Thermochemical Upgrading of Calcium Bentonite for Drilling Fluid Applications
(
American Society of Mechanical Engineers (ASME)
, 2019 , Article)
The rheological properties of bentonite suspensions depend on the chemical composition and the contained dominant element, such as calcium (Ca), potassium (K), and sodium (Na). Na-bentonite type is the one used in drilling ...
Impact of Surfactant on the Retention of CO2 and Methane in Carbonate Reservoirs
(
American Chemical Society
, 2018 , Article)
Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and ...
Development of efficient formulation for the removal of iron sulphide scale in sour production wells
(
Wiley-Liss Inc.
, 2018 , Article)
Iron sulphide scale, which exists in different forms, is common in sour oil and gas production wells. Iron sulphide hard scales are difficult to remove with acids, requiring mechanical intervention or the replacement of ...
Clay minerals damage quantification in sandstone rocks using core flooding and NMR
(
Springer Verlag
, 2019 , Article)
Sandstone oil reservoirs consist of different clay minerals such as kaolinite, illite, and chlorite. These clay minerals highly affect the formation damage during enhanced oil recovery (EOR) and well stimulation operations ...
Molecular Modeling Study toward Development of H2S-Free Removal of Iron Sulfide Scale from Oil and Gas Wells
(
American Chemical Society
, 2018 , Article)
A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales ...
Pyrite Scale Removal Using Green Formulations for Oil and Gas Applications: Reaction Kinetics
(
American Chemical Society
, 2019 , Article)
Pyrite is one of the toughest iron sulfide scales to remove, which causes major problems in oil and gas production by damaging production equipment. The use of inorganic acid in iron sulfide scale removal particularly ...
Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
(
Elsevier Ltd
, 2021 , Article)
Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ...
Carbon dioxide EGR and sequestration in mature and immature shale: Adsorption study
(
Elsevier B.V.
, 2020 , Article)
Recently, CO2 sequestration in different shale formations has become an attractive option owing to the abundance of shale basins. However, these formations have different maturity levels and contain a variety of minerals ...
Dissolution kinetics of different inorganic oilfield scales in green formulations
(
American Chemical Society
, 2020 , Article)
Scale mineral deposition is a critical problem that hinders the daily production of oil and gas fields. Chemical removal of these scales, based on the scale type, is common. In this paper, borax and diethylene tremaine ...
Ab-Initio Molecular Dynamics investigation of gas adsorption on α-quartz (001) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2021 , Article)
In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...
