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.

RADON GAS AND EFFECTIVE DOSE IN GROUNDWATER IN ABU- JIR VILLAGE IN ANBAR, WESTERN IRAQ
...Show More Authors

In the present study, radon gas concentration in the shallow groundwater samples of the Abu-Jir region in Anbar governorate was measured by using Rad-7 detector. The highest radon gas level in the samples is up to 9.3 Bq/L, while the lowest level is 2.1 Bq/L, with an average of 6.44±1.8 Bq/L. The annual effective dose is varied from 33.945 μSv/y to 7.66 μSv/y, with an average of 0.145±0.06 μSv/y. Consequently, the radon level in the groundwater studied is lower than the standard recommended value (11 Bq/L) reported by the United States Environmental Protection Agency (USEPA). The potential source of radon is uranium-rich hydrocarbons that are leakage to the surface along the Abu-Jir Fault. This research did not indicate any ris

The effects of bisphosphonate administration on teeth development and growth of the jaw bones in neonatal rats (histological and immunohistochemical study)
...Show More Authors

Background: Bisphosphonates are potent inhibitors of osteoclastic bone resorption and widely used for the treatment of osteoporosis, and osteogenesis imperfecta in children. Clinical and experimental studies have demonstrated that Bisphosphonates delay or inhibit tooth eruption. This study tries to focus on the effect of bisphosphonate on teeth development and jaw bones growth. Materials and methods: The present study includes 65 neonatal rats during lactation period from 15 Albino Wister rats mother. Alendronate (one type of Bisphosphonates) was administrated orally (15 mg/kg) into 10 pregnant rats two times a week, while other 5 rats regard as control. Then the neonatal rats sacrificed in I, 6, 11, 16 and 21 days. The lower first molar we

Performance of Gas Induction in a Dual – Impeller Agitated Bioreactor
...Show More Authors

The rate of gas induction was measured in gas-inducing type mechanically agitated contactors provided with two impellers. A reactor of 0.5 m i.d. was used with a working capacity of 60 liters of liquid. Tap water was used as the liquid phase, and air was used as the gas phase. The bioreactor mixing system consists of two equal diameter stirrers; the top impeller is shrouded-disk/curved-blade turbine with six evacuated bending blades, while the bottom impeller was disk turbine. The impeller speed was varied in the range of 50 to 800 rpm. The ratio of impeller diameter to tank diameter (D/T) and the submergence (S) of upper impeller from the top were varied. The effects of clearance of lower impeller from the tank bottom (C2) an

  • The problem of infertility considers one of the chronic problem a which faced the
    individual & families equally . This problem causes a negative effects in psychological ,
    social and development fields. The infertility contributes in weakening the human
    development, when the human development has become as a centre point which centered
    about individual preparing , rehabilitation, training and knowledge toreach to the required
    excellence.
    We think that , the infertility destroys the socially development; therefore the socially and
    scientific institutions are working hard to find successful solution to resolve the problem

Some gas sensing properties of PbS thin films
...Show More Authors

In this research PbS thin film have been prepared by chemical bath deposition technique (CBD).The PbS film with thickness of (1-1.5)μm was thermally treated at temperature of 100°C for 4 hours. Some Structural characteristics was studied by using X-ray diffraction (XRD)and optical microscope photograph some of chemical gas sensing measurements were carried out ,it shown that the sensitivity of (CO2) gas depend on the grain Size and deposition substrate. The grain size of PbS film deposited on on glass closed to 21.4 nm while 37.97nm for Si substrate. The result of current-voltage characterization shwon the sensitivity of prepared film deposited on Si better than film on glass.

Research summary

 


Westernization is a term not familiar to our scholars at the beginning of the emergence of translation from Western literature, sciences and arts in its detailed form now.

Westernization was not an issue that those Greeks, Persians, Romans, Indians and others worked on translating those sciences and cultures. Rather, it was a process of transferring a new philosophy and logic that had not been previously seen by the Arabs, so they were affected by it in a strange way, to the point of fascination by some of them. For this reason, this research came to clarify these issues and address them within the scientific methodology.
