Multi-slug staged method for plugging fractured formation
A multi-slug staged method for plugging a fractured formation includes: determining an average opening of fractures around a well as D, an average particle size of bridging particles for first-stage plugging as D.sub.1 that is slightly less than D, and average particle sizes of plugging particles for second to last-stage plugging as D.sub.2-D.sub.n, where D.sub.n is small enough to form a tight plugging layer; and sequentially injecting a plugging slurry only containing the bridging particles having the average particle size of D.sub.1, plugging slurries containing the plugging particles having the average particle sizes of D.sub.2-D.sub.n-1, and a plugging slurry containing the plugging particles having the average particle size of D.sub.n into the fractures to achieve the fractured formation plugging.

GRANULATED ADDITIVE BASED ON TEXTILE FIBRES FROM END-OF-LIFE TYRES (ELT), TYRE POWDER AND ASPHALT BINDER AND METHOD FOR OBTAINING THE PRODUCT AND USE
A solution to the two major problems that exist today, on the one hand, by recovering the textile fibers extracted from the recycling and Processing of ELTs and, on the other hand, by providing the asphalt paving industry with an alternative mixture with superior performance to that of existing conventional mixtures. More specifically, a granulated additive based on textile fibers and rubber powder from end-of-life tires, having (a) 20% to 30% of textile fiber composed mainly of polyamide or polyester fibers, which together are of the order of 10% by weight of an ELT, (b) 20% to 50% of asphalt binder, (c) 25% to 45% of rubber powder from end-of-life tires in a fraction smaller than 0.5 mm, and (d) 3% to 10% of rubber powder from end-of-life tires in a fraction smaller than 0.18 mm. In addition, the method for obtaining same and its use in asphalt mixtures.

System and method for generating tire rubber asphalt
A method and system for generating a tire rubber asphalt compound is described. The method includes receiving an asphalt compound and heating the asphalt compound to approximately 320° F. to 420° F. The method then proceeds to add tire rubber to the asphalt compound. The asphalt compound and the scrap tire rubber are mixed for approximately 5 minutes to 360 minutes during heating to approximately 525° F. to 700° F. to generate the tire rubber asphalt compound. The tire rubber asphalt compound is then cooled.
