In this paper, the research and application of nanomaterials in oilfield chemical engineering was briefly described with emphasis on nano-silica enhanced oil recovery, depressure augmented injection. A study modification carried out indoors, a modified nano-depressure injection agent prepared by using coupling for surface grafting modification, followed introducing functional monomers in-situ m...

Abstract: In this presentation and article, we synthesize findings from a workshop about our understanding of the interplay between crude oil photochemical oxidation spill response, emphasizing how has evolved since 2010 DWH spill. Our discussion is guided by one overarching questions: what role does play towards informing effective response operations? We show that prior to spill, relative imp...

Guest Editorial Disasters and their environmental and health consequences know no bounds. Although no geographic area or population is exempt from natural or manmade disas­ ters, Louisiana and its neighboring coastal states on the Gulf of Mexico have had more than their fair share over the past 5 years. The latest environmental disaster is the BP Deepwater Horizon oil spill, which began on 20 A...

Highly pure and well-dispersed yttria nanocrystalline powders were synthesized with a modified coprecipitation method that uses mixed ammonium hydroxide-carbonate solution as the precipitant poly acrylic acid (PAA) dispersant. Comparing using same route but without PAA dispersant, PAA-assisted exhibit lower level of agglomeration better sinterability. Sintering trajectories dispersant investiga...

Simulating the Effects of the Circulation and Synthetic Dispersants on the Subsea Oil Transport” T comments by Adams et al. question the validity of our assumed oil droplet size model, which we deployed within a numerical simulation to describe oil transportation through the water column after blowout. Oil droplet size estimates may be the most significant unknown variable in oil transport stud...
