Title: QD2 in the III Tectonic Block of the Neft Dashlari Field Ways of Efficient Use of Residual Resources of the Usage Object Authors: Novruzov, Huseyn; Ahmadov, Elvin Abstract: Like many other oil and gas fields in Azerbaijan, as well as we have faced the problem of efficient development of residual resources at the QD2 production facility in the III tectonic block of the Oil Rocks field. The article explores ways to solve this problem. The proposal is to increase the number of production wells and apply new methods to increase oil production. Using the field classification model, it was proposed to apply a physical and chemical method in accordance with the geological and technological parameters of the QD2 production facility in tectonic block III. The efficiency to be obtained after the application of the method has been calculated.

Title: Brain Tumor Area Segmentation of MRI Images Authors: Kalejahi, Behnam Kiani Abstract: Accurate and timely detection of the brain tumor area has a great impact on the choice of treatment, its success rate, and following the disease process during treatment. The existing algorithms for brain tumor diagnosis have problems in terms of good performance on various brain images with different qualities, low sensitivity of the results to the parameters introduced in the algorithm, and also reliable diagnosis of tumors in the early stages of formation. In this study, a two-stage segmentation method for accurate detection of the tumor area in magnetic resonance imaging of the brain is presented. In the first stage, after performing the necessary preprocessing on the image, the location of the tumor is located using a threshold-based segmentation method, and in the second stage, it is used as an indicator in a pond segmentation method based on the marker used. Placed. Given that in the first stage there is not much emphasis on accurate detection of the tumor area, the selection of threshold values over a large range of values will not affect the final results. In the second stage, the use of the marker-based pond segmentation method will lead to accurate detection of the tumor area. The results of the implementations show that the proposed method for accurate detection of the tumor area in a large range of changes in input parameters has the same and accurate results.

Title: Comparative Analysis of Effectiveness in the Implementation of Natural Drive and Artificial Lift Methods for Hydrocarbon Production Authors: Muzaffarov, Samir; Ahmadov, Elvin Abstract: There are different production techniques that can be applied to produce hydrocarbons from subsurface formations. Reservoir fluids can be lifted to surface by either means of natural energy available within the reservoir or by applying artificial lift methods. Even though hydrocarbons are generally produced by natural drive mechanisms at the initial stage of field development where reservoir pressures are strong enough to push hydrocarbons to surface and then suitable artificial lifting techniques are implemented when wells cannot flow naturally, artificial lifting can also be applied to maximize production rate when individual well production rate is low due to lower reservoir pressure available in the system. The main objective of this research is to do comparative analysis of effectiveness in implementation of natural drive and artificial lift methods (gas – lift and pumps) for hydrocarbon production acceleration and optimization in West Absheron oil field, which is in the Caspian Sea, by using PROSPER software package based on a fictitious well data, namely Well WA-1. The Nodal Analysis is done for natural drive case and artificial lift techniques, specifically said, electrical submersible pump method and continuous gas lifting on PROSPER. Calculated oil production rates for natural drive, ESP and continuous gas lift cases are equal to 17.6 sm3/day, 53.8 sm3/day and 50.8 sm3/day respectively. Comparative analysis of the outputs obtained from this research show that implementation of artificial lift methods significantly increases oil production rate. However, considering that source for lift gas is the main challenge for gas lift application in West Absheron oilfield, it is concluded that ESP implementation in West Absheron oilfield wells is the most favorable choice.
