The main quarries are those of limestone used for cement production, and they are of multiphases and are well designed. Other quarries are randomly located without any scientific aspects; these are used for local purposes, mainly for aggregates. However, they are all polluting the environment (air, water, and soil) in different intensities and moods.</p> <p><strong>&nbsp;</strong></p> 2019-12-27T20:10:04+03:00 ##submission.copyrightStatement## Implementation of Hydraulic Fracturing Operation for a Reservoir in KRG 2020-02-10T12:56:56+03:00 Akram Humoodi Maha R. Hamoudi Rasan Sarbast <div> <p class="AbsKeyword">This study focuses on procedures to enhance permeability and flow rate for a low permeability formation by <a name="_Hlk27063699"></a>creating a conductive path using the hydraulic fracturing model. Well data are collected from the Qamchuqa KRG oil field formation. A Fracpro simulator is used <a name="_Hlk27063731"></a>for modelling the hydraulic fracturing process in an effective way. The study focuses on an effective hydraulic fracturing design procedure and the parameters affecting the fracture design. Optimum design of fracturing is achieved by selecting the proper fracturing fluid with a suitable proppant carried in a slurry, determining the formation fracturing pressure, selection of a fracture propagation fluid, and also a good proppant injection schedule, using a high pump rate and good viscosity. Permeability and conductivity are calculated before and after applying the hydraulic fracturing. Fracture height, length, and width are calculated from the Fracpro software, among other parameters, and the production rate changes. From the results, it is observed that by using hydraulic fracturing technology, production will increase and permeability will be much higher. The original formation permeability is 2.55 md, and after treatment, the average fracture conductivity has significantly increased to 1742.3 md-ft. The results showed that average fracture width is 0.187 inch. The proppant used in this treatment has a permeability of 122581 md. The suitable fluid choice is hyper with an apparent viscosity of 227.95 cp, and the proper proppant type is Brady sand with a conductivity of 2173.41 md-ft. Fracture orientation <a name="_Hlk27063957"></a>from the Khurmala oil field in Kurdistan is vertical fractures produced at a depth of 1868 m. Fracture half-length, total fracture height, and average fracture width are 220 ft, 42 ft, and 0.47 inch, respectively. After fracturing, the maximum and average area <a name="_Hlk27064009"></a>of fracture are 33.748 and 17.248 ft<sup>2</sup>, respectively. <a name="_Hlk27064021"></a>The recommended pump hydraulic horse power is 3200 HHP, and the total required fluid is 1076.3 bbl. In this study, hydraulic fracture is designed, and then, it has been analyzed after that production is optimized.</p> </div> 2019-12-27T18:53:41+03:00 ##submission.copyrightStatement## Bacteriological and Molecular Study Characterization of Klebsiella pneumoniae Isolated from Different Clinical Specimens 2019-12-27T20:12:39+03:00 Marwan Khalil Qader <p><em>Klebsiella pneumoniae</em> is one of&nbsp;the foremost&nbsp;imperative&nbsp;opportunistic&nbsp;pathogens.

Hamoudi Akram Humoodi Bashdar A. Mohammed <p class="Abstracttxt"><a name="_Hlk27047625"></a>Production logging tools (PLTs) in oil and gas industries are used for obtaining fluid types and measuring fluid rates in the borehole for both production and injection wells and to better understand the well productivity or the well injectivity of the interest zones. Additionally, it can be used to detect well problems, such as early water or gas breakthrough, channeling behind casing or tubing, and water or gas coning. The Khurmala field is a big oil field in the Kurdistan region of Iraq. <a name="_Hlk27048394"></a>PLTs have been acquired in many of the Khurmala oil wells, and the log records took into consideration <a name="_Hlk27048390"></a>the production technique decisions. In this study, results of the PLT log will be discussed in one of the Khurmala oil wells. Owing to the long history of production of oil or gas wells, many problems have been seen, such as coning either water or gas, formation damage, casing corrosion, and well obstruct. This research will evaluate the production profile across the slotted liner interval of (W1) well in the Khurmala oil field in the Iraq-Kurdistan region and detect possible water entry points, verify the distribution and nature of fluids, and estimate fluid segregation after the shut-in period. This was done by applying PLTs and interpreting the data by using Emeraude software.<a name="_Hlk27048514"></a>The performance of each choke size was studied and assessed. It was found that a choke size of 48/64̎gives the best favorable production gas, oil ratio, and profile. Results from the PL survey showed that no water entry was detected across the logged interval. All the water was coming from below a depth of 990 m; most of the hydrocarbons were coming from the slotted interval <a name="_Hlk27048683"></a>across 981.8-982.9 m, and the flowing pressure across the logged interval using maximum choke was less than the saturation pressure.</p> 2019-12-27T19:50:19+03:00 ##submission.copyrightStatement## Shanidar Cave: An Interesting Archeological Site in Iraqi Kurdistan Region 2020-02-14T16:01:02+03:00 Varoujan K. Sissakian <p>Shanidar Cave is one of the most well-known caves in Iraqi Kurdistan Region. It is an archaeological site located within Bradost Mountain north of Erbil city. Eleven skeletons of Neanderthals, have been found within the cave dating back to 65000 – 35000 years, they were called Shanidar (1 – 11).
