turbidity. This finding, apparently reflecting co-mobilisation of faecal contamination and fine sediment, suggests that visual clarity, measured or estimated from appearance of submerged features, should be a valuable indicator of faecal contamination status and (more generally) swimming suitability. If swimmers were to avoid river waters &lt;1.6 m black disc visibility (a long-established NZ guideline for swimming) they would also avoid microbial hazards (E. coli &lt;550 cfu/100 mL about 99% of the time in NZ rivers). However, urban-affected rivers might sometimes be microbially contaminated when still clear. Water management agencies should measure visual clarity together with E. coli in river surveillance. Real-time information on swimming suitability could then be based on continuous monitoring of turbidity locally calibrated to both visual clarity and E. coli.

Published: April 2018

BACKGROUND

Rheumatoid arthritis flares have a profound effect on patients, causing pain and disability. However, flares often occur between regularly scheduled health care provider visits and are, therefore, difficult to monitor and manage. We sought to develop a mobile phone app combined with a population management system to help track RA flares between visits.

OBJECTIVE

The objective of this study is to implement the mobile app plus the population management system to monitor rheumatoid arthritis disease activity between scheduled health care provider visits over a period of 6 months.

METHODS

This is a randomized controlled trial that lasts for 6 months for each participant. We aim to recruit 190 patients, randomized 50:50 to the intervention group versus the control group. The intervention group will be assigned the mobile app and be prompted to answer daily questionnaires sent to their mobile devices. Both groups will be assigned a population manager, who will communicate with the participants via telephone at 6 weeks and 18 weeks. The population manager will also communicate with the participants in the intervention group if their responses indicate a sustained increase in rheumatoid arthritis disease activity. To assess patient satisfaction, the primary outcomes will be scores on the Treatment Satisfaction Questionnaire for Medication as well as the Perceived Efficacy in Patient-Physician Interactions questionnaire at 6 months. To determine the effect of the mobile app on rheumatoid arthritis disease activity, the primary outcome will be the Clinical Disease Activity Index at 6 months.

RESULTS

The trial started in November 2016, and an estimated 2.5 years will be necessary to complete the study. Study results are expected to be published by the end of 2019.

CONCLUSIONS

The completion of this study will provide important data regarding the following: (1) the assessment of validated outcome measures to assess rheumatoid arthritis disease activity with a mobile app between routinely scheduled health care provider visits, (2) patient engagement in monitoring their condition, and (3) communication between patients and health care providers through the population management system.

Effects of milbemycin oxime, combined with spinosad, when administered orally to microfilaremic dogs infected with adult heartworms (Dirofilaria immitis)
Authors: Grant Tyre , Wiseman Scott , Snyder Daniel E. 
Published: April 2018

Abstract
OBJECTIVE To evaluate the safety of PO administration of a milbemycin oxime (MBO) and spinosad product to heartworm (Dirofilaria immitis)-positive microfilaremic dogs.
DESIGN Randomized, blinded, complete block trial.
ANIMALS 32 purebred Beagles with a patent heartworm infection.
PROCEDURES Dogs ranked by sex and microfilaria counts (range, 398 to 1,980 microfilaria/mL) were assigned to 4 groups of 8 to receive 3 treatments PO at 28-day intervals beginning on day 0: placebo (control group) or spinosad-MBO tablets containing MBO at the upper end of the label dose range (0.75 to 1 mg/kg [0.34 to 0.45 mg/lb]; 1× group) or 3 (3× group) or 5 (5× group) times that dose. Blood samples were collected at various points for adult heartworm antigen and Knott tests. Necropsies were performed on day 65, and recovered adult heartworms were counted.
RESULTS 1 control dog died from heartworm-associated complications. Other adverse events included mild, transient emesis (1 dog in each of the 1× and 5× groups and 3 dogs in the 3× group). Similar adult heartworm counts (range, 13 to 41) were obtained for all 4 groups. Results of blood antigen and microfilaria tests were positive throughout the study, with 1 exception in each of the 3× and 5× groups. Mean microfilaria counts increased with time in the control group, whereas reductions from baseline in treated groups ranged from 61.5% to 96.4%.
CONCLUSIONS AND CLINICAL RELEVANCE The evaluated MBO-spinosad formulation caused no severe adverse events when administered PO to microfilaremic dogs. Although microfilaria counts decreased following treatment, repeated monthly MBO treatments were incompletely microfilaricidal, suggesting MBO should not be used as a microfilaricide.

Abstract
OBJECTIVE To compare complications between healthy horses undergoing general anesthesia for ophthalmic versus non-ophthalmic procedures and identify potential risk factors for the development of complications.
DESIGN Retrospective case series.
ANIMALS 502 horses (556 anesthetic procedures).
PROCEDURES Medical records from January 2012 through December 2014 were reviewed to identify horses undergoing general anesthesia. Signalment, body weight, drugs administered, patient positioning, procedure type (ophthalmic, orthopedic, soft tissue, or diagnostic imaging), specific procedure, procedure time, anesthesia time, recovery time, recovery quality, and postoperative complications were recorded.
RESULTS Patients underwent general anesthesia for ophthalmic (n = 106), orthopedic (246), soft tissue (84), diagnostic imaging (110), or combined (10) procedures. Mean procedure, anesthesia, and recovery times were significantly longer for patients undergoing ophthalmic versus non-ophthalmic procedures. Excluding diagnostic imaging procedures, there was a significant positive correlation between surgery time and recovery time. Within ophthalmic procedures, surgery time, anesthesia time, and recovery time were significantly greater for penetrating keratoplasty versus other ophthalmic procedures. There was a significantly higher rate of postoperative colic following penetrating keratoplasty, compared with all other ophthalmic procedures.
CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that in healthy horses, duration of general anesthesia should be minimized to decrease the risk of postanesthetic complications. Judicious use of orally administered fluconazole is recommended for horses undergoing general anesthesia. For horses undergoing a retrobulbar nerve block during general anesthesia, use of the lowest effective volume is suggested.

The public open space in the city center is the identity of a city, which is a gathering place for the community for conducting activities, trading, celebrating, or just spending their spare time. Banda Aceh government has launched Aceh market area as one of historic area (heritage) as well as strategic area of Banda Aceh city. The purpose of this study is to identify factors that led to the transition of function and suitability of the arrangement of public open space facilities through Jhon Lang's theory of Urban Park Design Indicators and RTRW Banda Aceh City 2009-2029. The research methodology used is mixed methods with descriptive analysis. The result of the research shows that the arrangement of public open space facility in Pasar Aceh area has not been in accordance with Urban Design Indicator and RTRW Banda Aceh City 2009-2029. Those become the factor causing the shift of public open space function in Aceh market area. The lack of strict rules governing the parking of vehicles and street vendors also become factors causing the transition of public open space functions in the Aceh market area. Data obtained from the results of the study were analyzed by using SWOT. The SWOT analysis where obtained thre alternative strategy could be applied are : implementation of rules on arrangement and utilization of public open space in the Aceh Market area to be well ordered; implementation of rules with clear law enforcement will discipline street hawkers and motor vehicle owners who abuse public open space function in Aceh Market area; providing public open space supporting facilities and infrastructure in Aceh Market area in accordance with the theory of Urban Park Design Components and Indicators, RTRW Banda Aceh City 2009-2029.
