The Impact of the Fracturing Fluid Spontaneous Imbibition on the Petrophysical Properties of Low Permeability Reservoirs
Authors: Al-Ameri Aymen , Gamadi Talal , Watson Marshall 
Published: January 2018

Abstract
In the present study, spontaneous imbibition experiments, steady-state permeability measurements, and numerical simulation are integrated to quantify the changes in the effective water permeability, capillary pressure and water relative permeability curves due to the polymer adsorption of the spontaneously imbibed fracturing fluid. The effect of the surfactant and core bedding plane on the fluid spontaneous imbibition volumes were also investigated.
The researchers considered a spontaneous imbibition of a 0.1 wt% friction reducer fluid into low-permeability sand core samples extracted from Scioto, Crab Orchard, and Kentucky outcrops. Three comparative systematic spontaneous imbibition experiments were conducted for each of the core samples using distilled water, friction reducer fluid, and distilled water again. Prior to each experiment, the core sample was cleaned with toluene and then dried completely. The core sample water permeability before and after the imbibition experiment was measured using a constant rate steady-state permeability apparatus.
The results showed that the polymer adsorption throughout the fracturing fluid spontaneous imbibition significantly reduces the water spontaneous imbibition volumes. Moreover, the polymer adsorption effect increases as the porosity increases. The results showed also that the effective water permeability is decreased because of the polymer adsorption effect. The Residual Resistance Factors calculated from the spontaneous imbibition experiments are in agreement with the values calculated from the constant rate permeability measurements.
Adding surfactant to the pad stage- friction reducer fluid increases its spontaneously imbibed (leak-off) volumes. The results showed also that the effect of polymer adsorption on the imbibition rates is significantly less when the rock-fluid contact surface is parallel to the bedding plane.
The imbibition potentials were calculated before and after polymer adsorption. Since the water permeability was calculated independently, the capillary pressure curves were calculated from the imbibition potentials. The results showed polymer adsorption leads to a slight increase in the capillary pressure. The spontaneous imbibition experiment is numerically simulated using ECLIPSE commercial simulator and the imbibition water relative permeability curves were calculated by matching the results to the water spontaneous imbibition experimental data. The results showed that the polymer adsorption significantly reduces the water relative permeability curves for Scioto and Crab Orchard.

Published: January 2018

Background:We herein described a rare case of schwannoma of the hypoglossal nerve in the submandibular region with diagnostic imaging and histopathological findings.Case Report:A 31-years-old woman has had a palpable firm, rubbery, freely mobile mass in the submandibular region. Of imaging, MR images showed homogeneous isointensity on T1-weighted imaging (T1-WI), heterogeneous hypointensity on T2-WI, heterogeneous hyperintensity on short T1 inversion recovery (STIR), and heterogeneous enhancement on contrast-enhanced T1-WI. A clear capsule was observed on the margin and showed hypointense on T2-WI. Dynamic MRI showed heterogeneous gradual increased enhancement. The uptake of contrast medium was regionally slow. Diagnostic imaging using CT and MRI was suspected of salivary gland tumor or neurogenic tumor. In consideration of imaging diagnosis, a pleomorphic adenoma or a schwannoma was suspected. Final diagnosis was confirmed on the basis of histopathological finding and intraoperative findings.Conclusion:1. Histopathologic examination is inevitable, because MR findings are not specific.2. Schwannomas were said to have specific MRI properties, including specific signs (split-fat sign, fascicular sign, target sign). However, they are not always observed.3. This case confirmed the differential diagnosis on the basis of the intraoperative finding that the tumor was continuous with the hypoglossal nerve.

Published: January 2018

Background
Adolescents who self-harm are often unsure how or where to get help. We developed a Web-based personalized decision aid (DA) designed to support young people in decision making about seeking help for their self-harm.

Objective
The aim of this study was to evaluate the feasibility and acceptability of the DA intervention and the randomized controlled trial (RCT) in a school setting.

Methods
We conducted a two-group, single blind, randomized controlled feasibility trial in a school setting. Participants aged 12 to 18 years who reported self-harm in the past 12 months were randomized to either a Web-based DA or to general information about mood and feelings. Feasibility of recruitment, randomization, and follow-up rates were assessed, as was acceptability of the intervention and study procedures. Descriptive data were collected on outcome measures examining decision making and help-seeking behavior. Qualitative interviews were conducted with young people, parents or carers, and staff and subjected to thematic analysis to explore their views of the DA and study processes.

Results
Parental consent was a significant barrier to young people participating in the trial, with only 17.87% (208/1164) of parents or guardians who were contacted for consent responding to study invitations. Where parental consent was obtained, we were able to recruit 81.7% (170/208) of young people into the study. Of those young people screened, 13.5% (23/170) had self-harmed in the past year. Ten participants were randomized to receiving the DA, and 13 were randomized to the control group. Four-week follow-up assessments were completed with all participants. The DA had good acceptability, but qualitative interviews suggested that a DA that addressed broader mental health problems such as depression, anxiety, and self-harm may be more beneficial.

Conclusions
A broad-based mental health DA addressing a wide range of psychosocial problems may be useful for young people. The requirement for parental consent is a key barrier to intervention research on self-harm in the school setting. Adaptations to the research design and the intervention are needed before generalizable research about DAs can be successfully conducted in a school setting.

From various sources, we know that the science of spermatologii studied at various farm animals. The composition and properties of surface plasma membrane glycolipids determine mitotic phase cell activity and cell division. Demonstrated their exceptional role in cell-cell interactions: in the phenomena of «recognition» of cells to each other, adhesion, differentiation, growth, proliferation, contact inhibition of growth. In this article, we were examined lymph, lymph and blood composition, such as the volume of blood plasma in rams against the backdrop of one of the oldest forms of non-specific defense response – inflammation caused by surgical injury. Experiments were carried out on 14 rams Altai Merino. After a clinical examination of the animals, quickly create lymph venous anastomosis between the thoracic duct and jugular vein on the previously developed modifications N. Myrzakhanova, 1980. To prevent the lymph and blood clotting heparin was injected intravenously. A sample of the lymph and blood for analysis were taken from the thoracic duct and jugular vein. Elactica Kastrati morning before and after the conference. Analysis of morphological composition of blood and bodices, and total protein was carried out by conventional methods in hematology and hematocrit using microcapillary. Studies have shown thatafter elastica Kastrati observed very excited animal. There was an increase in heart rate of 66 to 81 beats per minute and respiration of 16 to 28 breaths per minute. Increased body temperature to the upper limit of normal (before 39.90) and inhibition of motor-evacuation activity of the rumen from 3.5 to 1.2 beats perminute. These changes most evident the first 1-2 hours (Р<0, 01-0,001), and then restored to the original values. Dynamics of white blood cells in the lymph and blood in this phase were determined not only the formation and release them in the lymph and circulatory changes depended on. This is evidenced by the decline in the value of lymph flow and hematocrit. Thus, reduction in the number of blood leukocytes Incoming defined reduction in lymph circulation on the one hand and an increase of the plasma volume with the other. Physiological assessment of the above leads to the conclusion that post-traumatic reaction at elastica Kastrati proceed fully and relatively easily transferred animals.

Published: January 2018

The most common malignancy of testis is seminoma with prognosis that is not always good because of high recurrence rate and death cases. Extracellular matrix metalloproteinase inducer (EMMPRIN) is a glycoprotein adhesion molecules which plays a role in tumor cell invasion and metastasis as evidenced by immunohistochemistry method in several types of tumor cells and tissue that shows the correlation to the clinical progessivity.This study was conducted by observational descriptive analytics with each seven cases of seminoma nonrecurrences and recurrences diagnosed histopathologically from Dr.Hasan Sadikin Hospital, Advent Hospital and St.Borromeus Hospital in Bandung. This study shows that immunoexpression of estrogen receptor beta is not higher in testicular seminoma recurrence compared with nonreccurence. There was no higher imunoexpression of EMMPRIN receptor on testicular seminoma recurrence compared with nonrecurrence; besides, there was no relationship between immunoexspression of estrogen receptor beta and EMMPRIN in testicular seminoma nonrecurrence and recurrence.In conclusion, immunoexpression estrogen receptor beta expressed in all testicular seminoma, so that the patient could be given an alternative therapy and immunoexspression EMMPRIN, cannot be used to predict a recurrence in patients with seminoma who has received complete therapy.
