Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Polymeric formulations used for loss circulation materials and wellbore strengthening applications in oil and gas wells: A review
(
Elsevier B.V.
, 2019 , Article Review)
Drilling fluid circulation loss is referred to as “the most severe problem in drilling of oil and gas wells”, as a routine solution, loss circulation materials are added to fill any fractures and vugs that may have been ...
Influence of polyelectrolyte architecture on the electrokinetics and dewaterability of industrial membrane bioreactor activated sludge
(
Academic Press
, 2019 , Article)
Improvement of sludge dewaterability is greatly hindered by the presence of large amounts of interstitial water molecules trapped in the sludge as a result of strong hydrophilic characteristics. This study has investigated ...
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 ...
A study on stability of active layer of polymer solar cells: effect of UV–visible light with different conditions
(
Springer Verlag
, 2019 , Article)
The objective of this study is to investigate the stability of the active layer of polymer solar cells from the effect of UV–visible light irradiation using different conditions with respect to time. The active layers were ...
