Knowing the distribution of the mechanical rock properties and in-situ stresses for the field of interest is essential for many applications concerning reservoir geomechanics, including wellbore instability analysis, hydraulic fracturing, sand production, reservoir compaction, subsidence and water/gas injection throughout the filed life cycle. Determining the rock's mechanical properties is challenging because they cannot be directly measured at the borehole. The recovered carbonate core samples are limited and only provide discrete data for specific depths. This study focuses on creating a detailed 1D geomechanical model of the Mishrif reservoir in the Nasriyah oil field to identify the fault regime type for each unit in the formation. This is particularly important in CO2-EOR as it helps to understand reservoir connectivity and optimize CO2 injection. A geomechanical model is also necessary to evaluate the behavior of the reservoir and cap rock. This model can help predict the stress distribution, deformation, and potential failure zones. The Mishrif Formation has five units (from CI to MB-2). Based on the current results, the cap rock units (CI, CII) possess weak mechanical properties. The 1D mechanical earth model highlights different faulting regimes within the Mishrif Formation across various wells;as wells as, different trends of elasticand mechanical properties across the formation units. Some wells exhibit reverse (thrust) type faulting in the reservoir units and normal faulting in the barrier units. Conversely, other wells display strike-slip faulting in the reservoir units and reverse/thrust faulting in the barrier units. Also, the reservoir units exhibited it’s stiffness, brittle strength, it’s endurance to shear force and proved it’s geomechanical stability due to the high values of static young modulus, unconfined compressive strength, bulk modulus and relatively high mechanical properties it's important to note that the in-situ stress has significantly decreased in the barrier units.
Abstract
Bivariate time series modeling and forecasting have become a promising field of applied studies in recent times. For this purpose, the Linear Autoregressive Moving Average with exogenous variable ARMAX model is the most widely used technique over the past few years in modeling and forecasting this type of data. The most important assumptions of this model are linearity and homogenous for random error variance of the appropriate model. In practice, these two assumptions are often violated, so the Generalized Autoregressive Conditional Heteroscedasticity (ARCH) and (GARCH) with exogenous varia

The purpose of this paper is to use the dynamic approach in the deep learning neural network method, where in this method a dynamic neural network that suits the nature of discrete survival data and time varying effect. This neural network is based on the Levenberg-Marquardt (L-M) algorithm in training, and the method is called Proposed Dynamic Artificial Neural Network (PDANN). Then a comparison was made with another method that depends entirely on the Bayes methodology is called Maximum A Posterior (MAP) method. This method was carried out using numerical algorithms re

Six strengthened by NSM CFRP plates were presented to study the impact of several parameters on their structural behavior. The experimental results of four selected slabs under monotonic load, plus one slab under repeated load, were validated numerically. Then the numerical analysis was extended to different parameters investigation, such as the impact of added CFRP length on ultimate load capacity and load-deflection response and the impact of concrete compressive strength value on the structural performance of

The research was based on a main premise that apply the criteria of the Global Reporting Initiative (GRI) would provide useful information to users to help them make appropriate decisions. To achieve the goal of the research, the descriptive analysis method was used, and quantitative analysis was used. At the level of the descriptive analysis method, a desk survey was conducted. As for the quantitative analysis, it relied on applied data through a questionnaire form (Questioners) as a research tool, and the
