Weighted Least Squares Estimation of the Effect of Wastewater Pollution of Tigris River / Wasit Governorate
...Show More Authors

Abstract

The analysis of Least Squares: LS is often unsuccessful in the case of outliers ​​in the studied phenomena. OLS will lose their properties and then lose the property of Beast Linear Unbiased Estimator (BLUE), because of the Outliers have a bad effect on the phenomenon. To address this problem, new statistical methods have been developed so that they are not easily affected by outliers. These methods are characterized by robustness or (resistance). The Least Trimmed Squares: LTS method was therefore a good alternative to achieving more feasible results and optimization. However, it is possible to assume weights that take into consideration the location of the outliers ​​in the data and determine them accurately. In order to increase the Weighted Least Trimmed Squares: WLTS, the weight of the sample data on the estimation is repeated. In order to perform this research, the need for detection and investigation of the impact of pollution of the Tigris River in Wasit Governorate has been called for by wastewater, particularly Total Dissolved Solids: TDS as dependent variable, and the impact of three covariates Sulfates: SO4, Chloride: Cl and Phosphate: PO4 pollutants. The evaluation was done in in a precise manner and submitted to the competent authorities. In order to achieve this objective, a sample of (91) positions were drawn and checked in the laboratories of Wasit Governorate.

Heavy Metals Pollution in Soil and Its Influence in South of Iraq
...Show More Authors

The aim of this paper is to determine the significant levels of some heavy metals such: lead, chromium, nickel and cadmium, were determined. Sources of pollution and their distribution according to presence of elements in the soils over the whole zone of the province of Maysan in southern of Iraq were investigated 36 soil samples from different zones: residential, industrial, commercial, agricultural and main roads, were collected from the soil surface and a depth of 30 cm and analyzed measuring of concentrations for heavy metals by a device ICP-MS technique. The results were compared with global standard levels of these elements in the soil.

Incremental and acceleration production estimation and their effect on optimization of well infill locations in tight gas reservoirs
...Show More Authors
Abstract<p>The main role of infill drilling is either adding incremental reserves to the already existing one by intersecting newly undrained (virgin) regions or accelerating the production from currently depleted areas. Accelerating reserves from increasing drainage in tight formations can be beneficial considering the time value of money and the cost of additional wells. However, the maximum benefit can be realized when infill wells produce mostly incremental recoveries (recoveries from virgin formations). Therefore, the prediction of incremental and accelerated recovery is crucial in field development planning as it helps in the optimization of infill wells with the assurance of long-term economic sustainabi</p> ...
