Oilfield chemistry

The effects of aging and temperature on the performance of one-part “just add water” granite based geopolymers are studied for application in well cementing and abandonment. Further studied is the role of zinc as a strength enhancer over a long curing period.
This paper presents the evaluation results of a water-shutoff agent based on an emulsion-type chemical material with nanoparticles.
The authors of this paper discuss the use of dissolved polystyrene waste for the preparation of nanomembranes for separation of hydrocarbon pollutants from wastewater streams.
