HTTP:: Graphene Sheet in Oil Wells Could Make All the Difference
--------
The economic factor is one of the main things that dictate whether an oil well will be opened or not, economists say. Experts at the Rice University have recently entered a new research effort, aimed at producing a nanometer-thick layer of graphene that would constitute an additive for average drilling bits. The innovation, which the RU team is working on together with colleagues from Houston-based M-I SWACO, could make all the difference between oil wells that make a substantial profit and those that barely pay for themselves, the university reveals in a press release. The main purpose of the graphene additive will be to create a thin filter cake on the walls of the boreholes, and to keep all pores in their surroundings open. This may ensure a clear and steady oil flow from the underground deposits to the surface, and eliminate the need for very cost-intensive maintenance work. Only trace amounts of additives will have to be added to the barrels containing the average dr!
illing fluid, the scientists report. “People often ask me what are we developing, and most of the time they want to know what's coming out tomorrow, next week, next month or next quarter. In reality, I have to worry about things we're going to implement two to five years from now. That's where the step changes are. Th...
