  • Prediction of Sand Product in the First Period of Production/Case Study of the Asmari Reservoir
    Jassim M. Al Said Naji, Ghassan H. Abdul-Majeed, Ali K. Alhuraishawy, Fadhil S. Kadhim, Ghazwan N. S. Jreou, Ali Al Mashat
    Petroleum Chemistry, 2024
    Abstract Sand production is a global issue that arises in fields that produce from sandstone reservoirs. Integrated sand production management needs sequential steps for optimizing and controlling process. The present paper is dealt with prediction of reservoir ability to produce sand at the first period of production and determine whether or not sand production control mechanisms are necessary. The constructed model was for Iraqi X4 well that produced from the Asmari reservoir in southern Iraq. Pore pressure measurements, reports, core test results, and well logs were the data used to perform the model. The Asmari reservoir was categorized into six layers (A, B1, B2, B3, B4, and C) based on the previous evaluation process. The X4 well was actually completed by sand screens down to the bottom hole before the well was opened to production. The methodology of the present paper was divided into three parts: To begin, the 1D mechanical earth model (MEM) is built by determining the principal stresses, pore pressure, elastic rock properties, and strength rock properties. Second, the outputs of (1D MEM) were used to compute the critical drawdown pressure (CDDP). According to the computed CDDP, four depths (3055, 3082, 3107, and 3133 meters) have the ability to produce sand at varying depilation rates (0, 15, 25, and 35%). The actual perforation interval of the X4 well existed within the same sanding likelihood interval. Finally, a single depth analysis was carried out for a depth of 3046.16 m. The result of single depth analysis plot was showed that there is no need to used sand screen at first period of production and well X4 can be producing until the pore pressure depletes to 2850 psi and bottom hole pressure to 1100 psi. The most essential feature of the offered results is the economic side, as sanding prevention tools and operations are expensive, thus employing them must be done after consulting with experts.
  • Estimating the Petrophysical Properties Cutoff Values for Net Pay Determination: A Case Study of Khasib Formation, Southern Iraq
    Alyaa M. Ali, Jassim M. Al-Said Naji, Mohammed A. Ahmed
    Petroleum Chemistry, 2024
    Abstract In order to calculate pay thickness and net/gross ratio, a set of limiting values (called cutoffs) for petrophysical parameters like permeability, shale volume, porosity, and water saturation should be defined. This paper thoroughly explains the most useful and applicable methods for calculating the cutoff values, outlining their advantages, disadvantages, and required input data. These techniques include the traditional Best fit line, Quadrant, Worthington, and Cumulative hydrocarbon methods. Khasib formation in Amara oil field is taken as a study object; the cutoff values are estimated according to the proposed methods. Considering the accuracy, the data available, and the limitations of each method. Khasib formation is divided into four units the reservoir units identified as KH2 and KH4, The cutoffs for the petrophysical properties were calculated for each reservoir unit. It was determined that the suitable cut-off value for permeability changes from one unit to another because of the different rock types that characterize each unit. The permeability cut-off for the KH2 unit is 0.01 and the estimated porosity cutoff value is 0.09. In contrast, for the KH4 unit, the permeability cut-off is taken as 0.1 and the porosity cutoff is estimated as 0.1. Furthermore, the calculated cutoffs of the shale volume and the water saturation are similar for the two reservoir units (KH2 and KH4) and equal to 10 and 60% respectively. Finally, the determined cutoffs can be applied and the net pay thickness and ratio of net/gross can be calculated for each unit in the objective formation.
  • Asphaltene Phase Behavior Modeling Using Peng-Robinson 78A-EOS for a Crude Oil Sample from Buzurgan Oil Field
    Mohammed A. Ahmed, Jassim M. Al-Said Naji, Alyaa M. Ali, Ali Qasim Al-Khafaje
    Petroleum Chemistry, 2024
    Abstract Asphaltenes are a solubility class that is thought to be the heaviest and polar component of the petroleum product. Asphaltene precipitation (AP) and deposition during oil production, processing, and transportation are key concerns for the oil industry. The current study analyzes the phase envelope of fluids and asphaltene precipitation of a real-live oil sample (bottom hole sample) from a well that was drilled in the Mishrif reservoir formation—Buzargan oil field in the Missan governorate in south-east Iraq. The study emphasizes a number of essential approaches for simulating asphaltene phase behavior using the Peng‒Robinson-78 advanced equation of state model for AP by using Multiflash software. The asphaltene precipitation envelope (APE) is the output of the equation of state, from which the authors may predict the operation conditions to avoid asphaltene precipitation. Prediction of these situations can improve reservoir performance and production systems ability to decrease asphaltene precipitation by regulating reservoir factors.
  • Prediction of Sonic Shear Wave Using Artificial Neural Network
    Jassim Naji, Ghassan Abdul-Majeed, Ali Alhuraishawy
    Iraqi Geological Journal, 2022
    Shear wave time is an important parameter participating in the calculation of rock mechanics properties. Many evaluation processes including wellbore stability analysis and sand production prediction are based on rock mechanics properties so these processes are directly related to the estimation of shear wave time. Several empirical correlations have been developed to predict shear wave time using regression analysis and artificial neural network techniques for the estimation of relationships between a dependent variable and one or more independent variables for certain conditions of the reservoir. However, they are not appropriate for reservoirs with different conditions as well as all effective parameters are not considered in previous relationships. In this study, the artificial neural network is adopted for predicting shear wave time using datasets consisting of 1922 data points for a certain directional oil well from Iraqi Fauqi oil field wells. Two sets of input parameters are tried: the first trial includes the readings of seven logs (Gamma-ray, caliper, compressional sonic wave, density, neutron, deep resistivity, true vertical depth), while the second trial includes the azimuth and the inclination angles in addition to the above seven readings. The optimum structure for both datasets is obtained using 12 neurons in a single hidden layer (ANN-7-12-1 and ANN-9-12-1). The statistical results reveal that an improvement is achieved when the well azimuth and inclination are included in the ANN model. A mathematical model with high performance using an artificial neural network has been developed. The mean square error and the determination coefficient for the developed model were 14.22 and 0.952 for ANN-7-12-1, while they were 9.62 and 0.966 for ANN-9-12-1, respectively. This study presents a simple mathematical model for further determination of shear wave velocities using ANN techniques which can be then integrated with the existent petroleum software programs.
  • Study of different geostatistical methods to model formation porosity (Cast study of Zubair formation in Luhais oil field)

    Iop Conference Series Materials Science and Engineering, 2019
    This study is concerned with making comparison in using different geostatistical methods for porosity distribution of upper shale member - Zubair formation in Luhais oil field which was chosen to study. Kriging, Gaussian random function simulation and sequential Gaussian simulation geostatistical methods were adopted in this study. After preparing all needed data which are contour map, well heads of 12 wells, well tops and porosity from CPI log. Petrel software 2009 was used for porosity distribution of mentioned formation in methods that are showed above. Comparisons were made among these three methods in order to choose the best one, the comparing criteria was according to different statistical information and variograms analysis of entered porosity which was scaled up and modeled. The best method gave porosity distribution in model closest to enter porosity that represent real porosity of Zubair formation. The comparison proved that sequential Gaussian simulation is the best model of porosity distribution followed by Gaussian random function simulation and kriging methods respectively. Based on the results obtained, it was concluded that the distribution accuracy of the porosity or other petrophysics properties is one of the main factors that affect building correct geological model that represents the base of reservoir model and also pore volume (Oil reserve) value was affected by geostatistical methods variation.
