Effect of well scheduling and pattern on project development management in unconventional tight gas reservoirs
...Show More Authors

The advancements in horizontal drilling combined with hydraulic fracturing have been historically proven as the most viable technologies in the exploitation of unconventional resources (e.g., shale and tight gas reservoirs). However, the number of fractures, well timing, and arrangement pattern can have a significant impact on the project economy. Therefore, such design and operating parameters need to be efficiently optimized for obtaining the best production performance from unconventional gas reservoirs. In this study, the process of selecting the optimal number of fractures was conducted on a section of a tight gas reservoir model (based on data from the Whicher Range (WR) tight gas field in Western Australia). Then, the optimal number of wells per that section was investigated using the net present value (NPV) economic indicator assuming that the production process in all wells starts at the same time (base case). After that, three drilling schedules and patterns namely infill, linear, and hybrid were studied to examine the effect of two timing scenarios known as a fixed point in time and percentage of cumulative production (including the 37.5% EUR (estimated ultimate recovery) and the 62.5% EUR). It was shown that base case and infill drilling have the highest NPV values followed by hybrid and linear patterns in all the timing scenarios. However, the base case and infill drilling scheduling were more sensitive to the development time than hybrid and linear patterns. Additionally, the optimal number of wells per section was found to be a clear function of drilling pattern and lease time. The optimal number of wells (assuming 20 years lease period) was higher in the base case and infill pattern compared to the hybrid and linear pattern. The current study aims to help operators understand how well scheduling and pattern can change the optimal number of wells and thus aid them to reach educated decisions regarding the optimal development plan for the section under the lease. This study can also help operators to develop their management plan by selecting the best drilling pattern and timing to ensure the best return on investment.

Numerical and Experimental Investigations of the Effect of PVD and Vacuum Pressure on the Degree of Saturation
...Show More Authors

    Soft clays are generally characterized by low shear strength, low permeability and high compressibility. An effective method to accelerate consolidation of such soils is to use vertical drains along with vacuum preloading to encourage radial flow of water.  In this research numerical modeling of prefabricated vertical drains with vacuum pressure was done to investigate the effect of using vertical drains together with vacuum pressure on the degree of saturation of fully and saturated-unsaturated soft soils.  Laboratory experiments were conducted by using a specially-designed large consolidometer cell where a central drain was installed and vacuum pressure was applied. All tests were conducted

Evaluation of the effect of local exogenous application of osteopontin on wound healing in rats
...Show More Authors

Background: Wound healing is a complex dynamical interaction between various cell types, the extracellular matrix, cytokines, and growth factors. osteoponetin is a substance that acts as an anti-inflammatory. Aims of study: The study was designed to identify the role of local exogenous applications of osteopontin on wound healing (in cheek skin). Materials and methods: Thirty adult male albino rats weighting an average of (250-300gm) used in this study, incisional wounds were made in the skin of the cheek of rat and they were divided into the following groups: A-Control group: 15 rats treated with 1µ l of normal saline B-Experimental groups: 15 rats treated with topical application of 1µl osteopontin. The scarification of animals we

Effect of non-thermal plasma by FE-DBD scheme on lipids in blood in vivo study
...Show More Authors

This study illustrates the impact of non-thermal plasma (Cold Atmospheric Plasma CAP) on the lipids blood, the study in vivo. The lipids are (cholesterol, HDL-Cholesterol, LDL-Cholesterol and triglyceride) are tested. (FE-DBD) scheme of probe diameter 4cm is used for this purpose, and the output voltage ranged from (0-20) kV with variable frequency (0-30) kHz. The effect of non-thermal atmospheric plasma on lipids were studied with different exposure durations (20,30) sec. As a result, the longer plasma exposure duration decreases more lipids in blood.

Toxoplasma gondii is a unique intracellular parasite, which infect a large proportion of the world population, but uncommonly causes clinically significant disease. The present study was performed to estimate the prevalence of toxoplasmosis in 400 apparently healthy blood donor males, their ages were between 18 and 57 years using enzyme linked immunosorbent assay, and to examine the effects of infection on total testosterone, free testosterone and follicle stimulating hormone (FSH) levels in their sera. Seroprevalence showed 10 (2.5 %) and 121 (30 %) of them had IgM and IgG antibodies respectively. Both acute and chronic toxoplasmosis in males recorded higher significant (P < 0.05) mean concentration for total and free testosterone hormone,
