An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference)In this study, a new finite volume method is developed for shallow water equations on a rotating frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or numerical damping for ... -
Evaluating greywater and A/C condensate daily volume and water quality in urban settings
( American Society of Agricultural and Biological Engineers , 2011 , Conference)Due to increasing water demand as a result of population growth and improvement in living standards, many countries with arid climate are already facing water shortages that are being met by expensive desalination projects. ... -
Prediction of critical total drawdown in sand production from gas wells: Machine learning approach
( John Wiley and Sons Inc , 2023 , Article)Sand production is a critical issue in petroleum wells. The critical total drawdown (CTD) is an essential indicator of the onset of sand production. Although some models are available for CTD prediction, most of them are ... -
Iron Sulfide Scale Inhibition in Carbonate Reservoirs
( American Chemical Society , 2022 , Article)Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ... -
Applications of Machine Learning Methods to Predict Hole Cleaning in Horizontal and Highly Deviated Wells
( Society of Petroleum Engineers (SPE) , 2023 , Conference)Machine learning (ML) has become a robust method for modeling field operations based on measurements. For example, wellbore cleanout is a critical operation that needs to be optimized to enhance the removal of solids to ... -
Effect of Fluid Viscosity and Fiber Length on the Performance of Fibrous Fluid in Horizontal Well Cleanout
( Society of Petroleum Engineers (SPE) , 2023 , Article)During drilling, completion, and intervention operations, solids can deposit in the wellbore. Innovative cleanout fluids reduce the problems associated with inadequate hole cleaning. Various methods have been developed to ... -
Synthesis and performance evaluation of poly (acrylamide-co-malonic acid) as FeS scale inhibitor: experimental and theoretical investigations
( Institute for Ionics , 2023 , Article)This article reports on poly (acrylamide-co-malonic acid) and poly(AM-co-MAc) copolymers that inhibit the iron sulfide scale. The iron sulfide scale is considered as one of the most challenging oilfield scales to dissolve ... -
A robust Gaussian process regression-based model for the determination of static Young's modulus for sandstone rocks
( Springer Science and Business Media Deutschland GmbH , 2023 , Article)Static Young's modulus (Es) is one of the leading mechanical rock properties. The Es can be measured from experimental lab methods. However, these methods are costly, time-consuming, and challenging to collect samples. ... -
Hydrogen storage in gas reservoirs: A molecular modeling and experimental investigation
( Elsevier , 2023 , Article)Hydrogen is one of the clean energy sources that can be used instead of fossil fuel sources to reduce greenhouse emissions. However, hydrogen supply intermittency significantly reduces the deployment and reliability of ... -
Molecular simulations in upstream applications
( Elsevier , 2023 , Book chapter)The development of powerful computers and molecular simulation has allowed researchers to use them to get useful information about electronic properties related to chemical and physical interactions at the molecular level. ... -
A reservoir bubble point pressure prediction model using the Adaptive Neuro-Fuzzy Inference System (ANFIS) technique with trend analysis
( Public Library of Science , 2022 , Article)The bubble point pressure (Pb) could be obtained from pressure-volume-temperature (PVT) measurements; nonetheless, these measurements have drawbacks such as time, cost, and difficulties associated with conducting experiments ... -
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
( American Chemical Society , 2022 , Article)For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ... -
A sustainable approach to synthesize phosphonated chitosan using ball milling and its application for oilfield scale management

Fluid-rock interactions in tight gas reservoirs: Wettability, pore structural alteration, and associated multiphysics transport
( Elsevier , 2023 , Book chapter)Tight and unconventional reservoirs such as shales are rich in clay minerals that give rise to several fluid-rock interactions. The effect of such fluid-rock interactions is manifested at multiscales. The fluid-rock ... -
Introduction to reservoir fluids and rock properties
( Elsevier , 2023 , Book chapter)Hydrocarbon reservoirs contain gas, oil, water, and brine within the pores. The interactions between these fluids and the reservoir rocks have a considerable role in distributing the phases in the porous media. Understanding ... -
Rheology of upstream complex fluids
( Elsevier , 2023 , Book chapter)Rheology is an important characterizing technique as it affects all types of fluids. While oil and gas recovery is an operation that depends mainly on the interaction between different fluids, it is therefore important to ... -
