Chromium removal from tannery wastewater by electrocoagulation: Optimization and sludge characterization
(
MDPI AG
, 2020 , Article)
The treatment of tannery effluent is of great interest as it contains a complexmixture ofpollutants, primarily chromium. The disposal of this wastewater can have adverse effects on the environment and aquatic life, which ...
Biotechnology for gas-to-liquid (GTL)wastewater treatment: A review
(
MDPI AG
, 2020 , Article Review)
Gas-to-liquid (GTL) technology involves the conversion of natural gas into several liquid hydrocarbon products. The Fischer-Tropsch (F-T) process is the most widely applied approach for GTL, and it is the main source of ...
Osmotic pressure estimation using the Pitzer equation for forward osmosis modelling
(
Taylor and Francis Ltd.
, 2020 , Article)
Forward osmosis (FO) has received widespread recognition in the past decade due to its potential low energy production of water. This study presents a new model analysis for predicting the water flux in FO systems when ...
A theoretical study of gas adsorption on α-quartz (0 0 1) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2020 , Article)
The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on the “dense” (0 0 1) surface of α-quartz has been investigated by means of Density Functional Theory (DFT) for the molecular characterization of Enhanced Gas ...
Synthesis and Characterization of Fe3O4 Nanoparticles Using Different Experimental Methods
(
Institute of Physics Publishing
, 2020 , Conference Paper)
This paper reports a comparative study on the synthesis of Fe3O4 nanoparticles using three different methods, namely; Co-precipitation, Sonochemical and Solvothermal methods. Ferric chloride hexahydrate (FeCl3.6H2O) and ...
Prevention of barite sag in water-based drilling fluids by a urea-based additive for drilling deep formations
(
MDPI
, 2020 , Article)
Barite sag is a challenging phenomenon encountered in deep drilling with barite-weighted fluids and associated with fluid stability. It can take place in vertical and directional wells, whether in dynamic or static conditions. ...
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales
(
American Chemical Society
, 2020 , Article)
In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown ...
Hole cleaning and drilling fluid sweeps in horizontal and deviated wells: Comprehensive review
(
Elsevier B.V.
, 2020 , Article Review)
Horizontal wells provide high drainage area within the reservoirs. Advancements in horizontal drilling technologies are utilized to develop unconventional resources such as shale gas and coal bed methane. However, wellbore ...
Applications of chelating agents in the upstream oil and gas industry: A review
(
American Chemical Society
, 2020 , Article Review)
Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, ...
Predicting carbonate formation permeability using machine learning
(
Elsevier B.V.
, 2020 , Article)
It is imperative to characterize the formation permeability to simulate the flow behavior at subsurface conditions. An accurate characterization at the core scale is possible when large samples are available, but often ...
