Ab initio molecular dynamics investigation of CH4/CO2 adsorption on calcite: Improving the enhanced gas recovery process
Carchini G.; Al-Marri M.J.; Hussein I.A.; Aparicio S. ( American Chemical Society , 2020 , Article)Ab initio molecular dynamics simulations of CH4 and CO2 on the calcite (104) surface have been carried out for the molecular level analysis of CO2-enhanced gas recovery process (EGR). This process takes advantage of the ... -
Ab Initio molecular dynamics of the dissolution of oilfield pyrite scale using borax
Onawole A.T.; Hussein I.A.; Ahmed M.E.M.; Saad M.A.; Aparicio S. ( Elsevier B.V. , 2020 , Article)Iron sulfide scales, particularly pyrite, form in oil and gas underground tubing and surface equipment thus blocking the flow of fluids and halting production. Therefore, the development of physicochemical processes for ... -
