Metal oxide/metal sulfate water splitting cycle for hydrogen generation
(
AIChE
, 2017 , Conference Paper)
This study reports the thermodynamic analysis of the cobalt oxide - cobalt sulfate (CoO - CoS) based water splitting cycle. CoO-CoS cycle consists of two steps: first step - exothermic oxidation of CoO via water splitting ...
Chromium doped ceria for solar thermochemical fuel production
(
AIChE
, 2018 , Conference Paper)
In this paper, the thermal reduction and CO2splitting ability of Ce0.9Cr0.102-δare investigated by performing multiple thermochemical cycles using a thermogravimetric analyzer. The Ce0.9Cr0.102-δmaterial is successfully ...
Ceria-lanthanide-silver oxides for solar thermochemical conversion of CO2
(
American Institute of Chemical Engineers
, 2019 , Conference Paper)
This paper reports the thermochemical splitting of CO2 using Ce0.9Ln0.05Ag0.05O2-d materials, which are prepared by using the co-precipitation method. The phase composition and the morphology of the derived materials was ...
Mechanistic modeling of wellbore cleanout in horizontal and inclined wells
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
The accumulation of rock cuttings, proppant, and other solid debris in the wellbore due to inadequatecleanout remarkably impedes field operations. This article presents a new hole cleaning model, whichcalculates the Critical ...
A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory, in order to investigate the molecular characterization of Enhanced Gas Recovery (EGR) ...
Development of oil formation volume factor model using adaptive neuro-fuzzy inference systems ANFIS
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
The oil formation volume factor is one of the main reservoir fluid properties that plays a crucial role in designing successful field development planning and oil and gas production optimization. The oil formation volume ...
Investigation on the effect of mud additives on the gelation performance of PAM/PEI system for lost circulation control
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
Lost circulation is one of the most common problems in the drilling of oil and gas wells where mud escapes through natural or induced fractures. Lost circulation can have severe consequences from increasing the operational ...
Application of DFT in iron sulfide scale removal from oil and gas wells
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ...
Gelation Performance of PAM/PEI Polymer-Based Mud System for Lost Circulation Control
(
EAGE Publishing BV
, 2021 , Conference Paper)
Lost circulation is one of the most common problems in the drilling of oil and gas wells where mud escapes through natural or induced fractures. Lost circulation can have severe consequences from increasing the operational ...
Reinforcement of polyacrylamide-co-tert-butyl acrylate base gel using nanosilica for conformance control at low and high reservoir temperatures
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
Challenges of water shut-off, which is categorized under conformance control, are nowadays common in the oil and gas industry. The excessive water quantities produced from oil reservoirs can make the production process ...
