Asphaltene deposition in a reservoir severely reduces the effective permeability and results reduction oil production. The main term asphaltene modeling porous media is pore surface deposition. Previous models do not describe effects of different parameters (i.e., concentration, velocity, temperature) on term. We report series experiments carried out to study above using an accurate thermal method. Based these data, new expression for has been developed implemented modeling. model was used...

Geochemical parameters are useful properties to enhance hydrocarbon exploration certainty. Though, attaining these parameters, for instance total organic carbon (TOC), volatile and residual (S1 & S2) is a challenge geologists due the high cost time consumption. Therefore, addressing this issue has become an interesting subject many researchers. As result, on ground of conventional well logs, vast kinds methods, example, back propagation artificial neural network (BPANN), have been introduced...

Abstract Silica nanoparticles (SiO 2 NPs) have garnered substantial attention as versatile additives in saline fluids, finding application areas like environmental remediation, wastewater treatment, enhanced oil recovery, and carbon geo-sequestration. Despite their potential, the intricate interaction between electrolyzed porous media remains inadequately researched these contexts. This study delves into pivotal yet underexplored aspect of silica nanoparticle absorption behavior within...

Asphaltene precipitation and deposition is one of the main problems in some oil fields. The deposited asphaltene results partial or total blockage wellstring reducing completely seizing production. have been experienced field for a long time. Although, has studied thoroughly different parameters that effects this process investigated but little work carried out across production system flowing well. This paper introduces new comprehensive model description behavior wellstring. mechanisms...

With the advancement of technology, gas shales have become one most prominent energy sources all over world. Therefore, estimating amount adsorbed in shale resources is necessary for technical and economic foresight production operations. This paper presents a novel machine learning method called grey wolf optimizer support vector (GWO-SVM) to predict gas. For this purpose, data set containing temperature, pressure, total organic carbon (TOC), humidity has been collected from several...

Smart water (SW) has been recognized as an effective yet environmentally friendly technique for enhanced oil recovery in both carbonate and sandstone reservoirs. However, owing to complexities of properties, rock compositions, ion characteristics, the performance smart is not well-understood. This paper attempts derive insights on how performs clay-rich sandstones. A comprehensive mechanistic study carried out synthetic sandpacks that contain different clay types (kaolinite montmorillonite)...

Asphaltene destabilization is still known as one of the main problems petroleum industry and imposes many costs on this during crude oil production, transportation, refining. The most important solution to control problem using chemical compounds disperse asphaltene aggregates. Ionic liquids, an emerging industrial solvent catalyst, have been used for purpose in last two decades. In work, three ionic liquids having a tetrabutylammonium cation oleate, stearate, cinnamate anions were...

Abstract Determining the rate of asphaltene particle growth is one main problems in modeling precipitation and deposition. In this paper, kinetics aggregation under different precipitant concentrations have been studied. The image processing method was performed on digital photographs that were taken by a microscope as function time to determine mechanisms. results MATLAB software revealed aggregates strongly time. Different regions could be recognized during including reaction-...

Abstract Excess water production is one of the challenges that can cause several operational and economic problems. In this work, a comprehensive study PPG swelling in presence monovalent divalent ions was conducted. Then, practical mathematical modified fractal grow (MFG) model calculate amount different salinities overtime introduced. The output compared with experimental data showed matching about 80%. viscosity PPGs at various shear rates studied matched cross-viscosity model. To assess...

Abstract Formation damage is a general term, which refers to any process that reduces the production or injectivity of an oil well. Clay swelling formation damage, due incompatible fluid invasion, common problem in petroleum industry. In this research, effect Acanthophyllum root extract (ACRE) , bio-based surfactant, on reduction reservoir permeability impairment has been studied. Some static tests were applied investigate chemical interaction between surfactant and montmorillonite (Mt),...
