A supervised feed-forward back-propagation neural network model has been developed for estimating the recovery performance of a reservoir subjected to a surfactant–polymer (SP) flood. The optimal network paradigm has been designed by conducting extensive experimentation on the proper number of hidden layers, and of neurons in each of these layers. The optimal multi-layered network topology consists of an 18-neuron input layer, three 11-neuron hidden layers, and a four-neuron output layer. The network ...

The dependence of the shear wave velocity (Vs) of water-saturated reservoir rocks on petrophysical parameters was investigated. Two general regression neural network (GRNN) models were developed to predict Vs of sandstones, shaly sands, and carbonate rocks as a function of the compressional velocity (Vp), grain density (ρg), clay content, porosity (ϕ), permeability (k), and the cementation exponent (m) at a fixed effective stress and frequency. A set of 59 sample measurements of clean and dirty sandstones ...

Abstract The oil flow rate in a single vertical well undergoing gas lift operations is complicated by three factors: (1) The flow is driven by gas injection, in addition to the fluid flow potential gradient applied along the well, (2) the well is interfaced with a porous and permeable reservoir contributing with a fluid feed, and (3) the wellbore geometry may consist of concentric pipes of varying diameters and lengths, rather than a single-diameter pipe. Dimensional analysis is applied to this complex, ...

Low-salinity water (LSW) flooding is an emerging technique to enhance oil recovery from carbonate and sandstone reservoirs. Despite growing interest in the field, significant disparities remain regarding the underlying mechanisms. While most researchers agree that wettability alterations may be the dominant mechanism, their quantitative impact on oil recovery remains elusive. This study quantitatively evaluated the effects of LSW flooding on rock wettability alteration and oil recovery enhancement ...

The finite-control volume technique is used to solve the convection–dispersion equation in cylindrical coordinates. In the model presented, the dispersion coefficient is dependent on both velocity and diffusion coefficient. The solution allows analyzing the dispersion transport of a slug in a steady radial flow from an injection well fully penetrating a homogeneous reservoir of uniform thickness and finite drainage area. The solution is used to study the effects of a number of parameters, like dispersivity, ...

This study investigated experimentally the coupled effects of hydrophilic SiO2 nanoparticles (NPs) and low-salinity water (LSW) on the wettability of synthetic clay-free Berea sandstone. Capillary pressure, interfacial tension (IFT), contact angle, Zeta potential, and dynamic displacement measurements were performed at various NP mass fractions and brine salinities. The U.S. Bureau of Mines (USBM) index was used to quantify the wettability alteration. Furthermore, the NP stability and retention and ...

Predicting the flow zone indicator is essential for identifying the hydraulic flow units of hydrocarbon reservoirs. Delineation of hydraulic flow units is crucial for mapping petrophysical and rock mechanical properties. Precise prediction of the flow zone indicator (FZI) of carbonate rocks using well log measurements in un-cored intervals is still a daunting challenge for petrophysicists. This study presents a data mining methodology for predicting the rock FZI using NMR echo transforms, and conventional ...

Aims: The study's objective was to evaluate the canalis sinuosus (CS) anatomical structure in the front maxilla in order to prevent surgical problems in an adult Yemeni population sample acquired using cone-beam computed tomography (CBCT). Materials and Methods: A retrospective descriptive cross-sectional study was carried out to assess 226 participants' CBCT pictures. 452 sides in total were assessed. There were 140 females (61.9%) and 86 males (38.1%) among the samples. The age distribution was 18– ...

Background: Intermaxillary fixation is a technique that is used in the treatment of jaw fractures, orthognathic surgery, temporomandibular joint disorders, and occasionally morbid obesity. However, it disrupts normal nutrition, leading to weakened immunity, impaired healing, and higher complication risks, negatively impacting treatment outcomes and patient recovery. Thus, the aim of this study was to investigate the physiological changes in a sample of Yemeni patients following four weeks of IMF ...
