Filed:

Nov 29, 2017

Appl. No.:

16/463618

Inventors:

- CORNING NY, US
Weiming Li - Katy TX, US
Elias Panides - Horseheads NY, US

International Classification:

B24B 9/10
B24B 55/02

Abstract:

An apparatus for processing an edge of a substrate sheet. The apparatus includes a finishing member, a shroud, and a tubular member. The finishing member is rotatably maintained within a chamber of the shroud. The shroud includes a wall segment terminating at a major edge that defines a portion of a slot. The slot is configured to receive the edge of the substrate sheet, facilitating interface of the edge with the finishing member. The wall segment further defines a nozzle passageway that terminates at an opening in the major edge. The tubular member projects from the major edge and defines a passage in fluid communication with the nozzle passageway. Cooling agent delivered to the nozzle passageway is injected onto the finishing member via the tubular member even in the presence of vacuum induced cross-flow. In some embodiments, a spatial arrangement of the tubular member is adjustable.

International Classification:

C09K 8/64
E21B 43/26
E21B 43/267
C09K 8/72

Abstract:

A treatment fluid for use in a combined acidizing and proppant fracturing treatment, the treatment fluid comprising: (A) an emulsion comprising: (i) a continuous oil phase; (ii) an internal aqueous phase comprising: (a) water; (b) a source of hydrofluoric acid; and (c) a source of acid other than hydrofluoric acid; and (iii) an emulsifier; and (B) a proppant. A method of fracturing a treatment zone of a well, the method comprising the steps of: (I) forming a treatment fluid; and (II) introducing the treatment fluid into the zone at a rate and pressure greater than the fracture gradient of the zone.
