..., and a water-wetting surfactant. The treatment fluids were displaced into the formation by pumping diesel. The treatment fluids were allowed to soak for 6 hours, then the well was put into production, and samples of flowback fluids were collected. The concentrations of key cations were determined using...

... filled reactors to determine the critical parameters on recovery. Laboratory tests were complemented by conducting experiments using air at different O2 concentrations: zero (i.e., nitrogen), 21.0 mol% (air), and 37.3 mol% (O2-enriched air). For safety reasons, it is imperative that enough time be given...

... of treatments. The Beaverhill Lake formation is a limestone/calcareous shale that produces a desirable mid- to high-API sweet crude oil. Although the crude oil typically has a low concentration of asphaltenes, the oil is sensitive to acid and/or iron-induced asphaltene precipitation. As the acid strength...

The pressure drops in different segments along length of the sandpack were monitored continuously. The retention behaviour of particles at the end of each experiment was examined by measuring the catalyst...
