Screening of surfactants and polymers for high temperature high salinity carbonate reservoirs
(
Society of Petroleum Engineers
, 2018 , Conference Paper)
Carbonate reservoirs typically exhibit significant heterogeneity, high temperature and high salinit ies. Surfactant and polymer selection for such reservoirs is a challenging process where extensive laboratory investigations ...
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) ...
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 ...
Effect of CO2 content on the natural gas production from tight gas sandstone reservoirs
(
Society of Petroleum Engineers (SPE)
, 2017 , Conference Paper)
The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas ...
